On a recent blustery afternoon, scientists gathered on a rooftop at the Georgia Tech Research Institute (GTRI) to observe two atmospheric electric field-mill devices monitor the buildup of electrical charge in nearby clouds. The larger device was a commercial model costing about $5,000. The smaller one, built by five Georgia high-school students using a coffee can, electrical components and a motorcycle battery, cost about $200.
