A group of scientists at the University of Cordoba, in Spain, has developed a photovoltaic system design for hot water production that is claimed to use around 95% of the available energy it can ...

Q: Based on our water bills, my family uses lots of water and much of it is probably hot water. Is there a simple solar hot water system design that I could build myself? A: Heating water can account ...

With the aid of nanotech materials, scientists have engineered a new way to convert the sun's heat into electricity that is roughly eight times more efficient than previously reported solar ...

The system is described by its creators as a cost-effective solution for water heating by storing thermal energy in fine sand. Techno-economic analysis indicated the system is economically viable for ...

A saving of around £150 per year would give us a payback period of around 26 years on the capital cost of installing a solar ...

Installing solar power at a home is a great way to reduce electricity bills, especially as the cost of solar panels and their associated electronics continue to plummet. Not every utility allows ...

Desalination is being explored as a way to solve the shortages of drinking water that plague much of the world, but it has a few issues to iron out. A new design for a solar-powered desalination ...
