It looks like a hair dryer from Mars.

This makes moist air generally less stable than dry air (see convective available potential energy).

Industrial designer Brooks Stevens developed the first electric dryer with a glass window in the 1940s.

Red dwarf stars with less than 0.4 are convective throughout, which prevents the accumulation of a helium core.

The existence of a corona appears to be dependent on a convective zone in the outer layers of the star.

For most stars the convective zones will also vary over time as the star ages and the constitution of the interior is modified.

Dragon Storm (dubbed so in September 2004 because of its unusual shape) is a large, bright and complex convective storm in Saturn's southern hemisphere.

However, instead of exhausting this air, the dryer uses a heat exchanger to cool the air and condense the water vapor into either a drain pipe or a collection tank.

So they ended up an Iron Age European society, virtually unable to make their own iron. A second item on my checklist is climate change. Climate can get warmer or colder or dryer or wetter.

That justification will not convince economists, who prefer a dryer sort of reasoning. But it is not out of place to remind ourselves that economists and bureaucrats need not always have things their own way.

In the United States, the U.S. Fire Administration in a 2007 report estimated that clothes dryer fires account for about 15,600 structure fires, 15 deaths, and 400 injuries annually, with 80 (12,700) of the fires in residential buildings.

With such a battery, an average electric ray may electrocute larger prey with a current of up to 30 amperes and a voltage of 50 to 200 volts, a similar effect to dropping a mains powered hair dryer into a bathtub.
