==Energy for Designers intro==
  
 +
Energy is one of the big challenges of our society to be solved by you as an inventor designer. We will be trying out weird ways to generate and harvest energy, like algae, chocolate, dance floor, mud, a Joule Thief, body heat and ice. We will also compare this to energy made with a potato, a solar cell, a wind turbine. Or just hack and be an energy parasite! With this experience, you will experiment further and connect your source of energy to your design idea. This can be a product, fashion, or a drawing, illustration, a knitting, architecture or a poster.

Basic calculations, numbers

Consider the energy required to heat 1.0 kg of water from 0 oC to 100 oC when the specific heat of water is 4.19 kJ/kgoC:
 +
Q = (4.19 kJ/kgoC) (1.0 kg) ((100 oC) - (0 oC))

    = 419 (kJ) equivalent to 100 kcalori (food units)

lifting a mass of 100 kg an elevation of 10 m = 9810  J = 10 kJ

Pro 20 climbing stairs =  5 kcal = 20 kJ.

15 Minutes Walking around 50 kcal = 200 kJ
 +
 
 +
Smart phone battery 3300 mAH -> 4Volt * 3.3A * 3600 (seconds)

= 47.5 kJ roughly equal to about 1/8 of a banana

 +
The energy by mass of gasoline is over 12,000Wh/kg. In contrast, a modern Li-ion battery only carries a bout 200Wh/kg; (https://batteryuniversity.com/index.php/learn/article/comparing_the_battery_with_other_power_sources

Energy for Designers intro

Energy is one of the big challenges of our society to be solved by you as an inventor designer. We will be trying out weird ways to generate and harvest energy, like algae, chocolate, dance floor, mud, a Joule Thief, body heat and ice. We will also compare this to energy made with a potato, a solar cell, a wind turbine. Or just hack and be an energy parasite! With this experience, you will experiment further and connect your source of energy to your design idea. This can be a product, fashion, or a drawing, illustration, a knitting, architecture or a poster.

What is energy? 

Cappuccino Energy
47 kcal = 197 kJ (per 100 ml)
12 minutes vacuum cleaning
Smart phone battery: 47.5 kJ = 10 kcal

Big energy for heating houses, cities.

Small energy for your own gadgets and hacks and smart textiles, or charging your smart phones.

Nano energy, from plants, algae, bacteria. 

What is the shape or form of energy as a "design element"?
Is energy "just a power source" in a design or
Can a designer or artist give energy an autonomous place in a design?
