Technology Review: High-Efficiency Generators for Hybrid Vehicles

Wed, 01 Oct 2008 14:53:48 -0000

Highlights and Sticky Notes:

An unconventional engine design is attracting attention as a potential alternative to hydrogen fuel cells or conventional engines in some hybrid vehicles. Called the free-piston engine, it could be used to generate electricity as efficiently as fuel cells yet cost less.

ecosalon :: the green gathering :: 9 Life Changing Inventions the Experts Said Would Never Work

Sun, 07 Sep 2008 09:46:42 -0000

Highlights and Sticky Notes:

The lightbulb. The telephone. Email. If you're a specialist in your field, there are two ways to become a household name: create something new...or claim it can never be done. If you want to be remembered on the Internet, choose the second one. Here are 9 examples of breakthroughs, inventions and innovations the experts were completely wrong about.

Scientists Fabricate Room Temperature Superconducting Material

Mon, 09 Jun 2008 18:45:18 -0000

Highlights and Sticky Notes:

A new breakthrough superconducting material fabricated by a Canadian-German team has been made out of a silicon-hydrogen compound and does not require cooling. The implications of the discovery are enormous and could transform the way people live by cutting power usage from everything from refrigeration to cell phones.

Technology Review: Lithium-Ion Electric Car

Wed, 23 Apr 2008 04:29:56 -0000

Highlights and Sticky Notes:

Light and compact lithium-ion batteries sound great for electric vehicles--aside from their historical tendency to catch fire. But recent advances in electrode chemistry have made them much safer. One of the first vehicles to use the new batteries comes from a Norwegian company, Think. By year's end, Think plans to start selling ultracompact electric cars with a range of more than 100 miles. A123 Systems of Watertown, MA, and Indianapolis's EnerDel will provide the batteries.

Peak Energy: We're Off To See The Wizard - Storing Energy Using Ammonia

Wed, 23 Apr 2008 04:25:14 -0000

Highlights and Sticky Notes:

The first of these is being put together by a South Australian company called Wizard Power, which is trying to commercialise research from the Australian National University (ANU) - a solar concentrator dish and a closed loop thermochemical energy storage system using ammonia.

Nanomaterial turns radiation directly into electricity - energy-fuels - 27 March 2008 - New Scientist Environment

Fri, 11 Apr 2008 19:30:47 -0000

Highlights and Sticky Notes:

Electricity is usually made using nuclear power by heating steam to rotate turbines that generate electricity.

But beginning in the 1960s, the US and Soviet Union used thermoelectric materials that convert heat into electricity to power spacecraft using nuclear fission or decaying radioactive material. The Pioneer missions were among those using the latter, "nuclear battery" approach.

IEEE Spectrum: Silicon Nanowires Turn Heat to Electricity

Sat, 12 Jan 2008 21:39:09 -0000

Highlights and Sticky Notes:

Two separate teams, one at Caltech and the other at the University of California, Berkeley, reported that they could increase silicon's ability to convert heat into electric current by as much as 100 times. If they can use what they've learned to improve silicon even further, or translate their findings to other materials, the discovery could lead to new ways to cool computer chips, build refrigerators, or get more power out of car engines.

Are electric vehicles really any better for the environment than gas-guzzling cars? - By Brendan I. Koerner - Slate Magazine

Sun, 30 Dec 2007 13:50:04 -0000

Highlights and Sticky Notes:

Would electric cars really be any better for the environment than our current gas guzzlers? So much of our electricity comes from coal, after all, which isn't exactly the cleanest source of energy. Might we all be better off simply upgrading to more fuel-efficient vehicles—that is, ditching our Hummers in favor of Toyota Corollas?

IGCC's Future Hinges on Workable Carbon Framework

Thu, 20 Dec 2007 14:06:55 -0000

Highlights and Sticky Notes:

One of the leading alternatives for producing clean power from coal -- Integrated Combined Cycle Gasification (IGCC) technology faces a precarious future due to rising capital costs and regulatory uncertainty. A process of gasifying coal that allows capture of carbon dioxide emissions, IGCC has tremendous potential for meeting future baseload generation demand but project momentum has slowed dramatically in 2007, according to a new study from Emerging Energy Research (EER). Despite delays or cancellations of several prominent IGCC projects in 2007, 48 projects with a combined capacity of over 25,000 MW remain in the global IGCC pipeline, according to EER.

Technology Review: Storing Solar Power Efficiently

Tue, 02 Oct 2007 12:59:09 -0000

Highlights and Sticky Notes:

Solar proponents love to boast that just a few hundred square kilometers' worth of photovoltaic solar panels installed in Southwestern deserts could power the United States. 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. >
