Big Green Gathering

Just back from the Big Green which was actually sunny – hooray! Very hot, in fact. Much indulgence in such activities as sitting on the grass, wearing dresses, going barefoot all day and eating ice cream, and about time too. I’d almost forgotten how hard it is to sleep in a tent in the sun though - more tent adaptations on the way…

Tried to stay away from all the gadget shops in case I ended up buying a solar powered twirly thing, which is the non-green alternative to doing without a twirly thing altogether.

Topping all the gadgets by quite a long way though was the cycle-powered washing machine, which I can’t believe I’ve never seen before. Bike wheels go round, washing machine drums go round, it’s obvious, isn’t it? The water wasn’t heated, so if I made my own I’d probably put the water tank on one side with a mini-rocket stove under it made out of veg oil cans, but it did the trick with the small load I used it for.

I also got my very own gadget made in the crafts field. Loads of the food stalls give you wooden forks, but they’re pretty horrible to eat with so I got myself a small metal one for 40p at one of the tat shops. I kept finding myself trying to cut up potato skins etc with the edge of the fork, so I got someone with a cycle-powered grinding wheel to grind the edge down into a blade for me and I now have the ultimate bit of camping cutlery.

Also inspired by things I saw there, the next wacky structure to appear on my allotment will probably be a geodesic dome. I had a good look at one that had been put together with cable ties, and talked to the guy who made it about which were the long and the short pieces, which of course I can’t now remember. The trick is to have an 11% difference in length between them, apparently. I think I’ll make a model out of construction straws first.

So many projects, so little time…

Hi Alice, I found your blog through a comment you made on the Climate Camp facebook group. Anyway, as a gas and heating engineer I found the ThermoFlow thing interesting. I have never heard of this. If it works, I think the efficiency improvements can only be minimal, as most boilers nowadays work at an efficiency of anything from the high 80's to about 93% efficiency. I was a bit concerned that this ThermoFlow is made from "rare earth Strontium Ceramic", whatever that is? Doesn't sound particularly green to me...? I was also very concerned that this device is apparently being used in the Devonport Dockyard. I live close to Devonport Dockyard, it is the base for the maintenance of the UK's Trident Nuclear Fleet!!!
No environmentalist worth their name would support making Britain's nuclear arsenal more efficient!!!

Peace
