What has the Shogun been saying about turning Deserts into proverbial batteries, kiddies?
Saharan sun to power European supergrid

Vast farms of solar panels in the Sahara desert could provide clean electricity for the whole of Europe, according to EU scientists working on a plan to pool the region's renewable energy.
Harnessing the power of the desert sun is at the centre of ambitious scheme to build a €45bn (£35.7bn) European supergrid that would allow countries across the continent to share electricity from abundant green sources such as wind energy in the UK and Denmark and geothermal energy from Iceland and Italy.
The idea is gaining growing political support in Europe with both Gordon Brown and Nicholas Sarkozy recently giving backing to the north African solar plan.
Speaking today at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% of the light falling on the Sahara and Middle Eastern deserts to provide all of Europe's energy needs.
In addition, because the sunlight in this area is more intense, solar photovoltaic (PV) panels in northern Africa could generate up to three times the electricity compared with similar panels in northern Europe.
Jaeger-Walden explained how electricity produced in solar farms in Africa, each containing power plants generating around 50-200MW of power, could be fed thousands of miles across European countries by using high-voltage direct current transmission lines instead of the traditional alternating current lines. Energy losses on DC lines are far lower than AC ones where transmission of energy over long distances is uneconomic.
"If you look at solar radiation, then the Mediterranean region is a very favourable one," said Jaeger-Walden.
He said that the proposed grid was a way to balance out the intermittencies of renewable energy: "If you can connect the grid to hydro power, you've got that as a backup battery, and in addition there's wind. It's not a single source that's providing the energy but a combination of the different renewable energies."
Conveniently the potential to generate solar energy, either from photovoltaic cells, or by using it to heat water, is at its highest exactly when there is peak demand. "Between 11am and 1pm – there are a lot of cooking activities going on, people are going home, air conditioners are used," he said.
The idea of developing solar farms in the Mediterranean region and north Africa was given a boost recently by French president Nicholas Sarkozy earlier this month when he highlighted solar farms in north Africa as a key part of the work of his newly-formed Mediterranean Union.
I swear to god. Im like a local fucking Arthur C Clarke.
