The real question is do we have the will to listen, and the convection to respond.
Unlike Dr Hallett's convection-grown snowflakes, Dr Libbrecht's electrically generated crystals have no obvious applications.
The work of convection is captured with turbines located at ground level around the periphery of the arena.
FORBES: Peter Thiel Funds Effort To Tap Tornado Power To Generate Electricity
Long thin tubes, called convection zones, spiral up the inside of the cylinders, gathering nautical winds and generating electricity in the process.
It is a convection oven for even cooking, a toaster, a broiler, a microwave, and range hood all in one powerful appliance.
ENGADGET: Samsung debuts T9000 refrigerator with LCD and Evernote integration
The new Generation III reactors such as the AP1000 have a simplified "passive" cooling system where the water circulates by natural convection with no pumping required.
Key to Bassoul's plan was buying Blodgett--a market leader in convection ovens, ranges and charbroilers--which was 25% bigger than Middleby, owned by Maytag and, rumor had it, doing poorly.
The air is so thin that the first glimmer of sun can throw it into violent convection, lofting up into towering thermals, twisting into dust devils, and collapsing back down as they cool.
If a funnel cloud touches the ground it is generally regarded as a tornado and could lift debris and even cause some minor damage on the ground - depending on the strength of convection within the cloud.
Some researchers have suggested that materials produced in the Sun's atmosphere are pulled into the star's interior, where they circulate in convection currents for millions of years before making their way back to the outer atmospheric layers.
Scientists speculate that the silicates stuck to the mantle might also be caught up in mantle convection and carried to the surface, accounting for reports of core material in lava erupting from hot, spot plumes, like those under Hawaii.
For instance, when you do combustion studies, flames on Earth burn in a teardrop fashion because the air comes in from underneath it and feeds the flame, but we can't do that here since the air doesn't know where up is, there's no convection.
