Bush is anti-environment

3 comments

No surprises here.

White House officials last December sought to stop the Environmental
Protection Agency from submitting a proposed rule that would limit
greenhouse-gas emissions from new vehicles.

The proposed rule was EPA's response to an April 2007 Supreme Court
ruling that the agency had violated the Clean Air Act by refusing to
take up the issue of regulating automobile emissions that contribute to
global warming.

Man-made tornadoes as power source?

1 comments

A
Canadian engineer has a plan to extract
energy from a man-made tornado.  It all depends on heating the air near the surface so that it is much warmer than the air above.

Convective air currents are only useful if they can be
channeled in some way.

Unwanted Content

1 comments

There seems to be lots of content on this site that gets posted, and it has nothing to do with what the site is about. 

We don't care if you're single.  We don't care if you're mad at your best friend because she stole your date for the prom.

Most people don't know about the Flagging feature here on Greenopolis.  At the bottom of each post, there is a link that says "Flag as Offensive".  When you click on this link, you can choose why the content is offensive, and one of the options is "Off-Topic".

Virtualization

0 comments

The hottest trend right now in green computing centers around virtualization.  For those not familiar with the topic, virtualization allows you to running multiple operating systems on a single piece of hardware.  The benefit to this is that you maximize resource utilization on a server while lowering power consumption and reducing cooling costs.

VMWare is perhaps the best-known vendor providing virtualization software.  However, Microsoft is in the game as well, and Xen, a new vendor on the scene, has some pretty promising solutions, if a bit immature.

Nano-battery Revolution

1 comments

Researchers are developing new technology that  uses nano-technology to drastically increase the lifespan of batteries.

The key innovation involves using silicon nanowires instead of the usual carbon to store energy in a lithium-ion battery's anode.  Silicon has more than 10 times as much charge capacity as carbon. With this innovation, you could theoretically be running your laptop for 20 to 40 hours straight rather than the typical two to four hours. An electric car could go 400 miles on a charge rather than 40 miles.

Dancing On Hype?

2 comments

I was just reading about how there is a big push for environment awareness at this year's Sundance Film Festival.

Car manufacturers are jumping on the ride, hoping to get free publicity for their hybrid cars and technology that is largely in prototype, and will never see the public.

How much of this could be considered a hijacking by corporate America as a giant PR campaign?  Will this be just like every other election cycle where energy policy is brought to the fore and then quickly dropped once someone is elected?
