The protocol of greed: capitalism, machines and bitcoin.

My comment to the article “Bitcoin = Death Processors
First of all, we should separate “blockchain” as a general system of distributed ledger form Bitcoin, that is very specific implementation thereof.

The whole system will be based upon principles of solidarity economy, open technologies and cooperative movement. Continue reading The Octagon

panel-measurement-01102015It is my pleasure to inform that on Sunday, 27.09.2015, in Anexartiti Protovoulia in Thermaikos we have fully assembled and installed (inside the office big window) first prototype of a passive air heating solar panel, developed by Morris Dovey, who was here in August to teach us how to build it. The panel is working very well despite the fact that it doesn’t exactly follow the design specification at http://www.iedu.com/Solar/Panels/index.html. I will probably provide temperature measurements (outside, inside-input, inside-output), as soon as I put my hand on 2-3 thermometers.
