Maybe this tech or this company will peter out before reaching mass-market scale. But advances in solar technology are coming faster and faster. (Small, distributed energy technologies are inherently more prone to innovation than large, capital-intensive energy technologies.) Sooner or later, solar will be woven seamlessly into the fabric of our lives. Our built environment will harvest energy as a matter of course (from the sun, from the wind, from waste), store it effectively, and use it wisely. Power harvesting and power management will be ubiquitous; power imported from large, distant, polluting power plants over long-distance transmission lines will come to be seen as back-up, a necessary evil. And perhaps, someday, an unnecessary one.
