Project Up - Hot Air Balloon





Introduction: Project Up - Hot Air Balloon

This is a very simple 972 cubic foot tethered hot air balloon that is capable of carrying a payload of up to ten pounds.

    I want to know how much weight this balloon can tolerate...????

    I had an idea using this design, could someone tell me if it's plausible? I'd make the balloon/burners, though instead of tying a camera i'd secure a harness, get in said harness, though instead of flying I'd use it as a sort of low-gravity simulator, would the balloon be capable of lifting a person 4-5 feet in the air, then drifting slowly to the ground, if not, what would I have to do to make it able?

    You could shoot for a Mars equivalent gravity at 38% Earth's, which would make your balloon a bit smaller, and would probably be a bit safer. So all you have to do is multiply your weight by 0.38 then divide the result by the current balloons lift (approximately 15 lbs) and then enlarge the volume of the design by the resulting factor, this should get you somewhere in the ballpark, but ambient temperature, density and altitude will have to be compensated for as well.

    Sorry Jim, but this design isn't going to cut it. At max it provides 15 lbs, of lift, which (I think) would like losing 15lbs while keeping your current strength. If you were looking for something to simulate the gravitational pull on the Moon (1/6 of Earth's pull) you would need something that provides lift equal to 5/6s of your weight, Unless you weigh 18 lbs, this size of balloon won't work.

    Would it be possible to use something else other then a seal-a-meal to make the seams? I thought this was a really cool project. I plan on building one except I don't have a seal-a-meal.

    You could try an electrified wire loop heating element covered with an asbestos like sleeve but if I were you, I'd go check out Good Will or some other junk store for a used one, I'm sure they'll probably have it, or something else that's close. I love junk stores!

    Perhaps its worth attaching an "if found" note to the payload?

    In hindsight...yep. But I thought I'd recover the 'payload' at the end of my line. I just didn't foresee it burning through like it did. oh well, I'll definitely include contact info at the beginning of the video and on a tag attached to the video device the next time around, just to be sure.

    Found it! (heh)
