Fed up of having to send complaints to the #BBC on its negative coverage on heat pumps to individual programmes, I have written to the Director General, Tim Davie. I haven't pulled my punches. #heatpumps #retrofit #heating #falsebalance

Silicon Valley UK?

The UK Chancellor has declared that he wants the UK to become the next Silicon Valley.

Hermann Hauser, when asked on @BBCNewsnight about the chances of this happening, replied “zero”.

(BBC Newsnight, 18th April 2023).

He should know, being the Co-founder of Amadeus Capital Partners, and writing a book on technology sovereignty.

He said Government efforts to reverse Nexperia’s takeover of Newport Wafer Fab would achieve exactly the opposite of what is desired: technology independence. 2/
Semiconductor sovereignty will be achieved by China, US and EU. China has the money and talent so it is only a matter of time.

Whereas Britain “is a minnow and will always be a minnow”. BREXIT was the greatest loss of sovereignty since 1066.

The aims of the toolkit are:

- To be a companion, not a blueprint, for a community group
- Provide practices and tools that are practical and accessible
- Enable a community group to form, think through local situation and identify actions …
...
- Helps ensure a diversity of views  and approaches – technology, history, the arts, culture
- Recognises value in personal and community action and links this to wider systemic change ...
- The toolkit does not try replicate resources for specific project types, or to cover climate science

The toolkit is engaging and usable by any community group anywhere which wants to find its own voice.

The EPC tool produced by Elmhurst @consultancy_elm and others makes no provision for larger properties using cascade heat pumps for larger properties. In fact, it only allows for very basic system specn.(such Air to Water, Air to Air, etc.). @BRE_Group 1/
Contrasting with gas boilers, where it allows the surveyor to specify the precise model being used on the SAP database.

It results in ludicrously high bill estimates for larger properties, because they are still assuming you are only using one heat pump that can’t cope. 2/
Hence the energy demand can’t be met a single heat pump and the flawed 'algorithm' appears to assume that the rest is delivered by direct electricity at a SCOP of 1:1. Instead of the reality (bills coming down) it massively inflates the projected running costs. 3/

What are retrofit options for someone with 90-100m² ‘hard to treat’ home, concerned about rising gas prices and the planet? Installing a heat pump is single largest measure for lowering the carbon footprint, but how soon to fit one on retrofit journey? #retrofit #heatpumps 1/
Doing nothing on fabric or gas means bills will escalate
and there is a serious risk that such a home will have lower resale value in the future. By starting to think about retrofit, home owners might do things they have put off for years, like clearing the loft. /2
Getting off gas early prioritises planet, without bills needing to rise.
Install ASHP early alongside
Limited fabric measures, such as loft insulation to modern std; seals / brushes for doors / sash windows for drafts (and cavity wall insulation added if applicable) 3/

Soil carbon is important but it is staggering that both Minette Batters and Prince Charles have made unchallenged statements on @BBCr4today : That some farms are already carbon neutral and that soils could take up 70% of the world's emissions 1/
This is all in an effort to promote sustainable livestock farming. Like Graham Harvey in his book ‘Grass-Fed Nation’ they have been seduced by the claims of Allan Savory; but these have been thoroughly debunked by the Food Climate Research Network
oxfordmartin.ox.ac.uk/downloads/repo… 2/
The fallacy rests on a confusion between fast and slow carbon cycles, between carbon stocks and flows, which with a little bit of naive maths creates a myth that now permeates the NFU’s PR on the future of farming. We need better soil health to stop carbon release … 3/

@mskathleenquinn I have never made it there and maybe never will, but nuclear weapons changed my life in different way. In 1981, Professor Mike Pentz, who led the formation of the OU science department, founded Scientists Against Nuclear Arms (SANA). I was at Bristol Uni. doing a Post Doc. 1/
@mskathleenquinn I went to hear him speak. What an amazing speaker he was; I signed up on the spot. Within a months it seemed I was on the National Coordinating Committee. It kind of killed my passion for science, something I'd been in love with since a young boy. I left research 2/
@mskathleenquinn I went into the world of industry and in my spare time spent a lot of the 80s working in the background helping to develop tools for the anti-nuclear movement (like a Program to assess impact of nuclear attacks run on an Amstrad PCW 8256, given free to local authorities). 3/
