U.S. Water Use Declines Despite 30% Population Increase

Tina Casey — Fri, 06 Nov 2009 12:57:28 +0000

The U.S. Department of the Interior reports that overall water consumption in the United States has declined in the past 25 years, even though the population has increased 30% and use by individual American households has increased. The statistics were compiled by the U.S. Geological Survey.

What’s the secret? The 25-year patterns of water consumption revealed in the DOI report provide tantalizing clues about the ability of the U.S. to sustain its legendarily consumer-centric lifestyle while stabilizing and ultimately decreasing its contribution to carbon emissions and other greenhouse gasses.

New Cycle Capital, Draper Fisher Jurvetson Invest $12.2 Million in PACE Solar Renewable Funding

Susan Kraemer — Thu, 05 Nov 2009 03:21:32 +0000

Renewable Funding’s PACE (Property Assessed Clean Energy) solar funding, begun by Cisco DeVries with Berkeley First was a breakthrough in making solar affordable. Now VC high-flyers Draper Fisher Jurvetson, New Cycle Capital, and RWE Ventures have just invested $12.2 million in a first round of financing to make this sober and sensible solar funding available to more homeowners.

Renewable Funding is a business in the Common Good. And it could be big too. There’s potentially a gigaton of greenhouse gas reductions to be made, at no cost to local, state, or federal governments from a $280 billion potential market in PACE solar funding in the US, acording to a UC Berkeley study published in Environment Magazine.

Compost with a Kick: Bokashicycle Brews First Large-Scale Food Waste Fermentation Operation

Tina Casey — Thu, 05 Nov 2009 01:20:39 +0000

Bokashi is a centuries-old Japanese method of recycling household food waste into all-natural compost. By employing a special culture of yeast and other microorganisms, bokashi is a compact, odorless process that takes only days instead of weeks or months. Now the Bokashicycle company is breaking the process out of the kitchen and into a commercial-scale food waste recycling operation, in partnership with New Earth Farm in Hillsboro, Oregon.

New Earth Farm takes in food scraps from Bon Appetit cafeterias on the nearby Intel Hawthorn Farm campus, which provides a significant waste disposal savings compared to disposing the scraps in landfills. Waste reduction is one goal, and in an even more sustainable twist the composted soil is used to grow crops for Abundant Harvest, a local consumer-supported agriculture (CSA) store.

Maldives Goes from Underwater Meetings to Huge Wind Farm

Zachary Shahan — Wed, 04 Nov 2009 15:03:15 +0000

Maldives, one of the most beautiful nations on earth, held the artistic, theatrical event of an underwater government meeting last month, to try to bring more attention to the threats of climate change. Now, they are getting more practical but still grabbing headlines — they are looking to build a wind farm that will generate 40% of the island nation’s electricity needs.

The wind farm plans were announced earlier this week. The project will include 30 turbines and is expected to provide the nation with 75 MW of power, powering the capital city, their international airport, and more!

Ex-United Technologies Rocket Scientists To Build 150 MW Solar Heliostat in Sonoran Desert

Susan Kraemer — Wed, 04 Nov 2009 05:55:01 +0000

SolarReserve; a California start-up spin-out from United Technologies’ Rocketdyne has filed an application with the CPUC to build a 150-megawatt heliostat solar farm with seven hours of after-sunset energy stored in molten salt. These are the rocket scientists responsible for our solar-powered space exploration.

Theirs would be the first heliostat type of solar array to produce grid power in California. Abengoa has several in Spain, and plans one in Arizona. United Technologies has licensed the original technology to the new company SolarReserve and its wholly owned subsidiary Rice Solar Energy, LLC, (RSE).

China Forgets “China-Only Wind Turbines” Policy, but Why?

Zachary Shahan — Wed, 04 Nov 2009 00:18:02 +0000

A couple weeks ago, I wrote about China’s new policy to focus on buying (almost entirely) “China-grown” wind turbines and wind turbine technologies with Chinese patents. That policy wasn’t a big hit internationally and China is back-tracking.

However, is it changing its stance out of international moral pressure or a major financial incentive (recent deal) in the US? And who is to benefit the most from this shift?

Rice University Cooks Up Nanotube Stew

Tina Casey — Tue, 03 Nov 2009 17:35:27 +0000

Researchers at Rice University have announced the discovery of a new breakthrough method for producing carbon nanotubes in bulk fluids. Rice’s new nanotube “stew” could spur the inexpensive mass production of carbon nanotube-based products, much like the plastics industry employed bulk loads of melted polymers as a cheap base for making everything from medical equipment to polyester shirts to plastic bags, and countless other things in between.

Rice’s nanotube research was sponsored in party by U.S. Air Force and U.S. Navy. Aside from their military application, carbon nanotubes have a practically unlimited potential for sustainable civilian products because of their strength, light weight, and electrical conductivity among other properties. Lightweight nanomaterials could boost the gas mileage in cars and airplanes, make thinner and more flexible solar cells, increase the efficiency of lithium-ion batteries (in combination with another new high tech material, graphene), and be used in artificial photosynthesis to generate hydrogen fuel.

Robot Fish to Better Monitor Water Quality

Zachary Shahan — Tue, 03 Nov 2009 16:32:10 +0000

An ecologist and an engineer at Michigan State University are working together to create robot fish that can better monitor various factors in aquatic environments.

Combining the brilliance of nature with some top-notch engineering, these two scientists are on to something and getting the funding for it.

The researchers are breaking ground with this and looking to raise water monitoring to another level.

Welcome Back, Pittsburgh: FLABEG Brings 200 Green Solar Jobs to Steel City

Tina Casey — Tue, 03 Nov 2009 14:09:47 +0000

b nnn

Pittsburgh has been laying the groundwork for a high tech green jobs renaissance ever since its mighty steel mills shut their doors 30 years ago. Now the payoff is coming. FLABEG, the global specialty glass manufacturer, has just opened a solar mirror factory by Pittsburgh International Airport that will bring an estimated 200 jobs to the region, and perhaps as many as 300.

The new $30 million facility will initially focus on its core production line of parabolic curved solar mirrors. Months before the plant opened it already received 700,000 orders, and FLABEG expects to reach a capacity of 1 million mirrors annually.

Scientists Make Foldable 3D Solar Cells around an Optical Fibre

Andrew Williams — Tue, 03 Nov 2009 10:45:11 +0000

Researchers at the Georgia Institute of Technology have made a three-dimensional photovoltaic solar cell around an optical fibre, a revolutionary new approach that could pave the way for a new generation of hyper-flexible solar systems.

According to team-leader Professor Zhong Lin Wang, “Using this technology, we can make photovoltaic generators that are foldable, concealed and mobile. Optical fibre could conduct sunlight into a building’s walls where the nanostructures would convert it to electricity. This is truly a three dimensional solar cell.”
