I'd like to answer the call for fresh blood. I've lurked on www.greenenergyinvestors.com since 2009, having been drawn to the site via HPC.co.uk. To me, the member discussion and book/podcast suggestions have been invaluable over the years, so I'd like to join in and try to contribute where possible.
I don't think I'm ever likely to be a prolific poster, but hopefully I can give back a little to the people who have helped and don't even know it!
As a starter for ten, I'd submit the last podcast I listened to: http://downloads.bbc.co.uk/podcasts/radio4/reith/rss.xml
This is the 2012 Reith lectures by Niall Ferguson, who takes on the rule of law, financial regulation and public institutions in his lectures. I think he's quite right in his analysis for the most part too!

Just to add that Dr Bubb announced me in the other thread as Jonnyfive, but on logging in I rediscovered my old account as bobman. I guess that makes me bobman forever more.
