Logging Occupancy to Optimize Energy Use - Energy Efficiency Markets - 0 views

  • Every occupant in a building creates demand for lighting, ventilation, thermal comfort, and electrical power. Lighting, heating, and cooling unoccupied spaces is a huge source of energy waste in buildings, and many studies have shown that building occupancy profiles have a significant impact on building energy use and operational controls.

    Closer alignment of occupancy patterns to building equipment schedules can be an effective low-cost/no-cost energy efficiency strategy leading to more intelligent control of buildings, a better balance between occupant comfort and energy savings, and lower utility bills. This includes, but is not limited to, HVAC temperature set points, lighting schedules, and economizer schedules.

Teenager Designs Safer Nuclear Power Plants - Yahoo! News - 2 views

    Very interesting presentation at the TED Conference.  Not quite a nuclear battery, but a really good redesign of nuclear power systems.

    "Instead of finding a new way to boil water, Wilson's compact, molten salt reactor found a way to heat up gas. That is, really heat it up.

    Wilson's fission reactor operates at 600 to 700 degrees Celsius. And because the laws of thermodynamics say that high temperatures lead to high efficiencies, this reactor is 45 to 50 percent efficient.

    Traditional steam turbine systems are only 30 to 35 percent efficient because their reactors run at low temperatures of about 200 to 300 degrees Celsius.

    And Wilson's reactor isn't just hot, it's also powerful. Despite its small size, the reactor generates between 50 and 100 megawatts of electricity, which is enough to power anywhere from 25,000 to 100,000 homes, according to Wilson.

    Another innovative component of Wilson's take on nuclear fission is its source of fuel. The molten salt reactor runs off of "down-blended weapons pits." In other words, all the highly enriched uranium and weapons-grade plutonium collecting dust since the Cold War could be put to use for peaceful purposes.

    And unlike traditional nuclear power plants, Wilson's miniature power plants would be buried below ground, making them a boon for security advocates.
    According to Wilson, his reactor only needs to be refueled every 30 years, compared to the 18-month fuel cycle of most power plants. This means they can be sealed up underground for a long time, decreasing the risk of proliferation.

    Wilson's reactor is also less prone to proliferation because it doesn't operate at high pressure like today's pressurized-water reactors or use ceramic control rods, which release hydrogen when heated and lead to explosions during nuclear power plant accidents, like the one at Fukushima in 2011.

    In the event of an accident in one of Wilson's reactors, the fuel from the core would drain into a "sub-critical" setting- or tank-

Energy Harvesting the Next Big Thing for the Smart Grid | The Energy Collective - 0 views

  • Solar panels capture energy from light and convert it to electricity.   This is the most visible form of energy harvesting, but it is hardly the only one.  Energy harvesting captures energy lost as heat, light, sound, vibration, or movement.  Devices that harvest or scavenge energy can capture, accumulate, store, condition, and manage this energy into electricity for consumption.  That’s important, because our existing electricity infrastructure is extremely wasteful in its use of energy.  For instance, today’s technologies used in electricity generation are not energy efficient.  Traditional gas or steam-powered turbines convert heat to mechanical energy, which is then converted to electricity.  Up to two thirds of that energy input is lost as heat.  Those old incandescent bulbs (technology invented by Thomas Edison in 1879) were real energy losers too.  Ninety percent of the electricity flowing into incandescent bulbs ends up as waste heat. That’s lost energy, which is why smart federal legislation banned incandescents in favor of more energy efficient sources of lighting starting in 2012.

Clever MIT floating wind turbines can store power for when the wind doesn't blow : Tree... - 0 views

  • A single 25-meter sphere at a depth of 400 meters could store up to 6 megawatt-hours of power, so a large offshore wind farm with hundreds or even thousands of those could become a giant on-demand battery, potentially producing as much power as large power plants (it all depends on how far you scale up the idea). These anchor/storage spheres could be built on land and then brought out to sea. No need for too much super-expensive deep sea construction.

    Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience. This could yield an estimated storage cost of about 6 cents per kilowatt-hour — a level considered viable by the utility industry.

Battery Could Provide a Cheap Way to Store Solar Power | THE GREEN ENERGY BLOG - 0 views

  • There’s a promising new entry in the race to build cheap batteries for storing energy from solar panels and wind turbines. Stanford researchers led by Yi Cui, a professor of materials science and engineering, have demonstrated a partially liquid battery made of inexpensive lithium and sulfur. Cui says the battery will be easy to make and will last for thousands of charging cycles.

    Cui believes that the material and manufacturing costs of the battery might be low enough to meet the Department of Energy’s goal of $100 per kilowatt-hour of storage capacity, which the DOE estimates will make the technology economically attractive to utilities. Existing batteries can cost hundreds of dollars per kilowatt-hour of capacity, although several companies are working to commercialize cheaper ones (see “Ambri’s Better Battery” and “Battery to Take On Diesel and Natural Gas”).
