Farming plankton, sending solar panels into orbit, remodeling hydrogen — for the latest wave of entrepreneurs suggesting easier ways out of climate change, it’s all in a day’s pitching.
Beyond grabbing headlines, such notions are attracting serious scientific attention and venture funding from investors who at least until the collapse of Lehman Brothers lent credibility to high-risk investment propositions.
Some plans seek radical alternatives to fossil fuels. Other businesses are dreaming of geoengineering — planning to tweak the earth’s climate by removing heat-trapping carbon dioxide or reflecting sunlight into space.
Among new energy fixes presented to Reuters in recent days is US-based BlackLight Power.
The company says it may have tapped the energy that cosmologists have struggled to explain, called dark matter, which fills the universe. The concept involves shifting electrons in hydrogen molecules — obtained cheaply from water — into a lower orbit, releasing energy in the process.
“It represents a boundless form of new primary energy,” founder Randell Mills said in a phone interview.
“I think it’s going to replace all forms of fuel in the world,” he said.
Britain’s top science academy, the Royal Society, this week urged more funds be channelled into research on geoengineering, but for some climate commentators the unproven, technical solutions smack of society’s craving for pain-free get-outs.
They said politicians might prefer to feed that habit rather than face tough choices in redressing global warming.
Greenpeace chief scientist Doug Parr said geoengineering projects would be seized upon by polluters as a quick fix, and the former climate change adviser to oil firm BP said they were simplistic.
“People are being naive ... looking for a technological fix,” said Chris Mottershead, who is now head of research and innovation at King’s College London.
“Anything of the necessary scale will have its own unintended consequences, even if they are not recognized at the moment,” he said.
Since 1991, BlackLight’s founder said his company has raised US$60 million from private investors who have included the former chairman of Morgan Stanley, Dick Fisher and the bank’s now retired head of energy. Mills says his goal is to produce a 250 kilowatt prototype by the end of next year.
The estimated capital cost of the energy at US$500/KW would be less than coal power, one of the cheapest forms of energy now. Several utilities have bought licences, in case it works.
Last month New Jersey-based Rowan University engineers said the BlackLight process in the lab had produced heat some 1.6-6.5 times beyond levels that can be easily explained.
“It does portend some type of novel energy source,” said Peter Jansson, associate engineering professor at Rowan.
In another energy fix, California-based Solaren wants to launch solar panels into orbit to send back radio waves which can generate electricity back on Earth — and benefit from the sun shining 24 hours a day in space.
“It’s not like a laser or a bug zapper or anything like that,” founder and CEO Gary Spirnak said. “I think this could be like any other large power source, 20-25 percent of the world’s electricity, 30 or 40 years out.”
Solaren aims to produce electricity from a 200 megawatt prototype by 2016 at a cost of several billions of dollars per plant.
