Logarithmic scaling in an African Windscreen

He said that the long rows use less straw and less time. But here in the Sahel, we have strong winds and dust. The shortest rows are the ones that keep out dust the best, because they are the tightest weave. But they also take more materials and effort. "We know that the wind blows stronger as you go up from the ground, so we make the windscreen to match -- that way we only use the straw needed at each level." Its an indigenous cost-benefit analysis! And the scaling exponent is close to that in the Wind Engineering Handbook. Next Page >>
