Nils and I wanted to find out how long you need to run at a constant speed to produce enough energy to bake a cake.
We've found out that a human being is able to produce 80 Watt hours, if he trains one hour on the dreadmill.
To bake a cake for 20 minutes the oven needs 950 Watt. So we calculated the number of hours you need to run.
Naomi and I wanted to find out how long you need to train on a crosstrainer to produce enough energy to bake a Pizza.
We've found out that a human beeing is able to produce 80 Watt hours, if he trains one hour on the crosstrainer.
To bake a Pizza for 15 minutes the oven needs 900 Watt. So we calculated the number of hours needed to
produce 900 Watt on a crosstrainer. The result is XXX.
If you would buy the energy you would have to spend only 30 cents.

Sustainable Soil Management: Soil for Life. This course is for anyone who is interested in learning why soil is so important, how it is being threatened and what we can do to protect this natural resource so vital to our lives.
In an average week Justin consumes about 3 Döner. How many hours could Justin have operated an LED lamp with the energy he consumed ?
100g of Döner contain 770 kJ
1 Döner is about 330g
the energy consumption of an average LED lamp is about 60 Wh per hour.
(1 Wh = 3600 Ws (Wattsekunde) = 3600 Joule = 3,6 Kilojoule (kJ).
Debora and I wanted to find out how long you need to ride a bike to produce enough energy to dry your hair with a hair dryer.
We found out that a women (1.70m/63kg) is able to produce 120 Watt per hour, if she rides the bike for one hour.
Every time after showering we both blow dry our hair, but how much watt does a hair dryer need?
We found out that a hair dryer needs 2000 Watt to dry a womans midle long hair in 8 minutes.
So we calculated the number of hours needed to produce 2000 watt while riding the bike.
What is the result?
[please upload the image again in the correct way]
1 Juan = 1HP = 746 Watts = 0.75 KwH
1 Rodolfo Sanchez= 1.60 Meters
It takes 2.5 Juans to traverse 1 Rodolfo Sanchez.
For better comprehension, here is a picture of 1 Juan and 1 Rodolfo Sanchez for scale.
Here is an article I found. It is about how humans are on the best way to destroy the place where we live.

My questions for my collaborate meeting call on Thursday:
Task: "The Bee's and their life in climate change"
- Do you know the importance of the Bee's?
- Are there also beekeepers in Spain? Ist that a usual hobby? Do you know somebody?
- What do you think about the bee's and the climate change?
- Are you interested in my task or in a collaboration together as well? Is there a possibility to observe bee's for you? Or what kind of collaboration is possible?
In one weak second, you devour a whole 6-pack of Snickers. About how many hours could you have operated an LED lamp with the energy you consumed at that moment?
100g of snickers contain 2014 kJ
1 bar of snickers is about 50g
the energy consumption of an average LED lamp is about 60 Wh per hour.
(1 Wh = 3600 Ws (Wattsekunde) = 3600 Joule = 3,6 Kilojoule (kJ).
If you drink one whole bottle of Absolut Vodka (0.7l), how long do you think it takes the body to decompose the alcohol when doing sports (running) and does it speed up the process?
For reference:
Normal bottle size = 0.7l
Man degrades 0.15 promille/h
Woman degrades 0.13 promille/h
Here you can calculate how long it would take you to decompose the alcohol
--> This result is without doing sports
Important!
Do not forget to adjust the number of liters to 0.7l
