Solar Balloons Get $21 Million In Funding
They look like foil party balloons, but they are actually very efficient solar concentrators. These solar “balloons” were developed by a company called Cool Earth, based in California, and it has just received $21 million dollars in investor funding. The company is now planning to build a 10-megawatt plant of solar balloons in the next couple years. This power plant …

Storing Solar Power In Molten Salt
Solar power is a truly efficient source of energy, but it tends to fluctuate, and, as you might know, it turns off at night. One clever way to alleviate this intermittence is to store solar energy in the form of heat using molten salt. An aerospace company, Hamilton Sundstra, has created a venture called SolarReserve, and it plans to have …

German Town Will Soon Use 100% Renewable Power
There’s a small town in Germany called Dardesheim, that relies almost entirely on renewable sources for its energy needs. The town’s goal is to use 100% renewable power, and become known as German’s “Town of Renewable Energies”. Dardesheim already has some huge wind turbines in place, and many solar roofs installed. Last year they installed an amazing 62 megawatts of …

Blueberries Used To Capture Solar Power
We just reported on the breakthrough in solar dyes in New Zealand. Now, researchers in Italy have discovered that blueberries have natural pigments that absorb sunlight extremely well. Apparently, dark-colored berries outperform most other plant species when it comes to spectral absorption of sunlight. The blueberry pigment, called, anthocyanine, can be used to make dye-sensitized solar cells, which require no …

Delaware May Become Home To The Largest Wind Park In The U.S.
Delaware may become home to the largest wind power plant in the United States. A wind energy developer, Bluewater Wind, hopes to build a 600-megawatt wind park in the waters just off Delaware’s coast. The wind park would power 130,000 homes for over 20 years, at price cheaper than coal or gas, according to Bluewater Wind’s founder Peter Mandelstam. His …

Optimal: Natural Linen Sheets by Area Simone
We recently discovered these 100% natural linen sheets by Area Simone. Linen, which comes from the flax plant, is an optimal material for making sheets. Like hemp, linen does not require pesticides to grow. By contrast, 25% of all pesticides used in the world are sprayed on cotton. Linen is also 2 to 3 times stronger than cotton, has no …

How To Grow Fresh Air
Author B.C. Wolverton originally began his research to investigate creating a breathable environment for a NASA lunar habitat. What came of that research was the discovery that houseplants are the most efficient filters of common pollutants such as ammonia, formaldehyde and benzene. (See our list of the top plants for cleaning the air). In this well laid-out book, Wolverton presents …

Natural Indigo Jeans: Metaefficient?
Originally, jeans were dyed with the color of the actual indigo plant. Today, natural indigo jeans can’t be considered metaefficient because they are expensive and only available as a kind of designer jean. Notwithstanding this, people admire these jeans because of their distinctive, deeply hued appearance. The story behind them is interesting too. There are at least three companies making …
