Interesting article from New Science describing how a "coronal mass ejection" from the Sun could melt down the electrical power gird. ".... Over the last few decades, western civilisations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences..." The article does offer a solution: upgrade the ACE solar satellite, to detect an electro magnetic surge and provide power grid operators with about 15 minutes to shut down their systems. The article does not discuss another possible option: stop building centralized power sources that demand increasingly massive power grids. Instead, concentrate on meeting energy needs using localized sources of power; like the highly portable Hyperion Power Module.

The Times has a story in the "deserts of gold" genre, confusing solar PV (panels) with concentrating solar thermal power - Solar panels in the Sahara 'could power the whole of Europe'. There is a new twist to the story now though, with North Africa's wind power potential also being touted. All of Europe's energy needs could be supplied by building an array of solar panels in the Sahara, the climate change conference has been told. Technological advances combined with falling costs have made it realistic to consider North Africa as Europe's main source of imported energy. By harnessing the power of the Sun, possibly in tandem with wind farms along the North African coastline, Europe could easily meet its 2020 target of generating at least 20 per cent of its energy from renewable sources.

We already know that concentrated solar power (CSP) is shaking things up in the solar industry. A subset within the industry is turning up the heat. "Extreme" Concentrated solar magnifies intense sunlight onto a solar cell, at temperatures that could melt it, to boost efficiency for less money.

shared by Colin Bennett on 07 Jan 08 - Cached

Solar power is a truly efficient source of energy, but it tends to fluctuate, and, as you might know, it turns off at night. One clever way to alleviate this intermittence is to store solar energy in the form of heat using molten salt. An aerospace company, Hamilton Sundstra, has created a venture called SolarReserve, and it plans to have its first molten salt solar power plant online by 2010.

They look like foil party balloons, but they are actually very efficient solar concentrators. These solar “balloons” were developed by a company called Cool Earth, based in California, and it has just received $21 million dollars in investor funding. The company is now planning to build a 10-megawatt plant of solar balloons in the next couple years. This power plant would be comprised of 10,000 balloons, and cover roughly 80 acres!

The solar industry is booming. With waves of investment and grants, the solar power industry is for the first time becoming a serious business. New power plants will soon be pumping power out to consumers, while other firms market to sell panels directly to the consumer, providing them with a more direct means of experiencing solar energy.

On a perfect New Mexico winter day — with the sky almost 10 percent brighter than usual — Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25 percent net efficiency rate. The old 1984 record of 29.4 percent was toppled Jan. 31 on SES’s “Serial #3” solar dish Stirling system at Sandia’s National Solar Thermal Test Facility.

Wind power is not the answer Steinberger now wants funding for a big pilot project. The idea is to link solar thermal power from Northern Africa to Europe via high-voltage undersea cables. The proposed 3- to 3.5-gigawatt power plant would cost an estimated $32 billion to build. Steinberger believes that 80 percent of Europe's energy needs could be met by solar thermal power plants in the Sahara by 2050.

Wind comes out the clear winner. Concentrated solar power, geothermal, solar photovoltaics, tidal, wave, are good additions to the mix. Hydroelectric is added for its load balancing ability. Nuclear and coal are less beneficial. Corn and cellulosic ethanol should not be included in policy options. Hopefully, the next administration will be wise enough to follow Pr. Jakobson's recommendation . . . and align its subsidies with the right kind of technologies.
