Yeah, have you seen the size of those? Those are chem lasers in order to get the wattage needed to destroy something.
Plus you need the electronics/mechanics to track the device perfectly to keep the laser on target in order for it to do damage.
All completely unnecessary to drop a small drone out of the sky.
Nah, lasers too big. It would be a simple birdshot shotgun. Its detection and aiming.
When they are high up, they can be hard to spot and hear.
But a pair of sensitive mic’s and a camera designed to look for them could easily be paired with some AR glasses.
What sucks is that us hobbist’s can’t get FPV, motors, ESC’s, or batteries at reasonable prices (if at all)
The reality of it, is this is short lived.
Anti-Air meant for small drones like this is coming and soon.
And it will shut these down quickly.
Yeah, that isn’t going to work, because either

hahaha… it saddens me that only those >30yrs old may get this.

government regulation to force companies to begin using a modular system
Yeah, that’s fair. But the issue is also similar to cell phones.
Each battery is unique because it needs to fit the unique layout of the vehicle. Not to mention the battery tech is moving so fast, that the chemistry of the battery itself is changing every few years.
I suspect China’s approach to a vehicle where you hot-swap the batteries instead of charging will be the way it goes. Someone will do it, it will be most $$$ efficient and therefore profitable, and then it will force them all to adopt the same approach.
The replacing the battery is simply a supply issue.
There is such a demand and so little supply, that if you want to buy just a battery (and not the entire car) you are out of luck. They’ll put that battery in a new car and sell it before selling it to you as a replacement.
But that’s short term. There are a huge number of battery plants already breaking ground and coming online.
In 2 years or so, the price to replace the battery will be a HELL of a lot lower, and the issue you linked above will be long gone.
I can now finally solder things easier.

Stuff with motors are, like air con and refrigerators. Those are better left on AC.
No. Trend is they are all showing up with frequency drives. Of which those inverters are rectifying to DC before making their own AC.
Efficiency gains are massive of a frequency drive , hence why they are doing it.
Would be even better if they could drop the first rectifying circuit and just use the inverter portion only.
You lose very little by rectifying AC
You lose a lot actually in all the small cheap rectifiers that are in every device in the house.
Where a single purpose designed FET rectifier that is built for efficiency at the breaker would be drastically better.
You wouldn’t have to.
Every device instead of having an expensive PD communication device in it, would have an even cheaper PWM DC Step-down.
No communication needed.
Each device would just draw what it needs to.
_ It wants 3.3V, or 5V, or 12V, or 48V, or 18.7V,
Exactly
That’s why if you had a 110VDC supply at the wall, you do a simple PWM step-down to the required voltage in every device.
LOADS cheaper/efficient than any USB-C PD circuit…
Saves on transformers, saves on dozens of USB PD wall outlets, saves on communication needed to communicate the PD required between each device and every USB PD wall outlet.
Much cheaper. More efficient.
If only the wall was 100VDC instead of AC
No, AC requires large heavy transformers and then rectifying.
DC dropping down to a lower DC is way easier and more efficient.
Well, I mean if you don’t understand power electronics I don’t see how you can make that statement.
What?
Most vaccums are brushless, where they are already converting the AC to DC internally. Your vacuums would be cheaper.
Where would I recharge batteries for my lawn care equipment?
again what? The same way? Your charger is converting AC to DC. You could skip that step.
All of these appliances would work better/cheaper with a 110VDC@15A source.
powerful DC-DC
No, are you not aware how these work?
A step down DC-DC is nothing compared to a transformer rectifier or PD electronics with communication with a USB-C.
again, simpler and cheaper electronics for everything
PWM DC to DC dropping voltage to what you need is easy/cheep.
So instead of a big transformer + rectifier that each device has now, it would be a much smaller/cheaper step down at like 99.8% efficiency
Yeah, but frequency drives/inverters were still pretty pricy things back then to for high powered motors for compressors/blowers/etc.
But the cost and efficiency of those things have dropped SIGNIFICANTLY in the past decade…
