Squonk Opera's performances during the Three Rivers Arts Festival are being powered by solar-powered generators that flank the stage in Point State Park.
Zero Fossil Energy Outfitters, based in Munhall, provides the service. The presentation includes a box about the size of a refrigerator with outlets for plugs for the amps and other equipment being used in the show, titled "Pneumatica."
The show -- which features a giant character called Lady Pneumatica and inflatable symbols, percussion and a lung accordion -- "embodies the spirit of Squonk's themes of windpower, and sustainable energy," according to its website.
Steven Kovacik, the founder of Zero Fossil Energy Outfitters, said his company sells and rents a variety of generating machines, from a residential system that can "keep your food cold and your house warm" to a "juice box" unit that's portable. Unlike other generators, these are silent.
Squonk Opera shows today are at noon, 2:30 p.m. and 7 p.m.
