Sometimes a new path becomes clear when you see the pitfalls of the old one. Brian Gramm was researching large-scale renewable energy, such as wind farms, when a totally new approach dawned on him. Rather than trying to make green energy look like the old, big-plant electrical grid, why not generate power right where it’s used, and let consumers have their own miniature power plants that can go anywhere?
“There are situations where large-scale solar is right, like office buildings. But the things that most of us use daily, most often, really don’t require much power,” said Gramm. He co-founded Peppermint Energy, a South Dakota company that makes a portable, plug-and-play solar generator called the FORTY2. Like a solar plant in a suitcase, the FORTY2 draws enough juice from the sun to power lights, laptops — even a dorm fridge. A battery stashes power and delivers it after sundown.
The solar generator can power several devices at once, and even delivers enough juice for a small refrigerator. Its battery provides power after sunset.
“It’s only when you see it in physical form that you realize the form and function should be the same.”
