Salmon have a problem : Man - made obstacles are making it knockout for them to complete their epic journey upstream to spawn . While some dike are equipped with what are called “ fish ladders ” that help the Pisces crossbeam , other dam , like the 236 - human foot - tall Chief Joseph dam , or the 550 - human foot - magniloquent Grand Coulee dam , are far too big to be scaled . And if salmon ca n’t get back to their mating grounds , they ’re not the only ace with job . These creatures are fantastically important to the natural existence . After they breed , they often die in the river , and their physical structure soak the water and its surround with important food . As theWild Salmon Center , a conservation organization , puts it , “ It is no coincidence that the largest remaining universe of apex predators such as brown bear and eagles hap where they are still respectable salmon run . ”
But fear not , salmon lover , a company calledWhooshh Innovationshas a plausible root : the salmon carom . Using pneumatic tube primitively designed for quickly transporting green groceries , Whooshh has found a way to safely transport and propel Salmon River 100 human foot into the air . " We put a tilapia in the fruit tube , " Todd Deligan , Whooshh ’s frailty president , told The Verge . “It die fly , and we were like , ‘ Huh , agree that out . ' "
Once the salmon are in the tube , a vacuum is create , and pressurized air behind the fish pushes it forwards until it shoots out the other last at speeds of up to 22 mph .

If you ’re worried about the Pisces , they ’re kept moist in the underground , and show no evidence of harm . The system can transport up to 40 Pisces per bit . The salmon cannon , while true a bit ridiculous at first glance , could be brassy than building new Pisces run and easier than collect salmon and transporting them upriver in hand truck or barges . Whooshh started testing the tubes on salmon at the Roza Dam in Washington body politic in June .
