Sridhar with fuel cell

What goes into the fuel cell? Sridhar asks. Traditional fuel, natural gas, renewable fuel. Biomass gas, landfill gas, ethanol. Whatever you have, he says.

Sridhar says that to change a fuel, people can just begin pumping it into the unit. It will then automatically figure out what's going into it and keep working.

Seen here, Sridhar holds one of the finished fuel cells that goes into the Bloom box stack.
