"Electrifying Heavy Machinery at RISE Robotics!"

Interviewer guy asked if there can be a pogo stick for a 1,000-lb person.

While the cylinder was moving at 100% speed without knocking rhe water bottle off the table's edge, my first thought was, "In a maritime environment with loss of electricity (EMP or just main and backup power failure), how would ship's force open or close watertight doors?

As for the batteries, they're lead. At seeing that, I instantly thought of the interview Ricky Roy (Two Bit da Vinci)

"Graphene is FINALLY Here - Energy Game-changer?"

Two Bit da Vinci


did with the makers of graphene batteries, which can work way, way, way below 0°C and start with plenty of power, replacing lithium batteries. So, will that belt-moved trailer liftgate. So, will it work in super freezing clines? Props for the device being far, far quieter than the traditional lump-motor ones that are noisy as hell, clang and bang the lift gate, and grate my nerves when it happens if I happen to walk by when a deliver is being done. Dome operators slam them to the ground, some to the truck rear frame.

I hope someone makes tech to get rid of the brake compressor noise coming off of trucks and ***especially*** transit buses. I always get a feeling of claustrophobia and shell-shock or PTSD when on buses about to move off the driver releases the brake, and a loud PTSHHHH kickis off. Why can't those damned things have a pre-bleed? It would save my ears. Strangely, few people seem impacted, or don't care, or they just resigned to the noise as somehow it's normal or ok.

I kvetched loudly about this around 2012 or 2014 or so, and someone said MUNI's buses are quiet(er). But, that was when some buses newer buses were being added to the fleet. If course, new buses' brake cylinders/compressor systems will be quieter. So were those of MUNI. But, rhe current ones truly unnerve me, and I have to gird and simultaneously plug my ears, and generate an internal hum, akin to the sound of being underwater, to woosh out the piston/cylinder noise.

I did years later while watching some YouTube videos notice, however, that buses in China, Japan, and Korea were as noisy or perhaps noisier.

Not brake-related.

But, in Tokyo, in 2005, in Yokohama, I almost got myself run over. I was walking too closely to the sidewalk, lost my balance (I was sober, mind you), and almost wobbled off the sidewalk as I also had some stupid temptation to just step down, then step back up. Something inside said, "not this time...", and suddenly, a super-silent Tokyo Metro transit bus shot past me as it approached the stop. I definitely was enough in the road that I would have been mangled beyond recognition.

It would not have been the driver's fault. It would have been mine. But, nowadays, electric cars have whirr/electrical-sound noise makers to help the blind and others gauge proximity to or approach of an EV.
