Gizmag: Could Earth's infrared emissions be a new renewable energy source?
Hur menar man med detta resonemang?
I synnerhet att en högre termperatur hos en diod än en resistans skulle pressa fram en ström?
För att åstadkomma detta verkar tunnel- och ballistiska dioder vara en del av lösningen. Är det någon som sett sådana till salu? kostnad?Gunn’s diagrams show that if a diode is at a higher temperature than a resistor, a current will be pushed towards the cooler component. Using this idea, Capasso has suggested that microscopic antenna pointed toward the sky could be used to cool areas of a circuit, which would create directional flow as proposed by Gunn.
But with new types of diodes already being designed that can handle lower voltages, such as tunnel diodes and ballistic diodes, this challenge may soon be overcome.
