describes itself as follows:
 Sustainable Waves specializes in sustainable solutions for the entertainment industry. We provide solar powered stages & sound systems and a variety of conscious products and services. From pollution free concerts to innovative products, Sustainable Waves is a logical approach to creating value. With artistic inspiration, we integrate with existing business models. Taking one step at a time, we strive to inspire the currents of the global economy.
This is, of course, a lovely idea. But the precise terms of the idea – well, they’re not so precise. The second sentence describes “solar powered stages and sound systems;” the third sentence uses the words “pollution free concerts.” My reading is that this implies that all of the electricity used on stage and to reinforce the sound during the concert, beause of the phrase “pollution free.” “Pollution free
” (emphasis mine) concerts would have no pollution generated by any aspect of the concert – including transportation of performers, crew, house staff, and audience.
It’s possible, too, that they’re only using it with small audiences, during the day and out-of-doors – reducing the energy needed for lighting and sound reinforcement.
Possibilities of exaggeration or imprecision aside, it’s a great idea, especially if audiences see the PB panels on their way in and out – not to mention people who see their PV trailers on the road. (photographs here)
