Time to give up on alternative fuels and electric cars saving us. Public transit and rail are proven solutions that many countries around the world are heavily investing in, including China, India and even oil-rich gulf states. Time the US stops wasting money on highways and roads and instead builds high-speed rail and urban rapid transit.

  For 500 million.  Make it from algae in solar colectors on the roof and mass produce the systems  too, with that kind of cash!  It really is carbon neutral that way.  They gave the 500 million to the wrong team though.

All they will get is years of studies, but that's what they really want, isn't it?  A diversion to keep the gas guzzling going.

The 500 million and roof space is better spent on solarPV/heat cogeneration.  38% efficient at 10 suns in solar concentrators.  

Even algae grown in solar concentrators converted to ethanol would be under 10%.  Then there is the much greater expense and complexity of algae/ethanol over solar PV concentrators.

And the very low efficency of internal combustion of ethanol (6% to the wheels)versus plugin renewable electric powered vehicles.

More than 10 times the solar energy collection area would be needed with algae/ethanol than with solar PV to drive the same number of miles.

There is enough roof space to power our homes and plugin cars with solar PV/heat cogeneration.  Why waste it growing fuel?

That's what this really is, right? We gotta keep corn ethanol going because it's making our campaign contributors rich, but the logic of it is failing consistently. So we point to cellulosic ethanol as the savior of the future, keep claiming that corn ethanol is just a bridge to the real thing, and also keep the infrastructure locked on internal-combustion, liquid-fuel vehicles to keep the oil lobby happy. Works good for the big lobbies and Congress, really the only downside is that it's delaying solutions to global warming until it's too late. Which will only affect those pathetically weak entities, animals, which need to breathe and eat and so on.
