The sun’s energy can be captured by homemade solar hot-air collectors and thermosiphoning panels to provide free heat. The units direct air warmed by the sun through a window or wall opening into the ...

Solar space heating is tricky. Air is harder to keep warm than water, and while most of us need a shower on a hot day—we tend to want space heating when the sun is not doing enough for us.

A couple of years ago we heard about the MOlecular Solar Thermal (MOST) system, in which solar energy is stored in a liquid medium, then later released as heat. Now, the technology has been applied to ...

It took a while to decode the email I received from Carroll Hampleman (you can see why below), but his home made water heater is worth the bother. Mirrors are arranged to reflect and concentrate the ...

A new technique has been developed for capturing solar power through windows, which could dramatically improve solar energy utilization, particularly for high-rise buildings.

Transparent new solar technology offers novel ways to use electricity around your home and could automate new and existing window functions. But your windows are still just glass panes in a frame.

Our team tests, rates, and reviews more than 1,500 products each year to help you make better buying decisions and get more from technology. Tapping into solar energy at home currently means having ...

A British firm wins over $150,000 to begin commercializing its technology, which screen-prints organic solar cells directly onto windowpanes. An Oxford University-affiliated group has won over ...
