Using the power of engineering and brilliant inventions to save lives!!! Great times collab-ing with Bill and Melinda Gates! You should check out the Gates Annual Letter here: b-gat.es/2lhhtmJ
Pre-order a paper microscope here- www.foldscope.com/order
Read the published paper on the paper centrifuge, its cool- biorxiv.org/content/early/2016/08/30/072207

Summary: I met with Manu Prakash from Stanford to talk about 2 of his labs' inventions the Foldscope and the Paperfuge. Combined these cost only 68 cents and they can be used to diagnose Malaria. Both of these are examples not only of simple, brilliant design, but of how engineering is used to make a positive dent in the world.

Technically if you re examine the same blood of same human...how many times can you save the same life? You do know that people get malaria several times in the same life, right?

The disc and bars was not invented by anyone actually. They were just made for toys for kids to see how fast they could spin it and then the rope should be pretty hot caused by friction and a portion of energy in converted into thermal energy.
