Fuel of the week: Titanium

Titanium is an interesting fuel for a couple of reasons. Firstly, it’s a pretty popular aerospace metal, so there is a fair bit of it floating up in Earth orbit ready for recycling. Secondly, as far as the base Neumann Drive goes, it is a well-behaved light refractory metal that does what it should. Thirdly, […]

Fuel of the Week: Carbon

As most of you know by now, the Neumann Drive was primarily invented by an Australian physics PhD student, Patrick Neumann. The question therefore came up on the interwebs, with particular props to fatblonde and WittyOriginalName of Reddit, as to whether it can run on Vegemite and/or beer. One of the great things about the […]

Fuel of the week: Vanadium

The Neumann Drive uses solid fuel and electricity to produce thrust. Over the next few weeks, we’ll give you a taste of how different kinds of solid fuel fared in our lab tests. The thing we’re trying our hardest to optimise is specific impulse which is measured in seconds. We measure how much specific impulse […]
