A few weeks from now, the Andasol 1 solar thermal power plant in Andalucía, Spain, will begin charging the largest installation built expressly for storing renewable energy (other than the tried-and-true hydroelectric dam, of course). Heat from the solar thermal power station’s 510 000-square-meter field of solar collectors will be stored in 28 500 tons of molten salt—enough to run the plant’s 50-megawatt steam turbine for up to 7.5 hours after dark.

More such plants are on the way in Spain. Solar Millennium and its Spanish partner expect to start up a twin plant, Andasol 2, next spring and plan to begin building a third 50-MW plant early next year.

Spain’s Abengoa Solar and Sener, meanwhile, are each testing solar thermal plants with integrated molten-salt storage. Both use a “power tower” configuration in which arrays of mirrors direct sunlight onto a central solar receiver where the light directly heats a molten salt. This configuration matches that of Solar Two, a 10-MW solar thermal demonstration plant at Sandia National Laboratories, in New Mexico, built in the 1990s. The power-tower design makes energy storage cheaper and more compact because the salts can be safely heated well beyond the limit of the synthetic oils.

reutersvideo - Jan. 4 - US researchers have grown a beating heart in a laboratory from the cells of newborn rats.Researchers hope this will eventually lead to the ability to build organs.

The editors of Entrepreneur.com sifted through hundreds of inventions that became available within the past year to compile a diverse list of innovative, practical and fun products.

1. iPhone - which consumers camped out for prior to its June debut, is the obvious choice for any “Best of 2007″ list. Much more than a phone, it also features an iPod, a camera and the internet, all in one. The multi-touch display allows you to control everything with your fingertips. Zoom in and zoom out on maps to determine your driving route and use the Visual Voicemail to listen to your messages in any order you choose.
2. Kindle - Since it became available in November, Amazon.com has struggled to keep this new electronic reading device in stock. The revolutionary portable reader downloads books, blogs, magazines and newspapers. The Kindle features a high-resolution electronic paper display that looks like real paper. Readers can choose from more than 90,000 books available in the Kindle store, including new releases and New York Times bestsellers. Aside from the cost of books, which run around $9.99, there are no monthly wireless bills or service commitments.
3. ZPrinter 450 - This device can transform electronic 3D data into colorful, handheld physical models. It can be used to create architectural concepts, landscapes, engineering product designs, electronic entertainment objects and medical information. The ZPrinter 450 is the third 3D printer made by Z Corp. and is touted as the most compatible with contemporary office environments. The ZPrinter 450 breaks down 3D printing into seven easy steps. It also includes automatic setup, power loading and self-monitoring of materials and print status.
4. iRobot Looj Gutter Cleaning Robot - iRobot, maker of the Roomba, says it’s the first product designed to make gutter cleaning faster, easier and safer. The robot is controlled by a wireless remote that’s also a detachable handle. The Looj can clean a 60-foot section of gutter in just 10 minutes. It drives under gutter straps while dislodging and eliminating dirt, leaves and debris. The robot works with standard K-style, aluminum, copper, metal or vinyl gutters.
5. QwikGrip - After eight years of development, inventor Leonard Duffy has created the Velcro of the future–a fastening technology that snaps into place and slides into full engagement. His “slidingly engaging” systems are applicable to many industries, including apparel, sports, health care, safety and military. Duffy says his invention can bind a new plastic cast or even take the place of shoe laces. Right now, the fastening technology is on the market as a business-to-business licensing opportunity, though it’ll be available for consumer purchase in 2008.
6. GreenSwitch - Originally, the GreenSwitch system was designed for controlling energy use in hospitals and hotels. After reducing energy costs by 25 to 45 percent in those industries, the technology has now entered the consumer market. The wireless system can reduce home energy consumption by turning off all designated light switches, wall plugs and air conditioning with the flip of a switch. After flipping the switch back on, all plugs and systems return to normal modes. The system can be retrofitted in an existing home or added to a new home during construction.

The owner of a bike-tour company improves his business using various wireless technologies.

After racing bicycles professionally for two years and realizing that I was no Lance Armstrong, I found another way to make a living on a bike. I had spent 20 years organizing bike treks with friends through the Alps, the hills of Tuscany and the countryside of Provence. Noticing a growing appetite for such trips, I founded Destination Cycling (destinationcycling.com) in 2002. I now run tours on my bike 70 days a year.

We began offering trips for serious cyclists that duplicated famous races such as the Tour de France in 2005. Our clients are typically Fortune 500 executives. The journeys are very complex for me to manage. We ride 100 miles or more a day for 21 days. I never know when a tire will blow or a hail storm will strike. Our customers pay us $30,000 for the experience of a lifetime and, in some instances, six figures for exclusive tours. They expect us to plan for the unexpected.

Pure Digital, which makes disposable cameras sold in drugstores, is launching a new pocket-sized camcorder called Flip Video on Tuesday. The product, which will be available at Target, Costco, Best Buy and on Amazon.com, comes with a USB arm to connect to a personal computer or Mac.

Jonathan Kaplan, CEO of San Francisco-based Pure Digital, said the company hopes to make it easier for people to record and share video online. To that end, the camcorder comes with built-in software that makes it easy for people to upload their videos onto Google-owned YouTube or Grouper, an online video site owned by Sony.

Pure Digital is selling two versions of Flip Video, one that can hold about 30 minutes of video and another that stores an hour. The 30-minute version will cost about $119 while the 60-minute version will sell for around $149. Both devices run on standard AA batteries.

Online video is becoming the killer application of the Internet as b-to-b marketers embrace it as an integral part of their marketing programs, using it in such disparate formats as 15-second banner ads and long-form documentaries.

Spending on online video advertising will more than triple in the next three years, growing from $775.0 million this year to $2.90 billion in 2010, according to research company eMarketer.

With the anticipated surge in spending, media companies are scrambling to get in on the action, as demonstrated by the partnership announced last month by NBC Universal and News Corp. to form an online video ad network.

In announcing the as-yet-unnamed venture, News Corp. President-COO Peter Chernin called it “the largest ad platform on earth,” with an audience that will reach about 96% of the U.S. Web viewing audience. The video network will be distributed by partners including Microsoft Corp.’s MSN, News Corp.’s MySpace, Time Warner’s AOL and Yahoo.

Already, the video venture has lined up charter advertisers including Cisco Systems, General Motors Corp. and Intel Corp.

When the air conditioner caught fire three years ago, Kate Khosla thought it was time to pull the plug — literally — on her husband Ron’s efforts to invent a better compressor-condensor-evaporator.

Khosla’s idea was simple: he thought he could build a gizmo that would allow an ordinary air conditioner to take a room’s temperature down as low as 32 degrees. Not all of his prototypes blew up, but neither did any of his early models last long enough to get the job done.

You could find Khosla juggling about a dozen small boxes at the New Paltz post office, sending his patent-pending CoolBot to farmers like himself. With next to no publicity or marketing, the CoolBot is becoming a very hot item. And it’s poised to go more places than the farm. He’s sold about 80 units at $250 a pop and has placed material orders that will allow him to build another 500.

It’s all a marvel to Khosla, who calls himself a “reluctant capitalist” who never intended to sell his invention. He’d thought initially to explain the process to other farmers and let them build their own. That idea didn’t work out, but the Khoslas don’t seem too broken up about it.
