An article in the Wired, brings into focus a paper and string arrangement which does not look like anything of value. However, the article calls this innovation by Manu Prakash , a bio-engineer from Stanford University, a minor miracle. Prakash’s innovation is an inexpensive centrifuge, aptly called “Paperfuge”. Paperfuge is made of paper, string and plastic and does not use electricity. It achieves 125000 rpm, enough to separate plasma from blood an important step in many critical diagnosis tests. It does all this weighing 2 grams and costing less than 20 rupees.
A serial innovator, Prakash made believes in frugal science. He developed a folding paper microscope using origami in 2012.
