Average Finnish “Inventor” in the process of innovating new way to get to work. Can someone briefly explain this genius idea?

  1. So the base is classic kicksled

    Under the front “seat” there is large’ish metal container, filled with water, and the nozzle is pointed at the rear. of the kicksled.

    The water container is filled with water, heated over open flame to around 400 Celsius, And as the heat rises, the water expands, and turns to steam, Except it doesn’t have room to expand, and therefore just heats up and gathers pressure.

    When there is enough heat, and the valve (still pointing at the back of the sled) is opened, the water starts instantly expanding and turnig in to steam, and as it has only one way to go,, which is trough a small nozzle, it turns in to steam jet.

    While water turns to steam quite rapidly, it has huge acceleration on start, some acceleration early on, it works essentially as a steam jet. Propelling the sled for short distance, but at very high speed.

  2. this is what the voice over is telling:

    It accelerates 0-100km/h in less than 4 seconds. A group of guys in Östersund (Sweden) have developed this “rocket kicksled” which is propelled with steam. 15 liters of water is heated up to 400 °C in a pressure tank which gets over 50 bar. The traction force at the start is above 100 kg. Currently the world record on this steam kicksled is at 105.2 km/h but it is expected to go faster. The new attempts to world record will be made during spring.

    combine this with the previous comment

  4. Yes its simple. Finnish people have to go to work, school etc in winter. And polar bears can be slow to ride sometimes so have to innovate new things
