What is a thermostat?
A thermostat is a controller that reacts to a set temperature (temperature controller). Depending on the setting and measured temperature, it influences the flow of a fluid - for example, for cooling an engine, in a refrigerator, a fixture in the kitchen or bathroom, or on a radiator.
How does a radiator thermostat work?
The temperature controller of a heater reacts to the existing room temperature. The set temperature is adjusted at the thermostat head.
If it is warmer in the room than the temperature set at the thermostatic head, a pin at the bottom of the valve is pressed in and the opening of the valve is restricted or closed. Thus, less or no heating water flows into the radiator.
If it is colder in the room than the temperature set on the thermostatic head, the valve is opened. This allows more heating water to flow through the radiator until the set temperature is reached. Then the valve automatically closes a little to maintain the set temperature in the room.
million tons of food are ending in the carbage and million people also dying every year because of malnutrition:
issue:
for producing food it contains a lot the enveirenment, so it's really bad when people, restaurants or supermarkets have to throw their food away.
My idea:
- set up a store/restaurant, where people can bring their food they won't eat or use it anymore:
- Restaurants or supermarket could also join this store
- possible to buy quality food for low price in this store (lower budget familiy)
- cookers works in this store, so its also possible to eat lunch/dinner there
