What's interesting is that SQUID was really inspired by a sea creature, as the Engineering Science Analysis explained. And more importantly, it acts somewhat similar to a real squid as it aims to block the wheels using its sticky tendrils.
“We must make it lighter,” says Mark Kaczmarek, the S&T SQUID program manager. “Also, more affordable, so it becomes the stopper of choice, regardless of budget.”
“SQUID was inspired by a sea creature and a superhero,” added ESA president Martín Martínez.
The manufacturers explain that an used SQUID can be easily recovered and refurbished for later use so the costs are fairly low. However, they admit the whole assembly has to be a bit cheaper in order to allow the authorities to purchase the product and use it on a regular basis. But all these aspects should be improved by 2009, according to the manufacturer.
And beside all of these, scientists say that such a system should be able to stop any type of vehicle, no matter its weight and the speed. At this time, it has proved its efficiency only on a pickup truck at 35 mph, but the goal remains a 5,000-pound vehicle speeding at 120 mph.
