.David MacKay FRS gave a brilliant talk today which was followed by Gallager code cake.


As usual, turn to David MacKay FRS for answers: withouthotair.com/c26/page_192.s… Nigel Bennett Andrew Neil

.REScoop.eu 🦋 Follow us on Bluesky @rescoop.eu yes, except look carefully at all numbers! Real solar parks have much LOWER panel density than I assumed. So UKpower/A is 5W/m2

.Gerrit Jan Schaeffer REScoop.eu 🦋 Follow us on Bluesky @rescoop.eu great, please send link 2data. Yes my RSsolar.pdf paper shows variation w location. 10W/m2 is typical in sunny locs

.@[email protected] Arthur Yip read SEWTHA chapter about fluctuations and storage etc?

.Arthur Yip @[email protected] gagan sidhu I disagree. Good to plan ahead and build cost optimal mix. Don't rush into cheap intermittents

.Arthur Yip @[email protected] see erpuk report on whole system cost. Optimal amount of intermittent wind is small even if their lcoe "cheap".


Richard Black Thor ⚛4🕊 @[email protected] David MacKay FRS Arthur Yip ERPUK report "Managing Flexibility..." online erpuk.org/project/managi…

Want to cut CO2? "The most cost-effective way to do it is carbon pricing. Period," says Ecofiscal Commission's @ctsragan globalnews.ca/news/2621461/e…

.Dick Winchester 🏴 Carbon Tax Center no, even better also have a green tax shift, where taxes are decreased on good things such as employment

.Arthur Yip Yes. But that sounds suboptimal in cost, compared with building the low carbon system that works December + all year. Erpuk!

.@[email protected] Yes, build a bit of wind in today's ff context & it reduces emissions. But if you want ZERO emissions system at best cost...

.Prof. Jean-Pascal van Ypersele (@bsky.social) thanks, I'm still perky! My "last blog post" may turn out like Douglas Adams's "increasingly inaccurately named trilogy"
