No. The simple Magnetic & Electric Repulsion can create an antigravity and electro Magnetic flight. For exmple "hot air balloon" (an early form of anti-gravity) can rise up through the Earth's atmosphere... Using "Electricity "for fuel, which requires "super-conductivity" for efficiency, and "batteries" as "fuel tanks" to hold the electricity necessary to start it's "solid state electronic motors"
It Would be possible to construct a craft with small enough propulsion power requirements that interstellar travel could be achieved.

Here simple explanation A crsft that when in flight, can generate all the electricity it needs and recharge its batteries, just from its motion... A craft that once outside the Earth's atmosphere, flies at electromagnetic speeds.
If you believe or some other abstract theory, you will never understand antigravity or electro-magnetic craft... It is necessary to understand gravity as a simple electro-magnetic force, to understand the principles of antigravity and electro-magnetic craft.
It all by manipulating!

And being generated by the mass of the sun. But I never mentioned on petrol engine. Just an example on hot air balloon.

There's a big difference here. The effects of x-rays are measurable and replicable. Meaning that anyone that had the right equipment could recreate the devices and verify the findings.

All you have are designs and theories that doesn't work.

With regards to this topic: "Secrets of Anti-Gravity Propulsion, Telsa, Ufos & Classified Aerospace Technology" by Dr. Paul Laviolette. 

Basically they ran an electric coil through the leading edge of the wings to create a positive charge -- thus electrifying the skin of the aircraft. Then, they created a negative charge back by the exhaust somewhere and the two charges together create an anti-grav field.

And also  there is some form of ionizing device fitted into the leading edges so that resistance/friction is also reduced.

It's an amazing piece of machinery.

Apparently this is also one of the reasons that ground crews are not allowed near the plane once it lands for a considerable period of time, due to the skin of the plane still holding an immense charge.

The book, it's extremely interesting.

Actually the photo actually looks authentic if it was a infrared night vision image. The bright area would be hottest part of the plane since that is where the engines are located.

Best way to sell a story is to mix in the truth with the made up bits. That way it won't look too unbelievable. Better yet throw in a few scientific phrases that is authentic and hard to understand just to spice it up.

Could it be an active infrared night vision photo? The example from the link below show the difference between regular and active infrared technology. The one with the active infrared looks like a well lit room compared to the regular one.

You missed the entire point of my post. Brown's work has nothing to do with anti-gravity. If you are basing everything on Brown's work, your whole argument is based on wrong information since it has nothing to do with anti-gravity to begin with.

You didn't even get the reason why ion propulsion does not work in vacuum right. It needs gasses to ionize in order to produce ions. The atmosphere is not rich in ions. Ions don't last long in the atmosphere because it is unstable.

There's no proof that B-2s uses ions to improve its propulsion. The B-2 has nothing to do with Brown's work at all.

This example is based on several example of propulsion system from "The Secrets of Antigravity Propulsion." Page 152.

The flying craft would be moved forward by creating a gravity well or "gravity gradient". The craft, along with it's occupant, fall into the gravity well together, i.e. move forward together. To the passenger inside the craft there is no sense of falling and no sense of direction changes, no "G-Forces with straning faces of grunting passengers struggling to remain conscious by tightening the lower muscles of the body to retain blood in the brain. The craft can change direction instantly in sharp zipping turns and the passengers would not feel the changes of direction relative to the craft.

The "Gravity Well" is created through gradient differences by a charged ion field generated in front of the craft shown by +(plus) signs. The "Gravity Hill" is the dense jet of charged -(negative) ions thrust out behind the craft.

A gravity gradient is created between the negative hill and the positive well drawing the craft and occupants in the direction of the Gravity Well.
