I have a secret ongoing project. It called human-power high altitude drilling machine! Major parts are two components. One is human body development program and another is hand drill system. This is based from shaft drive bicycle unit!  I could not fined such bike in town, then we order this and taking a part.

Then we attached drill system.

It drill. But…It will brake connection part in the mountain. We still need work to improve this system!

Proto type was failed but this is good start. New things are always need time and energy to develop! Stay tune I will report “proto type II”.
