Today marks a new era of space commerce. In the 1930s the DC3 enabled effective commercial air services. What will mark a comparable step in this era of space enterprise?

Aircraft that fly from a runway can reach space. Scaled Composites and Orbital Sciences Corporation have demonstrated this. Space tourism favors the comfort and confidence of runway operations. Captain Chesley "Sully" Sullenberger recently showed us how wings offer landing alternatives during a crisis.

Optimizing these designs will require unique aircraft types. Blended wing bodies are now being considered for structural and aerodynamic advantages. Horizontally launched spacecraft must lift high payloads with low drag and minimal wings. They are ideal candidates for efficient wing body configurations.

In the US every year 147 Million Gallons of Fuel are lost due to evaporation in the vehicle's tank. This simple design may help to reduce the surface area of the fuel in the tank at all times, thereby reducing the rate of fuel-evaporation.
A floating plastic plate on top of the fuel inside the fuel-tank, as shown in the diagram, will reduce the effective fluid (fuel) amount in contact with the atmosphere, thereby reducing the loss due to evaporation. The only opening in the centre is to allow for fuel/air entry as needed into the tank. Other openings can be had to allow for the fuel-pump, fuel-level sensors, etc. The cost of putting in such a perforated plate ...

Cars of the 21st century are emitting less and less pollution.Despite this, fossil fuel burning is still necessary to power the car and thus emit pollution.With the technology that we have today, it is impossible to have 0 emissions while burning fossil fuels.But alternatively, with the Fully Internal Combustion System (FICS), it traps the Car emissions in a pressurized air tank.When that air tank has reached its maximum capacity, it will be transported to a local CO2 Scrubber station to properly dispose of the harmful CO2 and release the clean air back into the Earth's atmosphere.It is only with the use of FICS that 0 emissions can be achievable.With the wide implentation of this technology, CO2 emissions from vehicles ...

Why struggle through the air when it can be swept out of your way in front of your vehicle? If you have ever driven in the slip stream of a truck you will know you don't need to be so heavy on the gas. About half the propulsion energy of a car is lost in air resistance. For an aircraft the proportion is much higher.

So how does my "excuser" system push the air sideways without putting a truck in the way? It uses a novel approach with a very familiar substance: water.

Water vapor at very high temperature and pressure is created by burning a two-to-one mixture of hydrogen and oxygen in a rocket combustion chamber. The exhaust ...

Grail Engine Technologies corporation has developed a revolutionary two-stroke internal combustion engine (ICE) that achieves high fuel efficiency (100+ mpg) and uses multiple fuel sources (i.e. gasoline, diesel, hydrogen, natural gas propane - electronically controlled on-the-fly)

Two-stroke ICE designs have been in production for generations but are being discontinued due to emissions. Our unique proprietary design operates without cross contamination of oil and fuel within the combustion chamber or exhaust cycle – the first of its kind. With improved volumetric efficiency, utilizing the “Miller Cycle” and HCCI (Homogeneous charged compressed ignition) simultaneously, our engine will produce more power than conventional four-stroke ICE’s. These benefits are high fuel efficiency, compact recyclable operating footprint, lower harmful emissions than currently mandated - ...

Vehicle propulsion systems are the integration of energy storage (diesel, gasoline, batteries etc) with energy transformation (chemical to mechanical, chemical to electrical to mechanical, etc) systems. For an electric (core technology) based vehicles, electric storage in batteries has been limiting. Power conversion from high voltage to high current systems used in existing designs are inefficient and the thick copper cabling required to carry such currents with little loss leads to extensive cost and weight issues.
Using a systems based approach to design and prior innovations by the PI, a power-train system has been designed and developed that is light weight with very high energy densities. A SuperUltraCapacitor, power controller, motor, charging system and regenerative braking system, all capable ...

Description

With over 50 years of development and literally tens of thousands of testers, roller coaster rail system technology has more than proven itself as a transportation technology. However, it has never been transitioned into use by a commercial or public sector transportation system. My proposal then is to adapt this green technology into a viable transportation system capable of successfully challenging our existing short and long haul passenger rail systems.

Innovation

The engineering science necessary to design new and more thrilling roller coasters for amusement park operators is being constantly being refined and improved. As this knowledge continues to evolve, so does the wealth of well-engineered, tested, and capable equipment. Passenger rail systems will benefit immensely from this ...

People and sensitive electronics traveling in space need protection from high energy radiation. Solid shielding materials are very dense.

I assume that a very small proportion of particles strike the craft at a right angle. My idea is to make some walls, bulkheads, floors, and unused interior volumes from honeycomb panels with cell walls containing energy-absorbing material, such as Hydrogen-loaded plastic. Some high energy particles would strike the cell walls one or more times and lose some energy with each strike. Smaller cross-sections and longer cells would get more strikes.

Spacecraft designers would "tune" each ship for it's mission parameters using honeycomb panels of various thickness and cell sizes, along with solid shielding, if needed.

The honeycomb structure might ...

Throughout recent history there were several attempts to build Jules Verne's vision of a space cannon, from Krupp's wartime Paris Gun as a weapon to the 60's Harp project as a space launch system.In recent decades the SHARP light gas gun and the current successor Quicklaunch project are all still unable to affordably and reliably achieve their goal.
My idea is to use a common old technology, the air gun, and some additional elements to propose an alternative way to reach success.
Normal cannons use chemical based propellants that provide high initial acceleration.This is bad because of the high G force tolerant components required to make any good use of it. An air gun can be regulated to ...

This system works as a straw. When you put the finger at the straw’s upper end, the liquid does not drop because of the air pressure. Fig 1 presents the system at quiet state. We organize the set so it takes the lesser space on board. The entire set (missile, piston, empty cylinder and flexible pipe) stands on 2 bearings. It is retained under high compressed air. In case of emergency (fire, shocks and so on), the air pressure (Fig 2) ejects the set faraway 300 meters off the tanker. After that, incorporated electronic circuit triggers the missile in a safe way. The missile pulls up the piston so the petrol is aspired from the tanker through the flexible ...
