I totally agree with you on that. As soon as they figure out how to do
something like this, they will force us to become dependent on it and muck
up the planet.

That's really cool, but I don't think we'd want to eliminate lightning 
completely. It does help produce ozone, which in turn protects us from harmful 
radiation from space. When it comes to Nature, one well-intentioned action can 
often have numerous unforeseen negative consequences...

Nikola Tesla once dreamed of being able to harness electricity from the air. 
Now, research being conducted at Brazil’s University of Campinas (UC) is 
indicating that such a scenario may indeed become a reality. Professor Fernando 
Galembeck, a UC chemist, is leading the study into the ways in which 
electricity builds up and spreads in the atmosphere, and how it could be 
collected. “Our research could pave the way for turning electricity from the 
atmosphere into an alternative energy source for the future," he stated. "Just 
as solar energy could free some households from paying electric bills, this 
promising new energy source could have a similar effect.” 

Scientists once believed that water droplets in the atmosphere were 
electrically neutral, even after having come into contact with charged dust 
particles. Galembeck and his UC team, however, have shown that this isn’t the 
case. In a lab experiment, they noted that tiny particles of silica and 
aluminum phosphate became negatively and positively charged (respectively) when 
circulated in highly-humid air. “This was clear evidence that water in the 
atmosphere can accumulate electrical charges and transfer them to other 
materials it comes into contact with,” Galembeck explained. “We are calling 
this 'hygroelectricity,' meaning 'humidity electricity'.” 

He now pictures collectors, not unlike solar cells, that could someday collect 
and distribute hygroelectricity from the air. Just as solar cells work best in 
sunny places, his collectors would do best in humid parts of the world. He even 
believes it’s possible that by diminishing the electrical charge in the air, 
his collectors could prevent lightning, especially if mounted on top of tall 
buildings. His team is currently experimenting with different metals, to find 
out which would work best for capturing atmospheric electricity and preventing 
lightning strikes. 

"These are fascinating ideas that new studies by ourselves and by other 
scientific teams suggest are now possible," he said. "We certainly have a long 
way to go. But the benefits in the long range of harnessing hygroelectricity 
could be substantial." 

A report on Galembeck’s research was presented this week at the 240th National 
Meeting of the American Chemical Society .
