Optimal Human Habitat Design thru Fractal Modeling

Soleri mentions metabolic structures of cities need to model the human body! at Ecocities Conference

Fractal Mandelbrot NOVA show shows fractal nature of body's organs! some mention of energy use of mouse compared to elephant


KK mentions this in his article on the NooSphere Machine the Android Meme! Bob!
On average the cells of biological organisms have a resting metabolism rate of between 1- 10 watts per kilogram. Based on research by Jonathan Koomey a UC Berkeley, the most efficient common data servers in 2005 (by IBM and Sun) have a metabolism rate of 11 watts per kilogram. Currently the other parts of the Machine (the electric grid itself, the telephone system) may not be as efficient, but I haven't found any data on it yet. Energy efficiency is a huge issue for engineers. As the size of the One Machine scales up the metabolism rate for the whole will probably drop (although the total amount of energy consumed rises).

Elephantine metabolism

"The largest organism we studied is the elephant, which has a metabolic rate of 1 Watt per kilogram, and the smallest is a bacterium with a metabolic rate of 4 Watts/kg," says Makarieva.

Using the formulae that had previously been used to calculate the metabolic rate within separate classes of animals, you would have expected a multimillion-fold difference, she says.

Since such a large number of species falls within this narrow range, she hypothesises there may be an optimum metabolic rate for all organisms. "Organisms that lie close to this value may be the fittest to survive," she says.
