Energym is helping gyms generate green electricity by harnessing the power of exercise.

It uses machine learning to become more accurate over time, and could be particularly useful on railways and eventually in driverless cars.




The Mixergy Tank helps you avoid running out of hot water and reduce your energy bill.
