Hydrogen energy cycle

Hydrogen economy as a model. Photovoltaic delivers electric power, electrolysis splits water, hydrogen stored, fuel cell delivers electricity.

Energy saving fair Wels 2005

Fair report from the Wels energy saving fiar in March 2005. Self experiences as an engine for a heat pump and with an infrared camera.

Self photo with infrared camera
What is normally used to make cold bridges at houses visible is here used as a fair attraction. An infrared camera shows pictures on 4 big screens.

Home exercise kit heat pump
The theory is well known. Higher temperature difference between cold and warm side causes more energy demand for the heat pump.

Heat pump demo
This modified home exercise kit is for the illustration of the heat pump. The compressor powered by human muscles takes the coolant.

Hall heating with wood pellets
Minus 9 degree Celsius 10:00am on the parking lot of the fair. To warm such a tent like fair hall, it's better to rent a 800 kW pellets heating.

Sheep wool insulation
Each cubicmeter contains 16 kg sheep wool. Each sheep delivers about 2 kg wool per year. But how does it happen, that wool is nearly not more expensive than other insulation?
