Space Manufacturing Could Need Acoustic Levitation 

When a ballistic shield is struck with a heavy object, it can actually bend backward toward the shield holder. Researchers want to know if these shields do enough to protect against arm injury.

How Well Do Shields Protect? 

Yes, says Bechel&rsquo;s John Gülen, but probably not in some of the carbon-neutral applications that have received attention over the past decade.
