The ARA Wetzikon has reached its limit. 37'000 citizens are registred in this system and according to 2018 the ARA Wetzikon is working 120%. So the system is overloaded. The municipal is trying to figure out how to increase the performance. The system is able to keep up the work because of it's hard working employers and financial support of the commune. A petition is already set up to collect money for the upgrade of the ARA Wetzikon.

Heating an icehockey rink
Excel Energy found has written, that there is around 2'000 kWh used to heat an icehockey rink (Kunsteisbahn) day by day. This might be an abstract amount of energy for a normal citizen. What do you think, how many typical cell phones could be charged with the energy which is used to heat an icehockey rink?
Calculation data
As I have already noted, an ice rink needs around 2'000 kWh per day. A typical cell phone needs 0.01 kWh to charge.
Your Solution
Approximately ___ cell phones could be charged with the energy which is used to heat an ice rink.

The term "geothermal energy" refers to the energy that is stored in the form of heat below the earth's surface. At a depth of around 15 metres the temperature of the ground is constant throughout the year. In Switzerland, generally speaking the temperature below the surface increases by around 30° C per thousand metres of depth. The temperature at a depth of 5,000 metres is approximately 160° C. Significant quantities of heat above 40° C are available at depths greater than 1,000 metres. This geothermal energy can be extracted with the aid of a variety of methods.More...
Iain and I have sent an e-mail to KEZO. We asked if we could do an Interview and film several scenes about the recycling procedure of PET-bottles. We are now waiting for an answer.
This is the Elevator Pitch from Claudio & Rico about electric batteries. We are interested how they work, how they are built and how they will be recycled.

I already know how to create a video with a computerprogramm and how to edit it. I created a video as my graduation project in the Sekundarschule. I started recording the scenes with a video camera which i borrowed from a friend. After that I downloaded all video files on my laptop. Then I began to upload it to my editing software called "filmora wondershare". I got a little bit help from my cousin. He has a lot of experience.
I am a hobby-photographer as well. I really like taking pictures of landscapes and sunsets. And I already have a bit experience in sport photography.
The picture is a printscreen from the instagram page of the "Eishockey Club Wetzikon". I took that picture :)
