Japanese firm wants to transform the Moon into a giant solar power plant - 1 views

  • The Shimizu Corporation, a Japanese construction firm, has recently proposed a plan to harness solar energy on a larger scale than almost any previously proposed concept. Their ambitious plan involves building a belt of solar cells around the Moon’s 6,800-mile (11,000-kilometer) equator, converting the electricity to powerful microwaves and lasers to be beamed at Earth, and finally converting the beams back to electricity at terrestrial power stations. The Luna Ring concept, the company says, could meet the entire world's energy needs.

FT.com | FT Energy Source | Solar energy from space, anyone? - 0 views

  • Something about this reminds us of Desertec: ambitious, expensive (though not in the same league as the €400bn Desertec), and with a bunch of big name vendors involved (apparently - there is no sign of it on either Mitsubishi’s or IHI’s websites). It’s also a long way off and far from certain.
  • The 1GW station would involve four square kilometres of solar panels. It’s estimated to be about 2,000bn yen ($21bn) and 30 years away, and it would have to become much, much cheaper to get out there:

6 Reasons to Stay On the Electric Grid : CleanTechnica - 0 views

  • Imagine using only the energy from the sun to power your home. You would never have to pay an electric bill again and or be impacted by power outages.  It may sound great, but there are numerous advantages to having a solar home that is on-the-grid when available.

Evaluating the Cleanliness of Solar Photovoltaics Can Be Complicated : CleanTechnica - 0 views

  • Take a good look at panels that have been installed for several years and you will notice discontinuities and shiny areas where the components have been damaged and where the power production is reduced.
    • Hans De Keulenaer
       
      There's an idea. Only once I've seen a paper on long-term performance of panels.
  • Though there are no visibly moving parts in a solar PV panel, there are many parts of the system where continuous chemical and physical reactions take place that can eventually lead to system degradation and failure.
    • Hans De Keulenaer
       
      Makes sense. Roofs have no moving parts as well, yet we're always concerned of infiltrations.
  • Leaves and snow are particular nuisances for rooftop solar panels, but sand and bird droppings can be important in some areas as well.

      Few solar advocates are part of the BC sector.

    Solar photovoltaic (PV) cells are a popular and often discussed (see, for example Atlantic City Convention Center Plans Largest Solar Roof in U.S., 10% of U.S. Electricity From Solar by 2025, SF Passes Largest City Solar Program in U.S. (Finally), all of which were published within the past week) form of "renewable" or "green" energy, but a casual scratching of the surface knowledge that many people have about the technology reveals some troubling details.

Carectomy.com: Removing Cars from People - Australia Announces World's First Solar-Powe... - 0 views

  • The Tindo bus is the stuff of car-free, green, geeky dreams: It epitomizes efficient urban transportation and energy use, and to top it all off, it’s free. Our friends at EcoGeek first tipped up off to the story.
  •  
    World firsts are always interesting. Here, a bus network in Adelaide, Australia will operate using a solar photovoltaic system. Of course, the region has enough sun to keep energy levels topped up. In regard to using solar for other city systems, it will be interesting to see how this model works .

India to provide subsidy for solar power plants | Environment | Reuters - 0 views

  •  
    India will subsidize the running of solar power plants to help develop a renewable energy infrastructure, where high costs can be prohibitive, the minister for renewable energy said on Wednesday.

    Renewable energy accounts for about 7.5 percent of India's installed generation capacity of 127,673 MW, a rate that compares favorably with much of the rest of the world.

    Much of this capacity is wind-based, and the share of solar power is small.

    "My ministry will provide financial assistance amounting to 12 rupees (30 cents) per kilowatt hour in case of solar photovoltaic and 10 rupees per kilowatt hour in case of solar thermal power fed to the electricity grid," Vilas Muttemwar said in a press conference.

Solar Beads Could Cut Costs By 50% »» MetaEfficient Reviews - 0 views

  • “We use one-fifth of the raw silicon material compared with traditional PV cells,” he says.

    spherical_cells_x220.jpgThis can make a huge difference to the overall cost of producing solar cells

  • The ultimate goal is to make them 50 percent cheaper than existing cells by 2010, he says.
  • These work like car headlights but in reverse, ensuring that any light hitting the reflector is directed toward the sphere.

Technology Review: Focusing Light on Silicon Beads - 0 views

  •  
    A company in Japan has developed a novel way of making solar cells that cuts production costs by as much as 50 percent. The photovoltaic (PV) cells are made up of arrays of thousands of tiny silicon spheres surrounded by hexagonal reflectors.

Inflatable Solar Arrays Cost Up To 25X Less - 0 views

  • Also the solar units are so light weight that they can be suspended on steel cable lines rather than each having their own base connected to the ground. This rigging system allows for minimal land use disruption, 60 times less steel material and faster installation. The cables double as a control mechanism to align the units toward the sun.

    could this become a trend?

Technology Review: Storing Solar Power Efficiently - 0 views

  • Their schemes come with a caveat, of course: without backup power plants or expensive investments in giant batteries, flywheels, or other energy-storage systems, this solar-power supply would fluctuate wildly with each passing cloud (not to mention with the sun's daily rise and fall and seasonal ebbs and flows). Solar-power startup Ausra, based in Palo Alto, thinks it has the solution: solar-thermal-power plants that turn sunlight into steam and efficiently store heat for cloudy days.
