It doesn't violate thermodynamics any more than accelerating a car

So .. from where does the light obtain the energy?

I asked the question .. if the light is gaining energy, from where does it
gain it?

From where the hell does your car gain energy when you put your foot down?

So light has a petrol tank and an internal combustion engine?

Where the hell does a maglev train get its energy as it accelerates?

Depends on the maglev's location -- and the power plant supplying the
tracks. There are a fair number of possible variants.

[1] Coal. Burn the coal, turn a turbine with steam
connected to a generator (a lot of these use steam as
an intermediary), feed the tracks. Radioactivity in
coal (mostly thorium) is problematic; fly ash has to
be trapped and handled. Coal can be and usually
is pulverized to increase burning efficiency.
The CO2 contributes to global warming.

[2] Oil. Rarely used in stationary applications, but
similar to coal in most respects. Oil is more
useful as a local fuel source (e.g., diesel-powered
locomotives). Contributes to global warming as well.

[3] Hydroelectric. Build big dam, pipe water therefrom
through turbines for flood control and electrical
generation. Eventually silts up.

[4] Nuclear power. The fuel is very energy dense but
the ecological consequences of mining it are problematic;
the waste disposal is a hot potato as well, though a
little less problematic than coal, as it's not gaseous.
Most nuclear plants use a double-heatflow system, to reduce
risk of exposure. Plants require lengthy approval processes
in the US.

[5] Fusion power. This wisp has been pursued for decades,
and has yet to be realized at a commercial level,
but ITER is giving its go, and maybe we'll get lucky.
Promises virtually unlimited power -- but coal is
still cheaper, at present.

[6] Biomass. Limited but probably cleaner than letting
organic waste rot. Variants include biodiesel and ethanol.
The mechanism is similar to coal and oil.

[7] Natural gas. A byproduct of oil extraction and
decomposition (which can be harnessed from capped
landfills), natural gas is a clean, easily pipable
fuel, mostly used for cooking and heating but can also
be used for power generation, either by a steam boiler or
directly feeding it into a reciprocating piston engine.

[8] Photovoltaic solar power. Silicon cells pointed at
the sun extract energy and feed it into the grid.
A proven technology at very low power levels (e.g.,
a pocket calculator); a bit too expensive compared
to other technologies for practical use beyond a few
megawatts, though research is continuing, and some
PV plants have been built to harness an otherwise
essentially free resource. Too bad the PV panel
construction currently swamps the profits.

[9] Thermosolar power. This idea is simpler than
photovoltaic: an oil or other such fluid flows through
a tube surrounded by huge tiltable mirrors, which
direct sunlight onto the fluid and warm it to over the
boiling point of water. A heat exchanger extracts the
heat and powers a turbine, much like coal or nuclear.
Very clean, but not useful on cloudy days.

[10] Geothermal. Steam vents are harnessed to extract
power from the heat of the Earth. Useful if one has
a steam vent or volcano nearby.

[11] Tidal. Tidal flows, caused by the Moon, are
intercepted with strategically placed baffles and
turbines. Not all that useful inland.

[12] Wind power. Basically solar, picked up by big
turbines rotating through the atmosphere, extracting
power from the wind. Useless on calm days, though
easily harnessable by small power units (e.g.,
traditional wind-driven water pumps and grain grinding
equipment).

[13] Human power. A man or woman turns a motor, getting
exercise and powering equipment. Useful on a very
small scale for such things as exercise bicycles
and treadmills; can power LED indicators but not
much else. Some experimental units may be available
in places such as the Exploratorium in San Francisco,
to demonstrate the concept.

[14] Hydrogen. Note that this is *NOT* an energy source,
but an energy conduit. Occasionally mentioned as a
clean-burning source for vehicles. Does not occur
in nature.

[15] Chemical batteries. Again, not an energy source.
Lower range than hydrogen.

[16] Capacitors. Not an energy source. Even lower range
than batteries.

[17] Flywheel batteries. This interesting idea basically spins up
a heavy weight inside of a closed container, the weight can
then have its power extracted through a generator. As the weight
loses energy the spin slows. Obviously not an energy source.

[18] Compressed air. Not an energy source. Fed through
an engine and then exhausted; the exhaust can be used
to cool the car's interior if necessary.

There's a few others but this should give you the idea. No power, no
maglev; no maglev, no movement. It probably wouldn't even levitate.


When light speeds up, the 'medium' that causes it slows down.

So are you saying in extinction that sometimes light 'steals' momentum from
the gas that is passes thru and sometimes the gas steal momentum from the
light, and that the gas and/or the light somehow know which way that has to
be (ie the gas known not to slow down light travelling < c and only slow
down light going > c and always it manages to slow it down to exactly the
correct amount.

Of course. ..just balance the momentum equation.....

And the energy equation. Or hasn't it occurred to you that
(in a Newtonian universe) it takes more energy to speed up
light from c to c+v than to speed up light from c-v to c?


That seems very fanciful.

To someone with no knowledge of physics it would.
