Most of us think of solar energy as consisting of photovoltaic solar panels, which make up 95 percent of the solar energy market. Solar towers, however, are proving to be a promising technology for commercial-scale installations as well.
Construction is now underway on the Ashalim Thermal Solar Power Station, where a vacant stretch of the Negev desert in Israel will be home to a 787-foot solar tower.
This is a big step in achieving Israel’s goal to source 10 percent of its energy from renewables by 2020. The solar tower will produce enough electricity to power 121,000 Israeli homes, or meet 1 percent of Israel’s total electricity needs. Although the project is privately funded, the Israeli government has agreed to buy the power at above-market prices. Construction is expected to conclude late next year.

Inspired by the concept of making a sustainable lifestyle easier, GreenPod creates low-maintenance modular homes with healthy interiors.
Factory-built kits can be transported to a building site and easily assembled. Using state-of-the-art technology and materials, these homes have a small footprint and conserve both water and energy. The homes, including tree houses and floating homes, are customized to the site, have passive solar features and minimize site disturbance.
The walls, floor and roof of the homes use SIPs (Structurally Insulated Panels), with a rain shield on the exterior. “The homes are precut when they come out of the factory, so they can go up in a day or two on the site,” says Ann Raab, GreenPod’s founder. “SIPs are the best bang for your buck. Although they are slightly more expensive than a stick built home, SIPS have a short 2.7-year payback. They are stronger and straighter than wood, with no job waste [because the SIPs are precut]. Everything about SIPs delivers what we are trying to create.”
Raab has a vision to simplify green building, while making sustainable living affordable for the mainstream. GreenPod homes are customized to fit a variety of budgets, with optional features including: locally-crated furniture containing organic textiles, reclaimed building materials, solar panels and a biofilter refrigerator.
