We started out learning the basics. Designing, building and testing flat blades in the one foot long range with 8:1 gear ratios. Three of the teams performed at a level high enough to be invited to compete in the National KW Challenge. The national level of competition would require a higher level of performance and we are rising to the challenge. Their first turbines were producing 20 Joules of energy and now they are producing 60 J !
In the spirit of learning and promoting KW and RE education here are some of the changes I have made to the original KW equipment that have helped the teams.
It will also be necessary to reduce the thickness of the 1/4 nuts to 1/8" thickness.
So there you have it. I believe in sharing this to promote learning and the KW program. There is more than just watts in the power we are producing. I have all the pictures and details that go along with these changes to the equipment. Email me if you need or want more information or I can be of any help. Hope to see you at the National KW Challenge.
