Hot Air

Your programme often suggests that certain actions should be implemented after an item has been discussed. Does anybody take notes of these and other suggestions in order to hopefully get words put into actions? As with Question Time-style debates, I am often left with the feeling that any constructive ideas are left to vanish into thin air instead of followed up and turned into reality.
Starting a Recycling Business

I've just spent two hours ploughing through useless information on the internet trying to find information on recycling. I want to create a business which recycles the waste produced by wood-working industries around where I live. I own a 25 acre site and have spent the last 20 years successfully running my own company and now I want to put something back to help our planet. Where can I get advice and support for such a venture?

Liming and Limestone Quarrying
We're moving to an area near the Margaret River to produce wine and olives. Liming the soil is standard practice there because of the very acid soils. Is the practice of quarrying and crushing limestone to apply to farmland sustainable?

The Pedalling Powerhouse

An athlete from Birmingham asked whether or not his group of friends could power their own house using tread mills or bikes on rollers. These are Philip Stott's calculations:

  • Ever optimistic, assume a small, highly-efficient, ecohouse requiring our cyclist to produce, on a sunny day, about 2 usable kilowatt hours (kWh) of energy (remember energy is measured in kilowatt hours).
  • A reasonable cyclist can produce about 260 W (watts) of peak power, although the figure for more continuous cycling is likely to fall to around 150 watts, and this is probably only truly sustainable for some 30 minutes. You therefore would need between 8 to 14 cyclists pedalling furiously for one hour to get anywhere near sustaining even the tiny demands of our ecofriendly house.
  • A top racing cyclist, a Superpedaller, by contrast, with around 150 rpm at crank, could just about produce, in old fashioned terms, 0.6 HP (horsepower), or some 440 watts of peak power. In this case, you would want around 5 Tour de France-level cyclists peddling in line with effortless ease for an hour or so, although this does not really allow for friction, energy efficiency loss, or sheer exhaustion!
  • And for the Pooh Bears of this world, not to mention real houses - well, 70 hours a day might just about do it, if not eclipsed by death! And you have to crack the problem of battery charging. Nevertheless, a nice idea to peddle.
