POWER THE WORLD
With Your Movement
Tumble is a revolutionary wearable wristband that converts your excess arm movement into stored kinetic energy. Every step, every gesture, every run—automatically donated to power remote sensors, environmental monitors, and IoT devices in off-grid areas around the world.
THE WOW MOMENT
You look at your wristwatch after a morning run and see a map pinning a weather station in rural Montana that just came online because of your movement—along with a thank you message from the farmer who now has access to real-time frost warnings. A sensor in the Amazon rainforest starts transmitting data because you danced at a concert. A glacier monitor in Iceland wakes up because you waved goodbye to a friend. Your everyday movements become extraordinary moments of impact.
