High temperature solar … sand bricks.

This started with a fascination with Markus Keyser’s solar sinter. After unsuccessfully trying to get a Fresnel lens cheaply, I gave up on this idea. It also just didn’t seem that easy to do; too much fiddling for a hobbyist. When I sniffed around his website some more, I got the feeling he felt the same way. Compare his more recent 3D glass printing which I think could be done by melting the sand with a solar thermal collector (more on this below), and then interestingly, when I found his thesis defence, his wider logic was particularly impressive.

Science entertainment in Hopefield

‘Adventure Sport and Science Tourism’ was a point on my very first business card. I think I had something like the Cape Town Science Centre in Observatory in mind, coupled with orienteering and adventure racing. Now I am thinking to have a ‘Science Barn’ where one can have Virtual or Augmented Reality events, and, you know, entertaining events that educate in the fields of STEM, with the Social Science angle ala STEMS2 . My problem is that although I can rationally assert that these are all very important, I get bored with these. They are not fun or extreme enough and actually, I don’t need to conform to a curriculum or whatnot. I also don’t want to invest in things that stand there gathering dust. Better to invest in things I’d use, but that can also be opened up to the public. So this post is a reminder of the stuff I’ve come across that I’d like to try out, and maybe it can generate excitement and income on the side.

Sludge to resource workshop feedback

The past two weeks have been busy in the best way, but it means I’m behind on writing how it all fits together.

I attended a Sludge to Resource workshop in Durban, 23 – 24 October 2018. My write-up is available here (word doc) and I hope to pull some highlights into the post itself in due course. Some info, with some schedule changes: http://wisa.org.za/event/sludge-to-resource-symposium/

Moola for Amanzi

Please note: I’m busy moving blogs, and copied this content over. The image links are going to break, if they haven’t already. It is what it is.

The report below is adapted from the WaterNetwork website. Merah Mas founder, Bernelle Verster was the main organiser of this initiative. The competition, which was part of a bigger initiative – the Dutch-SA water partnership – aimed to generate high quality investment proposals addressing water and sanitation issues and build awareness in the public eye, the water sector and sectors outside conventional water-related industries, so that business can go hand in hand with access to clean and affordable water.
