65 Unexpected Energy Sources

You won’t find anything powered by wind, water or the sun in this roundup of unexpected energy sources. These unusually powered creations harvest energy from alternative sources like workouts, tweets, falling sand and chocolate.

Sustainability is ever-present in the minds of designers, engineers and architects and it is becoming increasingly important to come up with clean and creative energy sources. Buildings, cars and products that demand high amounts of energy are making use of solutions like kinetic energy and biofuel for increased efficiency.

These alternate energy sources make the most of out-of-the-box thinking. Some of these ideas pair similar concepts together, such as trash-powered garbage trucks and stair-powered buildings. Other ideas mash up unusual objects like billboards that run on the power of fruit, cars fuelled by alligator fat and poop-powered motorcycles.
