Once again the box o' rock failed to attach the linkySorry I don't know whatcha talking about?
A sanctimonious dwarf in Ottawa has been watching this Utube.I'm shocked that big energy companies allowed us to see this. Scale that baby up and the world is saved, free power for everybody.
When I think about an internal combustion engine, I still marvel that it was ever mass produced or the fact that they are still in use in such huge numbers, especially when compared to the elegance and simplicity of an electric motor. Obviously the amount of energy in a litre of gas has a lot to do with it.
With the umpteen speed transmissions, VVT etc. etc. I think they have rung about as much as they can out of an inherently inefficient design and for city commuters makes little sense at this point. I'm really looking forward to an electric car for city use, 95% of the time my trips are < 20km.
When I went to school back in 1965, my guidance counsellor was supposed to guide me in choosing a career. I was in the program they looked down on, called vocational, now STEM.When I think about an internal combustion engine, I still marvel that it was ever mass produced or the fact that they are still in use in such huge numbers, especially when compared to the elegance and simplicity of an electric motor.

Probably not a great time to purchase a Midas or rad shop;-)
Having been soaked in the red paint all teachers use, he violently opposed this, and proved to me that in 10 years there would be no oil, and there would be no cars because of this.
I have been trying to figure out, visualize, a 400 hp. tractor, doing field work, (lots of them around here, but pick any hp.) So if this unit is 400 hp., (electric) we would need a 300 kilowatt generator to power it. (Not figureing losses).
The Science of Fear might be the Audible format?Read "RISK - The Science and Politics of Fear" by Dan Gardner.
It sits on the shelf beside the 100mpg carb. lolAll the free power you need from a self running car alternator.
I just re-read 1984 and sickening as it is, I realized what a clear vision of the future he had.I just downloaded Animal Farm for old times sake. Sadly, despite being written in the 1940s, you can still identify the characters in whatever decade you are in. A rather sad testament to humanity.
See link. Solid state research has been ongoing for some time. They do have promise in certain areas like improved charge rate which is another major e-handicap. But as if this writing I don't think the numbers go round. 400 WH/kg = 1.42 MJ/kg = 2.8% the energy density of common hydrocarbon fuels. Even if they double the current performance it would be only 5% of HC. You can direct translate that percent into how long big machines will run (under optimal conditions).Battery tech is entering the stage of solid state that in theory will run the big machines, trucks and tractors all day without recharging and will recharge in time to use them again as needed.
Even with the latest batteries, liquid fuels store 75x more energy per unit of weight. So it's not just a little amount of energy difference. Factor in that horrible IC combustion efficiency and your still at 35:1. Gasoline is the energy density king of the hill at 50 MJ/kg or 35MJ/L. The best batteries of today are only 350 Wh/kg and state of the art is double that but not yet commercialized. For comparison, 350Wh = 1.25 MJ
Ah. What everyone is missing on this topic is what's not being said, or what's being said but couched in the finest, smoothest, purest BS money can buy, is that the a$$hats promoting this garbage don't want everyone to have an EV (or tractor, or freight truck) that's allowed to operate at your will. They want to get everyone hooked on 'em, then dictate when/where you can charge/drive. Gasoline & diesel represent uncontrollable freedom.I have been trying to figure out, visualize, a 400 hp. tractor, doing field work...
