Spent a couple of hours at the Eco Show at the Brighton Centre yesterday (the Landlords Show was on as well, so popped in there too afterwards).
I am looking at getting a small holding, off grid, in a few years so am keen to see what self-reliant renewable tech is available. I am also keen to see what bogus stuff is being touted too!
The best single product has to be the civilised composting toilet - it was there last year, and seems to have been on the up since then - with an even smarter stand this year. Waterless and with a solar powered fan, a completely isolated device for your 'convenience'. In fact they do a toilet cabin (complete with shed) that can be dropped off complete, put anywhere, for around £1000. http://www.eco-toilets.co.uk/blog/
Sussex Uni had a display - a product that caught my eye was a reservoir that catches the first cold water from your shower before the hot comes through (rather than letting it run straight down the plughole), and then feeds it back into the flow when the water is hot. A saving of 10pints of water per shower would mean an annual saving on a water bill of over £100 for a family of four. No power required, all done passively!
Rainwater reclaiming was interesting to - for the garden/car etc and can be used for flushing toilets. They all now seem to have mains 'top up' feeds, so no need for two pipes to everything - which is neat. We may well put a big flat vertically mounted tank on the back of our garage...
Saving the best service till last...
The Green council have savaged our public transport to help their pet Coach company get a bus route, and have thrown millions at cycle lanes which help a few central Brighton cyclists but inconvenience all Brighton motorists... This means my wife and I have to give regular giving regular lifts to our lads, either to a better served bus stop (loads of short, inefficient trips) or all the way to/from college/work.
But at the show we discovered 'Wheels to Work'/'Wheels to Collage' http://www.eastsussexwheels2work.co.uk - who rent fully serviced/insured etc electric bikes and motorbikes to victims of the Greens, like ourselves. Just need to check the cover the city, not just the county(!).
