Does that have sentient killer food?
The sequel does.
Yeah, the sequel with the Clive Sinclair lookalike bad guy is what I was remembering.
Carrot-man on the original Lost In Space wanted to turn the Robinsons and Smith into vegetables but I don't know if they were in danger of being eaten.
he can just wait and buy a ticket on Blue Origin or Virgin Galactic and look out the window in the next few years.
Nah, he would probably claim that it's some kind of hoax.
Not sure if they still do it but in Russia you used to be able to go up in a two seater Mig 25, that thing can fly high enough...
That would be an awesome experience.
Fun fact. If you invested $1 in Amazon the day Branson announced Virgin Galactic, you'd have enough to buy a ticket.
Well maybe not quite, but it's been a long time that Virgin have spent not delivering
OK he's at it again
^^I see that he is now trying to distance himself from this being about proving a flat earth, i guess he has tapped out that source of income..........i wonder what made him change his mind.(2.8 million fund raising for next project, ching ching) lol
he wants to make a rockoon launch using a peroxide rocket motor. For someone that doesn't like science, he better find someone that does.
Rockoons are interesting though.
These guys seem to be quite active with those.
A peroxide rocket motor.........need i point out the irony. Lol
in theory they are a fairly low tech way to go, especially with a rockoon launch.
at altitude the tanks should self pressurize, so that removes some weight and complexity.
the high test peroxide passes through a catalyst screen, usually some silver compound and the ignition occurs. It's a simple monoprop solution
But the ISP is fairly low, the chemistry and engineering for the catalyst screens is not something he'll find many people with experience in, especially anyone who wants to ruin their career being associated with the nut.
It might be enough to reach the Karman line but not with a lot of margin. Armadillo Aerospace tried to use peroxide monoprop motors with jet vanes for directional control when they were in the X-Prize but they realized they would have to go with an oxidizer, and therefore the complexity went up. The flame was hotter, more force with the higher ISP therefore they had either have gimble for the motor, again the complexity, weight and cost went up. But it can be done.
Also large bulk amounts of HTP are not easy to acquire and are extremely reactive. I remember the Armadillo team spilled some on a leather shoe and it went into spontaneous combustion after a few minutes.
For a rockoon launch hes going to need an extremely big custom helium balloon, and be able to control it during the time he's allotted to launch without going past his NOTAM variance area, assuming the FAA would give this guy a license, and helium is extremely expensive in bulk too. I wouldn't bet money on any of this happening.
HTP rockets can work. I think they're really interesting which is probably why i am typing way too much. The UK launched their only domestically launched satellite using a peroxide rocket, The Black Arrow.
You gave me far too much credit, i was more along the lines of the perxide blonde, the archaic stereotype of being blond, and somewho who believes in a flat earth. Lol
This was the site:
Some nice youtube videos on the web.
I remember the photo of that. No visible exhaust--blasted thing looked like it had anti-gravity.
But of course, we all know mike is a fake because rockets don't work--right?
Didn't they use a peroxide based fuel for the ME-163? I only remember that it went KBOOM really easy and that it wasn't something you could handle without special suits..
I think it was hydrazine/methanol. Extremely nasty stuff. Parts of the frame were made of wood, and any spilled HTP would have essentially ignited the plane before it left the airstrip.
Indeed! really nasty.. the thing used these two, C is the fuel and T the oxidizer, both are extremely nasty..
^ Yep - powerful/energetic stuff but, very dangerous to work with.
But, when you're in a war..?
