This device plus a collecting antenna supposedly powered an electric engine that powered an automobile. Anyone got any idea where that research went?kenhttp://www.blogger.com/profile/03491985556618859390noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-54550701969041081362008-09-20T07:35:00.000-07:002008-09-20T07:35:00.000-07:00ultimate idea man . it will be very nice . what we r doing in power plant is like only 30% efficiency. with Theft &amp; Decoit loss of 30 % we r getting 20% efficiency. it will be ultimate idea if we burn any fuel and convert the energy coming directly in to electricity. so welcome to the future ...........<BR/>now no more neutonion physics...all is nano physicsfun workshophttp://www.blogger.com/profile/14366684334203529638noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-47615206314762052542008-09-05T02:06:00.000-07:002008-09-05T02:06:00.000-07:00In addition to what graal said about cars - 18% of the energy is used carrying the car and engine around. 2% is used to carry the person(s).- Dieterhttp://www.blogger.com/profile/00877580713715517545noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-39861346684298464612008-03-28T21:24:00.000-07:002008-03-28T21:24:00.000-07:00Excellent news, Brian, though I do wonder how much flux such a collector can stand and what cooling it might need for long-term operation. Of course if it can be used for drawing power from Pu-238's emissions, then it has amazing potential for powering deep-space probes. <BR/><BR/>Ever since I read "Foundation" I've always wanted a nuclear battery I can wear on a belt - now all I need is a personal force-field generator ;-)<BR/><BR/>Cars, in normal driving conditions, use about 6.5 kW of power directly (about 60% is lost due to thermal inefficiency, and 20% as frictional heating in the drive-train), so by my BOTE calculations a ~ 15 kg nuclear battery could provide power for an electric car.qraalhttp://www.blogger.com/profile/13436948899560519608noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-43111395806832362292008-03-28T02:42:00.000-07:002008-03-28T02:42:00.000-07:00Like Joffan said, plus I would include high efficiency thermoelectrics to covert even more of the output into electricity.Sigmanoreply@blogger.comtag:blogger.com,1999:blog-17555522.post-54891090163161337982008-03-27T16:58:00.000-07:002008-03-27T16:58:00.000-07:00I always liked the idea of direct transition of radioactivity into electricity, which has dodged practical implementation several times that I recall. If it finally becomes feasible, I wonder whether the nuclear power stations could use it for either <BR/>(a) main power generation (I'm thinking probably not, too hostile in the reactor) or <BR/>(b) drop used fuel into a radiation convertor (no neutron flux -> less challenging materials environment), for auxiliary power gen.<BR/>Second option might well be ideal for CANDU with their continuous refuelling process, so having a pretty constant age/radiation profile on the used fuel.Joffanhttp://www.blogger.com/profile/18025437863119781181noreply@blogger.comtag:blogger.com,1999:blog-17555522.post-2993139294579865592008-03-27T13:26:00.000-07:002008-03-27T13:26:00.000-07:00coolJonathanhttp://www.blogger.com/profile/18026476004883859119noreply@blogger.com
