Hello everybody. I am just a man who interest in physics. And with the question I concern above is the reason I join this forum. Nice to meet you all
To the main point
I want to know exactly that, Is energy of one person enough to generate hot air for lift balloon system and himself?
By any means, with the main part from pedal and gear. Convert mechanical energy to heat the air into balloon. So we can fly with our energy created buoyancy force
I want to create such system. But first I need the possibility of theory. The calculation is too complicate, it need to calculate the volume of air a person can heat and leakage of heat to atmosphere
And the most important part is, which way is most efficient to convert mechanical energy into heating air?
I have design mostly electrical, pedal dynamo to nichrome coil and copper net plus Peltier heat pump(to cool air outside the balloon)
But there may be more efficient way, like fluid friction? or anything else?
I have approximate that human able to generate average 200 watt from pedal system
And overall gadget, bike skeleton and dynamo also the propeller and heat producer maybe 120 kg
But it more complicate to calculate the weight of envelop need to filled the hot air
So I need to lend you all wisdom
Thank you for any answer
