A Permaculture Garden Pool

Permaculture is the idea of contained sustainable agriculture that requires no external inputs – all energy and required input is generated by the permaculture system. Some enterprising people have turned their backyard swimming pool into a permaculture setup that is based around aquaculture.

Watch the video for some neat views and an explanation of the system. You can also find out more from the garden pool website.

The garden pool combines:

solar power – harnessing and storing the sun’s energy
water conservation – using less water and recycling waste water
poultry farming – raising chickens
aquaculture – raising tilapia fish
hydroponic gardening – growing fruits, veggies, & herbs without soil
organic horticulture – using natural methods to control garden pests
aquaponics – the symbiotic cultivation of produce and fish in a recirculating hydroponic environment.
biofiltration – natural water filtration method using biochemistry and duckweed.

Whisky Biofuel from Scotland

A lot of people enjoy Scottish whisky and now their cars can also enjoy the same beverage. Scottish scientists have figured out how to use the byproducts of whisky production as a source for biofuel.

Copious quantities of both waste products are produced by the £4bn whisky industry each year, and the scientists say there is real potential for the biofuel, to be available at local garage forecourts alongside traditional fuels. It can be used in conventional cars without adapting their engines. The team also said it could be used to fuel planes and as the basis for chemicals such as acetone, an important solvent.

The new method developed by the team produces butanol, which gives 30% more power output than the traditional biofuel ethanol. It is based on a 100-year-old process that was originally developed to produce butanol and acetone by fermenting sugar. The team has adapted this to use whiskey by-products as a starting point and has filed for a patent to cover the new method. It plans to create a spin-out company to commercialise the invention.

Earth Friendly Beers

Beer is good and here at Things Are Good we do drink a lot of it. We also know that beer can be pretty intensive in water consumption and other resoruces, so I’m happy to share the news of eco-friendly brewers.

New Belgium
Located in Fort Collins, CO, right up the road from me, New Belgium may just be the pinnacle of eco-friendly beer brewing. In 1999, New Belgium became the largest private consumer of wind-powered electricity, and is an employee-owned business that prides itself on its environmental stewardship, adhering to the following creeds:

1. Lovingly care for the planet that sustains us.
2. Honor natural resources by closing the loops between waste and input.
3. Minimize the environmental impact of shipping our beer.
4. Reduce our dependence on coal-fired electricity.
5. Protect our precious Rocky Mountain water resources.
6. Focus our efforts on conservation and efficiency.
7. Support innovative technology.
8. Model joyful environmentalism through our commitment to relationships, continuous improvement, and the camaraderie and cheer of beer

They take full advantage of the more than 360 days of sunshine in Fort Collins by using UV blocking windows, sun-tubes, and light shelves; they use evaporative coolers, which condition their 55,000 square foot packaging hall with no compressors; and at their public events like their philanthropic bike festival, Tour de Fat, New Belgium celebrates bicycling as a viable form of alternative transport while a solar-powered stage provides sound for the day

We’ve looked at one of these breweries, Steam Whistle, before.

Cadbury Goes Fair Trade

If you’ll excuse for a moment while I pander to corporate interests, I think it’s worth noting that Cadbury’s Dairy Milk chocolate bar will now be made from certified fair trade cocoa. This is great to hear, because this is a huge product from a huge company, and it’s another big step towards a world in which consumers have no excuse not to know about fair trade.

Cadbury and the Fairtrade Foundation today announced plans to achieve Fairtrade certification for Cadbury Dairy Milk, the nation’s top selling chocolate bar, by end of Summer 2009. This groundbreaking move will result in the tripling of sales of cocoa under Fairtrade terms for cocoa farmers in Ghana, both increasing Fairtrade cocoa sales for existing certified farming groups, as well as opening up new opportunities for thousands more farmers to benefit from the Fairtrade system.

The press release doesn’t indicate which countries the change will take effect in, but the UK and Canada are definitely included.

Keeping it Cool Without Air Conditioning

In really hot countries air conditioning in buildings might seem like a necessity; however, it is possible to design buildings that stay cool in the heat without even using electricity. In Burkina Faso there is a school that was specially designed to stay nice and cool by manipulating airflows.

There’s not much electricity to go around, Kéré says. “So there is no air-conditioning. It’s too expensive for a country like Burkina Faso.”

So when he designed this secondary school for Dano in his native land, he built it with innovative, elegant, distinctive and yet simply constructed split-level roofing and ceiling structures that funnel warm air up and out of the buildings.

Tall window slats that can be adjusted control both light and heat. Three to a room, they pull air into the classroom. Heat rises.
To use that movement of air, a series of narrow “chimney” gaps between the convex wave shapes in the highly insulating concrete and brick ceiling pulls the hot air up and out the roof.
