Sorry for the belated response; I would guess that it's more likely to correlate better with the surface area of the particles. My guess is based on nano studies I did a few years ago - start perhaps with work by the likes of https://en.wikipedia.org/wiki/Jacob_Israelachvili if you're interested.

But the most recent example I saw yesterday whilst doing some garden planning: https://www.rhs.org.uk/advice/profile?PID=620 explains about the importance of surface area of particles in clay soils.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255317#Comment_255317 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255317#Comment_255317 Mon, 06 Mar 2017 17:26:34 +0000 Ed Davies

"The contribution from the category covering combustion in the residential, public, commercial & agricultural sectors has increased over recent years and peaked in 2013 at 51 kilotonnes PM 10 and 50 kilotonnes PM 2.5 . In 2014 there was reduced fuel demand in the domestic sector but consumption increased again in 2015 and estimated emissions from residential, public, commercial combustion were 48 kilotonnes for PM 10 and 47 kilotonnes for PM 2.5.Most of the emissions from residential, public, commercial combustion in these last 3 years – 79 per cent for both pollutants - are from the use of wood as a domestic fuel."]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255581#Comment_255581 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255581#Comment_255581 Sat, 11 Mar 2017 17:39:06 +0000 DamonHD

This was merely an interesting thought that popped into my head which I wanted to write down and share.

Partly provoked by you, Ed!

An app that prevents or delays charging during peak times would work for me.

It is small amounts of power but in huge numbers.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255642#Comment_255642 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255642#Comment_255642 Mon, 13 Mar 2017 10:02:58 +0000 ringi
If the grid was more self regulating on the demand site, it would be possible to put more renewable on the grid without being as concerned about how the renewable are controlled. A lot of this work is more about enabling renewable to be added to the generation mix, than it is about reducing current CO2 output, from the current generators.

However we have lots of diesel generators that operator at the times of high peak, so reducing the highest peaks do have a direct benefit. For example a lot of hospitals are now paid to run their emergency generators at peak times, so they take less from the grid – much better for my washing machine to delay the wash.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255646#Comment_255646 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255646#Comment_255646 Mon, 13 Mar 2017 11:18:11 +0000 goodevans https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255650#Comment_255650 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14429&Focus=255650#Comment_255650 Mon, 13 Mar 2017 12:30:46 +0000 Ed Davies https://www.theguardian.com/business/2017/mar/13/uk-households-unnecessary-power-capacity-energy-climate-intelligence-unit-report

“The ECIU said that reserves could be more affordably secured through energy storage, greater interconnectivity with Europe and smart technology to help reduce demand from big energy users at crunch times.”

And never mind the transmission system and generation, DNOs tell me that they feel unloved and unnoticed, and they have to cope with the peaks of demand and microgen.

The National Grid defended the reserve scheme as a cost-effective insurance policy, and added that the winters had been mild.

Half hourly charging would do it on its own. Ideally coupled with smart switching on and off and this can be done by web linking without smart meters.

IF smart meters could do smart things then I might change my mind about them.]]>
