First I thought I should wait until I gathered enough data from my tree data collection, but I can't wait to build something, so I ordered some parts in advance :)

• First I want to build a low RPM axial flux generator, so I ordered some magnets and copper wire on Ebay. It will be not the version I will use in the field (since I don't know the optimal RPM range yet, this depends on the most common swing frequency of the trees), but I think I can learn how to design and build such a generator :) Fortunately I have the rest of the materials needed (bearings, silicon for the mold, resin for stator and rotor already in my workshop).
• Second I want to build a energy collection system based on liquids (see also my Brainstorming project log), therefore I ordered some tubes and pipes. I plan to compare these both methods based on tne price per watt of output power.
