“The pressurised steel tank is filled with around 20 litres of nitrogen, plus some hydraulic fluid. Much like a Prius, Hybrid Air vehicles recover energy every time the driver brakes or decelerates. But instead of using this kinetic energy to charge a battery – as electric hybrids do – the Hybrid Air system has a reversible hydraulic pump that compresses the nitrogen in the tank and then unleashes it the next time the driver pumps the accelerator.
“It’s mainly a …” Yarce searches for the word, “a syringe. The nitrogen compresses or decompresses and actually pushes the oil and the hydraulic components to transform this energy into a force that makes the vehicle move forwards. It’s as simple as that.”“

“The idea of using urban agriculture as the means for revitalizing a community is pretty innovative in and of itself, but activist and developer Mansfield Frazier has plans for a first-ever addition to the vineyards: a biocellar. We mentioned this in passing in the first post, but as the biocellar concept has received more attention recently, I got intrigued by this plan to turn blighted houses into underground greenhouses.
That, essentially, sums up the idea: abandoned houses that are past any hope of renovation are demolished, but the basements are kept intact. With some additional support and a greenhouse-type structure built over the basement, an urban farmer/gardener now has a space that maintains constant temperature appropriate for growing crops… or even maintaining small ecosystems.”

Researchers at the Massachusetts Institute of Technology have figured out how to track trash. They are doing this to get a better sense of people’s disposal habits, which they hope will improve recycling efforts.

Every country should be so lucky as to have Sweden’s problem: It doesn’t produce enough garbage.
As reported by Public Radio International (26.06.12), Sweden has a remarkably effective recycling program. Only 4 percent of the country’s waste ends up in landfills, with the other 96 percent being reused in some way. There is one problem with that, however: The country has incinerators that burn waste to create heat (a must-have in the region) and electricity. And too little waste means not enough fuel for those fires…

Some stuff takes a long time, folks…
Act wise. We all share this same planet.
It’ll come back to haunt you.

“Short on space but hankering for some fresh vegetables? The $70,000 Agri-Cube might be the answer to your problems. Developed by Japan’s Daiwa House Industry, the parking-space-sized cube can grow leafy greens and root vegetables like turnips and radishes.
The self-contained system comes with a water recycling system and adjustable fluorescent lighting (instead of sunlight) to nourish the plants. Under the right conditions, the cube can grow up to 10,000 heads of lettuce per year—all for approximately 45 cents a vegetable, when electricity costs are taken into account, according DigInfo.
The Agri-Cube’s high price tag gives it limited appeal to the average consumer, but we imagine that restaurants might be big customers, especially since certain restaurants are already experimenting with rooftop hydroponic farming. For restaurants that lack roof access but have a bit of outdoor space, this could be the next best thing.”

“Designer Garth Britzman of Lincoln, Nebraska used recycled bottles filled with colored water to create stunning topographical shade canopy for a vehicle. I love how the natural shape of the plastic bottles makes the pooled water look like leaves. See more over on Behance. (viamy amp goes to 11)”

“Amid all the controversy over genetically-modified (GM) crops and their pesticides and herbicides decimating bee populations all around the world, biotechnology behemoth Monsanto has decided to buy out one of the major international firms devoted to studying and protecting bees. According to a company announcement, Beeologics handed over the reins to Monsanto back on September 28, 2011, which means the gene-manipulating giant will now be able to control the flow of information and products coming from Beeologics for colony collapse disorder (CCD).”
