^{eSolar employees put the final touches on the mirrors used to focus sunlight.}

eSolar is a startup company which is in the process of building solar thermal power plants. It was one of the first startups to earn financial support from Google. This morning it received $130 millions dollars in funding from Google.Org, Bill Gross’ Idealab, Oak Investment Partners, and other smaller investors. The company says it will have a power plant up and running later this year in southern California.

Designed to address the complex issues surrounding large or utility-scale power projects, eSolar’s distributed solar thermal plants achieve economies of scale at 33 MW, and are modularly scaled to fit the needs of large and small utilities.

In order to deliver on the promise of Big Solar, the typical utility-scale installation faces huge construction costs and requires large tracts of real estate, combined with expensive transmission line improvements to bring the power out of the deserts and into the cities. eSolar’s modular approach stands in direct contrast to this ‘bigger is better’ strategy. eSolar has replaced expensive steel, concrete, and brute force with inexpensive computing power and elegant algorithms. This new method of installing a solar power plant minimizes costly civil construction and the use of heavy equipment, dramatically reducing project cost and deployment time.

Centering on eSolar’s 33 MW pre-fab form-factor, the company’s modular design translates to minimal land requirements. The company’s solar power plant solutions are tailored to fit local resources and produce a low environmental footprint, favoring a straightforward siting and permitting process. Myriad locations combined with a multitude of interconnection options mean that eSolar can deliver more clean, carbon free power where it is needed: near the cities and towns where it is consumed.

Straight out of the heart of Copenhagen, comes the Triobike, an innovative cargo bike, that can transform itself into a regular bike and a stroller. It’s no surprise that this bike comes form Copenhagen — the city is filled with urban bikers. With the Triobike, you can transport your kids to school in the cargo bike, then, instead of riding the cargo bike around all day you merely pull out a front wheel from under the cargo bay, put it on the front forks. You can then ride a regular bike or use the cargo section as a stroller.

There’s a short video showing how the bike transforms here.

In Denmark the bike costs about 19,000 kroner for the basic setup, which is about $4000 U.S.

In an ambitious move, a California utility plans to create a massive, distributed “powerplant” by installing a total of 2 square miles of solar cells on the roofs of businesses. Southern California Edison plans to install 250 megawatts’ worth of solar power, generating enough electricity to power 162,000 homes.

Green Wombat reports:

It’s a potentially game-changing move, one that could lower the cost of solar cells as manufacturers ramp up production to meet the utility’s schedule of installing a megawatt-a-week of arrays until it reaches the 250-megawatt target. That alone is more than United States’ entire production of solar cells in 2006 and will generate as much electricity as a small coal-fired power plant, albeit with no greenhouse gas emissions.

The $875 million initiative also marks the first big foray into so-called distributed energy by a major utility. Instead of building a centralized power station and the expensive transmission system needed to transmit electricity to the power grid, Edison will connect clusters of solar arrays into existing neighborhood circuits. A significant hurdle for the massive megawatt solar power plants planned for California’s Mojave Desert is the need in some cases to build multi billion-dollar transmission systems through environmentally sensitive lands to bring the electricity to coastal metropolises.

The initiative will work like this: Edison will lease the warehouse rooftop space from building owners in Riverside and San Bernardino counties. The utility will outsource the installation, and retain ownership of the solar cells.

This plan will be exciting if it is achieved, and it will become a model for other utilities to follow.

Wind power is breaking new records in Spain, accounting for just over 40 percent of all electricity consumed during a brief period last weekend. As heavy winds lashed Spain on Saturday evening wind parks generated 9,862 megawatts of power which translated to 40.8 percent of total consumption. Between Friday and Sunday wind power accounted for an average of 28 percent of all electricity demand in Spain. Spain’s wind power generation equaled that of hydropower for the first time in 2007.

In July the government approved legislation that will allow offshore wind parks to be set up along the nation’s vast coastline in an effort to boost the use of renewable energy sources. While more expensive than land-based wind farms, offshore wind parks can take advantage of stronger, steadier coastal breezes.

Spain, which along with Germany and Denmark, is among the three biggest producers of wind power in the 27-nation European Union, is aiming to triple the amount of energy it derives from renewable sources by 2020.

OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Like LEDs they produce light very efficiently. But OLEDs also have to potential to be made at a very low cost, because they can be printed “roll-to-roll” like a newspaper. GE recently demonstrated the first OLEDs to be made in this manner — the researchers worked for four years on this project. See more at the GE Blog.

Masanori Naruse jogs every day, collects miniature cars and feeds birds in his backyard, but he’s proudest of the way his home and 2200 others in Japan get electricity and heat water - with power generated by a hydrogen fuel cell. The technology - which draws energy from the chemical reaction when hydrogen combines with oxygen to form water.

Developers say fuel cells for homes produce one-third less of the pollution that causes global warming than conventional electricity generation does. Their plain grey fuel cell is about the size of a suitcase and sits just outside their door next to a tank that turns out to be a water heater. In the process of producing electricity, the fuel cell gives off enough warmth to heat water for the home.

The oxygen that the fuel cell uses comes from the air. The hydrogen is extracted from natural gas by a device called a reformer in the same box as the fuel cell. But a byproduct of that process is poisonous carbon monoxide. So another machine in the grey box adds oxygen to the carbon monoxide to create carbon dioxide, which - though it contributes to global warming - is not poisonous.

The entire process produces less greenhouse gas per watt than traditional generation. And no energy is wasted transporting the electricity where it’s actually going to be used.

Nearly every home in Japanese cities is supplied with natural gas for cooking or heating, which could make it relatively easy to spread fuel cell technology there. The potential for widespread use of fuel cells in bigger or more sparsely settled countries is less certain. Many American homes don’t have gas service, for example.

“There are not any real show-stoppers for this technology being used in the US,” said electrical engineering professor Roger Dougal at the University of South Carolina at Columbia.

Dougal said fuel cells are no more hazardous than any stove or water heater. Their major drawback is cost.

“Ultimately, I expect that some fraction of homes will use this technology, but it will be a very long time before a sizable fraction does,” he said in an email.

Naruse is paying $9 500 (about R74 000) for a 10-year lease on a test fuel cell for his home south-west of Tokyo from Matsushita, which sells Panasonic brand products, plans to offer fuel cells commercially in 2009.

Other Japanese companies working on fuel cells for homes include Toyota Motor, which is developing fuel-cell vehicles, and electronics maker Toshiba. Automaker Honda Motor is working with Plug Power, a fuel cell company in the US, to test a home fuel cell generator that also provides hydrogen as fuel for fuel cell vehicles.

Honda hopes domestic use of fuel cell generators will help make fuel cell vehicles become more widespread because owners can refuel at home. It plans to start marketing the FCX Clarity fuel cell vehicle this year in California; it will lease for about $600 a month.

Fuel cells are expensive in part because they don’t last very long. The latest model from Matsushita, for example, lasts about three years.

But the technology is improving. Matsushita says the savings from using fuel cell-generated power will vary by household and climate, but it promises a cost drop of about $50 a month.

Naruse’s family - with three TV sets, a dishwasher, clothes washer, dryer, personal computer and air conditioner - saves about $95 a month. At the same time, conventionally generated electricity remains available to them, should the power generated by their fuel cell run low.

The Japanese government is so bullish on the technology it has earmarked $309-million a year for fuel cell development and plans for 10 million homes - about one-fourth of Japanese households - to be powered by fuel cells by 2020.

Wow, this is a truly non-toxic paint, and it’s going to be sold exclusively at Home Depot. It’s called Freshaire Choice, and it’s a zero VOC paint. According to the EPA, the air inside a home is, on average, two-to-five-times more polluted than the air outside. Paint is a large contributing factor to poor indoor air quality and can emit harmful chemicals, such as VOCs, for years after application.

Another innovative feature of this line of paint is that the tints are also zero VOC. It’s the first paint that can make this claim — on average, up to 150 grams of VOCs are added back into paint once the color is mixed. That means that even if you buy a boutique, all natural paint, as soon as you tint it to the color you desire, you just defeated all the work you put into locating and purchasing the paint (except for naturally pigmented paints, like clay paints).

The Freshaire tinting system uses pre-measured packets of dry tint that color the paint without adding any VOCs to the paint. This zero VOC system is an industry first. No other tint system for paint can make this claim. Another innovation is that the tint comes in a packet that dissolves into the paint completely. By using pre measured, standardized packets, Freshaire ensures consistent colors no matter when you buy more paint. The only drawback to the system is that you can only use the 65 colors that are currently available — so no custom matching.

Freshaire Choice has a GreenGuard certification (one of the most stringent independent test laboratories in the United States).

Freshaire uses 100% recycled materials for the can, the can is recyclable when you are done, 75% recycled fiber material is used for the can’s label, the label is printed with soy ink. Another innovation is that the paint chips are also completely recyclable as well being made from recycled materials. As far as I know, only Freshaire allows you to recycle actual sample paint chips.

The Freshaire Choice Paint will be exclusively available at The Home Depot nationwide beginning April 1, 2008. The one-gallon containers will be sold at a manufacturer’s suggested retail price of $35 - 38. The Freshaire Choice Paint product assortment consists of flat, eggshell and semi-gloss finishes, as well as drywall interior primer and ceiling paint. For more information or to request a free sample, visit www.thefreshairechoice.com or call 1-866-880-0304.

Sunscreens that pollute the water are not efficient. This is especially true in the ocean, where it’s estimate that 4000-6000 tons of sunscreen wash off swimmers every year. A company called Caribbean Solutions is introducing a biodegradeable sunscreen nationwide.

This sunscreen is free of petroleum derivatives — instead, the active ingredients are titanium dioxide and zinc oxide. These minerals scatter and reflect UVA and UVB rays, while petrochemicals absorb them. Moreover, conventional sunscreens contain four questionable chemicals: octinoxate, oxybenzone and 4-methylbenzylidene camphor, and the preservative butylparaben.

Dr. Celia Ferreira formulated Caribbean Solutions SolGuard (in SPF 4, 8, 15 and 25) with botanical ingredients, including wild pansy, green coffee bean extract and hibiscus. Titanium dioxide and zinc oxide protect from both UVA and UVB rays, while sunflower and cucumber oils soothe and hydrate the skin. The sunscreen is available from Carribean Sol.
