Domestic composting of Christmas tree?
Hi folks, Can I put my live Christmas tree onto my (small) domestic-sized compost bin? I would presume the main trunk will be too solid to compost down without being shredded first. But can I put the branches and needles in my compost bin? And is there any reason why I shouldn't burn the trunk in a ...

Here's the deal: PhotoVoltaic solar panels are expensive and inefficient. Evacuated tube solar hot water panels are pretty efficient and are capable of reaching very high temperatures. So - would it be possible to generate electricty by using evacuated tube solar hot water panels to boil water (or p...

I don't really get the aricon thing - not in the UK, anyway. Open a window. Wear cool clothing. Use sunblinds. Buy a fan. Sure, I take your point. And yes, I can survive without air conditioning. But my little home office here in muggy London gets really hot. I run a little film production / editin...

Hmmm... actually... this PDF describes (in far more technical detail than I can understand!) a 4.4kW solar cooling system. Here's a quote: Experiments with the half-effect system have been performed under several operating conditions. The maximum cooling capacity was 4.36 kW, 44% of the original des...

Eco-friendly air conditioning?
Hi folks, Loving this forum... loads of handy tips. It's hot here in London and it's due to get hotter this summer. Does anyone have any bright ideas about how to run air conditioning in the most energy-efficient way? Is the only option to put lots of (very expensive) PV cells on my roof and run &qu...

I went to the Ideal Home Show today. It was quite interesting but not hugely valuable. There was a worryingly small focus on the sort of things we're interested in on this forum. There was one stand for solar water heaters and two for spray-on insulating foam for lofts. There was also a small sectio...
