Hey Smudge, are you psychic or what. A bloke in work, just this week gave me a Spanish 33cc engine and fitting kit for a pushbike. I have just fitted new main bearings and will try and fit it to the front wheel (a la velosolex) of my Schwinn cruiser in the next couple of weeks.

Lol, I just wish you didn't need to wear a motorcycle helmet with them  ::)

Does this mean sub 50cc engines and suits for the Dragon next year...  :D :D

And let's not forget that we don't just have to address to power production, the biggest chance of making a change in our consumption is to find ways of reducing the power we need.

A classic example is the low-energy light bulb. My house now demands, in total, something like 250watt for lighting. A few years ago that would have been the energy demand for two rooms.

Also, heating will never be cheap (as Beeman pointed out), so why waste it by having a poorly insulated home? Less loss means less input is required (unless, like Mrs Onepot, you think the surface of the sun is a bit chilly).

i was going to post, but you said pretty much what i would have said. im a heating engineer by trade, but it still amazes me that i look at houses where they will be prepared to spend a couple of grand on a heating upgrade, but not a couple of hundred on keeping all that expensive heat inside the place!!

there isnt a single solution to the energy debate, it has to be a large number of small solutions depending on local environment, im a big fan of hydro, but on smaller local scales, you dont get the transmission losses when the plant is in the back garden, i like the micro hydro at newmills in derbyshire, its in the remains of a victorian watr powered cotton mill, and uses an archimedes screw to generate power, it also works on very low water level differences and flows, theres only 6 foot or so difference between top and bottom of the unit. as well as this theres solar thermal, pv, wind tidal and wave as well as large scale offshore wind. the irony of all this in view of the developments in japan is that had the renewables industry had the same financial governmnet support and subsidy that the nuclear induistry has had this past 50 years, then we might not be needing to have this debate, and nuclear power plants could be mentioned in the same kind of 'what were we thinking' arguments as asbestos and thalidomide.

Asbestos is simply obsolete, we can make fibres with same properties and none of the risks of natural ones. Thalidomide is coming back as a treatment for leprosy and some cancers, it's just another drug that pregnant women should avoid. It's not the technology, it's how we use it. The asbestos legislation of the 1960's was based on the "Radium Girls" scandal of the 1920's. We haven't stopped using Radium where appropriate just because bad managers had their unaware staff carry the stuff in buckets. Likewise, the insane Windscale style aircooled reactors and Soviet "Piles" of the 1950's look insane to modern designers.

The Daily Mail would soon want those central heating systems banned anyway. I can see the headline now "Escape of Superheated Hydrogen Dioxide scares plumber".  :-\
