Solving the carbon dioxide problem

Burning fuel releases carbon dioxide and water vapor. A breakthrough process can reverse this reaction. The carbon dioxide and water vapor can be joined into molecules of methane, ethane, or propane by using sunlight as an energy source. The secret to doing this efficiently requires a particular catalyst with a large surface area.

(A) team (at Pennsylvania State University) found it could enhance the catalytic abilities of titanium dioxide by forming it into nanotubes each around 135 nanometres wide and 40 microns long to increase surface area. Coating the nanotubes with catalytic copper and platinum particles also boosted their activity.

The United States overtook Germany as the biggest producer of wind power last year, new figures showed, and will likely take the lead in solar power this year, analysts said on Monday. Wind accounted for 42% of all new electricity generation installed last year in the U.S.
Another interesting change:
The wind industry now employs more people than coal mining in the United States. (click links in red to learn more).

"Stanford creates 100 million dollar energy research center"
"Stanford University is creating a 100-million-dollar research institute that will focus on energy issues, including the search for ways to reduce global warming, officials said."

"Home turbines fail to deliver as promised, warns British study"
"Home wind turbines are only generating a fraction of electricity promised by the manufacturers while some even fail to yield enough energy to run the turbine's electronics, a British study warned on Tuesday."

"'V-wing' turbine gets study cash"
"An unusual design of wind turbine with a pair of giant vertical wings could one day be generating electricity for the UK Grid."

"China's BYD to bring plug-in hybrid, electric cars to US in 2011"
"China's BYD Auto announced plans Monday to enter the US market in 2011 with a range of electric and plug-in hybrid vehicles. It would likely be the first Chinese automaker to enter the highly-competitive US market and beat many established automakers in offering an extended-range electric vehicle to US consumers."

It's a new day in America: Where should our energy come from now?

On January 21, 2009, there’s going to be a brand new administration in the White house. Defining the energy policy of the United States is going to be a big issue, and one that’s likely to get tackled early on.

The members of the Obama Administration are going to have their own ideas about how our country should get its energy, but what do you think?

Is green energy your one and only? Are you a coal man? A nuclear gal? Or do you fall asleep murmuring “drill, baby, drill”?

Some options are going to be more expensive than others, each will affect the environment differently, and some are going to take more time before they’re ready. So what’s it going to be?

Voice your opinion in Science Buzz’s new poll: Energy and the Obama Administration.

You might not have been able to vote on November 4, but you can vote now, and you can let everyone know why you think what you think.

So if the universe was created by the big bang... then that would mean that from entropy came order. Does that mean that a messy room or desk could create a whole new universe?

If that is the case, what type of universe would be created from your room or desk? What new life forms or environments would there be?

Based on my desk and the mess of papers I feel that my new universe would be very difficult to locate things in... like those caves that have tunnels that you can get lost in.

Is it possible to calculate the "potential energy" of a particular Offensive line compared to a particular Defensive line?

Should a Coach know if they are statistically unable to force the line of scrimmage the direction they want?

Sure - weaknesses can be exploited by double teaming, and running slant plays.....checking the stats on each lineman the coach should be able to choose their strategy before the game....and give the best chance of success

Local economies benefit from global crisis

Buying locally not only saves transportation costs, but also puts money into local economies. Wind turbine gearbox manufacturer, Moventas, based in Finland, is going to build components locally. In addition to about 90 jobs and an initial annual payroll of roughly $4 million, the construction of the $9 million dollar facility will mean more employment for Faribault area workers. Faribault Daily News

Iowa benefits, too

In Newton, Iowa, TPI Composites opened a wind turbine blade manufacturing facility that hopes to provide 500 jobs. The Faribault factory hopes to add 30 jobs per year to total 200. Click here to read about more wind energy jobs created.

Bailout package includes renewable energy incentives

The American Wind Energy Association was relieved by the passage of the Economic Stabilization Act.

These tax credits are essential to the continued growth of wind energy, to the economic and energy security of the United States, and to a successful beginning in the fight against global warming.

Solar gains longer term benefits

The Solar Energy Industries Association (SEIA) also was happy to see the legislation extend the 30-percent federal investment tax credit for both residential and commercial solar installations for 8 years.

“This long-term extension of the solar tax credits will create a domestic solar industry with hundreds of thousands of jobs while providing clean, affordable, carbon-free energy to millions of American families, businesses, and communities.” SEIA press release

Car Magazine online has photos and info about an electric Mini Cooper.

Mini will produce 500 electric Minis as part of its radical ‘Project i’ programme initiated to rethink low-emissions urban mobility (see the forthcoming November 2008 issue of CAR Magazine for full details on this innovative project, out on Wednesday 24 September 2008).

San Antonio has made a deal with the duke. A particularly mighty duke, too, and one that has often been overlooked, despite this duke’s ability to deliver great power.
