By assembling off the shelf technology, we can project pewer to a flying saucer that then can use it for propulsion
Powering a flying saucer from a remote source allows for a light and fast craft
When all is considered, for most applications, the flying saucer is powered remotely. Energy is beamed to the vehicle from a source where it is created as a result of some process like fusion, solar concentration or even the burning of oil and coal. We would hope that environmentally friendly processes would be used to generate the energy for powering the craft with a remote fueling source. Flying saucers by their nature and high speed, consume a lot of energy. It is hopeless to power such a craft with on board fuel as the mass would be far to limiting. Consider the ponderous rocket that is 98 percent fuel and 2 percent payload just for low earth orbit. Now consider keeping the 98 percent on the ground and launching the 2 percent by another method free of cumbersome quantities of fuel.. Nikola Tesla did consider this and came up with working plans on how it could be achieved. For him, it was all about the wireless transmission of power and resonance. That was almost achieved at Wardenclyffe, but was ultimately smashed by J. P. Morgan. We already have the off the shelf technology for this.
On the ground we have massive power stations that generate huge amounts of energy to run cities and particle colliders like the LHC in Switzerland. These energy converters run on coal, oil, geothermal, wind, tidal, nuclear, hydro and solar sources. This alone is impressive. New power facilities and types are coming on line. Couple some of these with a MASER and you have the makings of a remote fuel-energy transfer system.
Even if you only use a turbofan in your vehicle, if you have a fractal antenna-rectenna-inverter assembly, you are good to go as long as you are receiving the MASER energy to the antenna. If you think a turbofan flying saucer will not work, consider how the Harrier Jump Jet can hover. Without the ability to redirect thrust, the hovering jump jet would be in catastrophic stall. But turbofans work only in the atmosphere of the earth. To get into outer space, a different propulsion system is needed. That choice boils down to either a magnetic drive, magnetohydrodynamic propulsion, a momentum converter, a plasma drive or an ion drive. In each of these cases, some on board storage of power can be accomplished with batteries or fuel cells. This is for use in emergencies. Otherwise, all the power comes from a remote source.
On the ground, the MASER would be aimed with a directional and linked antenna that beams the coherent electromagnetic energy directly to the flying saucer. It stands to reason, that there would be continuous communication to the ground and the vehicle to have an uninterrupted source of energy, crucial for flight in the atmosphere and near earth space. In space, for larger vehicles, energy may be manufactured on the vehicle itself, powered by the sun or from background radiation. Bear in mind, in the weightlessness of space, a lot less energy can do far more than in a gravity well of a planet or moon. If the flying saucer is also built with little mass, the same would hold where less energy can do more. This concept was vindicated with an ion propulsion vehicle used for comet chasing. It was fueled only by solar panels. That ion propelled vehicle broke all space speed records to this day, traveling at 70,000 kilometers per hour relative to the earth at its greatest speed. Conceivably, a flying saucer can be built to do the same and more. If a vehicle can be accelerated at one gravity constantly, then a round trip to Mars and back when Mars was at the closest approach to earth would take a week to accomplish instead of the 18 months for more ponderous methods. A trip to the moon would only take a few hours.
On board the space faring saucer, we have several systems consisting of, the human life support technology that is currently in use on the ISS. Considering the foregoing, a large saucer could transport several astronauts to Mars with a lengthy stay over just with the constraints we have now with the ISS. There is also the rectenna, the inverter, the circuits to store, alter and to power everything and the engine itself to provide the thrust. Of the five space propulsion systems mentioned, the magnetic, magnetohydrodynamic propulsion and plasma drives are the most energy hungry. But this has the advantage of quick take off, flight path change and stopping of the other two. Ion drives, though efficient, are meant for long haul slow acceleration trips used with the space super highway where sudden changes are not important. The momentum converter is purely mechanical and somewhat primitive when considered with the other four. There is the communication control linked to the fuel source, pilot-ground communication and orientation systems. The saucer would have an internal stabilizer to keep it in the right alignment. On some designs, part of the saucer would be rotating and this alone would provide the stability.
Consider the popular toy Frisbee. This toy quickly achieves gyroscopic stability, no matter how crudely thrown and maintains its initial orientation as long as it spins. It is also designed to create lift so that long throw flights are possible. Though surprisingly simple in profile, it's dynamic flight capabilities are quite spectacular. Scaled up and given some form of continuous thrust, this simple form can be the foundation of air flight in the immediate future it it isn't already a fact. A ground based fuel source that generates energy that is then transmitted to this saucer will go far in making it practicable. It will be light as it carries no fuel. The fuel used to create energy can be geothermal or solar, making the whole process environmentally friendly. Geothermal plants already exist as do solar ones and these can be back converted to power these saucers, or, alternatively, new ones constructed for just that purposes.
Geothermal plants use the heat of the magma that is close to the surface of the earth to turn water into steam that then drives steam turbines. The turbines linked to generators create the electrical power to power a MASER. Today, many types of MASERs exist and we can chose one form to be resonant with an antenne-rectenna assembly on board the flying saucer. One popular MASER is the hydrogen MASER that can readily be used with a matched resonant antenna to pass on energy to an airborne of space borne craft.
