Eco-friendly city planned in China

“If countries like China don’t cut their carbon emissions drastically then it doesn’t matter what the rest of us do.”

I’m beginning to lose count of how many times I’ve heard that argument, or a variation of it. There is some truth to it, but that doesn’t make it any less disheartening to hear it used repeatedly as an excuse for inaction across Europe.

Good news from China this week then, with the announcement that plans for the world’s first carbon-neutral city have been unveiled.

The city of Dongtan will house a quarter of a million residents, and aims to provide power for all of them through solar, wind and biofuel power.

The first phase is due to be completed by 2010, and four other Chinese cities are putting similar plans into place.

Coverage of the proposed city has been positive but sceptical; we’re probably all used to hearing of grand eco-plans that never come to fruition, or fall short of the goals they are aiming for. Let’s hope that’s not the case here and that Dongtan inspires carbon-neutral cities worldwide. Apparently London Mayor Ken Livingstone has already said he would like to build a similar eco-zone along the river Thames.

Sustainable living courses with the low-impact living initiative

I try to live sustainably. I shop locally, don’t drive, go for environmentally-friendly and fairtrade choices when I can – just like most of the people reading this probably do.

But I know that I don’t actually have any living skills. If there was a natural (or man-made) disaster, I’d be lucky if I could cobble myself together a basic shelter, let alone sort out a radio or any food and fuel. Without companies or more knowledgeable people to make things for me, I’d be completely stuck.

That’s one of the reasons I was interested to hear about the low-impact living initiative. The group aim to help people lower the impact of their everyday lives, and run regular courses, as well as selling books and manufacturing products via their website.

Their one-day courses cover crafts such as rag-making and keeping chickens, while over the course of a weekend you can learn about skills such as low-impact smallholding and how to make biodiesel.

Courses run throughout the year, and you book online, with discounts for students and people who are out of work or on a low wage.

Is global cooling the answer to global warming?

Though increasing effort goes into combating the worldwide effects of pollution, will it be enough? And if not, then what? Roger Angel, University of Arizona Regents Professor and the Steward Observatory Mirror Laboratory’s director, suggests not interposing a great big sci-fi type mirror between us and the sun, but trillions of tiny “flyers”, in a glistering silver shield to break up the sun’s rays and disperse them (or better still, in some future generation, absorb that power and turn it into something usable by man). Flyers are transparent sheets 60cm in diameter and vastly thinner than a human hair, each weighing about a gram, which would be launched in a cloud encircling the earth, with a diameter of about 100,000 kilometers. If we start now, and launch one every five minutes, by 2017 it would be entirely in place. Or, Angel says, we could just do a better job of cleaning up the place now. [GT]

Intelliplug makes energy saving easy

Plug your computer into the Intelliplug master socket, and plug your, for example, monitor and printer into the slave sockets. Then when you turn off the computer, the Intelliplug automatically cuts power to the monitor and printer. Recommended by the Energy Saving Trust. £17. [GT]

Flisom says thin film solar to wipe out fossil power

New thin film solar, so lightweight and flexible it can be stuck to the side of buildings (or clothing for that matter) is about to sweep the marketplace and provide power at half the cost of the current fossil-fuel generated juice, says Anil Sethi, the chief executive of the Swiss start-up company Flisom.  The thin film will be manufactured in rolls like cellophane tape, and within a decade, hit only 50p per watt – which is the tipping point.  The power is at about £2 per watt now, so it’s getting close.  It’ll also mean mobiles, mp3 players, etc, will carry their own power-generation sources so those nasty cables will be a thing of the past.  [GT]
