In a paper from last August they outlined how it would work (PDF), and now they know it does. Space.com also has more information on the paper and how nano-scale aluminum functions as a fuel."

Hmm. One _could_ make solid fuel with rice flour and potassium chlorate or a similar oxidizer...

A better article on the engine here [inventube.com].
However I don't get how TFA considers this fuel as "environmentally friendly". Firstly one of the byproducts is aluminum hydroxide which, apart from helping us with our stomach ulcers, may be linked to brain disease - but I don't really care about that - the amount generated from a few rocket launches won't kill us all. But I argue that aluminum is not a naturally occurring substance - it has to be manufactured, and aluminum manufacture is the most energy intensive process around. So don't come to me with "environmentally friendly rocket fuel" when god knows how many tonnes of CO2 were dumped in the atmosphere to make the energy to refine that bauxite.
Still, if it works, it's better than "other" fuels that have extreme storage or environmental implications. Good for them.
