Click below to download a PDF based on my presentation to the Humanist Society of Victoria on 23 August 2018. It started as a presentation, but I’ve added a large number of slides since then – far too many for a single presentation (but good to help explore related ideas that you might find interesting). There are two file sizes for the same presentation content – one has clearer images (and it’s better – if you don’t mind the large file size).


Very clear images, 66 MB file size:
Sustainable energy – fresh perspectives_v.0.94 – hi-def


Low quality images, 13 MB file size:
