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.

    excerpt:
    "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-

Making "Renewable" Viable: Drexel Engineers Develop New Technology for Grid-Level Elect... - 0 views

  •  
    "The team's research yielded a novel solution that combines the strengths of batteries and supercapacitors while also negating the scalability problem. The "electrochemical flow capacitor" (EFC) consists of an electrochemical cell connected to two external electrolyte reservoirs - a design similar to existing redox flow batteries which are used in electrical vehicles.

    This technology is unique because it uses small carbon particles suspended in the electrolyte liquid to create a slurry of particles that can carry an electric charge."

Land Art Generator Initiative - 0 views

  • It is important to note is that there is a lot more out there than what we see in the everyday. In fact, you will see here that there are dozens of proven methods of harnessing the power of nature in sustainable ways. Some of the more interesting examples that may be applicable as a medium for public art installations are the translucent thin films which can be flexible and offer interesting hues and textures, piezoelectric generators that capture vibration energy, and concentrated photovoltaics, which allow for interesting play with light. But the possibilities are endless and new designs are coming into the market all the time that can be artistically integrated into beautiful sustainable infrastructure.

wastewatts : Sustainable Technology Discussion Group - 2 views

  •  
    "Energy security is rapidly becoming a major concern for citizens of both developed and developing countries.

    We have grown totally dependent on low cost oil and gas for our everyday lives.

    As increased pressure is put on the remaining reserves, prices are rising inexorably, and alternatives must be sought.

    This requires a change of lifestyle for the 21st Century.

    Wastewatts is a technology discussion forum that looks at ways in which we might change our fossil fuel dependent lifestyles, off-setting petroleum with renewable fuels or those derived from industrial or agricultural waste."

Wave and Tidal Energy on the Rise: But Will it Work? | Renewable Energy News Article - 2 views

  •  
    Tidal & wave is the wild card for the energy sector. With 45 kW/m power in wave fronts, it's a sources of renewables that is already concentrated by nature. But after many decades, the sector remains stuck in concepts and trials. The La Rance facility by EDF is operating since the 70s - if it had been a dream technology, we'd have seen more of this by now.

Commodity Cycles and Renewable Energy Costs | The Energy Collective - 0 views

  • The rationale for continued cost declines that I encounter most often is based on volume: If we install more wind and solar capacity, costs will fall in a virtuous cycle, making subsequent installations cheaper and prompting even more of them. The underlying logic behind this argument derives from empirically observed "experience curves", in which cost components such as manufacturing fall by a set percentage for each doubling of cumulative output. The problem with these curves is that they tend to flatten out fairly quickly, delivering their maximum effect in the early years of a technology, when doublings are frequent.
