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

One Big Circle’s AIVA (Automated Intelligence Video Review) creates vehicles that can see, transmitting live video via a small hardware box to allow problems to be addressed immediately and effectively. 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.
