Biofuel cells may turn cockroaches into cyborgs

The sugars in a cockroach’s belly have been harnessed by a fuel cell and converted into electricity, a big step toward turning insects into cyborgs, scientists are reporting.

Once miniaturized to the point that the fuel cells are non-invasive to the cockroaches, they can be implanted to power sensors or recording devices, for example.

Poop fuels hydrogen cars

An experimental fuel cell at a wastewater treatment plant in California is turning poop flushed down the drain into hydrogen fuel for cars.

The novel fuel cell converts biogas — methane — produced in digesters at the plant into heat, electricity and hydrogen. The heat is fed back to the digesters, the electricity powers the plant, and the hydrogen is fuel for cars.
