Our Mission: Someday, All Fitness Equipment in the World Will Make Electricity

The Green Microgym and Plugout Technology were invented by Adam Boesel, a school teacher turned personal trainer who started up his first gym in Portland, Oregon in 2008.  While writing a business plan for his gym, he thought, “Wouldn’t it be great if the members could make electricity when they are exercising?” He found although there was a lot of speculation and experimentation about the idea, no one had started up a gym with Eco Fitness as their central focus.

Adam started searching for a way to convert exercise machines into power generators and connect them to the grid.  Several prototypes later, and with the support of a lot of patient and supportive members, he designed the first spin bike retrofit that is grid tied by simply plugging “out” into a normal wall outlet. His design made it easy for anyone to convert their energy into electricity and help power their building.

Adam and The Green Microgym have been featured by CNN, BBC, Entrepreneur Magazine, Fitness Magazine, Club Industry and Club Solutions Magazines, Popular Science, and countless green bloggers.

In 2014, Adam sold his two facilities in Portland, Oregon to focus on helping individuals, schools, and existing gyms around the world to Go Green.

Properly run Green Gyms can use about 85% less electricity and their carbon footprint is about one tenth that of a traditionally run gym, per square foot. A member of The Green Microgym saves about ¼ ton of carbon compared to if they belonged to a traditional gym.

How Schools are Crowdfunding the UpCycle Eco-Charger

“Hi Adam!
That was amazingly fast for a grant that large. DonorsChoose will be contacting you regarding the delivery. We are very excited about having the bikes at Glencoe.  I think that’s obvious by the support for the project!” – Lisa


In the past month, two different schools, one in New Jersey, and one in Portland successfully used innovative thinking to fully fund their purchase of UpCycle Eco-Chargers.  They did it in two ways:

  1. Purchase the Eco-Charger first and then do a fundraising Powerthon
    1. This is the easiest way to do it, by using school or district funds to buy the equipment, and then set up a Powerthon, where individuals and businesses pledge dollars per watt-hour to generate funds.  It can be a one-day or an ongoing thing.
  2. Crowdsource the funding through Donors Choose
    1. This campaign was fully funded in 2 days!  A bit more work up front to write the grant and submit the proposal, but the result was fantastic!

Congratulations to both of these schools and their hardworking, innovative teachers who made this happen!
