A new energy source is being utilized in Europe: people! In France, they put down a special flooring on a particularly busy street that can harvest energy from feet hitting the floor. They got the idea from a night club that had a similar flooring. French officials are hoping that the foot traffic of the day will power the street lights at night.
In Sweden, scientists have found a way to harvest body heat. A busy train station has been set up with a system to harvest the body heat which is used to heat tanks of water and eventually heats neighboring buildings saving on electricity costs. Many people are critical of both of these systems because of the high development costs, but as long as it is conserving energy, I am all for it. There will soon come a time when saving money will not be everyone's first thought with regards to energy.
