Click For Summary
The discussion highlights the complexities surrounding hydrogen cars and their environmental impact compared to battery electric vehicles. While hydrogen fuel cells produce no direct emissions, the production of hydrogen often relies on fossil fuels, potentially negating their pollution benefits. Hydrogen is viewed as an energy carrier that could utilize renewable sources, but significant challenges remain in its storage, distribution, and production efficiency. Batteries currently have a more established infrastructure and better overall efficiency, although they also face issues like weight and disposal concerns. Ultimately, both technologies require further development and innovation to address their respective limitations and achieve a sustainable transportation future.

I read about a study (don't have any internet source handy, it was cited in a book) that says that hybrid electric cars are a near-future possibility, as many car trips are relatively short distance. So relatively small batteries, charged at night, could replace the short distance displacements (commuting to work for instance), while the classical fuel engine would take over for longer trips. This limits the need for huge batteries, while nevertheless allowing most car traffic to run on electricity. An average of 2 liters / 100 km was a conservative estimate of the consumption of such a car.
Yes that is certainly the plan for, say, the Chevy Volt - ~30-40mi per charge on the batteries w/ an engine for the long haul. That is the plan for numerous, high volume sales plug-ins coming out. Its not just a possibility, these plug-ins are definitely coming out in the ~2010 model year. So 100% of commute driving becomes all electric, zero emissions at the car. That is the reasoning behind the large reductions in oil imports and CO2 mentioned in the above WSJ links.

Several new startup electric car companies in play

There are at several new/startup electric or hybrid electric plug-in car companies bringing out models between now an 2010. Many of the founders come from big car companies. These companies are going up against the competition from the models forthcoming from the large competitors Toyota, Ford, GM, Mitsubishi, Renault, and Daimler. The new car companies:

Tesla: sport all electric, 221mi range, out now

Fisker: sport hybrid 50mi electric, ICE backup, 2009

Think: all electric small commuter, 112 mi, 2008 (been around since '91 as Pivco)

Loremo: diesel hybrid 93mi electric, 600mi ICE, 2010

Mindset: hybrid, 62 mi electric, 498mi ICE, 2009

Gordon Murray Design: the McLaren UK race designer w/ experience in carbon fiber frame& body. 892 lbs lighter than other similar metal cars.
