High-Concentration Photovoltaic Thermal System From IBM Promises 80% Efficiency, Potable Water, And Air Conditioning
By utilizing such a high concentration of sunlight, and the rather low cost of the design, the researchers think that they can realize a cost per aperture area under $250 per square meter — that is roughly 3 times lower than in similar systems.
How Things Work: Acoustic levitation
Because sound waves are mechanical, they require a medium to travel through, such as a gas or a solid, and are made up of two alternating parts called ... forming an area of high pressure, due to the high concentration of gas particles.
How High Ozone Concentration Makes it Easier to Dissolve Ozone in Water
The process of dissolving ozone in water is optimized by maximizing the surface area ... (high concentration) the system does not need to use as big pumps as previously. Higher pressure improves the dissolution as well. This could be used to move the ...
Turning smokestack emissions into sources of energy
The idea behind smokestack gas extraction grew out of a technology called blue energy, which is based on the principle of osmosis: Particles move spontaneously from areas of high concentration to areas of low concentration. "If you take a lump of sugar and ...
Controlling Dust With Curtain Walls
From a safety standpoint, there are many circumstances where high enough concentration of airborne ... velocity airflow stream captures particles and recirculates them through a filter medium, where they are removed. Area exhaust – a high volume exhaust ...
