To date, only 11 men in history have free-flown a rocketbelt (aka JetPack).

According to the Wikipedia article, at least one woman (Isabel Lozano) has flown one as well (happened almost a month ago).

As to why haven't more people flown the device, take a look at Isabel's pictures, and you'll see that had to make a custom cast of her body for the mounting hardware the device uses. Also, for some reason many people may not feel very comfortable with jets of gas at 740 C venting at supersonic velocities mere inches from their body.

We may be forced to do that anyway, if our peroxide situation doesn't resolve itself.

Have you looked into this guy? It looks like he has Peroxide concentrators ready to go. I think you bought one of his engines, didn't you?

It might not be a high volume, long-term solution, but it might at least get you flying again.

Well Tecnologia Aeroespacial Mexicana sells hydrogen peroxide distillation stills made entirely in borosilicate glass _image_ that merely removes the excess water. $5900 USD for a 20L unit.

They also sell a special catalyst _image _ made of Rhodium, Palladium, Platinum, Gold and Silver.

They also build rocket engines for satelites and jet packs. They also race jet cars and jet bikes. A link to some people that do this sort of thing....

Some info from the site... :
The hydrogen peroxide rocket engines are in fact steam rockets, but this steam is produced by a violent exothermic reaction of the peroxide. When passed through a catalyst pack, it decomposes into superheated steam and oxygen. This steam and oxygen at high pressure is expelled supersonically through a DeLaval nozzle, which produces thrust.
For each volume of liquid injected at the catalyst, after the reaction you get 600 times this volume expelled at the nozzle.

The most important part of these rockets are the catalyst pack, other elements of the system are a stainless steel pressure tank to hold the peroxide, a pressure tank to store nitrogen to pressurize the peroxide, a pressure regulator, a flow regulator, valves, lines and gauges.

The nitrogen is used to pressurize the peroxide tank and push the peroxide outside the tank. When a flow valve is opened the peroxide is injected into the injection plate of the rocket.
The catalyst is made of many silver screens that in the reaction converts the liquid hydrogen peroxide into very hot steam and oxygen at a high pressure, this jet of gas is used to impulse the vehicle.

This kind of rocket together with steam or a hot water rocket is the safest of all the rocket engines. This rocket does not produce flame and between the rocket is considered a cool rocket that doesn't need cooling and can be made of stainless steel.

The Hydrogen Peroxide is the same product used as antiseptic, but in space and rockets it is used at 80% to 98% strength, I use it at 90% and I produce my own peroxide.

The Hydrogen Peroxide is the only product used in the reaction, this places it in the monopropellant liquid rocket fuel classification.

The Hydrogen Peroxide contrary to many false information I read in the web, is a clear liquid, non volatile, non explosive, non inflammable and non toxic product that looks like water but with a great amount of oxygen, thats why in many languages its name is "oxygenated water", this product has a slight biting odor and a little bit irritating for the eyes, at the contact with the skin and the eyes it produces oxidation burns, so you must always wear rubber gloves and a face mask to cover your eyes.

This product increase its stability with concentration, yes!, the more pure and concentrated, the more stable!.
The 90% hydrogen peroxide must be stored in special 5254 aluminum alloy containers with vented caps in shaded or fresh rooms preferably, the product is safer to store than gasoline!, but you must store it in approved containers for hydrogen peroxide service.

The hydrogen peroxide is unstable only if it is contaminated and decomposes easily with almost any impurity, the heavy metals, some strong alkalis and the permanganates decompose it instantaneous liberating a great amount of energy in the form of very hot steam and oxygen.

At this strength the hydrogen peroxide is a very strong oxidizer and upon contact with organic mater it is burned, for instance if you soak a cotton rag with 90% hydrogen peroxide it burns very fast, also it can react in a hypergolic way if mixed with other chemicals.

Probably mail-order, too. :) Easy at The whole shebang

Probably mail-order, too. :) Easy at The whole shebang

Talk to these guys

The big deal about using hydrogen peroxide as fuel is the simplicity of the engine design. All you have to do is run the peroxide (which is, btw, far, far more concentrated than what you buy at the drugstore) over a platinum mesh, and there is a catalyzed reaction and the stuff goes off.

Combine that with a simple, pressurized fuel tank instead of turbopumps, and you have a rocket engine with the minimum of moving parts. Perfect for a technology demonstrator that's more about the other parts of the system than the rocket itself.

The late, lamented Beal Aerospace was building a big booster rocket by scaling up this technology, and with a fair degree of success. (Then NASA stomped them flat by announcing a "civilian space launch initiative" that would have amounted to subsidizing Beal's competitors. Beal closed up shop.) Read the Space Access Society's pages to see what they think of NASA these days.
