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 ...

If you enjoy being nice to the environment (or if you're just looking to save a few bucks), building a solar heater is a useful weekend project that costs very little, but can heat a good portion of ...

Heat from the solar collectors is distributed through a radiant floor heating system using PEX tubing running through aluminium heat spreader plates. A hot water baseboard heating system is another ...

This home is heated by a wood stove in the winter, which also produces hot water. But the other three seasons it’s an electric water heater that does the work. This latest hack is a solar collector ...

What if you could harness the power of the sun to generate your own energy—right in your backyard? Imagine a system so efficient it could heat water, power small appliances, or even serve as a backup ...

Solar energy is abundant and frustratingly ill-timed. A sunbeam can become either electricity (useful for running modern life) or heat (useful for keeping spaces warm). But conventional solar hardware ...

A newly developed aerogel made mostly of air surrounding a silica structure is so transparent you can barely see it. But it could hold the key to unlocking new applications for solar heating. It traps ...

Solar heat collectors can provide heat for a range of users – homes, offices, industrial processes – and to power cooling systems. Heat can also be stored for later use, while hybrid PVT systems offer ...

A researcher in the Netherlands has developed a new type of hybrid solar collector with a higher efficiency and a longer lifespan than the current hybrid systems. Hybrid solar collectors combine ...
