Eneco chip to convert heat to energy?

While it's impossible to completely disregard the firm's miraculous claims just yet, we certainly aren't sold on the micro-sized "solid state energy conversion / generation chip, which will convert heat directly into electricity or alternatively refrigerate down to -200 degrees Celsius when electricity is applied." Investors from around the globe have flocked to witness this potential wonder, as its described as being able to use "thermionic energy conversion" to convert excess heat directly to usable, waste-free energy. Additionally, the uses are "nearly endless," as it could be placed on a laptop's processor to render the Li-ion cell completely unnecessary, or strapped onto a fireplace in order to generate electricity for gizmos around the house.
