Statement of Purpose and Hypothesis:rnPurpose: Is it possible to create perpetual light?rnHypothesis: I think I will be able to create a way to have light, that once connected to a battery, will be able to power and repower itself in a perpetual cycle. I will use a solar panel and the laws of reflection of light to recharge the battery and continue the cycle.rnrnMethodology:rnI experimented and documented, in a journal, my methods that lead me towards creating a perpetual light machine and the adaptations I made to my product throughout the process. My final product was a cube that had 5 of the 6 walls covered in mirrors. These mirrors reflected the light emitted from the bulb which was powered by a rechargeable battery. The reflected light was directed at a solar panel which converts light into electricity. The electricity produced was used to charge another battery. Once the battery powering the bulb ran out of energy, the battery charged by the solar panels was switched with the dead battery. Theoretically, this process continues in a cycle therefor creating perpetual light but practically no man made machine is efficient enough to be perpetual.rnrnAnalysis:rnMy table shows the evolution of the design of the machine in regards to the materials I used. I recorded the different light bulbs used and the time before they broke and also the different types of batteries used. The data I collected told me what would be the best materials to use for the building of my final product. rnrnSummary and conclusion:rnThe results produced from my machine were that once the battery powering the light ran out of energy and was switched with the newly charged battery, the newly charged battery had enough energy stored in it to power the light for only 30 seconds after being charged by the machine for 30 minutes. Thus I rejected my Hypothesis because the over all efficiency of the materials made perpetual light is impossible. My machine did not work because all of the supplies are man made and are not 100% efficient. One of the main material that decreased efficiency was the solar panel which had an approximate 25% efficiency rating, meaning only 25% of the light energy going into the solar panel is being converted into electrical energy. I concluded that perpetual light is not possible though reducing electricity use in this way is possible.rnrnrnApplication:rnIf my invention had worked, or had been more efficient, I could have reduced the amount of electricity used in buildings. That would not only reduce electricity costs but also energy consumption. Though perpetual light is not possible, what I have done is an improvement towards lowering costs and lessening the energy and environmental crises we face.
