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.
hahaha... it saddens me that only those >30yrs old may get this.
You know what the world doesn't need?
an AI model trained on the old Reddit Hive Mind.
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.
You could say the same about C and D batteries too.
They're all 1.5V
