The truth is - both are extremely impressive The big 100kW inverter needs to produce "clean sine wave" with the perfect Hz-count. Thats why it is so big. The little one can feed like "dirty sine wave" to the self-sufficient eCar motor. But still - it is able to do that at this like tiny amount of space. Greetings from a german engineering highschool
Also for the size difference on the inverters between the grid tie and the motor inverter. The grid tie for one has to be 100kw continuous and two has to provide that 100kw very clean so it needs many extra filtering and safety components in it to be able to send power back to the grid. The motor driver may do an 80kw transient peak but I guarantee that little box will not touch 80kw for longer than a few seconds. Motors typically take lots of power when speeding up especially in electric cars, but once you reach your speed they only run continuously at somewhere around 5kw to 20kw. The grid tie inverter also needs to convert voltages it may need to step up or down depending on the pack voltage. That car inverter most likely just takes the pack voltage and chops it up to feed a 3 phase motor. We are comparing apples and oranges here. Great video though and thank you for sharing! I found the video very interesting.
Great answer !! In addition creating 60 hertz forces you to use huge inductors. His motor controller can run at a much higher frequency which lower the duration of the current spikes and the size of the inductors by a huge amount.
how much does it cost for an electric car is about 600 bucks if you salvage an electric forklift for 500. up to 100k if you want a long range and high power EV..
The negative ground sounds right many grid tie inverters are either negative or positive grounded and negative is the more common of the two. The ground has to be referenced to something or else what good is it? Usually we say the negative side is 0v or ground and the positice side is say 600v with respect to the negative side or with respect to ground.
Jehu, there is a big difference in true sine wave inverters compared to the digital ones you use to drive a motor. When driving a motor it does not care if you have square wave or sine wave, it works on both. But the Mains care a great deal of the signal is sine or not so all the components are for creating a proper sine wave.
The two inductors and secondary capacitor bank form an LCL filter on the AC side of the inverter. The cabling for the caps does not need to be as large as that on the inverters output as it does not carry the full load power. The reason that the large box is so large when compared to your motor drives is primarily due to the filter components (which are generally not required for motor drives), and the water cooling.
It also seems to me that the large inverter could do 100kW for years with no sweet, where the smaller can only deliver 80kw for a short time and would probably shut down or catch on fire at full output after a few minutes. Even if it is 95% efficient, it would still have to dissipate 4kw worth of heat.
Man, I'm in love with that kit! Four years ago I spent $2500 on a Magnum 2.8kw and four lead-acid batteries (4.8kwh usable) for my RV... Someday I'd like to replace these beastly lead-acid with some lithium goodness.
Princeton Power has a patent on a unique way to generate three phase AC from DC. That explains all the inductors and capacitors you saw. The schematic would be available from the published patent.
Tell your motor controller to output 60hz ;-) ( not the 5~25khz switching or whatever they do make i think they motor is spinning slow) , check with a scope ( you may need a filter) and then split the phases ( a used datacenter rack PDU ) and hook up some loads ( 3 mig welders? ) and see what happens. I've been wanting to try but have spend my resources in other places.
Remember nearly all autos and mobile vehicles are grounded DC negative. :) Yes you can have AC caps, they are used mainly for power factor correction, phase adjustment, and motor starting. The electronics for creating 3 phase AC that can be synced up to the Power Grid is much more complex than the inverter/controller for your bus. The inverter in your bus can run at any frequency and it won't really matter as long as it will power your motor. In addition to that i don't believe you have a real AC inverter in your bus ... you have really a controller which simply decided how much power to send to your motor based on your "gas pedal". That is a lot different circuitry. Lastly creating 2,000 hertz AC at 100 KW would shrink all those huge transformers and inductors by a factor of 6 to 10 times. so the size and weight of that system would shrink a lot!! ... But you can't sync to the power grid if deviate from 60 hertz by more than .25 cycles.
I've been researching options to install a 30-40kWh battery backup solution to work with my 9,860 watt solar PV system. My goal is to get completely off the grid, or at least only draw from the grid rarely. I've been thinking about buying 6 Tesla modules and an inverter, but interested to hear from the expert.
One other thing you will be putting all your eggs in one basket. With only one large inverter it is all or nothing. These things do break down and then you have to go on bypass and hope nothing happens to the normal power. We found it better to go with multiple smaller inverters that would sync together and have one more than we need for a spare. We did 100kw for our computer room where we used 5-25 kW inverters that load balances on one panel where you could lose one and still met all your needs. The chance of two going down at one time is small compared to your one inverter breaking down. I can tell you it will break down in the middle of a storm on a holiday when you are running a backup that can not be interrupted. These things love Murphies law Beter to be safe than sorry. I would never use one large inverter over many smaller ones. I ran and designed computer rooms for 24 years take this as advice from someone who has been there. Good luck
Thanks for the fantastic video! I really like to watch such devices, technological solutions, etc. It came to my mind to answer your question about the difference in size between these devices. Well, size is a derivative of many things. The large inverter is built with IGBT technology, and you can see very large IGBTs as well as huge capacitors are used. Probably they do not have a large capacity, probably up to several hundred uF, but they have very low ESR, conduct huge currents, must be well cooled and must work for many years. A lot of space in the wardrobe allows for easy replacement and assessment of damaged elements. The cabinet is designed to be installed near a solar farm, it needs to be remotely controlled by this huge three-phase contactor. The inverter must have appropriate power supply connections for IGBT modules and power connections - this takes up a lot of space and must meet industry standards. This type of device is also to ensure the best quality of the current supplied to the network, which is indirectly ensured by these huge coils at the bottom - they are used to extinguish the voltage spikes and store and return energy from IGBT modules, which work in PWM mode, probably around 20kHz. The device is subject to professional supervision of electricians, so it must meet the standards, including safety. This all explains the size of this 100kW solar inverter. A car inverter does not need to have almost any of these features. This 80kW, if I remember correctly, the one you show at the end, when it breaks down, do you know what you can do with it? ;) And that is the huge difference between these inverters. Besides, I think that advances in SiC MOSFET technology will change everything. From such a cabinet it will be possible to achieve 10MW soon, not a paltry 100kW.
that is massive, i hope it woerkd well , i would love that magnum inverter. hope its still available, i agree with the car being more impressive but i would stil love a magnasine
Hi jehu! Two words to explain the difference between that 100 kw inverter and the pair of smaller inverters that are making 140-150 kw: Duty cycle That big 100 kw inverter can run at its rated power for 24 hours a day, 7 days a week, 365 days a year without breaking a sweat. Try that with the two smaller inverters that are making 140-150 kw and they would melt.
Be careful with this unit, if the input battery negative is earthed as shown you will have to also install an AC isolating transformer to the set up, thats what the left hand bottom sets of terminals were for, did you get this transformer with the set up ?, if not it could be expensive !, very interesting to look inside this unit......
The difference between the two inverter can be pictured easily by thinking about engines. A 500hp 3.0l V6 engine from a fast family saloon/sedan may have the same power output as a big diesel engine in a 28ton truck but you definitely can't use an Audi RS6 engine in a heavy hauling truck pulling 30tons of cargo
AC systems are only grounded by choice. Makes sense to just stick that negative wire in the ground to ground the system. Also similar to a car chassis being grounded.
The big one is 100KW of 3-phase with multiple sources (solar, wind, hydro, battery & grid) and multiple outputs...including the ability to sell power back to the grid. The little one is 80KW single input (battery) & single output (motor).
both inverter may be 3 phase but there functionality is day night different. I think the phase difference voltage is the first thing. phase difference voltage is double of what the actual voltage is like 110 v is 220. and also 120 degree shifted. In motor controllers the phase difference voltage remains the same as the battery voltage however its switched precisely by igbt's is such way that the motor forms a rotating magnetic field. And the second thing is we can run single phase induction motor by taking any of the 3 phases and ground connection but ev inverters not possible. correct me if i am wrong, i do appreciate it.
I have a Hustler Zeon electric zero turn mower and would like to install some of your lithium batteries to replace the lead acid batteries it has now. What do you recommend?
I just bought a new dubble wide 1600sq ft all power.. I havent had the power hooked up as of yet. what would it take to run that house. is there a Power Inverters that will hook up inplace of my P.M.?
Jehu, thanks for the video. How much is the 50KW, 3-Phase inverter? Where in U.S.A can I get a new or fairly used one?Does this inverter comes with charger to charge a 100KWH LG 16S Battery Packs?
Regarding the sizes of the inverters: the static one is designed to run at 100% duty cycle, all day every day. The drive inverters in EVs are designed to run at, say, 20% duty cycle, i.e. steady 70MPH with the odd blip when accelerating. When working hard, automotive inverters get heat soaked and de-rate until load drops. That's acceptable in a car, not so much a factory :-) Intel plays the same game with their chips: they have a TDP or Thermal Design Power, meaning they can't run everything at full speed all the time without throttling down to reduce head production until the heatsink can catch up. If you could pull the heat out of your automotive inverters quickly enough you can probably up-rate their duty cycle, but fitting all that cooling in a car can be a real packaging problem, especially if you can't get coolant in sufficient quantity to where the heat is being produced (like Tesla's watermellon-sized drive inverter).
Hahah, you have no idea how much I want to replace my APC 48V UPS (my makeshift solar inverter) with one of those guys :D My 4x110Ah batteries would also like replacement :D A shame I am in Europe! Great videos though! Cheers!
Mainly the output caps are for Balancing the power factor as well as the inductance, and the power board governs them, white thing on the output. This is to keep the invert near a power factor of 1 and don't blow the igbt. The size of this invertrrr is big due yo this, the one in your car is design for and engine and this one is ready for a bunch of more complex loads.
I checked out the link. Is that the lowest you'll go on one of these bundles? I want to be able to power my 48000 BTU central A/C but the inverter is just slightly too low so, if I bought this bundle, I'd probably end up having to replace the inverter and be tasked with trying to sell it.
One of the big guys must be designing a battery for large scale that solves the heat problem that is a much larger battery than 18650. Something about 2lbs in weight or more in a solution with fins for cooling. that contains 1kW per hour or more. This technology will be very short term give it a year. It will change massively.
your motor controller doesn't have to change voltage. keep it regulated. the controller is basically a MOSFET switch that turns the power on / off a few thousand times a sec. which is what a inverter does and lots more.
jehugarcia I didn't know that. I guess I need to get my foot out so I can talk. I have been attempting to build a inverter. since I am having trouble buying one. your channel is very interesting.
+Jehugarcia , I'm doing an off grid house battery/solar, Interested in 2 inverters, and 36kwh of batteries. Do you have the data sheet for the batteries, and cycle info for them (tested/untested)? What kind of a deal could you do for those quanties?
Awesome, thanks ended up buying 2 of these for now, later I can add more cells. Looking forward to watching you wire up this MWH battery. Love your channel!
Film caps are probably better ...but are more expensive.. A Google search for some white paper will help....what this inverter is using I don't know.. but film is better...
The giant inverter is more impressive compared to what's used in cars for the same reasons that giant motors that output the same power as the much smaller ones used by EVs for a simple reason, time spent at peak. With a car you won't spend the energy in the battery pack doing peak discharge and peak loading the motor, if you did, they couldn't handle the heat. The large industrial ones are designed to work at those powers all the time.
Dude make sure you have a way to isolate it from your output so it can be worked on and you do not lose your load. Don't just use the internal bypass because most of them keep the caps charged so it can switch back instantly. It makes it so you can not change the caps without powering down the whole thing. The cap that gives you a true sine waveform only last about 10 to 15 years of use and then they start to fail and your waveform starts to step. So make sure you have an external bypass that is a make before break so you can bypass your inverter without dropping your load. This way you can work on and replace it when it wears out. Trust me, do this during install because it is too hard to do after the fact when it is being used.
I'm designing an investor 100kW for hybrid yacht with electric propulsion, PV, microgrig with 2 Gens, and sure Gridtie. Pleas let me know if you need help
Thinking the 2 big white things are SCR's aka thyristors... not sure of the difference between IGBT and SCR? I got a little confused because I think you said the DC was passing through a transformer? usually the DC switching is done first to create AC then passes through a transformer to acquire the desired volatge. I imagine the caps are there for smoothing. Also I've used VFD's as off grid shop inverters for 3 phase power by just tapping DC into the buss bar. VFD's should be able to function as a grid tie inverter since most have the ability to regen into the grid. I've always wondered about using industrial VFD's a motor controller for EV's? I thpugjt this was an interesting comparison of mosfet vs igbt vs scr. electricalvoice.com/comparison-of-thyristor-mosfet-igbt-devices/
you know how mad I am not been able to aford the bundle I am just 17 tried soo many job applications nothing every job around me is full I been into this for 7 year my first solar panel was a 5watt stolen some 165 w solar panels were donated to me but they were broke shatered glass only produced around 30 watts I been charging 4s laptop batteries I got from school for the past 3 days no charge controller no bms no safety aaaaaaaaaaaah I so hate my life I been trying to get an inverter woo baddly I found one in a trashcan I think its 200 watts but with no cover or Idk what its max power output it just a bare board worked for a while but battery voltage was high caps blew
I never thought your main value entertainment. That was a side benefit, much appreciated. Your main value was informative. Your fearless investigations, experimentations, projects solving problems, being creative and actually building something useful. I hope this was also an inspiration for DIY - Do It Yourself. Something I think our modern world is lacking, here in America. Aspiring to be a celebrity and entertaining - well maybe hard to avoid in California. Kids have so little opportunities to be creative and you showed how it can be done, while changing the world to solar power and electrification of transport.
PS - you could study electrical engineering, on your own - DIY style. Use the internet, avoid "schools". Seems many here would help. We all should be much smarter/knowledgeable about electricity. right? You already know each journey/project starts with just one step.
The truth is - both are extremely impressive
The big 100kW inverter needs to produce "clean sine wave" with the perfect Hz-count.
Thats why it is so big.
The little one can feed like "dirty sine wave" to the self-sufficient eCar motor.
But still - it is able to do that at this like tiny amount of space.

Can I ask you how much it cost for you to install it for someone else
Or how much it will cost for an electric car
how much does it cost for an electric car is about 600 bucks if you salvage an electric forklift for 500.
up to 100k if you want a long range and high power EV..
For Solarpanels on your roof, you need also a big and expensinve inverter..why?
3:30 those are inductors. They work with those smaller AC caps to smooth out the rough ac to sine waves.
The negative ground sounds right many grid tie inverters are either negative or positive grounded and negative is the more common of the two. The ground has to be referenced to something or else what good is it? Usually we say the negative side is 0v or ground and the positice side is say 600v with respect to the negative side or with respect to ground.
Yep
Jehu, there is a big difference in true sine wave inverters compared to the digital ones you use to drive a motor.
When driving a motor it does not care if you have square wave or sine wave, it works on both.
But the Mains care a great deal of the signal is sine or not so all the components are for creating a proper sine wave.
You need to move the Patreon link to the top of the description. You make good content and there's no shame in asking for support to make it possible.
those white things on the back are probably IGBTs they handle the main switching which produces the AC output. which Jehu later said in the video ahah
The two inductors and secondary capacitor bank form an LCL filter on the AC side of the inverter. The cabling for the caps does not need to be as large as that on the inverters output as it does not carry the full load power.

It also seems to me that the large inverter could do 100kW for years with no sweet, where the smaller can only deliver 80kw for a short time and would probably shut down or catch on fire at full output after a few minutes. Even if it is 95% efficient, it would still have to dissipate 4kw worth of heat.
+Brad Preece yeah it's really a 50kw continuous inverter
jehugarcia wrong! 25
Man, I'm in love with that kit! Four years ago I spent $2500 on a Magnum 2.8kw and four lead-acid batteries (4.8kwh usable) for my RV... Someday I'd like to replace these beastly lead-acid with some lithium goodness.
Princeton Power has a patent on a unique way to generate three phase AC from DC. That explains all the inductors and capacitors you saw. The schematic would be available from the published patent.
Tell your motor controller to output 60hz ;-) ( not the 5~25khz switching or whatever they do make i think they motor is spinning slow) , check with a scope ( you may need a filter) and then split the phases ( a used datacenter rack PDU ) and hook up some loads ( 3 mig welders? ) and see what happens. I've been wanting to try but have spend my resources in other places.
You are a VERY BRAVE man, to be touching caps and other things in a unit like this. Must have an 'in' with the Man.
+WesR not sure why everyone keeps saying this, I never touched the caps in the video
So.... ! Did that project got connected and working some where ????
Caps and transistors to make the voltage swing up and down to AC

The two white blocks are high voltage high current contactors
with energiser coils on the side
Your Jeep inverter only has to put out full power occasionally, the grid tied inverter must do so 24/7 hence the beefier devices and cooling.
Paul Gracey true although, You think the 100kw is the continuous rating of the Princeton? Or is it the peak rating?
One other thing you will be putting all your eggs in one basket. With only one large inverter it is all or nothing.

Hi jehu!
Two words to explain the difference between that 100 kw inverter and the pair of smaller inverters that are making 140-150 kw:
Duty cycle
That big 100 kw inverter can run at its rated power for 24 hours a day, 7 days a week, 365 days a year without breaking a sweat. Try that with the two smaller inverters that are making 140-150 kw and they would melt.

If that converter came from Telecommunications industry where Batt Neg is feed. Batt Positive is ground. Opposite of outside world vs telco.
Another jumpack video man!! Awesome!! Thanks for this!

can this be converted to single phase
Do you know when those cells will become available?

Can you power your house on the 13kw system you are selling?
+Maurice Mercado I currently use around 20kWh per day, But I have 2 EVs
I hope you will have luck with that big inverter..and i hope you got schematics from it..
Wow! I have never capacitors the size of coffe cans before?
What is the part number for those IGBTs inside?
I love how they got that beautiful blue transformer/inductor, right next to that crusty looking rusty transformer lmao
Mainly the output caps are for
Balancing the power factor as well as the inductance, and the power board governs them, white thing on the output. This is to keep the invert near a power factor of 1 and don't blow the igbt.

+James stranger my controller does regulate battery voltage 80v-130v to 96vac
jehugarcia
I didn't know that. I guess I need to get my foot out so I can talk. I have been attempting to build a inverter. since I am having trouble buying one. your channel is very interesting.
Jehu, on Combo Inverter and 13KW batteries... why is it 13KW spec.? Looks like less than 10KW, what am I missing here? $3K is a deal.
13kWh battery 4.4kW inverter Whats the confusion?
15S3P setup you show: 55.5V *180Ah= 9990 or 9.9KWHr. Where did I go wrong?
Because you get 12 batteries instead of 9? Picture has 3s3p, you're supposed to 3s4p
@2Awesome that's it. I see pic above on pallet is 12 modules. Math does work! Thanks
Yup I did make a mistake on that graphic turns out, but yeah 12 modules offered with inverters
The Bosch batteries are they new or come out of something?
Harry I I'm in a recycling facility, take a guess
Ok recycled, what did they come out of?
its complicated. im not at liberty to say until official channels break the story.
Thanks anyway keep up the good work.
The last one is a inductor filter.
Bro, that bundle is a hell of a deal unfortunately Im broke 😭😭😭😭😭
+Jehugarcia , I'm doing an off grid house battery/solar, Interested in 2 inverters, and 36kwh of batteries. Do you have the data sheet for the batteries, and cycle info for them (tested/untested)? What kind of a deal could you do for those quanties?
David Tucker II why do you need two inverters?
for now thats the only deal I have, in a not very distant future these batteries will sell for $150/kWh and $130/kWh when buying 75kwh or more
You can put them together and get 8800watts. Trying to setup a system to run a "modern" house.
Awesome, thanks ended up buying 2 of these for now, later I can add more cells. Looking forward to watching you wire up this MWH battery. Love your channel!
Can someone tell me what kind of capacitors are used in this inverter(100kw)?
for example Film capacitors, Electolyte capacitors or ....
Film caps are probably better ...but are more expensive..
A Google search for some white paper will help....what this inverter is using I don't know.. but film is better...
I would love to get that
These small inverters are still available or gone sell ?
Looks like Inverter from San Jose??
Are you selling any modules alone as well?
not yet
The giant inverter is more impressive compared to what's used in cars for the same reasons that giant motors that output the same power as the much smaller ones used by EVs for a simple reason, time spent at peak. With a car you won't spend the energy in the battery pack doing peak discharge and peak loading the motor, if you did, they couldn't handle the heat. The large industrial ones are designed to work at those powers all the time.
What happened to this project? Was it finished?
They wanted to only pay me $5k to do it
Is it a pure sine wave inverter ?
Dude make sure you have a way to isolate it from your output so it can be worked on and you do not lose your load. Don't just use the internal bypass because most of them keep the caps charged so it can switch back instantly. It makes it so you can not change the caps without powering down the whole thing. The cap that gives you a true sine waveform only last about 10 to 15 years of use and then they start to fail and your waveform starts to step. So make sure you have an external bypass that is a make before break so you can bypass your inverter without dropping your load. This way you can work on and replace it when it wears out. Trust me, do this during install because it is too hard to do after the fact when it is being used.
yaaay a new video, and second I think..idc really, AZ has been hotter, I don't really know...
very kewl ..thanks for the show and tell was great....
Jehu, can i buy some of these batteries?
will the inverter run on 24 volts
I'm designing an investor 100kW for hybrid yacht with electric propulsion, PV, microgrig with 2 Gens, and sure Gridtie. Pleas let me know if you need help
I would like to know updates, have you finished your project?
Thinking the 2 big white things are SCR's aka thyristors... not sure of the difference between IGBT and SCR? I got a little confused because I think you said the DC was passing through a transformer? usually the DC switching is done first to create AC then passes through a transformer to acquire the desired volatge. I imagine the caps are there for smoothing. Also I've used VFD's as off grid shop inverters for 3 phase power by just tapping DC into the buss bar. VFD's should be able to function as a grid tie inverter since most have the ability to regen into the grid. I've always wondered about using industrial VFD's a motor controller for EV's? I thpugjt this was an interesting comparison of mosfet vs igbt vs scr. electricalvoice.com/comparison-of-thyristor-mosfet-igbt-devices/
is this UL panel?
Will it run Crysis?
what is the price of this Invert er ??
what is the output voltage?
+We Are Miles From Nowhere 480vAc
jehugarcia wrong again 760
480 RMS 3 phase
I repair industrial inverter a great difference from home inverter
waiting for next video bro,...!
jehu , you are great !!!
how much?
For those of us that have no idea what that magna sine could do for us or what 13kwh can power, could you do a vid for dummies?
Asking for a friend.
magna sine is a beast. well, that also reflects on its price #ouch
forgot to explain... those long tubes are cables...
seems your electric inverter uses capcitors while my color inverter does not.
I need 4kw inventer or more :)
I realy can use some of this batteries
why not toroidal transformer
AC passthrough
Thanks
I wonder what ElectroBoom would think of this project. :p
How much $$$
Very interesting, but OMG, this thing is absolutely a no go where I am from. No proper colour coding and other safety features etc.
I was just waiting for his fingers to explode.
Im always guaranteed to disappoint
Those large DC caps are scary. Surprised you were getting so close to them.
I couldn't read the last part of your t-shirt. "yes I am a criminal..." help!
Maybe thats the end, Yes I am A criminal. according to my critics anyway
jehugarcia the t-shirt at 8:20. I can only see the top
curiosity?
fascinating! Weird about that ground.
the chassis is a good low resistance common voltage reference point.
Jehu Christ, I got seasick a couple of minutes in.
you know how mad I am not been able to aford the bundle I am just 17 tried soo many job applications nothing every job around me is full I been into this for 7 year my first solar panel was a 5watt stolen some 165 w solar panels were donated to me but they were broke shatered glass only produced around 30 watts I been charging 4s laptop batteries I got from school for the past 3 days no charge controller no bms no safety aaaaaaaaaaaah I so hate my life I been trying to get an inverter woo baddly I found one in a trashcan I think its 200 watts but with no cover or Idk what its max power output it just a bare board worked for a while but battery voltage was high caps blew
3 phase you must use a formula
IF YOU DO NOT KNOW do not say anything !
oh, geez....
100kW inventor in my car is 100x smaller.
did you know touching the wrong thing could kill you? capacitors and hold a lot of power.
sven bleeding resistors
just be careful. you cant see electricity
Can't you find diagrams? or manuals?
Watching your guess at parts, no so interesting.
you are not entertained? refund for you
I never thought your main value entertainment. That was a side benefit, much appreciated.
Your main value was informative. Your fearless investigations, experimentations, projects solving problems, being creative and actually building something useful. I hope this was also an inspiration for DIY - Do It Yourself. Something I think our modern world is lacking, here in America. Aspiring to be a celebrity and entertaining - well maybe hard to avoid in California. Kids have so little opportunities to be creative and you showed how it can be done, while changing the world to solar power and electrification of transport.
PS - you could study electrical engineering, on your own - DIY style. Use the internet, avoid "schools". Seems many here would help. We all should be much smarter/knowledgeable about electricity. right? You already know each journey/project starts with just one step.
Not sure what you think its going on here but I assure you, I know more today than i did yesterday, and tomorrow will be even better.
