Sliding charging ports on electric cars might be a good idea

Fixed by wireless charging.

Could you use lasers beams to charge batteries ?

or a high energy RF beam ?

A high energy RF beam made for charging could keep drones in the air for longer periods.

They need to be in line of sight wouldn’t they
I wonder if solar panels on the drone could charge a drone in flight

I wonder if satellites could be recharged by high energy lasers or high energy RF beams?

If you could use a laser to knock on one out then why not for recharging one ?

The exterior conductive metal of either a drone or a satellite could be designed to absorb a beam up to a certain energy level.

The same level needed to recharge the internal battery.

Well people have proposed such means to transfer solar generated electricity from orbit to Earth, so presumably it could go the other way.

Tracking technology has improved so much.

Its possible now to design a complete system

They’d have to be geostationary wouldn’t they

It might not matter, depends on the charging time.

and how efficient the technology can become

there will be losses, these will improve over time.

If all satellites had that capability then they could pass energy around to other devices in space.

Possibly even to eventually recharge Elon’s Tesla electric car in space.

It does a tiny battery to play space oddity on a loop.

Interesting discussion about lithium batteries exploding.

What sort of batteries do they put in satellites ?

Yes, but not because he comes up with off-beat ideas like these. The genius is in selecting the best, getting the manufacturing completed and selling the things.

I like the sliding wall electrical outlets. They so often interfere with furniture or don’t have sufficient capacity.

Woohoo. Death ray.

Yeah sliding wall electrical outlets are a great idea and will only increase the cost of the electrical installation by an order of magnitude.

Laser transmitters and laser receivers

How much energy can a laser receiver absorb ?

I like the pop up usb receptacles i kitchen bench tops

I would design a smaller one, that one is too big.

Shouldn’t electrical outlets been in awkward hard to reach places that require you to crawl under things or twist uncomfortable to reach them

I’ve had various ideas about TV stations.

A TV station that only screens 3-D movies, including only 3-D ads. You watch with red-green glasses that you can make yourself or buy.

A countdown clock to tell watchers how many seconds of ads are left. Either on the TV station or sold after-market using artificial intelligence.

TV ads limited to text messages (like Google search home page only allows text message ads).

Or TV ads limited to a single video camera shot.

>>>TV ads limited to text messages (like Google search home page only allows text message ads).

I like that idea. I have never liked the sound of TV ads due to sensory overload in hearing that I have.

Oh nowe I get it!

move Elon = move along

>>>A countdown clock to tell watchers how many seconds of ads are left. Either on the TV station or sold after-market using artificial intelligence.

That’s another good idea, then tv shows could be recorded with or without ads.

An invisible countclock as part of the transmission

Clocks are part of radio and tv transmission there for syncing etc

The recorder could look at the countdown clock for ads and know when to start the recording.

While another count down clock could be added into the movie to stop recording the movie when the ads come on.

That would need regulation, because they would never do it voluntarily

>>>I wonder if satellites could be recharged by high energy lasers or high energy RF beams?

what about using laser transmitters and laser receivers

Have a laser receiver built into the satellite and a ground station fires the laser at the laser receiver on the satellite

and recharge the rechargeable batteries that way

note this is when you want more power than what the solar panels can provide

How much are these sort of power rails being used?

Thinking further on this, I’ve figured out an algorithm to ad-block on free to air TV.

The algorithm would compress a video – audio frame on the fly, like a checksum, and compare it with the first frame of earlier ads. When a match is found, replace the ad with whatever the watcher desires.

There would be several ways to fool it.

• changing channels into the middle of an ad you’d see about half a second of the ad before it cuts out.
• where ads for TV programs contain a segment of that program, eg on ABC, the ad blocker may or may not suppress that duplicate part of the program, depending on how the ad was made.
• The first occurrence of the ad passes through the ad blocker. It only blocks the repeats of the ads.

But those problems would be negligible. The ad blocker would reside within the set top box or HDTV, to work independently of selected aspect ratio and mute button. Or could go between the set top box and TV if aspect ratio and mute button are not an issue.

mollwollfumble’s ad blocker for free to air TV. In pseudocode.
“alternative” is the the alternative program to play during ad breaks. eg. mute, play music, or switch between channels.

There are two processors:

• a synchronous processor that reads pixels from the aerial and displays images on the TV
• an asynchronous processor that finds the starts and ends of ads

Synchronous processor:

constants tol, tol1 set to 1%, 0.1%

initialise:
sumr0=sumg0=sumb0=0
previousframe=empty
blocked=false
option2=true ! block second occurrence of ad, if false block third occurrence of ad, user selectable

Get newframe {
start=false
sumr=sumg=sumb=0
For each r,g,b pixel {
sumr=sumr+r
sumg=sumg+g
sumb=sumb+b
}
if (abs(sumr-sumr0)>tol) {start=true}
else if (abs(sumg-sumg0)>tol) {start=true}
else if (abs(sumb-sumb0)>tol) {start=true}
if(not blocked) display previousframe
else display alternative
previousframe=newframe
}

Asynchronous processor:

On occurrence of interrupt start
start=false
startframe=newframe
for each knownad {
if (abs(startframe.sumr-knownad.sumr)>tol1) next
if (abs(startframe.sumg-knownad.sumg)>tol1) next
if (abs(startframe.sumb-knownad.sumb)>tol1) next
! found match to known ad
blocked=true
wait for next interrupt
}
! no match to known ad, start search for unknown ad
blocked=false ! innocent until proved guilty
for each oldstart {
if (abs(startframe.sumr-oldstart.sumr)>tol1) next
if (abs(startframe.sumg-oldstart.sumg)>tol1) next
if (abs(startframe.sumb-oldstart.sumb)>tol1) next
! found new ad
if option2 {blocked=true}
if (number of knownad = 10,000) {
delete oldest knownad
! replace with newest knownad (cyclic storage with a pointer to oldest)
knownad.sumr=oldstart.sumr
knownad.sumg=oldstart.sumg
knownad.sumb=oldstart.sumb
increment pointer oldest knownad
wait for next interrupt
}
! not a new ad
if (number of oldstart = 1,000,000) {
delete oldest oldstart
oldstart.sumr=startframe.sumr
oldstart.sumg=startframe.sumg
oldstart.sumb=startframe.sumb
increment pointer oldest oldstart
wait for next interrupt
}
