Transcript of PanzaPath: Water wheel evolution
Conventional wisdom = ??
= OK
A long time ago, water wheels were used on rivers for a lot of things,
Then electricity discovered
electric motor invented by Faraday
Then the steam engine was invented
which together brought the
industrial revolution
It’s called a turbine
water wheel connected to electric motor
Impulse turbine
Kaplan
Tubular Francis /S
Bulb
Diagonal
Reaction turbine
Thoma
Cross Flow
Turgo
Pit
Axial Flow
Fancis / Mixed
Water Wheel
Pelton
Propeller
Many different kinds of turbines
Bigger and BIGGER..
Then they built dams
inside the dam wall
and put the water wheel
using the force of the water flow,
But: dams cause problems
so, they put the turbines
next to the river
and use coal for steam from the river water
But: coal causes problems…
Now we have a situation…...
So they
cut trees
rivers
Next to…
And burnthem
Some collect
firewood….
causing
problems
homeless,hungry
So; from environmentally friendly
to this……….
Killing two million a year
There are solutions ……
Old technologies - not scalable
Newer Designs not always suitable
A Power Pontoon floats
No construction needed
The latest award winning idea
Improved water wheel
Small,
or BIG
Darkest Africa
most rivers
Powerful rivers
By doing this
We can use this
To prevent this
