> Soldiers now can even see thermal figures through walls or solid materiales

I have a thermal imager. They can't see through walls in the sense you're imagining. If there's an electric heating element inside a wall or a ceiling, you could get an image of that. If there's a camera or other active electronics hidden in a wall or object, you can see the heat from that.

You wouldn't be able to see a person in an adjacent room through the wall between the two rooms, unless the wall was made specifically of thermally-transparent material.

I've heard rumours of "see through walls" equipment in the US military before. If they really have something like that, it would have to be using technology other than thermal imaging.

> At least in America, high-tech scans are treated as a cash cow. And cheap & reasonable tests, if done, are merely an afterthought - after the patient has been milked for all the scan-bucks that their insurance will pay out.

Maybe it's a regional thing, but that hasn't been my experience. I've had one MRI and one CT scan in the 25+ years that I've been a full-time employed adult with insurance.

I'd have been happy to sign up for more so I could have proactive health information and the raw data to use for hobby projects.

If I ever have a house built to my own specs, I want to get the best of both worlds by using drywall, but with most/all of the interior walls being maintenance corridors accessible via concealed doorways. A modern version of the way the dormitory in Real Genius was constructed.

Just make the house itself ~10% larger than it would be otherwise, so the usable floorspace is the same.

Adding/repairing wiring and plumbing would be easy. Every wall could have two layers of thermal/sound insulation. And who doesn't love secret passages?

Looks like it's improved even further - I'm seeing that model listed with 512x384 resolution, and it's $300 on Amazon.

Pretty incredible! I felt like I was getting an amazing deal when I paid about $1000 15 years ago for a FLIR E4 that I could flash into an E8. I might finally retire that in favour of one of these.
