When I was 12 my brother his friend mother and I were hanging out and we saw smoke so my mom asked if I want to pull the alarm. How was it that my mom asked me as opposed to my brother and friend. We were outside and she gave me instruction on how to do the alarm. What do you think my brother and his friend thought when I was pulling the alarm? My mom could have pulled it herself but i guess she was cool and wanted me to do it because I said do you need help? any ideas
Thin films are material layers of about 1 ?m thickness. The main applications are electronic semiconductor devices (thin film transistor), optical coatings (anti-reflective coatings on glasses, reflective baffles on car headlights, and for high precision optical filters and mirrors), ferromagnetic thin films (in computer memory), ceramic thin films (protection of substrate materials against corrosion, oxidation and wear). Thin-film modules are expected to be cheaper to manufacture owing to their reduced material costs, energy costs, handling costs and capital costs. However, thin films have had to be developed using new semiconductor materials, including amorphous silicon, copper indium diselenide, cadmium telluride and film crystalline silicon. In all cases, these technologies face major technical and financial hurdles.
It is possible for this to happen, but the generated electricity only occurs seldom, and the energy you could generate might destroy your generator (since it is so large). Also, the reason that the lightning rod works, is that it provides the path of least resistance to the ground for the lightning electricity to travel. IF you were to insert capacitors/inductors/generators, you would create an impedance (effectively resistance), which would discourage the lightning from traveling through it. Now, the lightning is just as likely to travel through a nearby tree, since you've obstructed it. In the water analogy, if you have one open-smooth stream, and one stream of rocky rapids in parallel. More of the water travels through the open-smooth stream. However, if you insert paddle-wheels which are busy milling grain, then less water travels through this stream and more water travels though the rocky rapids.
