I am working on some ideas to do some artcycling projects along the bike path making public art installations that are wind powered air compressors kinetic sculptures the air is free to use to air up tires on your bike. Also build in a small 3d printed electric motor connected to a 3d printed turbine and it can charge a cell phone or iPad. The wind captured in the tank can also flow through a wind instrument to make it a public instrument you play with captured wind as it charges up the cell phone and airs the tires for free. After having low tires out on the path this is a welcome thing.
I am in the idea phase of the project and the parts are becoming clear I thank you for inspiring me to see a way to create public works of art to benefit others. I have much work to do to pull off something like this the result will be pen source plans on how to replicate them to add to the steem parks.
