Though
less dense and
cooler than the hydrogen of a fusion reactor, the
wind is a plasma — and can be probed thanks to STEREO.
Yet increased energy efficiency and a focus on
wind and solar power, which require
less water, or the switch to more water efficient
cooling technologies could help avoid this problem, the study shows.
It was
less than 5 ° with a super
cool wind blowing so we took trial pictures with coat on.
There is also
less upwelling of
cool water from below the surface when the trade
winds weaken.
Winds: Warm air is
less dense and rises (equator),
Cool air is more dense and sinks (poles).
This change in the size and location of the coronal holes on the sun has resulted in
less solar
wind bursts and smaller magnitude solar
wind bursts which explains why there is suddenly high latitude
cooling.
Annual water requirements of a PHES - supported 100 % renewable electricity grid would be much
less than the current fossil fuel system, because
wind and PV do not require
cooling water.
The weaker trade
winds also draw
less cool water from below the surface.
Again for example, during multidecadal periods when El Niño events dominate, the tropical North Atlantic trade
winds would be on average weaker than «normal», there would be
less evaporation,
less cool subsurface waters would be drawn to the surface, and tropical North Atlantic sea surface temperatures would rise.
With light
winds, the
cooling is greater near the surface and
less aloft, while with stronger
winds, which are associated with greater mixing of the air above a particular location, the
cooling rate is more uniform with height.
This method of
cooling benefits from the low humidity, clear night skies, and rapid drop in ambient temperature that are common to this area (SW Montana), and would be
less effective in areas with higher night temperatures, high humidity, high
winds, and cloudier skis.
Cutting edge data centers of the future will require
less of a physical human presence, and are likely to: â $ cents Rely on a VIL to optimize equipment management and provide for virtual remote control capable of instant changes, switches and adds â $ cents Achieve LEED certification for the physical building â $ cents Rely on more efficient water
cooling that potentially takes advantage of an on - site tower to chill water for
cooling the system (thus reducing energy consumption by using nature's natural
cooling power to chill water) â $ cents Use fluid dynamics models to precisely design the interior of the building to maximize the efficiency of the HV / AC system for air -
cooled computing systems â $ cents Tap into a mixed energy grid that relies on green energy sources such as solar,
wind or hydroelectric (depending on geographic feasibility), along with a reliable city grid thus avoiding the need for the standard back - up Uninterruptible Power Supply (which will reduce equipment costs, minimize floor space used, and increase energy efficiency because systems that employ a UPS convert AC to DC and back, incurring substantial energy losses).
The solar
wind is 13 %
cooler and 20 %
less dense.
