that paper spinning thing, was invented in the Dominican Republic in 1965, and its called FuFu because of the sound its make when it spins, it was also a toy, and people instead of using paper they flattened soda caps with a hammer to make it, the intention of the game was to cut the other players rope.

Not sure about the paper version specifically, but there are records of similar toys having been made out of different materials in the early 1800s. And according to the Wikipedia page, native American cultures and China had something similar as far back as 400-500 B.C (I didn't fact-check the sources, though).

With a solar panel and lithium cells you can have low demand electricity anywhere. Also there is an aspect of efficacy to the expensive equipment, you can load 20 samples and go accomplish stuff, and the samples can be larger and better precessed for less uncertainty in the results, the types of tubes used have other testing advantages as well and the machines last for decades of near continuous use(like 10 million samples); The paper spinner does one or two tiny samples and requires somebody to spin it for 10 minutes, at a cost of $30 an hour that's about $3-6 per sample; not including the amortized machine cost, this would be 30-60 million dollars for the same number of samples that the big machine processed for only a few thousand dollars including cost of electricity. Please know that cost for an employee is not the employee's pay, usually the cost is near double the pay rate.

Why not the cheaper hand operated ones? Theyre just around $50 new. The problem I see with this one is it has to stop for just a bit when its switching the rotation direction. Not sure how import that is, though. Also, if something breaks, the operator is going to get a face full of glass and blood >_

I think the bottleneck will be the force required to pull the strings, and the durability of the device. If it's made with paper + fabric thread, I'm not confident it would withstand hundreds of cycles of pulling and spinning with heavy samples. So you'd probably need something more durable and somewhat more heavy and expensive. I imagine it would still remain far more economical than a conventional centrifuge, though.
