[AB] MIT Develops Liquid Fuel For Electric Cars. - Page 2

post #11 of 43
I wonder how reliable the pump inside the battery is? I imagine it's a harsh environment, both in terms of corrosivness and friction from pumping granulated solids suspended in a liquid.

this would make them 690mpg
I don't think any oil based fuel using car matches that at the moment.

Remember: This technology is still in it's infancy, and that even in it's infancy is 10 times more efficient than current battery technology.

Also remember that high-bypass turbofans are the most efficient way to propel aircraft at that altitude using today's fuel. I always feel that people make the assumption that the best now is the best forever.

However, I do think that nothing will change in the very near future, in terms of high altitude aviation. I could see this technology being very useful to commuter turboprops as well as the Cessna's you speak of, particularly with AVGas prices going where they're going.

I also like cars with gears. If these electric cars take off, give me an H-box and I'll drive the piss out of it. On-demand torque? Win.

But alas, ryboto sounds like he has a point...

meh. Hydrogen is where its at.
No idea why no one has made an internal combustion engine that runs on hydrogen, not a fuel cell - a proper engine.

why would you combust hydrogen and waste the energy? the hydrogen has to be gotten from crude oil in the first place, that requires a lot of energy itself, to then waste it would be worse for the environment than engines are now!
you don't get much more efficient (90%) than converting straight to energy.

Not really my point, but ok.

Not sure if trolling.

Hydrogen can be gotten from electrolysis or whatever using electricity to split water is called.
Combusting hydrogen wouldn't be wasting the energy, we've been doing it for years (petrol) but with carbon aswell.

I was about to say the same. Hydrogen is plentiful, and does not require Oil to produce. Thanks for clarification. Hmm I wonder where all those Water based combustion patents went...
