I think there's a NASA report on the best ones to use. You'll need water and power to keep them lit 24/7. That works for industrialized countries but maybe less well for the third world.

Re: Dr. Park to speak at UW-Madison

But why is it again that this is still being pursued here as this is more appropriate to be discussed in general? I'm sure msimon will move it if he sees fit.

Re: Dr. Park to speak at UW-Madison

Today emissions are 35 bn tonnes CO2. That's from roughly 2bn industrialized inhabitants. So suppose 10bn people emit 5 times that. At the moment CO2 is rising about 2.8 ppm per year.

Re: Dr. Park to speak at UW-Madison

I'm getting crotchety in my old age. I object to people who object to plant food. I like plants. Do you have any idea what the minimum amount of plant food in the atmosphere should be? Below 100 PPM the plants suffer Maximum levels for growth are about 1000-1200 PPM Plants will grow in much higher ...

The Islamic religion is not at war with you. Since there hasn't been a Caliph in a while, there's no practical way for the entire religion to be at war. Osama Bin Laden, on the other hand, declared war on America in 1996: Declaration of War against the Americans Occupying the Land of the Two Holy P...
