As the name implies, the company generates large-scale electric power from hydrogen-storing fuel cells, a technology you've heard plenty about in the context of powering the next generation of cars. The concept is great: Take organic waste materials like chicken droppings and household trash, extract hydrogen gas from said detritus, and use it to power anything from factories to small towns. It works, it's already in production in places like South Korea and California, and FuelCell should make a lot of people very rich ... eventually. My two cents so buy and hold
