DaveH Posted May 22, 2012 Share Posted May 22, 2012 The big scanner is powered from an external water wheel, so its a good job the drought has been cancelled. Upgrade it, If the external water wheel is an undershot wheel replace it with an overshot wheel. Gives more power output from the same volume of water per second passing over the wheel. Let's bring that water wheel technology right up to date and move into the 19th century! lol Link to comment Share on other sites More sharing options...
RichardB Posted May 22, 2012 Share Posted May 22, 2012 With your effort it's done a damned good job for a total outlay of bugger all - now even a team of transcribing Monks at Lindisfarne hundreds of years ago would have cost more than that (medieval to decimal conversion included). Having gone a few map scans I always found it was me that was the slowest element in the process. My fleet of scanners are still as slow as ever he he Link to comment Share on other sites More sharing options...

Never knew you had a water wheel on your house, or even a river and reservoir nearby to power it. Would have been handy in the early 1970's to cover those 4 hour power cuts Link to comment Share on other sites More sharing options...
Stuart0742 Posted May 23, 2012 Author Share Posted May 23, 2012 Never knew you had a water wheel on your house, or even a river and reservoir nearby to power it. Powered by by a hosepipe, then all the water go back down the drain and back to Yorkshire Water and they can then sell it again, see no waste and very environmentally friendly.

Only works in times of no drought and hence no hosepipe ban. Rubbish if your water is metered rather than rated Link to comment Share on other sites More sharing options...
DaveH Posted May 24, 2012 Share Posted May 24, 2012 But he would have been in a panic in 1976! Well, if we ignore the 2nd law of thermodynamics (the one about entropy and perpetual motion machines not working), he could use the energy produced from the water wheel to pump the water which had just powered it back up into the reservoir and use it again, - very economical on water in a drought Unfortunately it doesn't work, - and that's a physical law!

Rubbish if your water is metered rather than rated At times of drought I have an electric motor to power the waterwheel, which generates Electricity which powers the electric motor etc etc. he he Link to comment Share on other sites More sharing options...

History dude Posted October 16, 2012 Share Posted October 16, 2012 I have just found out recently that my broadband supplier was overcharging me. It turns out that I could have been paying half price and got a 10GB download limit instead of just 5GB They never said anything, just kept us on the old rate! So check that you are getting the best rate, won't mention the name, but just to say they advertise on telly using a well known comedian and a brass band ;-) Link to comment Share on other sites More sharing options...

So check that you are getting the best rate, won't mention the name, but just to say they advertise on telly using a well known comedian and a brass band Paying double the price for half the speed is paying 4 times too much in my book. My current ISP advertises on TV using a lookalike athlete, star of the recent Olympics, claiming that their broadband speed is the fastest like this well known athlete. That's got to be a lie. The athlete has been described, incorrectly, as "the fastest man alive". The real fastest men alive are the 3 crew members of the Apollo 10 mission (the one that flew to the moon on went down to low altitude to test out all the systems but, frustratingly for the crew, didn't land, - that was for the subsequent mission, Apollo 11) However Apollo 10 flew out to the moon when it was at apogee (its greatest distance from the Earth in its elliptical orbit). to do this it had to fly a little bit faster than the other missions and achieved 24.790 mph, the fastest speed ever achieved by a manned vehicle. Now I would prefer my broadband speed to be Apollo 10 speed rather than track athletic speed! ;-) Link to comment Share on other sites More sharing options...
