Hydrogen is a great example of using a 100 penny nail when a 10 penny nail will do. The money needs to be put into electric and hybrid cars. My Prius works great and is affordable. Who in their right mind is going to spend $40,000-$60,000 to drive to the grocery store or to work in a hydrogen fuel cell car when they can get an affordable hybrid or electric car? Some do anyway but they are wealthy and can afford it. Most can't. Put the effort where it will do the most good in getting affordable vehicles to the most people, so we can get rid of foreign oil. We need to start drilling for more oil of our own. The Chinese are planning on drilling in our own Gulf so why aren't we. We can solve this problem if only our politicians would get out of bed with the environmental wackos!
