This weekend is the Independence Day holiday– and that means we’ll be lighting up the BBQ, consuming beverages, throwing out paper plates and generally wasting resources while we enjoy ourselves. So we’ve come up with a list of easy things you can do to lower the environmental impact of this fun, important holiday. It’s Independence [...]

Can the U.S. Government Be an Effective Cleantech VC?
Posted in June 29th, 2009
As stimulus funding leads some industry insiders to think of Washington as “the new Wall Street” for green energy, some investment experts say they’re concerned about the government’s new role. “I worry about the government as a dealmaker in this space,” said Tom Bratkovitch, director of LP Capital Advisors, a consulting firm for private-equity investors, at a Thomson Reuters conference in Palo Alto, Calif., this week. “I just don’t know if the government is the best one to make decisions in this space.”
After all, the federal government has supported some technologies that have not panned out, while missing some that have ultimately been successful. The government also has a reputation for moving slowly – though the Department of Energy certainly is trying hard to get stimulus money out as quickly as possible – and the applications for the grants and loan guarantees can be extremely time-consuming.
Ultrasound Cleans Polluted Water, Makes Catfish Tastier
Posted in June 29th, 2009
One solution to the world’s water pollution problems could be something you can’t taste, touch, see, smell, or hear. Especially hear. Ultrasound, the range of frequencies beyond the limits of human hearing, is starting to emerge as an effective water treatment that is more sustainable than chemical dosing. Researchers are discovering that ultrasound performs well on algae, and that’s only the beginning. Ultrasound can remove a variety of pollutants in water, including those that affect the taste of America’s favorite fish, the catfish.
Roof Shingles Made from Recycled Plastic and Rubber
Posted in June 28th, 2009
Now, I’m no Bob Villa, but as a new homeowner who has to replace his roof, I have been looking into environmentally friendly alternatives to either asphalt or “premium” wood. And Enviroshake definitely falls into the first category. Made primarily of reclaimed materials, Enviroshake might just be the answer.
GE to Cleantech Startups: We Can Help
Posted in June 26th, 2009
Cleantech startups have stopped seeing GE as an adversary and have started realizing the company can help them make a difference, Kevin Skillern, a managing director at GE Energy Financial Services, said in a keynote speech at a Thomson Reuters conference called “Financing the Cleantech Vision” in Palo Alto on Wednesday.
In spite of the recession, Skillern assured the audience that the long-term business opportunity for cleantech is still there, though it will require “a strong stomach and a lot of patience” to cash in on it. He also called climate change “one of, if not the biggest, societal challenges of our time” and said technology was an essential part of the solution.
Green Jobs: So Attractive, So Few, So Far

The prospect of green jobs has proven very attractive to Californian job seekers. According to a survey released this week by the Vote Solar Initiative, a solar advocacy group, more than 5,400 people are participating in solar job training programs this year in the state.
“It is clear that Californians of different economic and educational backgrounds are all looking to solar to provide much-needed career opportunities, and the state’s training institutions have stepped up to meet that rising demand,” said Claudia Eyzaguirre, the author of the report, in a press release.
But it’s not clear whether the state will have enough jobs to support these trainees. Part of that will depend on the kinds of jobs they are training for.
Graphene Emerging as the Miracle Material of the New Millenium

Move over, silicon: graphene is ready for its closeup. Discovered just a few years ago, graphene is a sheet of graphite the thickness of just one atom. It can be processed like silicon to make electronic devices, which makes it easier to manipulate than the current “it” material, carbon nanotubes. Without the breakdown problems that beset silicon at the nanoscale, graphene is bringing the dream of a molecule-sized computer closer to reality.
