Inspirational and good news.
Here’s some good news for all you chocolate lovers out there: a chocolate byproduct can provide fuel!
North western English firm Ecotec has taken waste from the chocolate manufacturing process, turned it into bio-ethanol and mixed it with vegetable oil to produce biodiesel.
Some biofuels have come under fire for either diverting much-needed food crops or leading to massive deforestation as land is cleared to grow crops specially for biofuel production.
I love bikes, and I love it when places embrace the wonderful invetion, Portland Oregon has arguably done the best job of bike-loving in North America. The International Herald Tribune has a really nice article about what has made Portland the mecca of bike culture in North America.
Mia Birk, a former city employee who helped lead Portland’s efforts to expand cycling in the 1990s, said the original goals were rooted in environmental and public health, not the economy.
“That wasn’t our driving force,” Birk said. “But it has been a result, and we’re comfortable saying it is a positive result.”
Birk now helps run a consulting firm, Alta Planning and Design, which advises other cities on how to become more bicycle-friendly. In a report for the City of Portland last year, the firm estimated that 600 to 800 people worked in the cycling industry in some form. A decade earlier, Birk said in an interview, the number would have been more like 200 and made up almost entirely of employees at retail bike stores.
Thanks Aidan!
This technology represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.Terra Preta Soils a process for Carbon Negative Bio fuels, massive Carbon sequestration, 1/3 Lower CH4 & N2O soil emissions, and 3X Fertility Too.
After many years of reviewing solutions to anthropogenic global warming (AGW) I believe this technology can manage Carbon for the greatest collective benefit at the lowest economic price, on vast scales. It just needs to be seen by ethical globally minded companies.
Could you please consider looking for a champion for this orphaned Terra Preta Carbon Soil Technology?

The blistering sun that shines down on the people down under will be lighting more than jsut heir sky. A small town in Australia’s north is going to make a 10-megawatt solar power plant that uses the power of the sun, and not in any regular way. Indeed, to make themselves unique, the town will be using solar energy by reflecting 8,000 mirrors at some graphite, then pour water on the stone, thus making steam. The steam will then power turbines; as a result, the power plant can run all day and night.
The Queensland state government said on Sunday it would build the A$7 million ($6.5 million), 10-megawatt power station as part of a push to make Cloncurry one of the first towns to rely on solar power alone.
“The town of Cloncurry has long claimed the title of having recorded Australia’s hottest day — 53 degrees (Celsius) in the shade in 1889, so I reckon we’re on a winner,” Queensland Premier Anna Bligh was quoted as saying by Australian Associated Press.
Solar thermal power differs from photovoltaic panels that make power directly.
Conventional wind turbines don’t scale down well—there’s too much friction in the gearbox and other components. So poor, remote communities don’t have any way to harness the power of the wind. Till 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. 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. Popular mechanics has a good article about the device here.
