Does anyone else get tricked into trying to wipe away Sean's doorstop from the screen?
Every. Single. Video
Try 70% Isopropyl Alcohol.
Yes.
We installed AGM Batteries four years ago and just ordered some Rhino 3 Lithium batteries. We did this because at the time AGM was cheaper and 100% recyclable plus we'd get paid for them to recycle. lithium at the time wasn't recyclable and were dangerous. Our plan was to buy cheaper batteries to get us through as many years as possible in the hopes technology would get better. It has but I wish sodium batteries were an option today. The Rhino 3 is a older battery being discontinued as we got a heck of a deal on them. About half the cost of our AGM's with more than twice the capacity. These new Rhino 3 batteries should last twice as long so by the time we have to replace them I can't imagine where battery tech will be.
Arbitrage *THIS*! Last I checked, San Diego Gas & Electric offered a "super off peak" residential rate, 10:00am - 2:00pm.
Thanks for answering my question! It was prompted by Fisker potentially selling off their remaining cars for as little as $14,000 - literally buying a cheap EV for no other purpose than being a battery.
My geology instructor (probably a decade ago) did her doctoral thesis the previous year on the decontamination of ground water. The gallon had toxic levels of jet fuel and it took her a month in a university lab to make it potable...
My comment isn't related to the show but It would be cool if you could talk to the owners of you old house and their thoughts and feelings about it after a year of living in Matt's old house.
Poor Sean, He looks like he's melting, 😂
Here in Canada we are just about ready to get electricity 🤣
Heat scavenging is best achieved by having all of your heat sources in one utility room. New German homes have these. Fridge and freezer compressors can be detached and extended to operate in the utility room rather than the kitchen. You can install a vent fan behind the oven to draft air past it and into the utility room or outside. Putting your server rack into your utility would be a huge gain to you personally.
Regarding your electricity bill credit, here in Texas solar has become so popular that power companies (yes plural, it's Texas) have implemented monthly caps as it was impacting their bottom lines. I went for 4 years without paying an electric bill, but now I do have to pay the connection fees, taxes, and an occasional small electric bill in the winter if I don't hit the cap. No more accumulated credit. I expect time-of-use to eventually go away here as EVs become more popular and everyone is charging them overnight, and charging house batteries from the grid overnight could impact that as well.
All of that is merely a change in policy and/or regulations. Hopefully everyone can adopt to these type of changes fairly easily. It has definitely had its challenges for me, but I am more or less back to net zero overall.
Here we have annual accumulated credits and in December the power company pays you whatever is left.
3:41 "Battle scene from Ben Hur" You really dated yourself Sean! 🤣
Speaking of weather, you should have been in Houston when hurricane Beryl decided to waltz though! 75 MPH winds with that heaping helping of rain.
For your server room to water heater heat pump, all you need is an 8” duct and your heat pump has a way to attach a duct to either the air intake or output.
7:40 Heat exchangers work: but the difficulty is that you don't want to send particulates from your kitchen , laundry, and bathroom through your heat exchanger.
So you need to add what are essentially HEPA filters to the line, which would require periodic replacement.
Not replacing the filter would be a fire hazard.

Thank you for this presentation. I have been studding the recent evolution of the power grid. I enjoyed you comments. about not going Off Grid. I live in the American southeast and think that we down hear are playing catch-up. Also, I watch a lot of other UA-cam video and many are anti-renewable energy. It is almost like they are reading from the same script. To them, I mention what is happing as the grid decentralizes towards more consumer participation, but none seem to get the idea. The consumer making money is a dangerous idea.
Best heat reuse I’ve employed was crockery storage above a chiller for warm plates. Here in Britain “standard” electricity is 25p/kwh, between 16:00 and 19:00 it’s 36p, but there are 2 cheap rate periods 04:00-07:00 & 13:00-16:00 of 12p on a tariff called “Cosy Octopus”
the problem is each power company has its own regulations and programs. each state has hits own regulations and programs. I mean li live in "the county" but across the street it is "the city" so latterly across the street different regulations apply
My current goal is to produce at least 120% of my summer electric bill. And considering here it's pretty much summer all year long means we gotta be blasting the AC pretty much all day.
I watched a video that talked about how a server farm's heat us being used to warm up the Olypic pools in Paris. And how they are trying to find other ways to use that heat, like for green houses.
Great video as always.
Not sure whether they are directly applicable to the USA in terms of type but we have many many more options available in the EU/UK/Australia than you appear to have readily available (ie not directly imported from China).
|I suggest having a look at SigEnergy - it's available in Single 3/4/6/8/10/12kw and Three Phase upto 25kw versions that stack on top of upto 6 batteries (currently available in 6/8kwh with 10kwh coming next year). Each battery is a self contained unit with its own integral BMS. You can swap out one of those battery options for a V2X 15kw or 25kw DC EV Charger that can draw from Solar PV, Batteries and Grid at the same time. Further you can parallel multiple stacks of inverter/batteries. Connected to a Gateway device which has 0ms switchover (compatible with Medical Devices ie Respirators etc) the simpler, residential, gateway can take 3 parallel stacks - so potentially 3 x 6 x 8 = 144kwh (or 180kwh when 10's are available).
that's a very NYC 4th! Glad you guys haven't melted away. It's been grot here in PVD, too.
12:35 “hammering the battery of your car” I have my BYD Seal’s V2L connected to the “Grid” input of my solar inverter (I don’t have a grid connection - I’m off-grid) I can power my house all night and use 8% of the car’s battery equivalent to 46km of range loss. I can charge that back in less than an hour. I have 36kWh of LFP solar batteries and my car has 86kWh (gross) LFPs. The car is actually much more efficient in it’s use of power than my solar batteries. In terms of cycles my house batteries on their own cycle once every 2 days, the car would be over 12 days. (Videos on my channel)
I have a second home in VT. I tried to get Tesla to install soalr and battery but Tesla gave me a bit of a run around about my roof. I replaced the roof and still they cancelled my order. So i then just ordered a Powerwall from Tesla. They installed that. I signed up with VT's Green Mountain Power virtual power plant so they can use my battery to maintain the grid. So far it happens about once or twice a month. They pay you up front for the kWh they can use so they paid me about $3600 when I signed up for 10 years. That is great as it helps off set the cost of the battery up front but I would prefer to get paid per usage. I doubt they will abuse the battery but only time will tell. I am now installing a small solar system myself from Wholesale Solar so I can get some solar power as well. It is just over 3kW.
thank you for another thoughtful talk
Financially maybe not, but i very much want to reduce my impact on the grid, so yes
Both Australia and California are now having solar surplus at various times of the day. So enjoy your profit taking now before they shut you down and not buy your solar power which then will increase your utility bill.
Too much power is a nice problem to have if you can do meaningful load shifting.
I have a reason to use a car as your battery. Old Nissan Leafs go for 5k with a 20-30kwh battery.. it’s cheap and supports V2G… who needs to drive the battery?
Have been having trouble finding CHAdeMO equipment in my searching.
Fireworks in 2024 🤦
Basically left versus right conservative versus liberal or progressive. Are just labels that are convenient and lazy. Go through issues one by one or go through legislation and policies implemented one by one without telling the people whose idea it is or labelling the idea. There is so much commonality. For example, the minimum wage, getting paid a fair wage or a fair share of profits, the discrepancy between the wealthy and everyone else, a single bear healthcare system, and so on. There have been coal miners on strike that literally want nothing to do with Bernie Sanders or the left. There are so many examples where lables skew thinking such as government programs bad but social security good, government health care bad but Medicare good.
