From Dr Gregor Czisch.
There are two subjects in Nigel Wakefield’s email I would like to address:
First Subject- Technical feasibility of complex multi-terminal HVDC systems:
Nigel Wakefield wrote

Can anyone elucidate on this?
Read MoreFrom the wonderful Electrical Review Column – Gossage “The late Professor Roland Levinsky was a pioneering immunologist, and vice-chancellor of the University of Plymouth. He died because, in atrocious weather conditions, he walked into a live 11,000 volt power cable left dangling across a footpath near Wembury, Devon. It was not as if the cable […]
Read MoreAccording to various news outlets today, Lord Truscott, one of the “Peers for Laws” had boasted that he had initiated amendments to legislation forcing the installation of smart meters. This may be a good thing I hear you say. But basically it is a wheeze to allow the electricity companies to sack their meter readers […]
Read MoreMore evidence that bio char is a good wheeze……… Abstract Abrupt Climate Change (ACC – NAS, 2001) is an issue that ‘haunts the climate change problem’ (IPCC, 2001) but has been neglected by policy makers up to now, maybe for want of practicable measures for effective response, save for risky geo-engineering.

FALCONER South Glamorgan, 12th January, 2009 The Editor Penarth Times Dear Sirs, I read with interest the letter from Paul Kinnersley in this week’s Penarth Times, where he states that the tidal lagoon is cheaper and more efficient than a Severn Barrage and he encourages ‘all […]
Read MoreWind generation is rapidly gaining a larger share of total renewable generation. In 2007, wind accounted for 32.7 percent of total net generation from non-hydroelectric renewable sources, as compared to 4.3 percent in 1997. The annual growth in solar thermal and photovoltaic generation has been sufficient for this renewable source to account, on average, for 0.5 percent of all non-hydroelectric renewable energy.
Read MoreChis Hodrien told us all at the October Claverton conference at Wessex Water Bath. that gasification-CCS was poised to become reality! It is interesting that the States are all legislating in favour of gasification IGCC (having recognised its many advantages for new-build), the very opposite of the British Gov’ts post-combustion CCS bias. They also recognise […]
Read MoreThe two announcements are the study on locations for future offshore energy developments, which identified scope for between 5,000 and 7,000 more offshore wind turbines, and the study on the Severn Barrage, which shortlisted 5 projects with the potential to supply up to 5% of UK’s electricity consumption. The conclusion of the UK Offshore […]
Read MoreThe above slide from Czisch (“An affordable renewable power system for Europe”) shows that Europe is unlikely to be vulnerable to sudden disconnection / sabotage of say a single or several, North African regions since there is considerable redundancy in connection and diversity of supply areas, and European grids of necessity already have existing sophisticated […]
