It is amazing the lengths that people will go to in order to make biofuels work. I think the sun->wheels efficiency will have a hard time exceeding 1/2% when you factor in photosynthesis, biomass transportation and the combustion engine.

A solar panel combined with an electric motor is around 16% efficient today. We just need to figure out how to deliver electricity to moving vehicles. Some combination of overhead wires or guideways can serve most commuters and cargo without destroying our food supply.

Eh.... The smoke and mirrored policies rarely effect any shadow of common sense- they just tend to pretense. It all becomes temporarily offset with thee ever greater/ongoing subjected clause of morewardumbery fiat nonsense solutions. The laws of physics and thermo do not require any stated energy source--we never really quite get back what we put in do we? Ah, we have a glorious mountain of mammonized waste that can be bilked if and when nesessary invokes stretch marks. That is when eyelids and pupils adjust - and when individual I's and institutionalized Q's pop. That is when reality moves beyond thee bullchit consumerism vanity of making it to break to sell more. We have a big fat sofa of relaxation to extract our previously broken wasted ways from. Won't that be comforting inbetween the tracer rounds?

Food supply will become more local, and this is because it has little choice/options. Things will be in season because half way around thee world will require sum importance beyond a squid appetizer.

Even when we are destructing foreign lands for booty of liquid black energy, this simple equation does/will not change.

Moving vehicles and electricty are not a big problem when the obvious waste is eliminated and the power is/becomes slightly sustainably generated....atleast not a problem in an environment with leaders that have sum thinking semblance of an actual forthcoming clue.
