(The video starts pretty slowly, and doesn't provide much info about how that was built, but it looks fun. There are also plenty of more scaled-up projects, basically looking like combining a ski-doo with a V-1 rocket).
(I actually used a kicksled in the winters to go to school, until I got a moped.)
[update] wow...found one, the kickspark! Awesome. http://www.goslide.ca/en/shop/kickspark.php
In good conditions this can be amazingly fast, and two people can alternate so that one pushes the sled and the other one rests on the seat.

(Hint: What's more Canadian than skating to work? Apologizing for shit. It's what we're known for. Well, that, hockey, curling, Tim's, Don Cherry, and most of the best comedians on US TV and movies over the last 30 years. Sorry 'bout that.)
