where has all that time gone?

[temmujin] 25/5/2014 19:09

so who does errol flynn post under now? travis? or captcash

good luck with that one maestro. does it run on carrot juice like the last?

[temmujin] 07/4/2014 19:10

rocket..i sold it last summer for £150 but got another one off ebay for £500 minus the qxl stickers...i call myself e-baycourier now

[rocket fuel] 07/4/2014 19:09

ron lol you didn't listen maestro. we all told you at the time. you were like a magnet to every insolvent mug punter sub penny stock!

[temmujin] 07/4/2014 19:08

i'd like to know what happened to all my ronson shares? Nicos put them in a safeguard investor account..found out his sons got done for fraud so was he in with the ronson scam?

[rocket fuel] 07/4/2014 19:06

hoodless brennan lol warned you about those pirates many years ago maestro. how's the maestrovan.. are you still kipping in the back of it? bet you still got those qxl stickers on the back window lol

[temmujin] 07/4/2014 19:05

yeah rocket, popeye warned me about hoodless..should have took heed

[temmujin] 07/4/2014 18:59

remember stewjames and errol?

[freddie ferret] 16/12/2013 15:59

Very windy at the moment!

[temmujin] 25/8/2013 21:40

wish i could turn back time

[temmujin] 08/7/2013 23:04

those were the days..if only

Thanks Freddie- thats what I was after. :-(

If my memory serves me right the maximum you can suck water up a tube is 32 feet minus the vapour pressure, by bernuolli effect or any other effect. Think about a mercury barometer the height of the column of mercury, and that mercury has a density of 13.3g/cm3.

Continuous tension in a cable will not enable you to extract energy, force x distance, however if the tension in the cable varies piezo electric effects might be worth exploring, though the energy transfer efficiency is poor for these.

Hi Freddie,

Yes, I have also built windmills before using thin arms between the hub and the blade in order to achieve a greater spun area for a given blade length. But you cannot compete with the area swept by a large wing attached by cables. The tension created by the lift as it sweeps accross the sky is such that it must be harnessed securely to the ground using very strong cable. I had 2 thoughts: The first you know. Somehow transfer the energy in the wire tension to electrical work/ potential. The other really off the wall idea I had considered was to use some kind of hollow cable to connect to the top edge of the wing and use the bernuolli effect to suck liquids up from a lake or sea and out of the top to rain back down. The flow of liquid could then certainly move an impeller down at ground level and if the wing was high enough, the effect would be quite spectacular to say the least.

Interesting to consider how high a kite could go.

If it could get high enough then windmills in a jet stream could be interesting.

Cheers Freddy. Well there is always so much loss involved in conversion and storage that you could argue the care for a direct power source for any practical application ie the sun is great for boiling water. I'm just interested in the way wires behave under tension I guess- there's no need for great power here- just for a pcb/ LCD arrangement.
