00:00There's a lot of fossil fuels used just for showering in our times.
00:13With our idea we can save like 40% of the energy used for showering.
00:31The heat exchanger is made out of two plates from very thin stainless steel and so there
00:36is a good heat transportation through the material.
00:39The fresh cold water takes the energy from the hot waste water and when we bring back
00:43the preheated cold water to the mixing tap you just need less hot water to get the same
00:49temperature for showering and so you save a lot of energy.
00:55Additionally we've got some plateau where you stand on and that is made from thermally
01:01treated bamboo.
01:02We choose this bamboo because it grows very fast like 30cm each day and it can withstand
01:08all humidity in the shower and it lasts at least 25 years.
01:20We did some calculations that it is possible to shut down at least one power plant in Germany
01:26by just using our device and if all households over Germany use the Warmduscher then we can
01:33shut down at least one of the biggest nuclear power plants in Germany.
01:39That's the goal.
