Teaser
Hydrogen (Wasserstoff) was discovered in 1766 by Henry Cavendish, an English scientist, when he made base metals react with acids (Säuren). He called the element "phlogiston". In 1783, A. L. de Lavoisier succeeded in synthesizing the gases hydrogen and oxygen to water. Lavoisier then named hydrogen after two Greek (griechisch) terms: hydro (water) and gennao (I generate) as "hydrogene" – “I generate water”. In 1814, the element symbol "H" was introduced by Berzelius, a Swedish chemist. But how has this element changed over the years?

Oil heating
Switzerland with its 45.7% has the biggest proportion of oil heating in Europe. Which means that almost half of the households in Switzerland still use a non-renewable energy source.
Advantages
- The house doesn't need to be connected to the gas network.
- You can choose your supplier yourself.
- As long as you have oil in your tank, the house is always warm.
Disadvantages
- High and repetitive costs.
- Space needs to be saved in the cellar for the tanks.
- High CO2 emissions and damage to our earth with obtaining the oil from our earth.
Also, the canton of Zurich just voted on a law concerning our heating sources, especially oil heating. It got accepted, which means that if an oil heating source is non repairably damaged, it has to get replaced by an environmental friendlier heating source if it.

A radio with 15 watt, it plays music for four hours, consumes 0.06 kWh.
The math behind it: 15 W x 4 h = 60 Wh (0,06 kWh).
What can you do with 1 kWh?
- About 133 slices of toast in a toaster oven
- Leave an energy-saving lamp burning for about 90 hours
- About 50 hours of working actively on a laptop
- Watch about 7 hours of TV
- Iron about 15 shirts
- Run a refrigerator with a capacity of 300 liters for about two days
- Do about one wash cycle with the washing machine
What is soil?
Soil is so very important because we need it to survive. Without it we wouldn't have any food nor nature,
which can provide us with oxygen.
What are its functions?
The soil regulates the natural cycles of water, air and orgaic and mineral matter. It filters and purifies water, stores and breaks down substances and is therefore a vital link in the constant flow of energy and matter throughout the Earth's entire ecosystem.

My house is heated with oil, which means my heat source would as well be oil. It is a really old house, that's why we don't have any other type of heat source.
How does it work?
A heating system that uses oil for fuel relies on several different components to properly heat a home. The components that are often part of an oil-fueled heating system are:
- Oil tank: The oil tank stores the oil until it needs to be used by the heating system. Oil tanks are available in a variety of sizes and shapes, including horizontal and vertical tanks. They might be located above or underground.
- Filter: The filter removes sediment and debris from the oil as it flows from the tank to the heating system.
- Fuel pump: The fuel pump controls the movement of the oil from the tank to the heating system.
- Combustion chamber: The combustion chamber is where the oil is ignited, so that it can warm either water or air, depending on the type of system in place.
- Thermostat: The thermostat measures the temperature in a particular area of a house. When the temperature falls below the set level, the thermostat triggers the heating system to kick on.
When an oil heating system gets the signal that it needs to warm up a house, the oil gets pumped from the tank into the combustion chamber. Usually, the oil is under a lot of pressure as it enters the chamber. Once in the combustion chamber, the oil is lit on fire. Although older oil heat systems featured a pilot light that was burned continually, newer models feature electronic ignition. A flame is only lit when the heating system is running through a cycle.
