Can microwaves be more efficient at driving steam pushed turbines than fossil fuels alone?

No , I think ? Microwaves would not have enough forces ???? Any way it would be insreresting to research   Go for it !!!!!!!!!!!!!!!!!!!

Yes the low steam temperature improve the condenser vacuum because the density of the steam will decries and the vacuum efficiency will increase.\nBut you will face another thing the at the low pressure turbine (LP) exit, the moisture will increase and the work of the turbine will be little down!!

Simply because microwave radiations impart energy to atoms and molecules in the crystal structure. Materials which can withstand the induced extra energy are safe, others are not.

Wow! That's quite a question!\nOkay -- let's assume we're dealing with an electric stove. The elements on the stove heat up and are in direct contact with the cooking utensil. That's conduction. Microwave ovens work by agitating the tiny little particles in the food, and this is what generates the heat and cooks the food. \nThe toaster works by radiation -- the element heats up and radiates heat, which then cooks the surface of the bun, bagel, bread or whatever. \nIt's difficult to measure the environmental impact of modern appliances against those of previous generations. For example, where does the electricity come from? Is it generated by hydro power, or by a fossil-fuel powered generator? Availability? Previous generations used a lot of wood. It was cheap, you could usually cut your own, and was readily available. But it generated a lot of smoke. Coal was even worse. Solar powered appliances (and there are a few around, such as water heaters and solar cookers) are probably the most environmentally kind, but they are expensive and, obviously depend on a constant supply of solar energy, sso that limits their general effectiveness. \nHope this gives you a few avenues to explore.

The fuel should increase to take the load. My experience is on turbine generators, one was 9 mega. WATS.

Of course it is.  It is done all the time at Iofe Institute in St. Petersburg Russia, where they have continued research into this in the field of lasers and semi conductors (as a parallel pursuit).  Also with burst technology.  Also, the Japanese physicist Hidetsugu Yagi did a lot of work in the field. \n\nHowever, I am not sure whether you are talking about energy that can then be used by a consumer or high energy antanae, which is already a reality.

Steam turbines have several controlled nozzles which connect to the superheated steam source from the boiler and superheater.  The number of nozzles and steam flow rate through the nozzles can control the power output of the turbine.  The momentum of the steam gas hitting the turbine (in stages) as it expands spins the turbine creating shaft power.\n\nOne type of gas turbine is the exhaust side of a turbocharger.  Hot exhaust gas under pressure is pumped by the engine into the the outer ring of the turbine.  The gas is still expanding, and spins the turbine providing shaft power to drive the air compressor side.  \n\nThe type of gas turbine common to power plants and airplanes has a compressor section, combustion chamber, and expansion section.  The expansion and compression turbine sections have moving vanes and stationary vanes to direct the gases and extract the most work possible from the setup.  Atmospheric air is compressed by the compressor and fed at elevated pressure to the combustion chamber where fuel is injected and an ingnition source keeps the flame lit.  The exhaust spins the expansion section and exits through the rear of the engine.

The 1800 has double the energy emission but both are pretty much negligable to the human anatomy\n\nAnd no, being near microwave-oven frequencies doesn't matter. Many many wireless consumer items use the 2.4ghz frequency and no ones brain is being fried.... unless you're infront of the tv 12 hours a day... but that's a differnet story

Your first paragraph is quite true. Tesla patented various methods for transmitting power using large resonators with local "receivers."  If you have a resonant cavity you can get pretty good coupling between source and receiver (microwave oven for example).  The general use for power distribution has its problems, not least of which is how do you charge($) the receiver?\n\nThe analogy of sympathetic vibration is valid.\n\nNot sure what to make of the magnetism bit.\n\nElectrons resonate - they may in fact be "resonances"\n\nOur entire electrical power system is based on Electricity and Magnetism so I think the answer is yes we can pick up energy.\n\nWhat may be missing is that we also have to provide the energy up front before we get to pick it up!

I believe it will be possible. The first application of the development of such technology will be the transportation of mass amount of fluids, and solid materials from one place to another. Granted, these materials will probably be simple materials without complexed molecular structure but, it will be the place that other developement will continue from.\n  The technology is centries into the future if it is that soon. The general idea is simple. Breaking down atomic structure in a trasmitable format, transmitting, then reconstituting teh transmitted. It then is a matter of what atomic partical belongs on what part of the carrier wave of the radio/or microwave transmitter. Another additive to the  complexity, is actually getting the particals on the carrier wave. However, if modern modems can convert digital signals into anolog, and analog into digital signals, then other parts of a "transporter" is a matter of time.\nSide note on this: If it will require the power produced from anti-matter generators, then it should interest all that a few anti-matter atoms had been produced. It took more energy to produce those few anti-atoms then they could produce themselves, but it does illistrate that Star-Trek to Star Wars technologies are not entirely impossible.

It is possible, since electromagnetic waves carry energy, although you are not really sending electricity, more just transferring energy. Having solar collectors in space that 'beam' energy to earth via microwaves (high refrequency radio waves) has been seriously considered.\n\nAny solar panel is also converting electromagnetic waves to electricity, os the answer is definitely yes.
556956
Yes!\n\nAs it turns out, radio waves are nothing more\nthan the propagation of electrical and magnetic\nfields through space--the E & M fields perform\nan intricate dance around each other and fly\nthrough space.  So yes, you can transmit\nenergy through the air and "catch it" with\na receiver antenna. That's exactly\nwhat a microwave oven does:  the business\nend of a microwave is a transmitter and antenna,\nand the food is the receiver.\n\nI suspect the energy needed to propel\na car-sized vehicle, however, would involve \ndangerous amounts of power.  Any bird, pet,\nor human which passed between transmitter and\nvehicle would be zapped.  Streets\nwould be littered with smoking corpses, and\nyou'd smell BBQ all day.\n\nBut hey, BBQ ain't a bad thing!

Depends on what you mean by better.  I would say neither actually, because they both produce dangerous waste products.  Nuclear breeder reactors are probably the safest way to produce energy (limiting myself to the two choices you provided) since there are no dangerous byproducts.  Unfortunately, both of these energy forms are from limited resources (as far as we know).  I think we should be tapping into wind and solar (particularly) more than rather finite, polluting energy sources.  Hell, why not build solar fields on the opposite side of the moon and beam the energy via satellites and microwaves?  Oh well, what do I know?

Mechanical energy is produced when heat is carried upward by convection in the atmosphere. A process for producing a tornado-like vortex and concentrating mechanical energy where it can be captured is proposed. The existence of tornadoes proves that low intensity solar radiation can produce concentrated mechanical energy. It should be possible to control a naturally occurring process. Controlling where mechanical energy is produced in the atmosphere offers the possibility of harnessing solar energy without having to use solar collectors.  \nThe Atmospheric Vortex Engine (AVE) is a process for capturing the mechanical energy which could be produced when heat is carried upward by convection in the atmosphere. The AVE process is protected by patent applications and could become a major source of electrical energy. The unit cost of electrical energy produced with an atmospheric vortex engine could be half the cost of the next most economical alternative.  \nA vortex engine is a machine for producing and controlling a tornado-like vortex. A vortex engine consists of a cylindrical wall open at the top and with tangential air entries around its base. Heating the air within the wall using a temporary heat source such as steam starts the vortex. The heat to sustain the vortex once established is provided in cooling tower bays located outside of the cylindrical wall and upstream of the deflectors. The continuous heat source for the peripheral heat exchanger can be waste industrial heat or warm seawater. The intensity of the vortex is regulated by restricting the flow of air with dampers located upstream of the deflectors. The vortex can be stopped by restricting the airflow to deflectors with direct orientation and by opening the airflow to deflectors with reverse orientation.  \nElectrical energy is produced in turbo-expanders located in the inlet to the cooling tower bays. The pressure at the base of the vortex is less than ambient pressure because of the buoyancy of the rising air. The pressure in the cooling tower bays is sub-atmospheric because the cooling bays exhausts at the base of the vortex. The Atmospheric Vortex Engine has the same thermodynamic basis as the solar chimney. The physical tube of the solar chimney is replaced by centrifugal force in the vortex and the atmospheric boundary layer acts as the solar collector.  \nThe average upward convective heat flux at the bottom atmosphere is 150 W/m2, one sixth of this heat could be converted to work while it is carried upward by convection. The heat to work conversion efficiency of the atmospheric heat to work conversion process is approximately 15% because the heat is received at an average temperature of 15 C and given up at an average temperature of -15 C. The average work that could be produced in the atmosphere is therefore 25 W/m2. The total mechanical energy produced in the atmosphere is 12000 TW (25 W/m2 x 510 x 1012 m2) whereas the total work produced by humans is 2 TW. The quantity of mechanical energy which could be produced in the atmosphere is 6000 times greater than the mechanical energy produced by humans.  \nProducing and capturing the work requires that the expansion process be carried out at mechanical equilibrium. Without a mechanism, such as a turbine, to capture the work of expansion and to ensure that the process is carried out at mechanical equilibrium, the mechanical energy is dissipated and lost. \nAtmospheric scientists call the mechanical energy that would be produced if a unit mass of air were raised reversibly from the bottom to the top of the troposphere Convective Available Potential Energy (CAPE). CAPE during periods of insolation or active convection is typically 1500 J/kg which is equal to the mechanical energy produced by lowering a kilogram of water 150 m. It is proposed that a vortex could transfer the mechanical energy down to the Earth's surface where it would be captured.  \nThe process could provide large quantity of renewable ener
