In the 1970’s Paul Cunningham, owner and operator of Energy Systems & Design, had a need to power his off-grid house. He set off on a mission to create an efficient and reliable microhydro machine. Utilizing a car alternator type microhydro machine and the wheels he cast himself, he created the first machine. Through many hard-working days and design changes he was able to produce very efficient pelton and turgo wheels and sold these wheels to other enthusiasts.

After years of consistently improving the design he was able to create a highly efficient machine that was producing increased levels of power. It had become obvious that anyone with a suitable water source could be producing their very own renewable energy. With this idea in mind Paul established Energy Systems & Design in 1980.
