| said by haggleza  :I'm not sure if there are any legal obstacles, but has anybody tried using hydrogen as the lifting gas instead of helium. Some weather balloons use hydrogen. Hydrogen has a higher lifting factor and costs less than half of what helium costs. As these balloons don’t carry people the safety aspect is not so critical. Somebody still has to fill the balloon, and that is time when you are most likely to have a problem with oxygen mixing with it...As NASA puts it...an uncontrolled fragmentation could occur. Not to mention that hydrogen is a smaller molecule than helium, so it escapes even faster.
Not sure if you want to pay for all those windows that break the first time your floating hydrogen bomb explodes in a storm. :P
Hydrogen is cheaper, prosthetics are not. |
