Printer On Fire

I’ve been developing two ideas in my head lately.

First idea: hydroxy power boots.

Wear a pack on your back with a water tank and a battery, and tubes and wires going to your boots. The battery electrolizes the water (which is also used for cooling), powers the cooling pump, and fires the spark (plug? wire?). The hydrogen-oxygen gas is sent to the boots via a tube, into long cylinders.

I’m still trying to figure out how to get the stuff through the tubes, proper spark timings, and boot articulation so it’s not clumsy. I’m also trying to figure out the force the combustion would provide.

Idea two: magnetic catapult trains.

Think maglev trains, but made out of some sort of magnet-shielding material (mu-metal?). They’d go through giant Gauss guns to accelerate them to very high speeds.

Possible problems: erasing any magnetic media in the train. I’m also trying to figure out whether the people inside would be able to survive the accleration (whether in acceleration couches or not).

Hmm.
