$2000 Battery Can Power House for One Day

Popular Mechanics: Without a way to store their power, no number of solar panels will free a home from the electrical grid. Researchers at Utah-based Ceramatec have developed a new battery that can be scaled up to store 20 kilowatt-hours—enough to power an average home for most of a day. An easy sell for solar users, but it could also allow the grid-bound to stockpile energy during less expensive off-peak hours.

The new battery runs on sodium-sulfur—a composition that typically operates at greater than 600 F. “Sodium-sulfur is more energetic than lead-acid, so if you can somehow get it to a lower temperature, it would be valuable for residential use, Ralph Brodd, an independent energy conversion consultant, says.

Ceramatec’s new battery runs at less than 200 F. The secret is a thin ceramic membrane that is sandwiched between the sodium and sulfur. Only positive sodium ions can pass through, leaving electrons to create a useful electrical current. Ceramatec says that batteries will be ready for market testing in 2011, and will sell for about $2000.

Hyperion Small Modular Nuclear Power Reactors. Maybe (:

leave a comment »

hyperionreactor1Hyperion Power Generation: Invented at the famed Los Alamos National Laboratory, Hyperion small modular power reactors make all the benefits of safe, clean nuclear power available for remote locations. For both industrial and community applications, Hyperion offers reliable energy with no greenhouse gas emissions. Hyperion power is also cheaper than fossil fuels and, when you consider the cost of land and materials, watt to watt, Hyperion’s innovative energy technology is even more affordable than many developing “alternative” energy technologies.

Small enough to be transported on a ship, truck or train, Hyperion power modules are about the size of a “hot tub” — approximately 1.5 meters wide. Out of sight and safe from nefarious threats, Hyperion power modules are buried far underground and guarded by a security detail. Like a power battery, Hyperion modules have no moving parts to wear down, and are delivered factory sealed. They are never opened on site. Even if one were compromised, the material inside would not be appropriate for proliferation purposes. Further, due to the unique, yet proven science upon which this new technology is based, it is impossible for the module to go supercritical, “melt down” or create any type of emergency situation. If opened, the very small amount of fuel that is enclosed would immediately cool. The waste produced after five years of operation is approximately the size of a softball and is a good candidate for fuel recycling.

Perfect for moderately-sized projects, Hyperion produces only 25 MWe — enough to provide electricity for about 20,000 average American sized homes or its industrial equivalent. Ganged or teamed together, the modules can produce even more consistent energy for larger projects.
