San Francisco cooks up plans for a green utopia; Toyota leaks details of a bigger, faster Prius; and the world’s best — and possibly most expensive — lightbulb. Happy Tuesday from EcoTech Daily.

Next-gen Prius Bigger, More Powerful: The third-generation Toyota Prius isn’t due to be revealed until next January’s Detroit Auto Show, but details are already beginning to filter through to the press. The big story is just that: the next Prius is said to be up to 4 inches longer than its predecessor, and equipped with a significantly more robust powerplant. Also on Toyota’s punch list: reduced weight and more electric driving range. Plug-in driveway charging will wait until at least 2010. (Auto Observer)

Evolux’s EarthLED Light Bulb: We reviewed EarthLED’s product line on our sister site, Lighter Footstep, back in August. Now EarthLEd is out with what they are calling the “world’s most advance light bulb.” The good: magnificent engineering, pure LED light, and a miserly 13 watts produces as many lumens as a 100 watt incandescent bulb. The bad: it’s $80. That’s not just bad — it’s ugly. (Good Clean Tech)

Cheatsheet: Perfluorochemicals (PFCs): We loved last week’s “cheatsheet” on Bisphenol A from the folks at Enviroblog. Now they’re back with another well-organized cheatsheet summarizing the issues which surround Perfluorinated chemicals (PFCs). Well worth a read if you come into contact with Teflon, Scotchgard, Stainmaster, or Gore-Tex. (Enviroblog)

Technological Breakthrough In Fight To Cut Greenhouse Gases: Newcastle University scientists have found an efficient new way to scrub carbon dioxide and thus reduce greenhouse emissions. The method uses an active aluminum catalyst and an epoxide. Bonus: the resulting reaction yields cyclic carbonate compounds, which can be used to make gasoline-burning engines more efficient.

The Most Sustainable Future Community in the US: Mirror, mirror, on the wall — who’s the most sustainable of all? San Francisco’s Treasure Island, if the city has a say in things. The SF Board of Supervisors plans to transform the 400 acre artificial island into a model green community, featuring high density housing, streets angled for the best shot at solar energy, and a full slate of eco-attractions. The first residents could move in by 2013. (PlanetSave)
