Japanese breakthrough will make wind power cheaper than nuclear

Japanese breakthrough will make wind power cheaper than nuclear
NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential. The United States uses about 26.6 billion MWh's, so at the above rate we could satisfy a full one-third of our total annual energy needs. Now what if a breakthrough came along that potentially tripled the energy output of those turbines? You see where I'm going. Well, such a breakthrough has been made, and it's called the "wind lens."

Chemist Hopes 'Artificial Leaf' Can Power Civilization Using Photosynthesis Imagine an artificial leaf that mimics photosynthesis, which lets plants harness energy from the sun. But this leaf would have the ability to power your homes and cars with clean energy using only sunlight and water. This is not some far-off idea of the future. It's reality, and the subject of a jury-prize-winning film in the GE Focus Forward Film Competition. Solar Comes of Age The solar industry is entering a dynamic period as costs decline, demand for electricity continues to grow, and competition heats up. The result has been a rise in M&A and vertical integration as solar energy providers seek to carve out a leading role in the market and ensure their access to customers. Some high-profile bankruptcies have captured headlines in recent months, perhaps the most infamous being government-subsidized Solyndra.

NIF experiments show initial gain in fusion fuel LIVERMORE, Calif. - Ignition -- the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel -- has long been considered the "holy grail" of inertial confinement fusion science. A key step along the path to ignition is to have "fuel gains" greater than unity, where the energy generated through fusion reactions exceeds the amount of energy deposited into the fusion fuel. Though ignition remains the ultimate goal, the milestone of achieving fuel gains greater than 1 has been reached for the first time ever on any facility.

cycle_computer Wireless cycle computer as an RPM monitor Along with the usual amperage and voltage measurements usually associated with wind generators to monitor it's performance, another useful measurement you can make is the RPM of your turbines blades. You can buy a wireless cycle computer from a bike shop for about 25, then youve basically got a cheap RPM meter, amongst other things. You can fix the magnet to your propeller, (watch the balancing) and the sensor to the generators mounting bracket so that they pass each other closely without touching. Unfortunately the wireless facility on the cycle computer only has a maximum range of 70cm, if this is unworkable, a wired version can be used, along with the twisted cables! The sensor sends pulses to the bike computer wirelessly, which then displays many useful measurements including:

Storing Wind Power Energy in Compressed Air Tanks Could Change the World Photo: Flickr, CC Capturing the Wind for Later Use, More or Less... As we've said many times in the past, wind power is great, but to use it to its fullest potential, we need to figure out how to cheaply store the energy that it produces at times when we don't need it (meaning mostly at night). Various schemes have been been proposed to do this, including using batteries from hybrid and electric cars - either at the end of the car's life or with vehicle-to-grid (V2G) connections - and pumping water uphill or holding it in huge reservoirs behind hydropower dams. But we don't yet have that many EVs, and some places don't have much hydro, which is why compressed air storage seems interesting right now. Photo: SustainX

MIT researchers find messy batteries might be better As modern technology demands more and more power, lithium-ion batteries have been getting increasingly dense. There hasn’t been a true breakthrough in battery technology recently, so scientists have been working on ways to fit more components inside the same space. That means very precise work to keep everything neat and tidy. Now a team of researchers from MIT is pointing out some disorder could be a good thing in lithium-ion batteries. One of the issues engineers have had to contend with when layering battery components was that the materials might not hold up and could blend together.

The Impossible Wind Turbine Design That Just Might Work Wind Energy Published on January 27th, 2009 | by Ariel Schwartz Adam Fuller has dedicated his life— and his life savings— to disproving the wind industry’s claim that vertical turbines are ineffective. Last week, I had a chance to talk to the Racine, Wisconsin inventor about his 12 foot diameter, 36 foot tall patent-pending wind turbine.

Glucose-based battery has 10 times energy of lithium: researchers Brazilian sugarcane Humans and batteries--and indeed most other things in the natural world, operate on largely similar principals. Energy is generated somehow, stored, and expended for work. It's only the details that separate these processes, but the gap might shrink with the advent of biobatteries. As ExtremeTech reports, researchers at Virginia Tech have developed a working sugar-powered fuel cell with energy density greater than that of current lithium-ion batteries. Researchers Create Highly Transparent Solar Cells for Windows that Generate Electricity — UCLA Engineering By Jennifer Marcus | July 20, 2012 Transparent Solar Cells UCLA researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside. Their study appears in the journal ACS Nano. The UCLA team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye. They made the device from a photoactive plastic that converts infrared light into an electrical current.
