Daniel Halladay
http://farm4.static.flickr.com/3366/3412987586_6de4b396cf.jpg
-Born in Vermont in 1826
-Invented the self-governing windmill in Connecticut in 1854
-Manufactured windmills in Ellington, Connecticut from 1854 to 1863

Solid Wheel Windmill - 1867
-Invented by Reverend Leonard H. Wheeler in 1867
-More rigid design composed of a fastened wheel attached to a hinged vane
-Major competitor of Daniel Halladay

Metal Windmill 1870’s
-Had curved blades which were much more efficient
-Had “back geared” system which made it turn easier in lighter winds
-People didn’t like them at first because they seemed fragile and difficult to repair
-By 1940 all windmills were made from iron and steel

Super High Tech Windmill 2011
-Made with strong anti-rust metal
-Bike wheel and tape design for extra durability
-Creates beer*
*does not actually create beer

How it works
Basic Components- Rotor/Fan
- Converts wind energy into rotary motion - Gear Box
- Converts rotary motion of fan into reciprocating motion
- “Sucker Rod”- Reciprocates to power underground pump
- Pump- With each motion of the sucker rod, draws
water upwards through a one way check valve

Fan and Tail

- 15- 40 curved, steel blades- Fan guides apparatus which pivots
so that it always faces the wind

Typical Gear Box

- Key component in converting rotation of the fan into up and down motion of the “sucker rod” to power underground pump

Hydraulic Pump
http://www.windmills.biz/windmill%20pump.gif
http://www.aermotorwindmill.com/Links/Education/Index.asp
- Water drawn into pipe with upward motion of of sealed plunger
- One-way valves prevent water from exiting through intake
- As plunger travels down, water is forced up toward surface

Building a Windmill
Easier said than done

Materials
• Bike Wheel
• 2 chain rings
• Bike chain
• 2 Check valves with PVC
• Some sort of structure
• Scrap metal

Tools
• Welder
• Grinder
• Screw driver
• Crescent wrench
• White lithium grease
• Hammer
• Garden Hose
• Hack Saw

How It Works
• Wind spins the bike wheel which moves the chain
• Turning the bottom chain ring and the shaft
• Pump goes up
• Check valves create suction that brings the water into the PVC
• Pump goes down, pushing water out the second check valve

Current Manufacturing
• Usage of water pumping windmills has declined since the early 20th century
• By the 1970’s only three companies still produce water pumping windmills

Disadvantages
• Outdated
– Use of electric pumps delivering 20-30 gallons a minute hurt the windmill era
• Dependent on wind
• Small margin for error

Conclusions
• Windmill needs a strong wind to work
• Pumps little water at a time
• Air/water tight seals very important
• Friction is the enemy
