Read an article about this guy building a jetpack at $100K for public. Really inspired by his effort and perseverance. If only I have half his time and talent...
Then again about the story of sending stuff to space using balloon and rocket at really low cost. Why didn't the big guys think about this possibility instead of wasting millions of dollars, correction billions of dollars or "high tech" expensive space gears.
I have been very interested in space adventure, although not any where near a pro, I try to understand. To my understanding, apparently explosive works because of the ultimate number of molecules the reaction causes. Since each molecule occupy a certain amount of space, when a sudden expansion of it will cause explosion.
Consider car petrol, the chemical reaction cher out more molecules then it originally has in petrol.
Will TNT be able to power a rocket in that manner?
