Hey, I just had a tech idea for missionaries. I just ran across something interesting on Amazon- it is pages and pages of solar batteries and power banks. They will charge in the sunlight and charge an internal battery. The little ones can charge a cell phone while the big ones can power a laptop or even video and audio equipment to show a movie, these would be just the ticket if you are doing missionary work in a rural area. I know some missionaries that go into remote villages like to play the Jesus film and then invite people to give their lives to Christ, one of these could easily power the projection equipment and being solar you have unlimited access to power and don't need to haul around a gas generator. These come in all sizes on Amazon and range in price from $40 to $2500, they are slick! The link to the website is here:
