Your black hole of insurmountable naysayism is so in denial that it's fully understandable as to why you'd knowingly work on behalf of the likes of big energy, or GW Bush or for that matter Hitler. - Brad Guth -

In internal combustion engines, the fire goes on and off. I'm just wondering out loud what happens to the metal parts which will be rather hot when hit with LOX. Will thermal stress cracks be an issue? -- Jim Pennino Remove .spam.sux to reply.

The solar cells have more output when they're closer to the sun. Good idea. John

If the common vernacular fails, use equations. -- Jim Pennino Remove .spam.sux to reply.

And I had the opportunity to sell to a major cigarette manufacturer. Turned them both down. And I sold several thousand end-use load survey meters used to analyze power consumption and temperature data in homes and commercial buildings. We're engineers here; we do things. John |
