The traditional Finnish sauna is a water/energy phenomenon. By using wood (traditionally) or rocks to heat volcanic rocks, water can be splashed on the rocks to create steam. This steam is naturally circulated around the sauna, especially if you’re fortunate enough to be in a barrel sauna. The sauna is the perfect representation of heat/energy and water. When in a …

The historic cost declines of solar panels make Photovoltaic Domestic Water Heating an attractive possibility for widespread domestic water heating. As far back as 2012, Mark Holladay of Green Building Advisors predicted the decline of flat plate and vacuum tube solar collectors. Now, thousands of homeowners in Nevada could find heating large, well-insulated water tanks can ensure their solar panels maintain value. Solar thermal …

LARGE, INFLEXIBLE DESALINATION PLANTS COULD JEOPARDIZE CALIFORNIA’S RENEWABLE ENERGY TARGETS AND INCREASE THE COST OF BOTH WATER AND ENERGY. BETTER DESIGNED DESALINATION PLANTS CAN BE A GRID RESOURCE ENABLING RENEWABLE MICROGRIDS. Maintaining a balance on the electric grid used to be simple for utilities, just follow demand with turbine generators. The electric utilities had a monopoly on generation and were incentivized to build plenty of infrastructure, so there was more than …

Water and Energy are the two most basic and important aspects of off grid living. Since 2001, Sisyan has shown that Solar Photovoltaics and Reverse Osmosis Desalination can make for a reliable, efficient source of energy and water. Until recently, the lead acid batteries required to produce water around the clock have accounted for over 60% of the cost of …

Desalination Will Be Necessary A 40% gap between freshwater supply and demand is predicted by 2030, and the stress on natural water systems can be seen now in every part of the world. In addition to all methods of water recycling and conservation, new sources will be necessary. Seawater is the only sources that is drought-proof and virtually inexhaustible. Unfortunately, …
