	<htmltext>It looks like the exhaust products should include a fair amount of hydrogen gas. If so, you could add a liquid oxygen tank, inject LOX upstream of the nozzle and burn the hydrogen that's freed up to produce even more thrust, and more importantly, a higher specific impulse.

You might even be able to use it to create bimodal rockets that use the ALICE fuel for high thrust early in a launch and switch to pure H2/O2 later for the higher efficiency.</htmltext>

	<htmltext><p>C'mon, Slashdot, this is rocket science.  You shouldn't need help figuring this out on your own.</p><p>I'll come out and say it: this is a stupid rocket.  As Baldrson points out above, its "specific impulse" (the most important measure of a rocket fuel's usefulness) is less than a quarter that of rocket fuels currently in existence.</p><p>Aluminum is readily available on the moon, but not as big old bricks of elemental aluminum lying around.  You need to *make* it by <b>electrolyzing rock</b>.  (Don't panic, this is how we make aluminum on Earth today.)  The reaction is roughly Al2O3 -&gt; 2 Al + 1.5 O2, and oxygen is *always* a major byproduct.</p><p>Save that oxygen.  You get *much* more energy burning aluminum in oxygen than you do burning aluminum in water.    Estimated Isp for an aluminum-oxygen rocket is <a href="http://www.asi.org/adb/06/09/03/02/095/al-o-propellants.html" title="asi.org">285</a> [asi.org] -- waaay better than aluminum-ice.</p><p>Al-Ox rockets are nasty to think about, because the exhaust is a solid -- solid sandpaper, actually.  But the rocket from TFA has the same problem: Baldrson's data indicates exhaust that's 1/4 alumina, 3/4 hydrogen gas.</p><p>But if water is available, and you're gonna electrolyze something to make rocket fuel, why not electrolyze water to get hydrogen and oxygen?

<tokenext>C'mon , Slashdot , this is rocket science .
You should n't need help figuring this out on your own.I 'll come out and say it : this is a stupid rocket .
As Baldrson points out above , its " specific impulse " ( the most important measure of a rocket fuel 's usefulness ) is less than a quarter that of rocket fuels currently in existence.Aluminum is readily available on the moon , but not as big old bricks of elemental aluminum lying around .
You need to * make * it by electrolyzing rock .
( Do n't panic , this is how we make aluminum on Earth today .
) The reaction is roughly Al2O3 - &gt; 2 Al + 1.5 O2 , and oxygen is * always * a major byproduct.Save that oxygen .
You get * much * more energy burning aluminum in oxygen than you do burning aluminum in water .
