This High Concentration Photovoltaic Thermal System (HCPVT) can harness the energy of 2,000 suns and provide fresh water and air conditioning in remote locations. The prototype HCPVT system under development uses a large parabolic dish, made from a multitude of mirror facets, which is attached to a tracking system that determines the best angle based on the position of the sun. Once aligned, the sun’s rays reflect off the mirror onto several microchannel-liquid cooled receivers with triple junction photovoltaic chips — each 1x1 centimeter chip can convert 200-250 watts, on average, over a typical eight hour day in a sunny region.

If Earth’s water were drained into a single drop, it would measure about 950 miles in diameter. Roughly three percent is fresh water, and just one-third of that is easily accessible. Meeting the growing need for water is a critical challenge. Many countries rely on desalination to produce fresh water, but current techniques are typically energy-intensive, using enough energy globally to power nearly seven million homes. That’s why today GE is launching an open innovation challenge to improve the energy efficiency of water desalination. Find out more about the challenge here.

An Energy Upgrade On a Budget

Subtitle: 

A homeowner has to choose among recommendations from an energy audit: More insulation, new windows, or an air-source heat pump?

Christian Rodriguez has taken an important first step in improving the energy efficiency and comfort of his 1880s home by arranging for an energy auditEnergy audit that also includes inspections and tests to assess moisture flow, combustion safety, thermal comfort, indoor air quality, and durability.. With the results in hand, his first step was to air-seal the attic and add 20 inches of cellulose insulationThermal insulation made from recycled newspaper or other wastepaper; often treated with borates for fire and insect protection..

"This made quite a difference both in comfort and heating bills," he writes in a Q&A post at Green Building Advisor. Now comes a difficult decision: what to do next.
