Sugar Cane Ethanol

November 26, 2008

There are actually two types of ethanol: pure ethanol and absolute ethanol. Denatured alcohol is pure ethanol while absolute ethanol is generally purified ethanol containing no more than one percent water.

Sugar Cane Ethanol

The sugar cane ethanol industry is taking off rapidly, and this is for a number of different reasons. Thirty years ago when one liter of ethanol was worth three times more than one liter of gasoline, most nations would never have considered investing it as a biofuel, ...

Testing the wind: Santee Cooper envisions turbines

November 11, 2008

GEORGETOWN, S.C. - It's a project you might say is full of wind.

The South Carolina-owned utility Santee Cooper is testing whether small-scale wind turbines can be placed along the coast.

Crews on Tuesday installed a 60-foot pole at Georgetown High School with sensors to measure wind speed, direction and frequency. Students will download and help analyze data during the coming months.

It's the first of four towers to be put up along the coast - a second will be set up in the coming weeks a...

Breakthrough?

November 9, 2008

Researchers from the University of South Florida have developed a minuscule solar panel that's just 1/4 the size of a grain of rice. (1/4 the size of a grain of rice!) Yet when you combine 20 or so of the cells, they can create 7.8 volts of electricity. (Nice!!) Sounds good so far, right? It gets better.

The solar cells could easily be incorporated into coatings for buildings and clothing, they're built primarily from abundant and green components carbon and hydrogen, and it's believed that...

Biodeisel- Is it practical?

November 6, 2008
On a commercial scale Bio-diesel is a good temporary substitute for conventional diesel. This is because it can be produced cheaper and has less CO2 emissions. Furthermore, the plants themselves use CO2 therefore making Bio-Diesel a carbon-neutral energy source. The downside is there will never be enough space to support our countries energy needs and other plants need to be taken out before the Bio-Diesel crops can be put it. Bio-Diesel however, can be put to great use in residences. People ...

Obama

November 5, 2008

When i found out that obama won today I thought to myself: what will obama do for alternative energy i got this from his website: http://my.barackobama.com/page/content/newenergy  



The Obama-Biden comprehensive New Energy for America plan will:

     
  • Provide short-term relief to American families facing pain at the pump
  • Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforts to build a clean energy future.
  • Within 10 ye...

Honda Solar Cell?

November 4, 2008
There is all this talk about this "honda solar cell" so I just copied this because it is hard to word this any better

"Honda is a leader in developing innovative new approaches to creating sustainable energy, including solar cells that convert energy from the sun into electricity. It's a technology whose time has come - thanks to next-generation solar cells developed by Honda that use thin film made from a compound of copper, indium, gallium and selenium (CIGS). So we started a whole new compa...

Who invented the first solar cell?

November 2, 2008
According to Encyclopedia Britannica the first genuine solar cell was built around 1883 by Charles Fritts, who used junctions formed by coating selenium (a semiconductor) with an extremely thin layer of gold.

What are Photovoltaic Cells?

November 1, 2008
Photovoltaic cells, usually seen as dark squares in arrays composing the normal home solar panels are evolving into more efficient and less costly units, all because of continuing designs and creations by solar scientists and manufacturers.

The much improved photovoltaic cells are made to focus the sun’s rays that they collected to a much concentrated point. Another change (for the better) of these cells is their size. They shrink while their efficiency level increases. This only means that ...
