Yea I watched that a few months back, good stuff. Too bad there's only a few prototypes, they are smaller than a HMMWV, and the cost is exorbitant. I do think that to some degree, hydrogen fuel cells will play large roll in our power cells on a small household or individual basis in the future, but like most impressive technologies in use by governments and multi-billion dollar corporations, the cost is just beyond mass production and affordability of the common man at this moment in time. That said, the technology is impressive and it is certainly something worth continuing to develop.
