    Boston, Possibly as fertiliser as full of ******** but toxic by-products may cause unexplained collateral damage, just bury them in bio-mas land-fill and leave for a million years?

    I do not worry too much about the "super-storms" - - - except for the economic ones that can strike anywhere without much warning:!:

    only way to really know is to dry one out
    grind em up and give it a try
    I say they burn just fine
    might work to power the big steam launch
    and it seem only reasonable to have an alternative fuel source in a pinch

    I wonder if I could patent this
    dried and ground politicians
    40 lb bags
    contains x number of BTU
    suitable for home use

    I'm going to make millions

    I think the application was to convert it into edible protein called Soylent Green - The movie is probably copyright too, and fiercely defended by a team of lawyers... which reminds me of another matter, sent via PM :D:D:D

    That Waterworld trimaran is too small for my requirements.

    Leo, - A nice bit of lateral thought....

    Thanks, but that one is not all my idea. My colleague Brain Kirke is investigating the feasibility of the system, but it's hard to get a small grant to buy an oil tanker!

    I've been trying to find useful things to do with energy harvested at sea. My first thoughts were hydrogen and fresh water for ships so that they don't have to lug fuel and water for an entire journey.

    Another interesting idea Brian came up with was to use wave energy to pull nutrient rich water from depth up to the surface. Natural upwellings can support huge fish stocks so it's not completely nutty.

    All the best,
    Leo.

    Hi Leo,
    Thanks for responding... How effective are those ring-drive-turbines? - I thought they were just an effect for the 'Water World' movie... I have seen some other shaped blades forming a sort of spiral that do not need steering to develop power from the wind, but assumed all lacked efficiency at some level else they would be used more often...

    My apologies for hijacking this thread.

    The "ring-drive" is just an alternative to a heavy gearbox. Wind turbines are fast reaching their practical size limit. 5-10MW is about the limit for the propeller type of windmill because the gearboxes are very large and have to be located at the top of a strong tower. Helicopters have to transport maintenance crews to the top of these towers and that's a dangerous business offshore.

    The vertical axis turbines in the image are called Darrieus turbines and the curved shape of the blades is called a Troposkien. It's basically the shape that a skipping rope would take when you rotate it between fixed points at the top and bottom. There are also straight blade variants of the turbines; the egg-beaters on the ship are just one embodiment of the idea.

    The main problem with these turbines is the enormous bending stresses on the blades. The Troposkien shapes minimise those forces but are more difficult to fabricate.

    Vertical axis turbines are aerodynamically more efficient than propeller types because they get two bites at the wind. They can extract energy on the upwind side, and then a smaller amount from the downwind side. Against this better effiiciency is the fact that they require a lot more material than the elegant thin blades of horizontal axis machines. So, no, they aren't just a sci-fi effect created for Waterworld.

    I'm interested in producing more than just electricity. Prop-type turbines are very efficient at that, but vertical axis turbines might (I stress, might!) be more appropriate for some other applications such as pumping water etc.

    It's all good useful fun!
    Leo.

    The turbines on the ship in the image I posted earlier are really just a way of whipping chocolate in the hold into mousse. We just say it's for desalination to increase our chances of getting grants.

    "Prove" that it would inhibit further development and with enough vessels equipped reverse the trend by mixing the air and sucking nutrients from the depths so save the world from a food shortage (don't say how many is enough, just that more are required to reverse this very strong trend which has increased in intensity/strength), - and when you succeed, claim to have done the job that was probably unnecessary anyway as global warming trend has turned as is expected but obviously neither side are aware of this....

    A chocolate boat is not so silly. I once use rice for filling out some filler for stuffing in the bottom of a dinghy. As people were walking past one guy had to ask did'nt he?

    He said why are you using rice, I said because if I get ship wrecked I can eat the boat!!

    Ask a stupid question and you get a stupid answer.

    Strangely he walked away happy with that explanation.

    What would we do if there were no dopey people to stir:?: (probably be even more bored shitless?)
