I read once that it needs the output of a power station to supply all the items left on standby.

That may or may not be true but why do so many folk (most) leave things on standby? And no, you don't  need to leave your Sky box on nor your home network overnight if you are not using them.

 

I was reading a home tech forum earlier where a guy had a home cinema system that was turning itself on, very loud, to a radio station in the middle of the night. :unsure:

The shop he bought it from couldn't help, nor the manufacturer who did look into his problem but couldn't help either. Other forum members were offering a plethora of other possible solutions but none had worked.

At no point was it suggested he simply unplugged the bloody thing. That would have cured it. I don't think it occurred to anyone to suggest that because of this 'standby' culture.

Well, an agreement was reached.

 

I fear it is too watered down and compromised on, though. The Earth and the laws of thermodynamics don't much care about human wants.

Seems a bit of a waste of time. 2 weeks of celebs and politicians flying about to have to come back next year to do it all again.  

Wish they were honest in how much money this is gonna cost the British tax payer.

I agree that it would be better just to simply do things.

 

However just as an addendum the consequences of climate change if left unchecked are of a magnitude no amount of money can pay for, whether or not it's the UK taxpayer or anyone else. Money isn't much good when a billion people are bereft of food, potable water and a home as a result.

Plus, the British taxpayer can grumble now but wait until the sun belt of the world really heats up and you've got the best part of a billion people (as noted above) all trying to get somewhere else. 

 

The UK is the most overpopulated (per land mass) country in western Europe. We're also the only one projected to have an increase over the next 30-50 years. 

 

Mark my words, these people will be (somewhat rightly) turning up at our door in 30 years' time. I am genuinely starting to dread getting to retirement age.

Yep, and the door of every other still temperate nation.

 

How, exactly, will that be greeted? With open arms - or with weaponry?

I read a stat somewhere that the digital clock on your microwave uses more power than you use to heat things up, it depends on how much you use your microwave, but I can see a grain of truth in it for some.

It's not just about taking little measures here and there to conserve power.

 

It's also, more importantly, about changing the way we generate that power in the first place so those cutbacks aren't as harsh as they might otherwise be.

really? Lets say 5 watts per hour to run the clock - 120 watts per day. 840 watts per week. 1 kwh every week and a bit

 

https://powertothekitchen.co.uk/do-microwaves-use-a-lot-of-electricity/    suggests 5 watts as a guide - all I could find.

 

800 watt microwave - approx 1200w per hour of use

If you use it for less than 40 mins per week....

What the hell were the Russians thinking? As Mr Amos says, it's insanity to risk the lives of astronauts and the future of human spaceflight by toying with triggering Kessler Syndrome like this.

I've often wondered what the after effects would be on us sending up satellites for so many decades - just googled Kessler Syndrome and it makes a lot of sense - before anymore get sent up are they thinking of ways to remove them when defunct?

Well, there are what is called "graveyard orbits" that satellites are supposed to be pushed into when their useful life is over, rather than requiring the additional time and fuel to deorbit them.

 

Unfortunately, these procedures can't be or aren't always followed.

The map of the debris that is up there and big enough to be tracked is quite alarming. And that's before you even get to the smaller stuff we can't see. 

 

Something like 27,000 trackable objects according to NASA. 23000 of those bigger than a softball.

It is alarming.

 

Our future depends on us getting out there, and at some point we're going to have to come up with a solution that involves either clearing that debris or hardening craft so much that they don't notice it, both of which are daunting from an engineering perspective.

Boggles the mind - China and India should be in a position to lead the way on renewables. They can even use it as a high horse to beat the west with. "We built all your shit, now look at us doing the right thing" - it's textbook Communism govt but they don't.
