I never really understood why battery technology was so difficult until a friend put it in perspective for me. The only difference between a battery and a bomb is the rate they release their energy. Now I understand.

This is similarly true to a container of gasoline. The difficult part is we've yet to find a battery tech that comes even close to the same energy density. Gasoline has nearly 12000 Wh/kg, compared to the 200-500 mentioned in the article.
Im curious what a regular size lithium car battery would release if you were to burn it
Not just energy density but also how quickly we can refill it.
I read this a bit ago. Hopefully all this tech eventually finds it way into aircraft.
My money "hope" is actually on smaller solid state batteries than can be recharged through the air. Similar to watt up tech and ossia.
With power over air you need less battery storage and work on keeping the battery from dropping.
Also I think best case scenario would be a massive reduction in the amount of planes flying.
High speed rail would be a better solution. Planes across seas and then rail travel on land.
If trains can get within speeds of air travel then we might be getting there.
Alas will be long dead before anything happens

Are you asking or ? What's the situation here ?
They clearly are. So, care to explain what "power over air" is?
Plesse don't let it be wireless charging...
It was
Thanks for sharing. I struggle with feeling such dread about the climate crisis. It's very helpful to see posts with positive stories like this. Such exciting possibilities for reducing fossil fuel usage and still having regular air travel.
There seems to be yet another new battery technology that will save the world every day. And yet, they never become available to the public. I really wish we could ban them from announcing until they can mass produce the battery and sell it to the public. It is almost as bad as all those articles about the "flying car that will be available next year" articles that have been appearing in magazines since the 1950's.
The issue is generally scalability. Lots of cool concepts but hard to mass produce profitability.
As this is Nasa, it's subsidized, but there should be even more government money going into energy storage as that is the biggest hurdle for renewable energy.
