People often don't think of biology as technology. But the thing is.. that's because the technology of life is SO far ahead of our own engineering that we don't recognize it as advanced machinery!

Via Niko McCarty on the bird site:
ATP synthase spins about 230 times per second at room temperature.

At 45ยฐC, it can rotate 650 times per second (๐Ÿ”ฅ).

A typical jet engine spins 150 times per second.

Biological engineering > mechanical engineering.

@bert_hubert very interesting

@bert_hubert update the aphorism to "any sufficiently advanced technology is indistinguishable from metabolism "?

@nuthaven hmmno metabolism is a bit too specific for that.

@2342 .. per second v per minute.

@bert_hubert you're right, but this spinning is not an indicator..

The surface area the force has to go through scales as sizeยฒ the ourward force F=mฯ‰ยฒr (ฯ‰=2ฯ€frequency) that `r` is the size scale, so it the force actually there scales linearly..

Lets say the one is 1m across and the other is 1um, then the smaller one has a 10^6 advantage in forces, and given that square, 10^3 in rotation rates, a fair comparison 650/s is 0.65/s for the turbine..

@bert_hubert biology in the cell is 3d computing. It's very different from software therefore.

@bert_hubert It deserves a tag: #nanotechnology
