Science Is Fun Home Experiments. Torresol Energy - Gemasolar thermosolar plant. Gemasolar is the first commercial-scale plant in the world to apply central tower receiver and molten salt heat storage technology. The relevance of this plant lies in its technological uniqueness, since it opens up the way for new thermosolar electrical generation technology. Characteristics of Gemasolar: Rated electrical power: 19.9 MWNet electrical production expected: 110 GWh/year Solar field: 2,650 heliostats on 185 hectaresHeat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed. The prolongation of the plant's operating time in the absence of solar radiation and the improvement in efficiency of the use of the heat from the sun makes Gemasolar's output much higher than that which is delivered by other technologies in a facility with the same power.
The notable increase in the plant's power efficiency guarantees electrical production for 6,500 hours a year, 1.5 to 3 times more than other renewable energies. How A Young Physicist Is Making Solar Power Work, Even When The Sun Is Down. It is not unreasonable to expect that the renewable energy collected by the world’s solar panels and wind farms is being stored somewhere, ready and waiting to power our microwaves and hairdryers at a moment’s notice.
Bad news: mostly, it’s not. Sure, there are a few methods in practice--expensive batteries that degrade over time, a medieval-sounding technique that involves pumping water up and down a hill--but by and large, if there’s a lot of wind blowing but not enough lightbulbs to use it, that energy simply goes to waste. Hopefully, that’s about to change. Danielle Fong is the chief scientist (and grade-school dropout) behind LightSail Energy, a Berkeley-based team that’s developing compressed-air technology to store the power we don’t use, and return it to the grid when needed. Compressed-air technology has long struggled with efficiency--the heat energy generated via compression has always gone to waste--and that’s the almost part where LightSail’s greatest innovation swoops in. Scientists Confirm There is a Second, Secret DNA Code That Controls Genes. 7th January 2014 By Michael Forrester Guest Writer for Wake Up World The fascinating and recent discovery of a new, second DNA code further lends credence to what metaphysical scientists have been saying for millennia — the body speaks two different languages.
Since the genetic code was deciphered in the 1960s, researchers have assumed that it was used exclusively to write information about proteins. No Such Thing As Junk DNA The human genome is packed with at least four million gene switches that reside in bits of DNA that once were dismissed as “junk”. As scientists delved into the “junk” — parts of the DNA that are not actual genes containing instructions for proteins — they discovered a complex system that controls genes.
[For more information, see: 97 Percent of Our DNA Has a Higher Purpose And Is Not ‘Junk’ As Labeled By Scientists] The genetic code uses a 64-letter alphabet called codons. DNA Code Controls Genes These two meanings seem to have evolved in concert with each other.
