Boxing legend Floyd Mayweather Jr. is widely considered the greatest fighter to ever walk the planet. Last summer at 40 years of age, he won the easiest fight of his career getting his first knockout victory in over ten years versus former UFC champion Conor McGregor. According to reports Floyd took home more than $300 Million dollars after pay-per views were calculated and he’s been on a spending spree. Floyd first bought a $23 million dollar home in Beverly Hills, California, then an $11 Million dollar Miami mansion. But he didn’t stop there, he bought another $3 million dollar Bugatti, a $9 million dollar Siberian tiger and now a $4 million dollar jet pack and he did all this in cash. Check it out.

A jet pack, rocket belt or rocket pack is a device, usually worn on the back, which uses jets of gas (or in some cases liquid) to propel the wearer through the air. The concept emerged from science fiction in the 1960s and became popular as the technology became a reality. The most common use of the jet pack has been in extra-vehicular activities for astronauts. Despite decades of advancement in the technology, many obstacles remain in the way of use of the jetpack in the military or as a means of personal transport, including the challenges of Earth’s atmosphere, Earth’s gravity, low energy density of available fuels, and the human body not being naturally adapted to fly. To compensate for the limitations of the human body, the jet pack must accommodate for all factors of flight such as lift and stabilization.

A hydrogen peroxide-powered engine is based on the decomposition reaction of hydrogen peroxide. Nearly pure (90% in the Bell Rocket Belt) hydrogen peroxide is used. Pure hydrogen peroxide is relatively stable, but in contact with a catalyst (for example, silver) it decomposes into a mixture of superheated steam and oxygen in less than 1/10 millisecond, increasing in volume 5,000 times: 2 H2O2 → 2 H2O + O2. The reaction is exothermic, i.e., accompanied by the liberation of much heat (about 2,500 kJ/kg [5,800 BTU/lb]), forming in this case a steam-gas mixture at 740 °C [1,360 °F]. This hot gas is used exclusively as the reaction mass and is fed directly to one or more jet nozzles. The great disadvantage is the limited operating time. The jet of steam and oxygen can provide significant thrust from fairly lightweight rockets, but the jet has a relatively low exhaust velocity and hence a poor specific impulse. Currently, such rocket belts can only fly for about 30 seconds (because of the limited amount of fuel the user can carry unassisted).

A more conventional bipropellant could more than double the specific impulse. However, although the exhaust gases from the peroxide-based engine are very hot, they are still significantly cooler than those generated by alternative propellants. Using a peroxide-based propellant greatly reduces the risk of a fire/explosion which would cause severe injury to the operator. In contrast to, for example, turbojet engines which mainly expel atmospheric air to produce thrust, rocket packs are far simpler to build than devices using turbojets. The classical rocket pack construction of Wendell Moore can be made under workshop conditions, given good engineering training and a high level of tool-making craftsmanship. The main disadvantages of this type of rocket pack are.
