It appears that the reign of Big Coal may be coming to an end. TreeHugger reports from a new EarthPolicy release regarding a timeline of events for the Coal Industry. This last entry is particular heartening.
11 March 2008 – Representatives Henry Waxman (D-CA) and Edward Markey (D-MA) introduce a bill that would block the EPA and states from issuing permits to new coal-fired power plants that lack state-of-the-art carbon capture and storage technology. Since this technology is at least a decade away from commercial viability, if this bill passes it would essentially place a near-term moratorium on new coal-fired power plants.
It’s time to harness the world’s virtually inexhaustible supply of solar energy and start building a brighter future.
Is there really anything else that needs to be said? Great article by Steve Heckeroth over at MotherEarthNews.com. Here’s a single portion serving for you.
We know that relying on coal, oil and natural gas threatens our future with toxic pollution, global climate change and social unrest caused by diminishing fuel supplies. Instead of relying on unsustainable fossil fuels, we must transform our economy and learn to thrive on the planet’s abundant supply of renewable energy.
I have been studying our energy options for more than 30 years, and I am absolutely convinced that our best and easiest option is solar energy, which is virtually inexhaustable. Most importantly, if we choose solar we don’t have to wait for a new technology to save us. We already have the technology and energy resources we need to build a sustainable, solar-electric economy that can cure our addiction to oil, stabilize the climate and maintain our standard of living, all at the same time. It is well past time to start seriously harnessing solar energy.
Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don’t scale down well—there’s too much friction in the gearbox and other components. “With rotary power, there’s nothing out there that generates under 50 watts,” Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington’s Tacoma Narrows Bridge (aka Galloping Gertie).
Frayne’s device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes. “Kerosene is smoky and it’s a fire hazard,” says Peter Haas, founder of the Appropriate Infrastructure Development Group, which helps people in developing countries to get environmentally sound access to clean water, sanitation and energy. “If Shawn’s innovation breaks, locals can fix it. If a solar panel breaks, the family is out a panel.”
Frayne hopes to help fund third-world distribution of his Windbelt with revenue from first-world applications—such as replacing the batteries used to power temperature and humidity sensors in buildings. “There’s not a huge amount of innovation being done for people making $2 to $4 per day,” Haas says. “Shawn’s work is definitely needed.”
