My point is that if theyre packed in tightly it would inhibit them from bouncing around. "Room to move" may have been a better description. |

You'd get more energy by burning the beans. On the other hand, a quick calculation/guess based on 5 g beans jumping 1 centimetre every 2 seconds suggests you'd need about 4 million of them to run a 1 kW electric kettle, assuming your piezoelectric doohickies can convert all their kinetic energy to electricity. |

Very generous [krop]! That practically doubles the awesome power I came up with. |

Piezoelectric materials are great at generating voltages; they're horrible at producing current. |

That's odd. You can't just hook up some wires and let Ohm do his dirty work? |

Actually my solar panel put out 8v ac when exposed to a constant noise. Implying that the solar cell does exhibit some piezo electric conversion of energy from a normal 4.5v DC solar panel. |
