In the winter, it keeps hot things hot and in the summer, it keeps cold things cold.
How do it know?

Cell Phones = Communicators from Star Trek
Tablets = Triquarters from Star Trek
Totem Cams = Wall Climbers wet dream
But I will say that Remote Desktop technology, whereby you can get on another machine from the machine you are on with full visual representation of the desktop, is pretty outstanding.

The inertia of eighteen thousand tons of steel idling on
the ocean’s surface was a massive force unto itself, but it
was no match for the magnetohydrodynamic engines.
The cryopumps spun up and went infrasonic as they pumped
liquid nitrogen around the magnets that stripped free
electrons from the water forced through the drive tubes.
A creaming, explosion of froth erupted at the Oregon’s
fantail, and within ten seconds of Max’s command the big
former freighter was moving....
With the ship under way,
the passive sensors were deaf to everything except
the noises the Oregon herself produced, the shriek of her
engines and the building hiss of water against her hull.

Testla's invention has been commercialized as disk pumps. The efficiencies are relatively low (50% or less),but it works well for high viscosity fluids or ones with lots of entrained gas. A small niche product.

A variation is the vortex impeller wastewater pump, applied where you need a relatively small pump that can still pass turds, dead cats and rubber duckies without clogging and you aren't too concerned with efficiency.
Teslas' claimed efficiencies only come at impractically high rpms.

^And if you need to keep it clean and dry use the more modern laser.
In this study, we create a multifunctional metal surface by producing a hierarchical nano/microstructure with femtosecond laser pulses. The multifunctional surface exhibits combined effects of dramatically enhanced broadband absorption, superhydrophobicity, and self-cleaning. The superhydrophobic effect is demonstrated by a falling water droplet repelled away from a structured surface with 30% of the droplet kinetic energy conserved, while the self-cleaning effect is shown by each water droplet taking away a significant amount of dust particles on the altered surface. The multifunctional surface is useful for light collection and water/dust repelling.

yes in fact three sizes and they are the only 'nut' that allows for finger tips to fit in the same small crack at the same time as the protection.
these and knife blades were go to thin gear, often the only gear
the things that started the 'change'1st gen. GriGri izz
.replaced this, the Robotthe Grigri is great so is the Wall Hauler
the Robot does Both of the same tasksbetter? no grit grind,With two the options are exponential some don't like the sharp edge and wear factor For safty sake and ease of use they need to
`Be paired with a cordelette, passed thru that hole in the sliding brake bar

while not as versatile, (no hole to unlock , back up hauling ect.)
I think I'll be getting one of these!

This must really piss off Tesla's ghost.
The Pacific HVDC Intertie. Almost 900 miles of million volt direct current
twin conductor wire from the Columbia River to Los Angeles.
Long distance point to point HVDC transmission schemes generally have lower
capital costs and lower losses than an equivalent AC transmission scheme.
Thomas Edison vindicated! Oh yes!
