tip turbines are big on power and marvels to calculate at . They ’re also rather inefficient . So some scientist remember about it , blab , and envision out a way to increase their powerfulness output tenfold . All by star at fish !
John Dabiri , prof of astronautics and bioengineering at Caltech , and his colleagues set out to prove the conjecture last summer at his Field Laboratory for Optimized Wind Energy . They ’d observe that current Horizontal Axis Wind Turbines , or HAWTS , require a draw of space since hinderance from adjacent turbine ’s wakes , or wind disturbance , causes them to perform less optimally . More space means more money .
But Dabirinoticed somethingabout schools of fish that he could flex to his work :
“ I became animate by observations of schooling Pisces the Fishes , and the suggestion that there is constructive hydrodynamic interference between the wake of neighboring fish , ” says Dabiri … “ It bend out that many of the same physical principles can be applied to the fundamental interaction of vertical - axis wind turbines . ”
In other word , the fish used the cruise paths of their neighbors to their advantage . The same could be applied to wind turbines . Vertical Axis Wind Turbines to be exact , which count more like merry - go - rounds than they do fan . Pack these guys together and the clockwise rotation of one turbine will serve power the counter - clockwise gyration of another . And so on and so onward until you really see the results :
The six VAWTs yield from 21 to 47 watts of powerfulness per square meter of land area ; a comparably sized HAWT farm bring forth just 2 to 3 Isaac Watts per square measure .
That ’s unbelievable . The next coherent step would be to push for these idea to be implemented as cheaply as possible in areas that could use them . And , at the very least , I now have a newfound appreciation for tuna . [ CaltechviaGreen Car Congress ]
