Researchers Spray-Paint Batteries Onto Almost Any Surface
Warmlight writes "Rice University researchers have created a type of lithium-ion battery that can be spray-painted onto most surfaces. 'Their batteries, outlined in Scientific Reports (abstract), are made up of five separate layers, each with its own recipe — together measuring just 0.5mm thick. To demonstrate the technique, the team painted batteries onto steel, glass, ceramic tile and even a beer stein.' What do you think this will do for future form-factors? Maybe a form-fitting PipBoy-style device that doesn't weigh 30lbs?"
There are two very important questions that should have been answered:
1) How much power are the getting from the Beer Stein in the picture.
2) What beer is in the stein.

In another twenty years expect batteries formed from pure thought.
Least reliable power source ever.

I'd just be happy with a battery that 1/2 to 1/10 of the energy volume density of gasoline
Ever raise kids?
No...how do they compare to gasoline for energy density?
