Continuing the parade of things that you can't actually get yet: As they say: "Small, cheap, and good: pick two."
But no! Or so says the University of Houston, who have claimed to developed a small, cheap, and good fuel cell using thin film solid oxides.
Small: a fuel cell with the volume of four sugar cubes can power a laptop computer; one the size of two soda cans can power a house.
Cheap: does not use the ultra-pure and exotic materials of standard fuel cells.
Good: thin film solid oxides have a 60-70% efficiency, and run at half the temperature of normal solid oxide fuel cells, at a mere 450 to 500 degrees Celsius.
Wow! I can't wait to put a tiny 500 C battery in my lap.
