Amherst took one giant leap into the space age of trash removal by installing solar powered trash collectors in the downtown. The $4,000 units, purchased with a state energy grant, hold about 5 times the amount of normal trash. A built in sensor detects when full and then engages the compacting phase. And it's powered by solar cells located on the top of the unit. Thus saving labor and space at the landfill.
Downside is you can't practice basketball with crumpled paper like you can with the basic $100 receptacles because you have to grab the handle and open the unit, which some germphobes may find a bit disconcerting.
