Then the peak power needs come from the capacitor rather than the grid. Power bought from the grid can be essentially constant. While this can be done with batteries the short life time low efficiency and long recharge cycles limits their usefulness. Now if there is a power outage in a community, every house with a capacitor can continue to operate at or near normal consumption levels. When the power is back on, charging must be metered to avoid overloading the grid. <BR/><BR/>In a car a capacitor could be charged at say 3kV on the road in just a few minutes. At home, charging would be at 120 or 240 volts overnight. High rate charging at home would be accomplished by hooking the car to a 3kV capacitor that has already been charged overnight. Just transfer the charge from one to the other. With the internal inverter the car can be slow charaged when at a motel or any location with 120 v power on hand. <BR/><BR/>Individual appliances of all kinds can use this concept. Already there is at least one electric tool (Coleman screwdriver) that is charged in 90 seconds. Virtually any tool now operated by a gas engine could be powered by a capacitor/motor combination that can deliver the high torque needed for power tool applications.<BR/><BR/>Keep a small supercapacitor in the car as a reserve against a low main battery.<BR/><BR/>I still have reservations about the safety of the device. It can contain considerable energy. If fully charged and then shorted (say, crushed) during an accident of some kind, there could be an explosion the equivalent of a tank of gasoline blowing up. Most gas tanks have special construction techniques to reduce this problem.<BR/><BR/>This is an invention of considerable importance and worthy of highest priority by industry and government.<BR/><BR/>BC EngineerAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9560953.post-60092604151811589462008-03-30T21:45:00.000-04:002008-03-30T21:45:00.000-04:00yes Adam you got the math rightyes Adam you got the math rightUnknownhttps://www.blogger.com/profile/17557031241918722413noreply@blogger.comtag:blogger.com,1999:blog-9560953.post-58983698674608899372008-03-29T16:38:00.000-04:002008-03-29T16:38:00.000-04:00I dunno if it's still accurate, but their claims w...I dunno if it's still accurate, but their claims were $3,200 per 52kWh unit for the initial production, falling to about $2,100 with mass production. <BR/><BR/>That puts the cost of 770 units at $2.5 million at the inital price, or about $1.6 million at the mass production price. So with the $5 million for the wind turbine, that's a total of $7.5/$6.6 million.Anonymousnoreply@blogger.com
