Great engineers (according to the BBC)

I smiled when TED gave a slot to a boy who they hailed as an engineering hope for Africa when he had managed to follow plans for a small farm windmill and assembled it from standard parts… That’s not actually innovation, I am afraid.

 

But today on Radio 4’s women’s hour we heard of young british woman who had made an evaporative cooler (yip – putting a wet blanket over a box, with a lid). This was hailed as a design breakthrough. I couldn’t see it, and I couldn’t see, either, how useful this would be given that her first (yes, she’s a multi award winner) prize wining design was for a wheel-barrow to carry — you guessed it — water!

An initial wonder concerns whether African’s can really have failed to develop the wheel barrow, or if, perhaps more likely, the tracks they are carrying water over make the alternative of carrying one bucket n your head better than pushing 5 on a barrow).

But aside from that, what use is a terribly inefficient, and ineffective passive evaporative cooler going to be in an environment where water has to be carried several miles, 5-gallons at a time?

Given that neither the ‘wheel barrow’ nor the ‘water power refrigerator’ are even engineering or design breakthoughs, let alone inventions, this seems to set a low bar for aspiring female engineers. But maybe that’s the point.
