Saltwater-loving plants could open up half a million square miles of previously unusable territory for energy crops, helping settle the heated food-versus-fuel debate, which nearly derailed biofuel progress last year.
By increasing the world’s irrigated acreage by 50 percent, saltwater crops could provide a no-guilt source of biomass for alt fuel makers and tone down the rhetoric of U.N. officials worried about food prices, one of whom called the conversion of arable land to biofuel crops “a crime against humanity.”
While growing crops in saltwater has been on the fringes of horticulture for decades, the new demand for alternative energy has pushed the idea onto the pages of the nation’s most prestigious scientific journal and drawn the attention of NASA scientists.
Citing the work of Robert Glenn, a plant biologist at the University of Arizona, two biologists argue in this week’s Science that “the increasing demand for agricultural products and the spread of salinity now make this concept worth serious consideration and investment.”

If you felt that the atmosphere in the new hip Club Watt was somehow electric, you would be right: Watt has a new type of dance floor that harvests the energy generated by jumps and gyrations and transforms it into electricity. It is one of a handful of energy-generating floors in the world, most still experimental.
With its human engineering, Watt partly powers itself: The better the music, the more people dance, the more electricity comes out of the floor.

You can buy a house with a frozen credit market–you just have to save up the cash purchase price first. Novel approach, I realize, but there you have it. Believe it or not, people used to do this fairly frequently.
You can still manufacture complex products. But, rather than getting a loan to buy the capital equipement, materials, and pay the labor, then give it to the customer, get them to pay you, and repay the loan, now you need to 1) get the customer to pay you, or 2) maintain enough cash reserves to carry this cost until payment. This means that either the customer or the producer needs to save up the money for the end product first, rather than pay later. This also has a dramatic impact on business models–the ‘get big first, then figure out how to profit’ model advanced by Amazon.com and others simply doesn’t work. All these changes really shake up the rate of throughput while System B reverts back to System A. […]
The next two or three years of focus, budget, and effort fixing the financial crisis are two or three years where we aren’t using oru rapidly dwindling supply of high net-energy surplus oil and gas to invest in a renewble energy infrastructure or to restructure our economy away from the demand for continual growth. In fact, the short-term drop (or at least fear thereof) in commodity consumption is likely to depress prices enough that there’s no financial incentive to even invest in keeping production steady.
We’re setting ourselves up for the perfect storm. Resurgent global demand for energy will hit just about the time that our energy supplies (especially our net energy supplies) begin to rapidly decline. As I’ve said in jest many times on this blog, the Mayan prophecies about 2012 may not be that far off the mark–at least as far as timing is concerned.
Charley and Chuck Greenwood, a father-son combo, think they know the secret to the future of cars: rowing.
And they founded their company HumanCar to prove that human energy, not biofuels, is the gasoline of the future. Their Imagine_PS car seats up to four in a low-slung chassis; the passengers get to help row the lightweight car.
Think of it as an ergonomic, efficient and sneaker-saving Flintstone’s car for an oil-free future. The front two ‘drivers’ get to steer, which is done with a talented and coordinated lean.
“Body steering comes from the hips,” CEO Chuck said. “It’s just like a properly performed ski turn.”
But revolutionizing steering is not the point of these Oregon entrepreneurs. “It’s about thinking about days per life versus miles per gallon,” CEO Chuck Greenwood said.
When powered by four people rowing, the car will go about as fast as the ‘drivers’ would on bicycles, on average.
Back in August the news broke that Hyperion Power Generation had found someone to buy the first of its portable nuclear power units. While I’m sure many doubts about this technology remain in people’s minds, a recent interview with Hyperion CEO John Deal sheds some more light on the whole notion of portable nuclear power. Here are some highlights from Techrockies.

While on that flight, Brand came up with a solution: to publish a magazine in the vein of the LL Bean catalog-which he’d always admired for its immense practicality-that would blend liberal social values with emerging ideas about ‘appropriate technology’ and ‘whole-systems thinking.’ He decided to run NASA’s photograph of the planet on the cover and to call the publication the Whole Earth Catalog (WEC). The first WEC, published in July 1968, was a six-page mimeograph that began with Brand’s now-legendary statement of purpose: ‘We are as gods and we might as well get good at it.’
The WEC lasted four years (along with some special editions since). During that time, the magazine published a flood of articles about species preservation, organic farming, and alternative energy-but it was also a resource for ‘tools’ as wide ranging as Buddhist economics, nanotechnology, and a manure-powered generator. Comprehensive in this way, the WEC was a catalyst, helping transform a set of disparate individualists into a potent community. As Lloyd Kahn, the catalog’s shelter editor, says, ‘The beatniks had a negative, existential vibe. They weren’t into sharing. But the hippies came along and wanted to share everything. Whatever they discovered, they just wanted to broadcast. The WEC was the very best example of this.’
It is now 40 years later and the WEC’s avalanche of influence continues to flow. Cyberculture, the blogosphere, companies like Apple and Patagonia, websites like Craigslist and worldchanging.org, sustainable building, ethical business practices, and the gamut of alternative-energy industries were all shaped by its pages. Its ecological legacy spans everything from new cattle-grazing techniques to major environ?mental legislation. What follows is an oral history, compiled from 30 hours of interviews, that takes a look at the Whole Earth Effect-the long-lasting impact of this short-lived journal, as told by the people directly in its path.
The Whole Earth Catalog was well before my time, but obviously Technoccult owes a big debt to it.

Home-brewed biodiesel may be ready to move from your neighbor’s garage to prime time. No longer is the practice limited to a few mechanically inclined hippies with old converted electric water heaters. Now anyone can order up their own bio-brew kit online.
“We are testing some products now to make sure they work at the level of quality our customers expect,” said Go Green Home Stores spokesman Dennis Healy. “We’re really looking forward to having these products in our store.”
And Go Green’s interest in mass-marketing a processor comes on the heels of a decision earlier this year by Northern Tool, the Sears of professional-grade tools, to put biodiesel processors for home brewers in its catalog, for $3,000 to $13,500.
The Collective Biodiesel Project estimates that home brewers, who filter used vegetable oil from restaurants and then mix it with lye and methanol to create their own biodiesel, produced 450 million gallons of fuel last year. Some brewers say they got tired of waiting for alternatives to petroleum to come from big biz and set out to change their own habits.
Google may take its battle for global domination to the high seas with the launch of its own ‘computer navy’.
The company is considering deploying the supercomputers necessary to operate its internet search engines on barges anchored up to seven miles (11km) offshore.
The ‘water-based data centres’ would use wave energy to power and cool their computers, reducing Google’s costs. Their offshore status would also mean the company would no longer have to pay property taxes on its data centres, which are sited across the world, including in Britain.

She has developed a simple, cheap way of producing solar cells in a pizza oven that could eventually bring power and light to the 2 billion people in the world who lack electricity. […]
Ms Kuepper realised a new approach would be needed if affordable cells were to be made on site in poorer countries: “What started off as a brainstorming session has resulted in the iJET cell concept that uses low-cost and low-temperature processes, such as ink-jet printing and pizza ovens, to manufacture solar cells.”
While it could take five years to commercialise the patented technology, providing renewable energy to homes in some of the least developed countries would enable people to “read at night, keep informed about the world through radio and television and refrigerate life-saving vaccines”. And it would also help reduce greenhouse gas emissions.
In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.
Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today’s announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
Requiring nothing but abundant, non-toxic natural materials, this discovery could unlock the most potent, carbon-free energy source of all: the sun. “This is the nirvana of what we’ve been talking about for years,” said MIT’s Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and senior author of a paper describing the work in the July 31 issue of Science. “Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon.”
