The idea for the Grengine came to her five years ago, when she was walking her (finally napping) three-month-old twin boys and came across a construction site running a very loud diesel generator.
“Everything with twins is about sleep,” Stacey says. “I thought: if you wake these boys up, I’m going postal.”
The twins didn’t wake, but Stacey couldn’t shake the thought that there had to be a quieter, more environmentally friendly way to power that construction site.
Drawing on her experience in the IT industry, she began to design a lightweight, portable, battery-powered generator. “The idea unquestionably came from the basis of a UPS (uninterrupted power supply) in a server room,” Stacey explains.
She floated the concept by some tradespeople — roofers and framers that she knew. They all had the same feedback: that would be great, but it’s easier to fill up a gas can than to recharge a battery.
That’s when Stacey came up with the idea of the world’s first portable, plug-and-play, scalable power system. “I thought on it and came back. I said: ‘What if you just swapped the batteries or stacked them up?’ And they said: ‘Done!’”
Grengine’s lithium-ion battery packs fit together like blocks of Lego. This patented design allows users to swap or stack additional power units — safely and instantly creating more powerful energy systems, without the need for a technician.
The generator is input agnostic and can be recharged using an electrical socket, solar panel or kinetic energy. (In fact, Growing Greener is currently developing its smallest kit, the Grengine Micro, to include a foldable hand crank at the request of the American and Canadian militaries.)
