Geez...who the hell thinks up this stuff??
Power generating capacity is defined by the amount of Watts something can generate. Voltage is only half of the equation. P= V * I (where I = current in Amps).Eddie_42 said:
It would also be important to note the power capacity. a few micro volts? maybe even a whole volt?
I know the it says you can fit "up to 100 PZT strips can fit in a millimeter of space", so even if they don't put out a lot of power they don't take up much space. But how many would you need to say keep your cell phone charged? Or an MP3 player charged?Puiu said:
I want numbers. Can it really power a phone just by walking a few steps or do we need to jog kilometers just to talk for a minute.
