AI Thread Summary
The discussion revolves around the idea of repurposing a wind generator design to create a water pump by reversing its operation. The proposed design involves using a wheel with magnets inside a tube, while the coils would be positioned outside. Concerns are raised about the efficiency of this setup, with suggestions that it may function more like an inefficient fan rather than an effective pump. The creator expresses hesitation about starting the project due to time and cost considerations, while also noting potential applications beyond just pumping water. Overall, the feasibility and efficiency of the design remain in question, with a humorous suggestion to place it under an air conditioner for added energy.

hi, I've been inspired by this wind generator design: http://www.instructables.com/id/Pringles-Wind-Turbine-Pleech---Version-One/
to make it operate in reverse, that is, feed alternating current and make the thing spin.
The purpose of this is to make a pump by putting a wheel (similar to those seen in airplane turbines) inside a tube, and fixing the coils outside of the tube. The weel would have magnets attached at the rim (like the one in the generator). Do you think that it would work? would i need to synchronize the current so the wheel won't jam? what advices can you give me?

You would basically just be making a very inefficient fan. You could do it, but I don't know why you would.
 
It's a very inefficient generator that steals energy from your air conditioner fan.
 
hi, i still got to get my hands dirty and i can't find the time or motivation to get going (and i don't want to spend the money in buying materials unless I'm 100% sure I'm going to go through the whole way). The end product i have in mind would be a tube section with a fan at the middle, and the wires outside, so with the proper fan i could have a way to pump water through the tube. My first idea was to use it in a hydroponic system, but if the fan is made properly i see no reason why it would be limited to water.. I've heard that most water pumps should not be operated without water, but this one should work either way.

you can always put it beneath somebody else's air conditioner :D
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
