  1. If your trying to avoid toxic chemicals in all parts of the reaction... you could always use electrolysis of something like [ce]MgSO4[/ce]

     

    the problem using that is that it forms a coating of magnesium hydroxide and this slows down the reaction to a near stop quite quickly.

    I`ll also point out for the record that using carbon electrodes in H2SO4 although it works nicely for H2, you can forget about using the O2.

  2. HUH???

    (a(i)I'm not going to try to filter hydrogen made from a process involving harmful chemicals,(a(ii) I don't want to take any chances of leaving any kind of harmful impurities in the gas. I will only use methods of production that leave nothing toxic in the gas. There was another suggestion in one of my other threads to use (b)magnesium and water to make hydrogen, but this process produces a lot of blinding light, and I don't want to risk damaging my eyes. Does anybody know of a good method of eye protection when dealing with bright lights possibly containing high quantities of UV?

     

    (a)i) why?

    (a)ii) and NOT filtering will achieve this????

     

    (b) who on earth told you that load of garbage???

  3. there Are those that are too stupid to see past their Bigotry and asses others with Broad generalisations, this would indeed be indicative of a lower IQ, they tend to be Very vocal about it too and bring it up at every given opportunity.

     

    of course that doesn`t happen here, we`re all smart ;)

    aren`t we?

  4. Scientists, especially physists tend to think themselves open minded.

    Up until the moment you ask them about God, or UFO:s. At which point they become all closed and scary eyed and so on.

     

    I think this is because scientist in general do not want to think that there could be, in the universe, anything smarter than they themselves are!

     

    Which is not very open minded.

     

    Or clever.

     

    it`s foolish comments such as these that give us Theists a bad name! happily this IS a Science forum, and not everyone here tars us all with the same brush, as a Christian myself and Also a Scientist (if I must use that term) I`m well met by most here and respected as such.

    your brand of nonsense is nothing but Truly transparent to the collective intelligence here.

    IOW, you`ve wasted your time And a valid User account.

  5. it`s hard to say without actually being there and seeing it, but in `General` does it say the device is enabled?

    it might be an idea to see what driver it has as well.

     

    failing that, you`ll have to see if the BIOS picks it up, Does it have any s/ware on there, or is a blank new HDD?

    are the PIP settings on the drive correct also? if in Doubt leave them out ;)

  6. in device manager disk drives, have you double clicked on the drive?

    it should open a new window with details about it.

    the top tabs should read something like: General, Policies, Volumes, Driver, and Details.

  7. a lower ISO film will give better detail and less grain, but will require a longer exposure, so you`ll need some way of compensating for the movement or make a compromise between grain and speed.

    happily todays film grades are quite good! so anything up to 400ISO will be fine.

    the lower the F number the better too, sadly most lens arrays of a long focal length with a low F number are Very expensive.

    using a telescope however, I`m not sure how that would work out?

    I`v never interfaced a cam to to one before, but plan on doing so later on in the year with a webcam/laptop/telescope USB setup, the few experiments of tried this year (not published) show promising results ;)
