Cool New Fuel Cells
Researchers at the University of Houston have developed smaller, more efficient thin film solid oxide fuel cells (SOFCs). A cell about the size of four sugar cubes would produce enough energy to power a laptop and one the size of 2 beer cans could power a house. One limitation still to be worked out before we start popping these SOFCs in our phones and laptops is that they have an operating temperature of 500 degrees Celsius.
