Tiny ‘nuclear batteries’ unveiled
Researchers have demonstrated a penny-sized “nuclear battery” that produces energy from the decay of radioisotopes.
As radioactive substances decay, they release charged particles that when properly harvested can create an electrical current.
Nuclear batteries have been in use for military and aerospace applications, but are typically far larger.
The University of Missouri team says that the batteries hold [...]

Dispersed wind farms and solar panels on people’s homes are posing new challenges for managing power grids that were designed when all electricity was generated in centralised plants. A new semantic web technology promises a solution.
Managing increasingly dispersed energy resources – from far-flung wind farms on remote mountaintops to racks of solar panels [...]
