This Valentine's Day instead of buying fresh cut flowers that only last a few days and are totally full of pesticide toxins - Make your sweetie flowers that are eco-friendly because they are made from some extra scrap fabric and will last for years. Here is a great how-to guide by Becky Striepe over at ...

Brian Keane, who leads a nonprofit called Smart Power, wants to do for renewable energy what the "Got Milk?" campaign does for milk and what the "Fabric of Our Lives" campaign does for cotton-he wants to make wind and solar and hydropower and geothermal energy really cool, and get more people to buy them. Here's one way he is going about it, with a little help from a friend:

Photovoltaic cells are better known by their media name "Solar Cells".

Technology Review has an update on cheap, energy efficient OLED lighting - Ultra-Efficient Organic LEDs. An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting. The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who led the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing. In recent years, many countries have begun looking to switch from incandescent lighting to compact fluorescent bulbs because the latter are so much more energy efficient. There has also been a lot of interest in using light-emitting diodes (LEDs) for displays and general lighting, again because of the potential energy savings they offer. But with both fluorescent and LED lighting, the quality of white light produced has always left something to be desired. Fluorescent lighting can make people appear unhealthy because less red light is emitted, while most white LEDs on the market today have a bluish quality, making them appear cold.
