Comment Re:Enhanced bluetooth, and legacy standards (Score 1) 79

The *ONLY* clock in my house that I ever have to set is the one on the oven and that is because nobody makes an oven with a LW radio clock. I would have preferred an oven with a timer that if you didn't set the time didn't show anything, but apparently nobody wants one of those. Regardless on Sunday morning I will wake up with all my clocks all showing the right time within the second without me lifting a figure and none of them are connected to the internet (well apart from the computers and tablets and phones) and it's been like that for years now.

Anyway I am sure you could use some IoT power socket things and a raspberry Pi to rig what you want up.

Right because fully waterproof to IP68 3.5mm jack sockets have not been available for years already?

Sony have been doing waterproof phones now since early 2013 at the latest with waterproof jack sockets that required no plug and/or cover. By the time they got to the Z5 they even had waterproof microUSB sockets that don't need a cover as well.

The claims about needing to do it for waterproofing is just utter rubbish that Apple fan boys lap up because they don't know any better.

It's the same with most things like this it only gets more expensive in real terms over time. So yes in the long term it is cheaper to lay the fibre now than it is in the future.

Something else to bear in mind is that the OpEx for fibre is a lot lower than the OpEx for copper based solutions. Basically there are no power hungry electronics in the middle to go wrong with fibre hence it is cheaper to run by a *LOT*.

Usually old gas pipe was steel/iron. What they do is push some plastic pipe down the existing pipe, then blow hot air under pressure into it. This causes it to soften and expand so that it takes the form of the existing steel/iron pipe. The existing pipe can now safely rust away. At least this is what they do in the UK.

and in the process of invading Ukraine.

Still? Wow it's taking them a while. Which units are invading Ukraine? As far as I know, all that happened was Crimea acceeded to them. And they may have indirectly supported some rebels in Donbass, but hey it's not like NO ONE ELSE ever supports "moderate opposition" anywhere...

Are you actually asserting that demand is level 24 hours a day?

It can come very close.

In California, for example, a very large part of the demand is pumping water through aquaducts. By placing reservoirs along the way and doing most of the pumping during times of low electrical demand, California electrical utilities used to be able to keep the power demand nearly constant - and can still keep it much more level than in many other places.

Also: Coal plants can provide baseload, while wind and solar together do a great job of shaving peaks: Higher wind corresponds to higher HVAC load as well as higher generation. Solar not only tracks the air conditioning requirements but also comes close to tracking the daily load peaking - and solar plus wind tracks it even better, since the lake effect makes an afternoon-through-evening hump in wind generation.

at a power output proportional to the CUBE of the windspeed.

is this relevant somehow?

Yes, very. The steeply up-bending curve means that wind generators that are able to make use of high winds - which only happen for a tiny fraction of the time - have a peak power rating far above the average power they are able to produce in normal winds. So the peak power vastly overstates their average contribution.

The power can be stored,

The issue is not that the power can be stored.

The issue is that power capacity comparisons overstate the total amount of energy you get out of the renewable generation equipment over the long haul because coal generation can run near capacity all the time and renewables (excluding water power) only a small part of the time.

I'm quite supportive of renewable energy. (I'm a major participant on one of the renewable energy tech discussion boards, too.) But while it's very GOOD that renewable power has passed coal in power capacity, even with near-ideal load-levelling storage, it will take about another factor of three before it surpasses coal in providing usable energy to the loads.

... they overtake coal for amount generated per unit time.

Renewables may have higher total peak, but coal plants have level output and can run 24/7, while sun is only about a third of the day and wind varies with the weather - at a power output proportional to the CUBE of the windspeed.
