The Boston-based company Frigid Dynamics is the developer of the E-XC--a set of motorized skis. These electric-powered machines have treads in the back that push the skier along the powder at high speed.
A set of these machines can propel a user up to 20 miles per hour for 10 miles. They can climb grades as steep as 20°. Users control them with a wireless device in one hand and a ski pole in the other.
Imagine this invention in the hands (or, rather, on the feet) of mountain rescue personnel or ski troops.
