pls, do not be so harsh about battery power. You are right about that:
- It is not meant, to substitute oil at all
- It is not meant, to solve all environmental problems
- It does not reduce costs, at least not right now
It certainly does not mean to overcome physics...
As you mentioned the Chevy Volt, indeed, the cars industries "hottest inventions" seem all to rely on battery power. But it is more, than just that.
Not to be a qualified person for this topic, yet, I have a quite update insights to cars-industries and their view of future:
A big problem, for example, is the drive train. Some sporty, high HP-cars, are struggling against it with forces of nearly 1000Nm force (sorry for the metric: this equals to 2000lbs force?) Where mechanical torque comes to limit, electrical force is nearly unlimited. It also promises, optimal usage of energy, and 50% efficiency is still 50% lost of energy.
-The car industries is learning that, right now.
-They know, Lithium will end sooner than oil.
But they the had to take a chance, and where batteries are no option, maybe a solar produced hydrogen Tank would have been the "Green Guys" ultimate wet dream. You stop at the gas-station, unload your empty tank and snap in a fully charged one within 1min, with zero CO2.
But it will all depend on electric drive-trains, matter or antimatter.
As the cars industries is learning steps, it seems to me RR-industry prospects on "fuel-enhancement" as well. But they have electrical drive-trains already.
- I would be very interesting in results!
- why, the heck, RR let heavy trains run downgrade, using dynamic breaking instead of charging batteries somewhere?
