Startup GMZ Energy raises $14 million to make materials that convert heat to electricity, including a solar hot thermal product and chips to draw electricity from car exhaust pipes. Martin LaMonica is ...

David Kuchta, Ph.D. has 10 years of experience in gardening and has read widely in environmental history and the energy transition. An environmental activist since the 1970s, he is also a historian, ...

at the headquarters of ubiquitous energy near SAn Francisco, the familiar black solar panels on the roof are pretty obvious, but the lights in the company conference room are being powered by the ...

We may hear a lot about photovoltaic panels, but solar collectors are also quite useful – the devices collect heat from sunlight, which is used in applications such as the heating of homes. Now, MIT ...

With more people installing solar panels at home, a new company develops monitoring device and app that keeps tabs on electricity or hot water production. Martin LaMonica is a senior writer covering ...

This circuit optimises the operation of a solar hot water system. When the water in the solar collector is hotter than the storage tank, the pump runs. The circuit comprises two LM335Z temperature ...

Parabolic trough solar collectors (PTCs) remain at the forefront of concentrated solar power technologies, converting solar irradiance into high-grade thermal energy through a curved reflective ...

Nanotechnology mimics plant photropism to provide efficient solar energy collection. Imagine your roof covered in tiny sunflower-like solar collectors that provide all the energy you need to run your ...

A new kind of solar technology has set a world record for the most efficient generation of energy by a solar cell. By stacking six different photoactive layers, the record-setting multi-junction cell ...

Is space-based solar power a costly, risky pipe dream? Or is it a viable way to combat climate change? Although beaming solar power from space to Earth could ultimately involve transmitting gigawatts, ...
