Here’s a way to make environmental cleanup more fun: Next time you’ve got a polluted waterway, just unleash a swarm of tiny, bacteria-nomming robots on it.
We've known for over a century that bacteria can generate electricity. But now, we can put that knowledge to use and turn each toilet flush into a potential source of energy.
Microbial fuel cells are notoriously inefficient. Electrodialysis systems are notoriously expensive. However if you combine the two and add some poo, they can turn waste water into a viable power source. The future of green energy is brown.
All those fly-catchers—the sticky ones, the glowing ones, the zappy ones—seem like such a waste. Surely there's something to do with all those fly carcasses, aside from cringing at them. Enter James Auger and Jimmy Loizeau—insect nemeses.
