Hi everyone. First let me thank the maker and Contributers to this website articles and forums, they are a great help to people like myself. Im into my bushcraft and survival activities even thoe again Im learning more in this area, topics like "off the grid living" and self sufficient lifestyle. I like the idea of living "off the grid" not totally but its good to have a option to reduce our dependance on the electricity grid, I like to be self sufficient in food and other things, im not against all technology and things we use but im wondering if electricity disappeared tomorrow what devices could we use and how can our electronic hobby come into play to help us survive? If you get what im saying, when we think of electronics people assume televisions and plastations and ipod. I know electronics is more than that like the medical field and space exploration, wind up radio and torch lights. But I dont know if you know ways we can use what we know to help in a survival situation where we need water, shelter, food and communicate and generate power? I seen one video someone that build power batteries and a generator from wind/sun solar to his home, surley they is more than only this idea and where do the circuit boards, components and stuff come into play here?
