According to IBM, the HCPVT is built from unusually low-cost materials, meaning the per area price of setting it up is significantly lower than comparable solar systems, as is the cost per kilowatt hour....
Just one square meter of receiver area in the HCPVT system can provide 30 to 40 liters of drinkable water per day — about half the needed daily amount for the average person, according to the United Nations. The researchers think a large array of the dishes could produce enough fresh water to sustain a town. On top of that, the system can even provide air conditioning, using an absorption chiller rather than the standard compression chiller...
The long-term vision is to build arrays in areas of southern Europe, Africa, the Arabic Peninsula, South America, Australia, and the southwestern United States — places that are remote, dry, and in need of both affordable sustainable energy and greater supplies of drinking water.Climate Progress
Two-For-One: A New Solar Dish Delivers Low-Cost Electricity Along With Fresh Water

ReplyDeleteThat seems a bit high...
rsp,
I don't have the figures in front of me, but it probably includes cooking, cleaning, toilet, etc. There is also quite a bit of waste. One doesn't realize the amount of waste until one lives in a water restricted area and experiences how much one actually needs to use.
ReplyDeleteElectricity plus water! Sounds very promising.
ReplyDeleteHow about harnessing the earth's electro magnetic field for a source of energy? If you are familiar with how an electric motor works, picture and array of satellites positioned in a spiral pattern around the earth from the north pole to the south pole. The satellites would be connected by way of an electron beam so that the spiral configuration would be connected from one satellite to the other and then back down to earth at a receiving station which receives the electron beam. The rotation of the earth and its electro magnetic field would intersect with the electron beam satellite spiral and generate a flow of electrons which could be captured at the receiving stations.
