The beat of the feet

Here the Guardian reports that movements by people, including their heartbeats, can create power. (In the case of the heartbeat this could be used to power pacemakers, removing the need for regular battery-replacement operations - hmm - but the pacemaker is there to stimulate/manage the heartbeats?).

Makes me wonder about creating powercells to harvest the power created in concert halls. Presumably acoustic vibrations could also be converted into power? You could then link it to the hall's lighting system and the light might go up in the Symphonie Fantastique and shrink in Bach's solo cello suites (no-one performs those from sheet music anyway).

Then in the Vilnius Filharmonia you could place power harvesting cells under the seats - people are noisily shuffling their feet all the time. In the place where people meander during the interval, under the entrance doors and the doors into the toilets (as they already do in old people's homes where sensors check if they are moving about (and thus alive)). Never mind the conductor's rostrum, into the timps (so they could tastefully light up from the inside....). You could place tiny cells into the right-arm sleeves of string players, windblown generators into brass instruments....

People using keyboards (roughly the whole world, counting computer keyboards) could use gloves with sensors....

I recently came across your blog and have been reading along. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.
