The Solar Cube is a cooperative project by Spectra Watermakers and Trunz Metallchnik AG of Switzerland. Currently in use in isolated villages in Venezuela and Pakistan, the unit is portable and easily assembled onsite. It’s powered by 24vt batteries charged by integrated photovoltaic solar panels and a wind-powered generator, providing up to 3500gpd of clean drinking water from polluted or salt water. Water is pumped through a series of filters to remove large matter, with RO as a final stage for reduction of bacteria, viruses, salts and chemicals. It can also provide enough energy for emergency disaster officials to power refrigeration for emergency medical supplies, keep a laptop on-line, or ensure that crisis communications equipment remains operational.
