Despite the good explanations, calling it a "secret" is pretty much click-bait for people who don't know the difference between capacity at the nominal voltage (Ah) and maximum charge or discharge current (Amps or C rating).
Thanks for a grounding view on the topic of electric gizmos & cars. BTW: would you consider making a video on grounding? I recently discovered, that it is not omnipresent and that there is a connection between health and lack of grounding.
Thanks for the informative and entertaining video, I never fully understood what the 'C' was referring to with the Lipo batteries I use for my rc cars until watching this video. You have an excellent way of describing things clearly and with a good sense of humor.
It's all sales tricks, marketing and politics. I learned decades ago buying my first rechargeable drill how pointless it was. Great if all your plan is to drill one or two tiny holes. Total waste if you bought it to compare to the electric one you had before. Barely get halfway through and "blub" In the back 40, no power, no drill, no holes. The new generation are much better, but then you get to problem two; Pay $$$ for the 2009 fancy drill etc kit and battery. Use it 12 times and it sits the battery goes dead. Go to buy replacement battery.. Sorry sir, you have to buy the new 2019 drill etc kit and new battery, we don't sell the model in your hand in ten years. The electric one from my teenage years still working 100% & it's drilling fine and used hundreds of times. What is "Green" Paying 100 for a drill and battery you use 12 times and throw in the trash Or one you use your entire life
My cordless (brushless) Makita drill with an 18V 5A battery is quite long-lived. Still, the cost of the tool plus chargers (they fail) plus batteries (they're crazy-expensive) is really not very economical compared to a corded drill. There is definitely a lot of, "BUY MORE STUFF!" involved...
@@ScottiesTech I remember those original Robin egg blue or sea green tools. They were much better but I couldn't afford. I still see the odd one at Flea Markets, missing the charger always. Old guys passing it around "oh boy remember these"
Battery everything is a trap. It’s bad. Everything The mainstream claims is better is not. Digital photography is a joke compared to film. Electric cars not only still requires fossil fuels, you can’t throw a spare Tesla battery in your extra trunk space. So if you run out you’re stuck, even after you find a charge station, you’re still stuck until you get a charge. Hopefully that charge station is near a gas station where you can buy bottled municipal water at a 3000% markup. In each of these examples, there are better alternatives. The old ones. Just like the style and vocabulary of before, all the products worked better , lasted longer, and were safer/more healthy.
Would you consider making a video in the future, sharing your thoughts on battery tech in general? what we have now, whats to come in the future and alternatives. Awesome video btw! learned something today :)
Doesn't a 25hp mower only end up with about 8hp of actual power delivered to the cutting blade? With gas engines being so inefficient, wasting the rest in heat? Also you might be mistaken with he efficiency of electric cars being charged by powerplants. The way you put it would mean that a huge powerplant wouldn't be more efficient than your tiny combustion engine (the gas turbine gets to turn at an optimal rpm all the time, compared to gas cars that barely ever run at peak efficiency). Also, why would hybrid cars be more efficient than gas cars then?
I believe engine power is rated at the crankshaft. Wikipedia for example says engine power is, "the product of the engine torque and the crankshaft's angular velocity."
Why do they need to charge overnight? Why can’t you power the car using your own solar? Power your car at less peak times. Use the stored power in the car to feed electric into your house at peak times thus reducing cable size for the network.Etc. a little disingenuous, I believe.
This is becoming more feasible nowadays, but even then you have to factor in the cost/production/materials. I could do exactly as you suggest, but then I'm forking over 10-20k for the whole setup, PLUS the cost of the car, PLUS the cost of a replacement battery pack for the car in 3-5 years - which is unnecessary for a fossil-fuel powered vehicle. It all depends tho. My brother-in-law got solar paid for by the government more or less. Where I am, that's possible but only under certain conditions and up to a certain capacity. And even then, if the government foots the bill, that money comes from somewhere - i.e. it means increased taxes in the long run, so I pay for it anyway. Can't get somethin' for nothin'!
@@ScottiesTech i can’t be certain that the planet or our civilisation will be saved, if the climate predictions are somewhat correct. It very much looks like disaster is coming. We should not wait until everything is perfect before we attempt in the best way we know to go as green as we are able. However, it should not be about a transactional cost benefit as we see it today because, if there is going to be crop failure, wild fires, mass starvation, mass immigration from tropical to temperate zones etc etc, the no matter what the cost, those who can afford to save the planet, either as individuals or countrywide, then the cost benefit, taking all factors into account swings towards going as green as soon as you are able, and the sooner the better.

in cities where people dont have garages i dont think electric cars are possible. even if you provide power , where in terms of space as well as time slots could 1 million cars recharge every day if you need 1/2 hour minimum per car.
I agree with you on almost everything. For the battery powered sidegrinder, you are exchanging usable battery time for the convenience of not being tethered to a power source. As for the lawnmower comparison, most of the battery (and corded) electric lawnmowers are lighter in weight than their gasoline powered counterparts, so they do not need as much power. Same with the internal combustion engine. How efficient is the engine? Maybe 7-17% efficient? How much does the vehicle weigh? But I agree 100% on everything else.
Hybrid(gas + generator + battery) is the way to go until battery tech gets much better, IMHO. Nothing beats the power density and dependiblity of fossil fuels for now.
Spot on mate! Its all very well for society to believe that they are doing the correct thing by switching to battery powered appliances but the hidden cost is the extra mining of minerals, the concentrating of those elements and the extra energy required to manufacture high tech alternatives - LOOK at the BIG picture cost benefit
@@ScottiesTech Hi Scottie, yes lithium is just the start. The increased demand for copper created by more electric demand together with the diverse nature of the alternative generation grid locations is another use that is far from the most efficient use of limited resources. cheers Kevin
Um. You are always entertaining to watch. But... Electric cars are regenerative. So the efficiency is much better than ICE vehicles. Plus, power plant efficiencies are much better than ICE vehicles because the Carnot Cycle temperatures are more extreme at the Power Plant. Plus the pollution capture "may" be better because of the stack scrubbers.
Sure, there are things like regenerative braking. But you need to suck power from the power to accelerate the car in the first place, thereby absorbing power from the battery. When decelerating, even with regenerative braking, you get SOME power back, but not at 100% efficiency. So, it helps, but you're still greatly limited by the battery tech.
Very happy you're willing to speak up about this topic. Green power is when a horse eats grass😁
Good morning Cletus and Scottie! Grabbing my coffee and excited for a new video👍🏻🖖🏻
👍👍👍Thank you

Thanks for the informative video Scottie. Have you heard of Stan Meyer and his water powered car? Very interesting story.

Also let's not go into how much energy is wasted for heat in electric stuff... empty stupid "green" arguments, ugh.
Excellent presentation! Wish a lot our politicians would watch it.
They'll have to "watch it" when the people wise up to their scams.

I like some battery powered garden tools better mostly because of less noise and maintenance.
Very good point about the electrical infrastructure.
