On the battery thread, check this out! If they use the same space that we already have for batteries in our laptops, wow!!!!
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.
