- ryanblakeley 3y ago> generated 68x more power than needed to operate its sensors > all components...can be purchased at a local hardware store I can't help but think this would be used for surveillance. All you need is dirt to run a sensor and transmitter. But it's cool science. It would be interesting to figure out how much does it take away from the soil biome's energy budget. If you did a whole acre of these, would the insects, worms, and millipedes take a hit, and then birds and reptiles etc.?
- happyopossum 3y agoA single acre of anything isn’t really enough to affect upper level life forms - birds, lizards, heck - even insects can move a few hundred feet that-a-way and get back to doing what they do.
- Metacelsus 3y agoWe made one of these in my college microbiology class! It could blink a red LED. Many kinds of soil bacteria aren't very picky about their choice of electron acceptor. They're "breathing" using wires instead of oxygen.
