Alternative power sources are able to do more than just save the
planet. Now, they can help save people, too. Spectra
Watermakers, Inc. of San Rafael, Calif. has introduced the new
Solar Cube, a portable water treatment machine powered by solar
and wind that can provide clean drinking water in disaster
situations. Powered by 24-volt batteries, which are charged by
integrated photovoltaic panels and a wind-powered generator on
the machine, the Solar Cube is portable and easily assembled on-
site in less than an hour. By placing a pump, which is also
attached to the machine, into a polluted or saltwater source,
the Solar Cube captures the water and pumps it through a series
of filters, including a reverse osmosis membrane in the final
stage, which eliminates microscopic bacteria, viruses, salts and
dangerous chemicals. The Solar Cube can provide up to 3,500
gallons of clean drinking water a day, enough to sustain
hundreds of families during a disaster. It can provide enough
energy to power other vital emergency
