Have you ever tried powering a light-bulb using a cycle powered generator? Last Wednesday I went to screening of the film “Chasing Ice” organised by take one action<\/a> in which we were to power the entire presentation by cycling. I’ve had a go at cycled bulb lighting before and its hard work. Getting an incandescent bulb to light up anything like fully is a challenge even Wiggo wouldn’t relish. Compact fluorescent bulbs are easier but still take great effort. When I last tried it LED’s weren’t on offer, but these must be fairly easy since thay use 20% or less of the electricity of an incandescent bulb. So when I turned up for the outdoor screening at Edinburgh’s Botanic gardens I was expecting a small army of pedal power and spend the entire time pedalling. In actual fact the entire screening could be powered by 7 cyclists, 5 for the visuals and 2 for the sound (see pictures below).\u00a0 These powered a smallish screen back projected by an overheard projector and a reasonable sound system all linked to a laptop with the film on.<\/p>\n

I had a go at pedalling for about 15 minutes at the beginning, but there was a small but constant queue of eager volunteers wanting a go.\u00a0 Lucky I’d bought some warm clothes, for if you have heard of smellavision, this was freezeavision.\u00a0 Whilst the film showed ice melting we sat there freezing.\u00a0 Unfortunately the technology let us down.\u00a0 Heavy rain at the previous nights showing had damaged the equipment on the visual side and something went wrong with the sound side connection.\u00a0 It meant that in practical terms we powered about a quarter of the evenings sound and three quarters of its vision.<\/p>\n

As an experience it was interesting and the film was very good if depressing (but that is the subject of a future post).\u00a0 There are, however, some lessons here for our use of energy.\u00a0 The first is that its surprising what 7 cyclists can power.\u00a0 Technology has improved and electronics is getting more and more energy efficient.\u00a0 That’s the good news.\u00a0 The bad news is that we have more and more stuff and this overwhelms the efficiency gains.\u00a0 Our house is typical with often 4 out of 5 of us on computers.\u00a0 This makes us socially isolated and increases our energy use.\u00a0 To be fair the children are often doing homework and we have not reached the level of the mother who wrote an article in the Guardian Family supplement who banned all electronics for some months after she started telling her children dinner was ready by posting the news on FaceBook!\u00a0 We do sometimes sit down and all play a game together.\u00a0 In addition I’m trying to make sure I take time to read a book or play my guitar.<\/p>\n
