The device relies on the hopping motion to propel the ski forward.It is made from aircraft grade aluminum and has a wingspan of seven feet. For the propulsion the device relies on a fiberglass spring.
The hydrofoils create minimum drag which allows it to go up to 17 miles per hour.
Moreover it is much easier to carry than any other conventional ski as it can easily be folded and packed into a duffle bag.
The device is pollution free and is powered by humans, but still the $500 price tag makes it difficult to own.
