That's what I think too. I've seen the figures on the aerodynamic roof air deflectors they put on semi-trailers and they can get as much as ~8-10% fuel saving at highway speed (ideal size/fit) where the aerodynamic drag is dominant. Semis average around 6.5 mpg these days (flat, highway) so a 10% saving is close to 1 gph of diesel fuel or about 2.80-3.00$/h. So I'd guess drones would add about 1-1.50$/h in fuel cost or so when they latch on. Enough to be noticeable. |
