Kite Assisted ShipsTech Level: 10 Using the wind for propulsion on the seas is hardly a new idea; it is in fact one of mankind’s oldest ocean-going technologies. Desalination without a membrane. People have wanted to turn sea water into drinking water for years.
Unfortunately, it's not cheap. The reverse osmosis process, which separates out salt with a membrane, costs about 50 cents per cubic meter of water. Reverse osmosis systems also have to be monitored so that the membrane doesn't get fouled or clogged. Ocean currents can power the world, say scientists. Seaweed study boosts prospects for marine biofuels. Seaweed biofuel farms have come a step closer to reality with an improvement in the way seaweed sugars can be converted to ethanol.
Dried seaweed can be fermented to produce ethanol but breaking down galactose, the dominant sugar in seaweed, is a slow process. Now, researchers have modified the expression of three genes of the yeast Saccharomyces cerevisiae, which is used in the fermentation process to break down sugars to ethanol. The improved strain creates more enzymes, leading to a 250 per cent increase in the rate of galactose sugar fermentation compared with a control strain, according to a paper in the current issue of Biotechnology and Biongineering (March).
Tar sands oil and Keystone XL's dirty secret. Picture this: a large, multibillion dollar Canadian corporation comes to the president of the United States and wants to build a 1,700-mile oil pipeline from Canada all the way to the Gulf of Mexico.
After reviewing the project, it becomes clear that instead of reducing America's reliance on oil from overseas, this pipeline would carry oil across America, risking spills on our land and waters, just to export the oil to other countries. In addition, the pipeline would increase gasoline prices in America, add to our air pollution, and most importantly, be a major setback in the fight to reverse global warming. Clearly, the president would say no to Big Oil on this one, wouldn't he? This is the exact question facing President Obama as he reviews TransCanada's proposed Keystone XL tar sands oil pipeline. Keystone XL could carry up to 900,000 barrels of dirty tar sands oil across America every day.
Keystone XL: Nebraskans take pipeline issue all the way to the White House. The woman seated before the row of suited state legislators in her red Husker team hoodie was choking on tears.
She had grown up on a farm in Nebraska. Her parents had grown up on farms, in the days before electricity and running water, and now she said generations of toil and sweat could be destroyed in an instant by a $7bn pipeline project. A leak from the pipeline, which would run from the tar sands of Alberta to the refineries of Texas, could poison her land forever, Donna Roller told the hearing this week during a special session of the state legislature.

Financing Solar Energy Projects for Municipalities - Sustainable City Network, Inc.: Finance: news, solar energy, solar panels, solar america communities, national league of cities. How can municipalities help generate electricity from solar energy without actually paying for the development?
The answer, increasingly, is through Power Purchase Agreements (PPAs), a financing device that entices private developers with tax credits and locks down energy costs for their public-sector partners. While there are numerous grants and municipal bond programs that help local governments pay for their own solar installations, one federal authority said cities should think twice about investing in solar if they haven't already made their municipal operations as energy efficient as possible.
