The original one actually sounded like something that would be interesting to read, unlike the neutered version ("Lockheed Knee-Stress Relief Device", as of this writing), which sounds like a page out of an ergonomic supply catalog.
I know how sensitive HN is to clickbait, but it does a disservice to interesting articles to hide them behind labels that sound deeply, profoundly uninteresting.
In this case, it has surely come full circle. In an effort to avoid the original title's pun, it has replaced it with something that gives a completely wrong impression regarding the content. Indeed, as the article mentions, it "makes it sounds like a piece of molded plastic your insurance would refuse to cover".
Let's remember that "clickbait" once meant psycho-tricks like "You won't believe these 10 reasons why...". Newspapers have, since time immortal, used all sorts of literary devices in headlines. Indeed there are some publications where headlines are the only outlet for a bit of lightness. The economist, for example, is well-known for bone-dry articles in contrast to evocative headlines (and, sometimes, outright silly captions).
I'm all for superhuman enhancements, and I know that defence leads research in many areas, but I can't help feeling a bit disappointed that my friend will likely never have access to anything like this.
I'd expect such assistive devices to hit the medical market pretty much instantly once they are practical in terms of things like weight, cost and run time.
Because of that, I expect that fitting this to a body is a lengthy and, hence, fairly costly affair.
It's really heartening to see what's becoming possible for those with disabilities, but as other commenters say, the next challenge is making good solutions available.
A 100 lb nurse needs a bit of assist to move a 300 lb patient out of bed.
I'm guessing after some quick math that its not the water like I originally suspected but perhaps the armor and ammo but maybe not?
As the threat facing British soldiers has changed so has the composition of body armour, which now consists of front, rear and side plates designed to protect soldiers from small arms fire and IED blasts but weighs around 40lbs.
In addition to body armour, a typical soldier on patrol in Afghanistan will carry: a weapon (10 to 20lbs); radio, batteries electronic equipment (40lbs); water (10lbs); ammunition (20lbs); Javelin missile (25lbs). Soldiers will also be required to wear eye, groin, ear and knee protection as well as gloves and a helmet
What's the hard part? Aligning to your leg? Powerful enough motors? Software?
Yeah, it's called a squat rack.
It's interesting to wonder if government special ops teams are encouraged or even required to follow doctor-prescribed PED cycles these days.
My point is that PEDs really do take you to a different world physically, and there is zero - zilch competition between natural and enhanced athletes. When you are at that level, it's difficult to come off, go back to fatigue and weakness and small size, so you end up blasting for a decade and at that point your heart is the size of your head.
HOWEVER, some teams will go the extra mile and take Amphetamines during deployment's to help with performance during ops.
