[de] Weniger Strom = weniger Diesel beim #cccamp19! Ein paar Bemerkungen zu Elektrizität und Nachhaltigkeit. https://events.ccc.de/2019/07/26/use-more-bandwidth-and-less-diesel/ Für mehr Ideen zu einem nachhaltigen Camp, folgt uns bitte, wir werden bis zum Camp mehr dazu schreiben. Bitte teilt auch eure Ideen!
@c3sustainability Would it be possible to heat the shower water directly with diesel? (Better yet use the waste heat from the generators.)
As I understand the setup, currently we're generating electricity in diesel gensets (30% efficiency), and use electric heaters to heat water in the tanks.
That's convenient, but energetically probably the worst possible way.
Yeah its daft this energy isnt used
I was part of a coop working on (among many other things) offering electricity and heat from used cooking oil powered diesel gensets at events. They got a suitable genset after I left the coop, but think that they fuelled it with fresh rapeseed oil
Got lots of friends who work on rubbish/recycling at festivals. From a sustainability perspective most are terrible, even if you ignore all the transportation energy involved.
I think one issue here is making sure only heat (and not any carbon monoxide) finds its way to living areas plus most heaters using gasoil/diesel are made for large fixed installations - a bigger one is across Europe (other than CCC it seems) festival type events (even some which claim to be eco-friendly) are just viewed as short term hedonism rather than any genuine attempt to improve things >>
@vfrmedia @dazinism @ckeen @uint8_t @c3sustainability One thing to consider is… if the generators are liquid-cooled, using a heat exchanger in a combined heat and power setup (although I don’t know if anyone does portable generators set up for CHP).
That way, you’re getting heat from the generator’s waste heat instead of the generator’s electricity output, with no need to worry about exhaust gases from directly burning fuel for heat at the point of use…
One rave crew I worked with in the 2000s used a genset where the prime mover was the engine of an old VW Beetle, that had been converted to LPG. When it worked it was impressive but I remember it being quite temperamental (probably lack of maintenance, as the concept seemed sound enough).
Yes, I was thinking of CHP via heat exchangers fitted to liquid cooled engines Potentially an easy win for a load of energy, if you are doing a lot of heating anyway
My brother worked for a company that did renewable power for festivals- solar & biodiesel
They moved into building big battery banks with top notch inverter/chargers linked to diesel generators & selling to hire companies that serviced the construction industry
@vfrmedia @ckeen @uint8_t @c3sustainability
PS: I spent almost 25 years of my life as part of the UK's rave scene including helping organise a few events and being a steward at a couple of small festivals, and until I learned about CCCcamp I literally had not heard of any event in Europe that addressed sustainability/resourcing issues and doesn't also pass costs/burdens to the public sector in the region where it happens (I wonder if the relatively high ticket price is a reflection of this?)
@frainz they add a coloring agent to make tax evasion harder
