There are no absolute numbers in here. How much charge can it hold? How does that compare to an AAA battery? How long can it hold the charge and how does it compare? What dimensions would it need to have to store as much as a AAA battery? What's the current projected price?

I can't wait to see this technology in motorcycles and micro mobility vehicles. It will be a mushroom in Mario Kart IRL. And imagine this tech on drag bikes/cars

Unfortunately the technology will also be used for creating new weapons of war.

I wanna see some even more insane FPV drones. theres always some battery breakthrough though, so I don't wanna get my hopes up.

I wonder if we will get to a point where capacitor batteries will be too good.

Can you image a small issue leading to an entire instantaneous energy dump of a large capacity capacitor while on an airplane?

Make me wonder if we will limit how fast a capacitor can discharge in some consumer goods.

Yeah. Good thing we don’t fill up planes with flammable material today!

We already do with resistors.

[–] [email protected] 4 points 6 months ago

And fuses and breakers

I think we have more pressing issues in certain airplanes at the moment, but that's a good point.

Can't blow up the plane if it falls apart first

I really hope it leads to something no energy loss for regen would be GOAT

Although we don't see it, all of these developments do actually eventually make their way into battery tech. The batteries of today are not the batteries of 2014.

If you remember what battery powertools were like in early 2010s, it's super obvious how far we've come. The higher end things like battery powered lawn mowers didn't exist, and if you wanted real power, you needed a cord.

I mentally nicknamed them the twins. Two guys who worked together with their two drills. Each had a double sized DeWalt battery and another spare double sized. Last time I saw them was 2016. So yeah you got an acedotal backing you up.

Cord mowing has a long established tradition.

[–] [email protected] 7 points 6 months ago (1 children)

I mowed my grass with a corded mower for a decade until the motor bearing finally disintegrated. Cost me $100 and one blade replacement. No small gas engine was ever that reliable for me

[–] [email protected] 4 points 6 months ago (1 children)

Did you ever mow your power cord though?

[–] [email protected] 4 points 6 months ago

Nah, just zig zag away from where you plugged it in and it's never a problem.

I still remember that in the 90s till the 2000s you would get maybe 60 to 90 minutes of battery life out of a new laptop. Then it jumped to 4 or more hours thanks to better batteries, more energy efficient CPUs and displays.

[–] [email protected] 9 points 6 months ago

Laptops is a bad example. The improvements are moreso the chips and efficient hardware, not the battery

[–] [email protected] 11 points 6 months ago (1 children)

I just wish it was an either/or situation.

I don't always need my lawn mower/blower/weed trimmer on batteries. I wish I could easily plug them in when doing light dut work close to the house. But then they couldn't tie me into their battery ecosystem as easily.

[–] [email protected] 7 points 6 months ago

I've seen a Makita eletric brush cutter with an adapter to plug straight into a standard outlet. The person who bought the machine told me it was more expensive than a battery pack but at least it made the machine usable for longer periods of time when energy is available.
