Quietly and seemingly out of sight, governments, private investors and mercenaries are working to seize food and water resources at the expense of entire populations. These groups are establishing themselves as the new OPEC, where the future world powers will be those who control not oil, but...

Voyager 1 Is Back! Legendary Probe Makes Contact From Interstellar Space
A friendly voice we've been longing to hear is drifting back to us from interstellar space, 24 billion kilometers away (15 billion miles).

!5 billion miles away, a 47 year old broken computer has been sent a work around so that its dud chip can be ignored and the message processing is corrected.
It's tiny 23 watt signal is still getting through albeit that the data rate has now been slowed to 40 bits per second so it can be detected by massive dishes at Goldstone and in other locations depending on which part of Earth is facing the space craft at any particular time.
Then why does my mobile phone signal keep dropping out when I phone my friends? I have a dish on the side of my house too.Voyager 1 Is Back! Legendary Probe Makes Contact From Interstellar Space

Might be because your phone's battery is shagged out and can't supply enough continuous current for the chipset to juggle lower bitrate codecs for lower/fluctuating signal during long calls. Your phone might also be doing a huge number of other things at the same time. In my case, the phone is recording all phone calls, which is an additional overhead. I'm thinking of replacing my old phone's battery for that reason, while new replacements are available - won't do any good if network operators drop long calls during busy periods as a matter of policy, while advertising "Unlimited" minutes in call packages. Bit like when the likes of Virginmedia broadband advertises "Unlimited" downloads, but then aggressively shapes traffic, the brigands.

Tell me about it..... People constantly can't get through to me unless I force my phone to only connect to the base station with 2g. I live in a hollow, with no line of sight to any antenna mast. 2g is low bandwidth. It passes data at a low bit rate, which makes the connection much more robust than high bandwidth, fast data rate comms.
If you can't connect, try in settings on your phone forcing 2g connection. That will depend on your provider though. Some like '3' only do 3g/4g and 5g. All of them are data hogs. On my android phone the option to change the mode is under settings/connections/mobile networks/network mode..... Try it.
Voyager is now running about 40 bits per second
4g runs between 8 and 10 million bits per second
3g runs 1 million bits per second
2g runs 30 to 50 thousand bits per second
The less data you are passing over the link, the more solid the connection even in weak signal conditions.
It's not rocket science - even if it nearly is.
Don't try connecting with 5 g unless you are right next to the base station. It runs speeds as high as 100 million bits per second. More data means you must have more signal strength.
I run a hobby, amateur radio, low power radio beacon at 1.4 bits per second. With 2 watts out - about the same power as a mobile phone, I can regularly get picked up in Australia. The only reason it works is that it is VERY low data rate and computerised radio receivers can find the signal in the noise.

Talking of radios, here's a funny anecdote. Members Saneagle and D8veh were out for a ride and enjoying their new communication with their Maplin 2-way radios.
Riding along a nice lane deep in the countryside, the radio silence was suddenly broken by: "Up there under the bushes. Get the dogs quick. Push, push push."
We looked at each other for a bit, then Saneagle presses his PTT button and says:
"Alpha 1 to Alpha 2. I think I've spotted them up the hill by the bushes with the dogs"
Daveh: " Alpha 1, Alpha 2. I'll sweep round from the South and try and cut them off if you can attempt to intercept from the East"
We didn't hear any more, as we continued pedalling up the road. In fact we could hardly pedal because we were creased up with laughter.
We've no idea who it was or where they were, but we assumed that there were some guys panicking somewhere doing some cruel illegal activity with dogs. Range was only a couple of miles, so they might have been nearby somewhere.
Bet that put the frighteners on them.
Those radios are rather good for the tiny money they cost.
I got some for my eldest grandson. They worked a treat. Thirty eight years ago I bought some for my own sons, they were terrible by comparison and cost a lot more. They didn't even have a proper receiver. Some sort of regenerative nonsense designed in the 1920s and re imagined with a single transistor.

Apple supplier says new tech has 100 times the capacity of its current batteries.

current best e-bike cells like the 21700 5000mAH has a volume of 24cm3. You can easily estimate the density of it in WH/L: 5WH*100*100*100/24=208WH/L
by using prismatic cells, the volumetric density can reach 250WH/L.
