A cement works flue gas contains lots of CO2, from the calcined limestone and fuel burned, so would be a far better place to site this process. At least the heat for decomposing the limestone would have been part of the normal cement manufacturing process. I, too, think the whole thing is a stupid w...

I do check, on my car, that the journey distance agrees with that indicated by goggle maps (I often deviate from a goggle route to see if distance and journey times are altered by my modified route). I haven’t actually ever checked the increase in total mileage recorded - I’ve never needed to - but ...

I can't read that article, but have seen others on the subject. I recall the claimant saying that the car is clocking up 72 miles on a 20 mile trip, and this is because of the predictive algorithm used by Tesla for estimating range covered ......... :facepalm: That should equate to about three and ...

On the other hand there is still a huge amount of hype around offshore wind conferences and amongst recruitment agents, however I feel that the reality is different. I’ve no real comment on the industry position, but my obvious comment to the above is ‘‘what else would you expect from the examples ...

Don’t see many public chargers at 7p a kWh round my area? Great investment The comparison is with home charging! Those lucky (hardworking) enough to have a private driveway buy the fuel for their car at 7p/kWh while people who live in flats pay 39p. Hardly seems fair. Our neighbour is having a gull...

A far better record than one isolated “half-hour record” of solar generation, if applied/related to the monthly national (or personal) generation?

A single half-hour record does not really have any weight, regarding the percentage of anything. Spot readings do not apply to even a few hours, let alone the whole day. Good for new records, but minor record increments will always be welcome. Minor increases will eventually result in meaningful ren...

The only issue is the ongoing requirement of ‘spinning reserve’ for black-starts after widespread power failures. Nothing to do with how much or how little renewables are being generated. There have been umpteen periods over the last year, or so, when fossil burning has (theoretically) not been need...

I’m guessing they are including burning imported wood pellets/chips? I don’t count the subsidised burning of north american woodlands/forests as renewables.

But getting better all the time. More renewables means less fossils which has to be good.

Some of them use propane as the refrigerant? Doesn’t that mean it can be installed by non-gas fitters?
