All that comes out of the tailpipe is a little trickle of water and water vapor.
Scientists have previously established the existence of water on Mars in the form of ice at the poles and water vapor, and pointed to geological features that appear to have been carved by water ages ago.
One major unsettled issue in climate science indeed is what this sensitivity is, and several threads of information, including the surface temperature history, and water vapor and cloud data argue Lindzen may be correct.
FORBES: What Happens When You Rub Two Climatologists Together?
The architects worked with Pureti, a green-tech manufacturer (and winner of a 2011 "What's New" award from Popular Science), to develop a spray version of a titanium nano particle that, when activated by sunlight, oxidizes airborne particulates and converts them into water vapor and trace amounts of carbon dioxide.
The gas is then fed into a stack of solid oxide fuel cells, where a chemical reaction between hydrogen and oxygen occurs, producing electricity, water vapor and a tiny amount of carbon dioxide.
The spectrometers can catalog potential life signature gases such as carbon dioxide, methane and water vapor.
Injected into the exhaust stream, the solution's ammonia reacts in the de-NOx catalyzer to form nitrogen and water vapor.

If you oxidize any hydrocarbon, you generally produce heat, carbon dioxide, and water vapor, assuming a relatively pure fuel source.
FORBES: On Romney's 'Rising Oceans', Time To Get A Bigger Boat
In 1863 the Irish scientist John Tyndall determined that carbon dioxide and water vapor trapped more heat in the atmosphere as their concentrations increased.
The much larger warmings forecast by IPCC require a major increase in atmospheric water vapor and warming clouds.

On Earth, the volcanoes filled the air with water vapor and carbon dioxide.
What is known is that 3.5 billion years ago, Crotts says, the moon regularly spewed forth large amounts of water vapor and sulfur dioxide through volcanic surface vents.
FORBES: Active Moon? Recent Lunar Surface Phenomena May Signal Some Form Of Volcanism
As a result, the astronomers demonstrated in their research that the JWST should be able to detect the presence of water vapor and oxygen in an atmosphere in just a few hours of observation.
By 2020 or so, depending on the progress of fuel cell technology, the last of the island's 9, 500 gasoline cars will be gone and only water-vapor-emitting fuel cell autos will remain, according to Taniguchi's plan.
Ocean hits are worse than land hits, not just because of immense tidal waves, but because of the vast quantities of super-heated water vapor and dust that spread from the impact to shroud the entire Earth.
Geothermal power plants turn hot water into steam or vapor to run a turbine and generate electricity, after which the water is injected back into the underground geothermal reservoir.
Clean, silent, (well, OK, a high-pitched whistling sound), uses no fuel whatsoever, except hydrogen, the most plentiful element on the planet, and emits only water vapor.
FORBES: Disappointed With Electric Cars, Automakers Are Making Bad Bet On Fuel Cells
In the tropics, they take up water from the deep soil and release it as vapor in the air.
Water vapor is a potent greenhouse gas and will absorb yet more heat.
Further differentiating itself from our world's whirlwinds, this alien cyclone is locked to its planet's north pole and is fueled by small amounts of water vapor instead of an actual ocean.
An ingenious new laser called Waterlase adds to that the ability to cut through dry teeth and bone by casting a cloud of hot water vapor around the laser's cutting point, a couple of millimeters from the tooth.
Also a type of electric vehicle, a fuel-cell car takes hydrogen gas and converts it into electricity, while emitting only water vapor.
CNN: Hydrogen fuel-cell cars look to overtake electric autos
So Feldstein invented a system that pressurizes a small amount of water and pushes it through tiny nozzles, atomizing it into vapor.
Hurricanes thrive on water and wind -- specifically, warm ocean temperatures and vapor swirled up into the atmosphere by ocean surface winds.
And they are an exceptionally clean power source, producing only water vapor as waste.
Now most of that increase occurred after 1970, and it's an indication that there's more water vapor in the atmosphere so that these storms get invigorated.
And the only thing that comes out of the tailpipe would be water vapor.
