A new twist on wind turbines. This young inventor wanted a super cheap method for generating power on a micro scale and has achieved this by using a technique known as flutter. Wind flutter occurs when wind flows across a high tension strip causing it to flutter. The flutter effect is converted to energy at the end simply by placing the high tension strip between some coils.
Here is a look at a new prototype car by Venturi that they tout as an ‘autonomous energy vehicle’. Autonomous in the sense that the batteries will allow it to cover 30 miles on a full charge, and the solar panels and wind gust chargers will recharge the batteries. If you happen to live in London and the greyness isn’t giving your batteries the loving they need you can always plug it into AC.
First production runs are limited to 200 so I would imagine the $30,000 price tag won’t be high enough to scare off those fast adopters whose carbon debt won’t let them sleep at night.
I stumbled across a site today with some excellent graphical representations of the world. I enjoy seeing graphical presentations of complex data, presented in novel, and extrelely pleasing to the eye, ways.
– Glass Half Empty – the coming water wars
The Swedish Minister for sustainable development (hey do all countries have one of these?) came out and said that they aim to be fossil-fuel free by 2020, therefore being the first country to step up to the plate in-front of one hell of a pitcher, oil and the big oil companies.
What does this mean? In essence Sweeden wants to become energy sustainable, complete reliance on renewable energy. Yep. 100%. Calls have gone out to experts in the alternatives, wind, solar, tidal, biomass, hydrogen.

The media site ChangeThis is working to spread new thoughts and ideas to a wider audience. There are a number of interesting manifestos and I found the beyond sustainability one worth a mention.
It tackles the fundamental concepts of sustainability from the very necessary position of redefining the entire concept and looking at realising humans possibilities.
As a society, we are addicted to solving our problems through a reductionist frame. When
we confront problems in the world, we chop them into small pieces and give each piece to a
specialist familiar with that chunk. Over time, as we have done this more and more, society’s
competence to address the complex, messy problems we confront has diminished.
Unsustainability is just such a messy problem. Sustainability is a holistic concept that takes
an equally holistic stance to attain. Reductionist solutions will not suffice.
John Errenfeld goes on to discuss how to tackle the root causes rather than the symptoms. Fundamental changes in the way we think and the way we live our lives. Well worth a read.
Here are a couple of great pics to advertise the enormity of the problem facing us all. I think I may stop bothering to slow global warming and concentrate on learning boat building.
