Re: Hydrogen gasoline equivelancey

<t>The problem with hydrogen is its thermal density, not its efficiency. <br/> Hydrogen is by far the more efficient burning fuel. More importantly, it <br/> burns "cleaner" producing mostly water with some side train reactions <br/> producing oxides of nitrogen whenever H2 is burned using ordinary ...

Re: Nuclear Batteries

<t>Adam,<br/> <br/> Don't even inquire about Pu-238 unless you want the federalis <br/> tapping your phone and hanging around your house. I wasn't aiming a <br/> criticism at you are anyone else participating on these boards. <br/> <br/> The problem I have are with the science community at large. Ba...

Re: Nuclear Batteries

<t>Quite honestly, I don't see any reason not to shoot for the entire ball <br/> of wax. Alpha and beta are both moving charged particles and there <br/> should be a way to arrange P-N junctions to convert that energy <br/> directly into electrical current. X-ray and gamma are both strongly <br/> io...

Re: Nuclear Batteries

So, use something lik lead titanate to make your P-N Junctions and
take advantage of the hotter isotopes. In a really big battery, there's
no reason you couldn't take advantage of some of the x-ray and
gamma radiation after a bit of research.

Re: Gobbledy-Goop - It's word soup

<t>It's beginning to sound like a round of inter-service rivalry to me. One <br/> of those goold old "Navy v.s. Air Force" squabbles. Mix that up with <br/> NASA's penchant for pushing engineering limits and you get <br/> something like this.<br/> <br/> I've dug around on NASA's web sites several ti...

Re: Gobbledy-Goop - It's word soup

Larry, you have got to be kidding me. Is that really the reason?

Re: Gobbledy-Goop - It's word soup

<t>Okay, I've been trying to dig up an answer to this question by going <br/> through the stuff on NASA's site. After many hours of searching, I'm <br/> still not clear on the problem. <br/> <br/> For a small system, the Brayton cycle design doesn't strike me as <br/> such a horror. It's when they s...

Re: Gobbledy-Goop - It's word soup

Is the reason we are limited to a design based on the Brayton cycle
because we haven't figured out how to deal with NPSH problems in
freefall--excuse me--microgravity?

Re: Regarding spinning hemispheres.

<t>Dave,<br/> <br/> Metal fabrication scares me not at all. It's the electrical stuff that <br/> worries me. It's a matter of experience, I suppose.
