Problem Statement : resistance ...circuit breaker's opportunity : innovative capcitors , fuse made of tungstun .... given the dual advantage's ....it can function like a bulb , as also a capacitor. further to as envisaged and published by this individual on this uri/url. a combined component derived out of tungstun used in micro-electronics viz. electronic circuitry i.e. PCB ...etc, offer a potential opportunity. thus ...aptly placed or housed a fuse/capacitor can properly illuminate the enclosure's of a gadget's like refridgerator , air-cooler , air-conditioner. Note: The above problem statement having been encountered in various scenarios and detailed in various 'Proof of concepts' as mentioned in http://uk.geocities.com/ravivenkatus/projects.pdf http://ravishankarkv.tripod.com/projects.pdf ....apply appropriate 'use-case' modeling, rationalize and arrive at a workable and feasible solution both commercially and techinically viable.
