Replacement Firearm for Non Front Line Troops

My idea is for a new military service sidearm. The US Army will be converting over to the more powerful XM7 rifle for combat use. This gun has higher bullet energy to deal with body armor. For support troops, the current M16 rifle and 9mm handgun will be retained.

Optimal RF Receiver

The concept of an optimal receiver has long been a theoretical goal for RF engineers and scientists, dating back more than a century. An optimal receiver is characterized by its ability to adjust major parameters to match the characteristics of the receiving signal, thereby optimizing spectrum usage and the receiving process. However,

Sustainable Personal Air Mobility… NOW!!!

NFTG is developing a simple, ultra-quiet, personal air vehicle and drone, capable of rapid door-to-door mobility without requiring any operator license.

It will be powered by one of our patented rotary engines or ultra-efficient and ultra-power-dense turbo-engines of my design.

Solid Hybrid Motor

With an Isp of 175 sec with a density Isp of 1.5, it creates a rocket motor 1/2 the size of a normal solid propellant motor. Although low in Isp, this combination has a very high density Isp making it possible to reduce the size of a known total impuilse by ½.

Ballistic Liquefied Inert Gas Wildfire Suppression System

This proposal would fill a ballistic projectile ie artillery or mortar shell with a liquefied inert gas, and fire it upwind of an isolated wildfire. The projectile would not detonate but would disperse LIG over the hot spot. This would cool the fire and displace air thereby removing two elements of the fire triangle, heat and O2 (fig 1).

Planetary Defense - Interstellar Object Sentinel

This entry concerns the safety of life on the planet. It proposes action to improve our awareness of potential threats from near earth objects in space by asserting the need for an early warning scanning capability that covers all directions.

The recent 2017 discovery of ‘Oumuamua, the first known interstellar object to enter our solar system, is pertinent.

Photonic Cyclogyro-Like Spacecraft

I introduce another type of solar-photon spacecraft, differing from the solar sail or heliofoil.

Consider a rotating cylinder rotating along an axis perpendicular to oncoming light. The portion of the reflected light from the part of the cylinder rotating into the light is blue-shifted and the part that is rotating away is red-shifted.

CBAG (Configurable Buoyancy And Geometry) Airship

The CBAG (Configurable Buoyancy And Geometry) semi-rigid airship overcomes all of the disadvantages of earlier airships. It is simpler, lighter, stronger, smaller, cheaper, and several times faster than any rigid or non-rigid air-ship of a similar load capacity.

Motion Detector

Aircraft and other vehicles are out of control. The loss of property and lives is very costly. Why do drivers pull out at a stop sign into the paths of motorcyclists? How can a person unwittingly crash into a brick wall with their foot on the accelerator?
