A photograph of a short-eared owl mid-flight was the last Instagram post biology professor Carl Bergstrom shared before announcing his departure from the platform Jan. 10.
Or know how. Just because they are scientists doesn’t mean that they are necessarily particularly computer literate. I once had to explain to a university professor that wireless electricity doesn’t exist, and the Wi-Fi is only for internet. So yeah.
Well there’s two possible implementations of wireless power transfer.
There’s the way we use to charge our phones, Which is just an electromagnetic effect with no real way to extend its range. That technology has progressed as far as it’s ever going to get.
The other way is through power beaming using infrared lasers and special crystals. That technology does have potential but is nowhere close to being consumer ready yet. One day a router may include both features but not today and certainly not in 2016 when this happened.
People have been able to extend the electromagnetic effect to a few feet, but yeah, there’s a reason why most just use the close range version we have today.
Microwave transmission has also been explored in addition to lasers, as you say, but either way both methods involve power loss in energy conversion, and they both are very directional, making it impractical for consumer use.
But anyway, just wanted to say that the tech technically exists since it’s funny when normal people bring it up without knowing the limitations of current technology and physics.

I mean, wireless electricity tech does exist, it just sucks and is horribly inefficient at any reasonable distance.
