Roll on the 20th June

Graham your saying you have a vid of a magnet! Ball! anything! going round and round or up and over   I tried to find your ten year old vid  didn't see it Chet

I don't see it either Chet.  maybe rusty posted the wrong pages?  all I saw was vids from 2008, and just a mag rolling along the flat, or even a bit downhill.

ciao, dirt

A 747 carrying a shuttle won't make it to the 45km altitude needed to get the shuttle off the planet. The big tank will.
The two 'tanks' at the side are not tanks but rocket thrusters using up the fuel of the big main tank.
If there were a way to launch NASA shuttles more cheaply don't you think NASA would've come up with that in the first place?
Piggyback launches are, however, probably the wave of the future for other spaceflights, but those machines will be designed especially for that.

Those are not tanks on the side of the shuttle. They are SLRB's solid rocket booster engines. They use solid fuel stored internally
like fireworks. They are more energy efficient than the three liquid hydrogen/oxygen turbopump rocket motors used underneath the shuttle. But they have a small problem. Once you start them stand back, because you aren't shutting them down, you aren't even throttling them. Obviously they are not restartable.

But because of their higher efficiency though they are the wave of the future. The return moon mission seems to use ones like
them as a single stage to orbit launch rocket.

Actually, NASA has jumped on the "green" bandwagon and are developing their future as we speak: RAILGUNS!

Uses magnetism and electricity to launch the craft from grade, meaning total speed is not limited by shockwaves like jets and rockets are...

Railguns currently hold the all-time (unmanned) speed record of some 1700+ MPH if I remember correctly.

No Chet I'm not saying that and were does Archer have that, what I'm saying is I design a gate 10 or so years ago with the same principle as Archer one he designed 3 days ago and thats why it wasn't new to me.
Now I will answer questions before some goose says it, the principle is the same the difference is the type of magnets used and the advances in mine.
Archer uses cylinder magnets joined for his stator giving him one side north and the other south, I use block magnets joined giving me one side north the other south both the same just different types of magnets.
Archer uses cylinder magnet joined for his roller one side north the other south, I use donut magnets joined for my roller one side north the other south again both the same just different types of magnets.
Archer has a air gap then his magnetic setup is the same as the first. I have an airgap then my magnetic setup is the same as the first except my improvements again both the same.
My improvement first Archer said on his vid it was hard keeping the repelling magnets apart, I have a iron bar under my magnetic setup so it was easy to keep the repeling magnets apart.
Second I have iron and steel at the half way point of the second set of magnets this is to cut the field so the momentum takes it past and out.
The only difference between Archers setup and mine is mine is designed better to leave and keep everything in place and we use different types of magnets.
My was done over 10 years ago so thats why its old to me as I have said, someone may say something about the date but I think computer wizes can show the date the videos were made, if not the date on the site is proberly the last time the owner modified it and that date is march of this year which is 4 months ago so even that proves this was designed way before archer came up with it.
I hope that fixes all the douts that may come up.
Take Care Chet and all
Graham
PS: my system only shows it run on a level surface because in them days all people wanted to see is a gate on a level surface, because its the same principle as Archer given the same magnets it will do the same thing.

The two "tanks" on the side are solid fuel rockets. The big tank carries liquid fuel for the shuttles main engines.
