“Energy Secretary Steven Chu stunned the audience at a London scientific conference Tuesday with a radical but simple proposal to combat global warming: Paint all the roofs of all the buildings in the world white.
If we did so, the Nobel Prize-winning physicist said, and if we also made sure the world’s roads and sidewalks were light-colored, it would have the same effect on global warming as taking all the cars in the world off the world’s roads for 11 years.
The idea is to harness the “albedo effect” — the theory that a reflective planet warms up less as heat from the sun is bounced back into space.”
correct me if i’m wrong but the problem, though, is that the heat energy bouncing off all this white paint won’t just float off into space; most of it will stay in our atmosphere anyway.
Sure, but more energy directed upward would still increase the energy that escapes the planet, even if only by a little bit. But his numbers sound greatly exaggerated. It seems horribly impractical.
Frankly, I think green roofs are a much better solution. While they wouldn’t reflect as much energy skyward as white paint, they still absorb the sunlight energy without turning it into heat, they help with building cooling costs, absorb carbon dioxide (which is a main creator of the greenhouse effect), emit oxygen, and control rain runoff.
Paint all the roofs black and use the heat to generate electricity sure why not?
Every employee is given virtual tokens — say, 100 a week, — that they can attach to e-mail they write. If you really want someone to read a message now, you attach a lot of tokens, and the message pops up higher in your correspondent’s Outlook inbox. Reeves figured this would encourage people to send less e-mail: Those who are parsimonious would wind up with lots of tokens, which means when they really have something to say, they can load it up with tokens and make sure it’ll get through. Sure enough, that’s what happened. When a work group at IBM tried out Attent, messages with 20 tokens attached were 52 percent more likely to be quickly opened than normal. E-mail overload ceased to be a problem.
I love this idea. This would make it way easier to tell which emails were worth reading. They should also make the number of tokens required dependent on the number of recipients. I bet people would be really careful with the “Reply all” button then!
Wow, this is a great idea - lets get a google mail addon please!!!
My blog is hosted by tumblr. So far I haven’t had much reason to dislike it. However, they have introduced this thing called tumblarity which is basically a popularity contest for all the people who have blogs hosted by tumblr.
I personally think it is a cheap ploy to incentivize people (who care about such idiotic things) to post more. Methinks Tumlbr is trying to make their stats look better for their investors. Anyway, it’s complete rubbish and pointless and from what I read on my dashboard it seems like other bloggers agree with this point of view.
