Earth Day in Singapore 2006
According to the Earth Day 2006 calendar, Singapore is marking Earth Day 2006 with a close-up of avian influenza, otherwise known as bird-flu. Somewhat sobering, eh? But perhaps appropriate.

But all is not lost. There is also an Earth Day picnic with the Nature Society at the Botanic Gardens. Actually, they began marking earth day since 12 March. Good on them. The Su
bstation, Singapore's first and most beloved independent contemporary arts centre, is celebrating Earth Day for the Asian elephants. If you are driving, you can have your car cleaned the eco-friendly way at $8 per car whilst you're attending the talk and proceeds go to "Friends of the Asian Elephant" - to quote Wild Singapore. Go visit the website for the lowdown.

Of wind turbines and birds
From Gizmodo: quietrevolution's elegant vertical-axis wind turbine is, as its name suggests, quiet but can be made avante-garde with the help of LEDs. A bit of programing and you have images, perhaps even moving ones. Sorry, but ecodes is into peace and quiet...and this applies to the other senses as well as the ears.

And then there's this: Magenn Power supplies an inflatable turbine based on the magnus effect. Among other claims - more efficient, cheaper, lada, lada, lada - it is supposed to be safer for the birds.

Talking about which, if you are worried about wind turbines and birds, you can get the lowdown at treehugger. The short of it is: "small blades, low surface area, lots of dead birds possible; very big blades, with large surface area exposed to wind, very few dead birds." Go read it yourself.
