EEStor Issued a Patent For Its Supercapacitor

An anonymous reader sends us to GM-volt.com, an electric vehicle enthusiast blog, for the news that last week EEStor was granted a US patent for their electric-energy storage unit, of which no one outside the company (no one who is talking, anyway) has seen so much as a working prototype. We've discussed the company on a number of occasions. The patent (PDF) is a highly information-rich document that offers remarkable insight into the device. EEStor notes "the present invention provides a unique lightweight electric-energy storage unit that has the capability to store ultrahigh amounts of energy." "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 lithium-ion cells, the technology is said not to degrade with cycling and thus has a functionally unlimited lifetime. It is mentioned the device cannot explode when being charge or impacted and is thus safe for vehicles."

My computer NEVER stops working. If I'm not gaming, I'm encoding. If I'm not encoding, I'm compiling or recording. If I'm not using it and am asleep, it's protein folding at maximum possible speed.

Kill-a-watt says 550-600 at full load, and that's just testing the computer, not monitor or other peripherals.

You also forgot to add in my other equipment which consumes power at the same rate, idle or not. Speakers excepted, they draw 40 watts idle with no sound going through them.

My power strip is at load at 1500W rating. Putting on a 60 watt light trips it out.
