Low cost, low energy cooling system shows potential

Researchers in the US have scaled up a new low-cost system that could provide efficient cooling for homes while using very little electricity.

The team has developed a roof-top sized array, built from a highly reflective material made from glass and polymers.

In tests, the system kept water around 10C cooler than the ambient air when exposed to midday sunlight in summer.
