In 1923 Professor Paul Biefeld and his student Thomas Townsend Brown discovered this effect during the test of a new type of capacitor. Basically the Biefeld Brown effect is electro gravitation.

If there's thrust here then, it should boost these.

This isn't so much a design than it is a question: it is entered in this contest so it can be examined and rejoined by individuals skilled in the arts.

Consider: the Laval – a tube having a converging section,

My idea is an emergency parachute for Paragliders(PG) with a variety of electronic sensors and AI based, data processing CPU which is responsible to recognize dangerous situations automatically in the air and additionally a remote controlled trigger for SIV-Courses and PG school trainings.

Ceramics have been integral in the aerospace industry due to their low-density, high compressive strength and thermal stability. However, their range of applications currently remains limited due to their generally brittle fracture behavior. Structures in nature, such as mollusk shells and enamels, have unusual combinations of stiffness, strength,

My submission is for a carbon neutral commercial aircraft propulsion. The propeller aircraft gave way to the jet mainly due to the large speed difference between the two. Propellers became inefficient at higher speeds such as Mach .

An aviation design that was overlooked for decades is now the rage with the latest in fighters, stealth and UAV fighter escort fuselages. These can carry more passengers, cargo, fuel, instruments and/or weapons and do some of the lifting of the craft and load as well.

Clean air is better than dirty air, so it’s wise to reduce emissions. It will take decades to deploy sufficient infrastructure to eliminate internal combustion, however. By the time it’s completed, advances in engineered and bio-fuels will reduce emissions sufficiently to keep internal combustion relevant.

This article will not dispute climate change cause by greenhouse gases, but shed light on a new theory in the cause of raising temperature. Earth rising in temperature is not only causd by greenhouse gases, but also by the Planetary Orbital Misalignment. What is Planetary orbital Misalignment?

The “Comet Towed Ion Propelled Spacecraft” is a concept design for a spacecraft utilizing a combination of modified solar power arrays (for onboard energy production) and ion propulsion thrusters (for thrust and speed),

The concept of an inertial propulsion spacecraft was developed in response to the limitations of propulsion in the form of low- or high-temperature plasma recoil in current rocket propulsion systems.
