    When I first broke my neck and had a spinal cord injury when I was fifteen one of the things used to combat pressure and bed sores was a bed which utilized very similar technology called a Clinitron Bed. You literally floated with no excessive pressure points anywhere. I also saw they were utilized in severe burn injuries as well as multi-extremity infection and swelling. I know for me it initially saved my skin for the five days I used it until my traction achieved reduction of my two fractured cervical vertebrae and I was stabilized for my surgery. When I awoke I used a RotoRest bed which rotated from flat to ninety degrees and then back the other way to promote the exchange of fluids in your respiratory system. Anyway it was a brilliant invention and one that I know back in 1986 cost my BCBS insurance over $1,000/day which back then was HUGE!

    This seems a lot like something I've been looking for. Can you replace gravity with an elastic skin, and replace the sand with something with enough friction that you can pose or mould when it's fluidized, but otherwise have it retain its shape under the tension of the skin? So that you have something you can turn to putty with the flick of a switch, and then lock in place by switching it back off again?

    1st off, love this video. So fun. I saw this a couple of years ago, and I come back to it frequently. Anyways, there are a bunch of videos on sand batteries on KZclip these days. Trending with all the other alternative energy options. And I thought of this video. Wouldn’t it be great to combine the two ideas. My thought is along the lines of heat pumps. What if the heated sand could be moved, stored, and then moved again to transfer the energy. What better way to move sand than to have it in a liquid state. Food for thought.

    Is it possible to scale this up further? Like could you make a "sand row boat" where you could make a boat float over sand dunes as you go? How hard would it be to scale it up further and also find a way to make the compressed air manually? I think you see where Im going with this. Could the pyramids have been made this way as far as stone transporting.

    This guy has the coolest job on the planet. All because He is educated and super smart. There’s tons of people like this that could do all of these things but he was smart enough to put it in video format like this on KZclip. I wonder how much this guy is worth.

    I learn more and am being entertained more by a man who uploads once a month than my chemistry teacher, who I see 5 days a week.

    Registered nurse here. We actually use this technique in specialized hospital beds that use aerated sand to reduce the friction and shear that causes pressure ulcers. Think of a water bed but filled with aerated sand instead.
