Your average hydrogen-powered car is a marvel of modern science -- fuel cell sifting electrons out of pure H2 and emitting nothing but water -- powered by big, heavy, high-pressure tanks of gas. Cella Energy is here to ditch the tank, having first developed a means of storing hydrogen in microfibers that could greatly simplify the design of these vehicles. But, perhaps even more impressive is a "synthetic fuel" the company is working on which is, essentially, pure hydrogen captured into microbeads. You know, like the kind that float in your sham
