Detecting risky residual currents using differential current measurement: operating electrical systems safely with RC monitoring
Residual currents in low voltage networks represent a fundamental safety risk, if they go undetected or if they are detected too late. They may cause operations to be interrupted unexpectedly, incurring damage to man and machine and in the final instance, leading to high costs. "Detect early, warn and take action" are the watchwords in risk prevention. Permanent monitoring of residual currents is ...

Idea could lead to cheap solar cells using plant waste
Remote communities could eventually make their own solar cells using waste vegetation, thanks to a design developed by researchers in Switzerland and the United States. The technology is inspired by photosynthesis. In plant cells, sunlight separates electrical charges with almost 100 per cent efficiency. Electrical charges must also be separated to create currents in solar cells. For the past ...

Solar Paint and Other Solar Surprises
Solar paint - just paint it on your wall, car, boat - and you can start generating electricity. Chemical engineer Cyrus Wadia says, 'Today this is science fiction; but everything we do is moving us toward that. A doctoral student with UC Berkeley's interdisciplinary Energy and Resources Group, Wadia came back to school after six years in business. He spends long hours in the lab 'synthesizing ...
