"Those inventors surely knew their devices were frivolous though, right!? Back when everyone was used to working with their hands, any small knife got the job done just as quickly :)"

"These tools are always good to have around, they're just the powered verion of the beat up old bastard file in every toolchest :)"

"Exactly! I think a handle at its' centre of gravity is actually a good idea though, to keep it from falling or to hold it back when it tries to do something it shouldn't."

"I've always been curious how ergonomics will change in lower 'G'. Will comfortable chairs be necessary on Mars, or especially the moon? Will people end up still really wanting foam padding, back rests, or chairs at all for that matter, or will a simple stool and/or standing workstation be all you need in low gravity?"

"Apart from the obvious safety issue, does this design actually help you take photos? Cameras don't have recoil, and (usually) aren't as long as a rifle. I suppose bracing the camera against your body helps with reducing movement, but it also limits your ablity to see the display, and angle the camera as mentioned above.Maybe futuristic recoilless laser guns will look like cameras some day! "

"I would love to hear more about how might "automatically detects distress situations at sea". I'm sure it's difficult for human lifeguards to tell sometimes if someone is in danger or just a clumsy swimmer."

"Bagged milk has always made some people uncomfortable, preventing wider adoption, I suppose. This partially addresses that issue at the expense of more packaging than the existing system of just putting the bag in a reusable container."

"It looks like you'd be able to propel yourself around much more easily with the individual kneeblades, like the difference between using skis vs a snowboard on flat ground."

"Either googly eyes, or have it look at you with the Cylon death stare:https://www.youtube.com/watch?v=faukADr0_6g"

"It's a more complicated calculation based on where you live, how your power is generated and how natural gas is delivered to your home. the Green house effect of natural gas is sometimes double what you get from burning it, due to leaking methane (called fugitive emissions). These leaks are often at the point of consumption, aka your gas stove. Environmental decisions are complicated!"

"If this included an attachment for a (replaceable) actual visor for eye protection, it would essentially act as a PAPR style welding helmet. I'm not sure what use case they have in mind, but an all in one safety system for woodworking that's not as sweaty and cumbersome would definitely sell. "

"Can't wait for that second to arrive! :)"
