| Well.. Well. Well... It looks like our EEStor friends have a new patent. EEStor Inc. (the secretive little company in Cedar Park Texas) was issued a new patent. for their lightweight highly energy dense electric storage unit (EESU). Currenlty, no protoype is known to exist. The core ingredient is an aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix. The EESU is composed of 31,353 of these components arranged in parallel. It is said to have a total capacitance of 30.693 F and can hold 52.220 kWh of energy. The device is said to have a weight of 281.56 pound including the box and all hardware. Unlike normal lithium-ion cells, the technology is said not to degrade with cycling and thus has a functionally unlimited lifetime. http://www.ultracapacitors.org/index.php?option=com_content&Itemid=68&id=154&task=view  |
