It’s tough to pinpoint just when we started harnessing the power of fire. The reasons this is so challenging are many. For one thing, we do know it happened a long time ago. Close to a million years. Also, we weren’t exactly “human” as we’d recognize today. Our best guess for the first user of fire is Homo Erectus, one of the first of our ancestors to walk upright. We’re not sure if they knew how to make fire though, or just capture and control naturally occurring blazes.
But enough science talk. As far as we’ve come in the past million or so years, we still rely on fire. Everything from electricity to the cars we drive relies on combustion of some kind. But simpler still, fire is essential the world over in providing heat and cooked food. This clever invention, known as a Swedish fire log, would have been adored by our caveman ancestors. It is super-efficient, burns for ages, is weather resistant, and if you cut the log level, even offers a handy way to cook a meal in the great outdoors. All with a single log.
