I drove 1800 miles in a Hydrogen Car

I helped design a hydrogen fueling station when I worked at Parsons in 2008. I knew absolutely nothing about them but the government gave us a contract and I got assigned to it. I guess they thought I was good with numbers. So I googled it on my first day working on the assignment. What I found out was. A. The government has been working on PEM cells for decades. They don't last. They are not 100% efficient. We were putting hydrogen in 5000 PSIG tanks. Hydrogen leaking is or was a big thing in 2008. It's not potable like gasoline. You can't pipe it. Keep in mind that hydrogen is NOT a source of energy. It is an energy carrier. I think you covered that well. It takes more energy to make it than it contains. Lots more. Gasoline on the other hand has an amazing 120,000 BTUs per gallons and I love the sound of a plat plane crank at 8500 rpms. 

I was turned off when the Toyota spokesperson you were talking to said we are destroying our plant. What? 

How?

The CO2 GH effect is logarithmic and most of function is compete at just 20 ppm. The spectrum is saturated. Look that up. Also.
