Harry,

Have you ever looked at what happens to the efficiency of a CCGT if you ask it to ramp its power up and down rapidly - for example when the wind drops or rises?

[John Rumm]

Of course it relevant. If you are attempting to meet ever lower CO2 emission targets, then switching from coal to gas will help achieve that.

[The Other Mike]

You also increase gas consumption, at a peak time, increasing the chance that those on inerruptible gas contracts will lose supply.

Domestic Micro CHP, if rolled out on a large scale would quite likely reduce electricity demand off peak altering the loading deloading profile such that generating costs by 'big gen' stand a big chance of being increased due to less run time and lower loading.

The sooner amateur theorists, politiicans, greens, foreigners, and speculators stop interferring in the UK energy market the better. Nationalise the lot. One domestic tariff, one commercial tariff, one industrial tariff. Remove all wind turbines returning the landscape and seascape to how it was intended to be, remove all renewable subisdies (retrospectively and make the bastards pay back all their FIT payments) Ban all fossil fuelled generation closures, build 50GW of nukes, 20GW of coal, burn greens and all their families at the stake, shoot enviromental protestors on sight. Impale their corpses on spike in parliament square with a permanent webcam feed into every home, school and university.

Make FoE, Greenpeace and any other green loving band of fuckwits prescribed terrorist organisations. Remove all funding for climate scientists and stick two fingers up at the EU and the reducing emissions fallacy.

But heavily restricted or banned by RoHS for use in millions of end applications except it's permitted at an unlimited level in solar panels*

Why should greens get exemption from polluting my planet just because it suits their landscape destroying economy destroying cave dwelling for everyone shitty agenda.

Reusing the cadmium could be useful, maybe to make batteries to store power from wind turbines for use during blocking high periods

Sorry, that was a back of envelope calculation f*ckup, it's even worse as it should be 1.5 *billion*

30GW PV installed in Germany as of 2012. 80W Panel I have to hand (non grid connected) contains around 4kg of glass 30 x 10^9 / 80*4 = 1.5*10^9

[The Other Mike]

There is around 1GW of non pumped storage hydro in the UK at the moment, 2.8GW of pumped.

The only solution, the final solution as some have called it, as discussed here many times in the past, is to build a wall around Scotland, around 100m high and flood it. Oh for the day when the flood gates open, and Alex Salmond is pictured wearing concrete wellies waving a saltire as he disappears forever.

[John Williamson]

The important bit is the amount of cadmium in the glass, which probably totals about 2750 tonnes for 30 gigawatts.

[harryagain]

Most of the German panels are silicon not Cadmium Telluride.

[harryagain]

And our Mike knows better than all of the above? You are full of ignorant crap.

[Capitol]

Fortunately he's right.

[Johny B Good]

I'm trying to work out which part of:-

"Running a micro CHP system in winter actually reduces your net CO2 contribution since you're burning, to a very close approximation, the same amount of gas that an 80% efficient boiler would have used"

Wrong! Domestic micro chp will help smooth out demand by reducing the peaks which necessitate turning on the "Big Tap" at the Ffestiniog and Dinorwig PSP facilities which the National Grid have to pay for at premium rates.

A laudible aim, but why stop there with re-nationalisng just the PSUs? We may as well re-nationilse the water, gas, railways and telecoms industries whilst we're at it. All services that are vital to the wellbeing of the nation and legitimate targets for government control. All we have to do then is to collectively give a shit about corporate interference to the function of government and we'll have it made.

Ok, I'm with you there. You haven't lost me yet...

Ah! Now you're into the realms of fantasy...

This is where your fantasy takes a rather strange turn. I'd have specified "Upgrade" existing coal and gas fired power stations to LFTR and build more LFTR power stations to meet the shortfall in rising demand for cheap electricity[1].

This now reads like the ravings of a deranged mind. Hint: we can all see your 'thoughts', this fantasy isn't private anymore. It's as if you were thinking out loud but forgot to stop typing.

It makes you look like a young child throwing a tantrum on being confronted for the first time in its life with the reality of injustice. I do feel for you, Buddy, but for me and most adults, it's really, realy 'Old News'. Get over it!

na, just laying bare his position as a moderate ;-)

[harryagain]

You are barking mad. Living in some fantasy world. The days of cheap electricity are gone, only to return if nuclear fusion can be made to work. And there is a strong probabilty that will be abandoned.

[harryagain]

You are easily taken in by cheap propaganda. All these people are gonna be out of a job pretty soon. They are deperate to get their snoutsback in the trough.

Its only expensive because we are being forced to use expensive technologies to generate it. If it weren't for the interference of people like you who believe the cr@p you keep spouting we would still have an excess of generating capacity, and no green subsidy to push costs up. Just remember that despite all what you say there still isn't a single model that actually shows global warming is caused by CO2 or that the predictions are at all reliable. All you have is that CO2 is a green house gas so it must be causing the warming and will continue to do so with no actual *verifiable* evidence that its true.

[tony sayer]

In the meantime your spouting out of date bollix and thus far have not suggested a practical alternative source/s of power that will be workable on the scale required...

[harryagain]

There's tidal power aplenty in the UK. And still plenty of room for efficiency.

[Dave Liquorice]

Where? Show me the tidal power stations within the territorial area of the UK. What is their total and mean capacity?

[John Williamson]

He can't even come up with sites that can theoretically produce more than a couple of gigawatts continuously, while destroying the local wildlife habitats.

[Vir Campestris]

Well, one site won't. You need two carefully chosen to get continuous power, and then they can easily do more than 2GW.

With a big fat grid between them... we might get 10GW. That'll really help :)
