Keeping your electronic gear powered up while you’re in the field is always a challenge, especially if you’re shooting some of the fantastic adventure films that we’ve seen in recent years. Fortunately, solar power has come a long way, and is now a viable option for any expedition. Goal Zero is one of the companies that has led the way in this category, and the video below gives you an idea of what their products are capable of. While this is a promo video of sorts, it also features some amazing shots of some of our favorite outdoor athletes in the field as they are being filmed for the upcoming Reel Rock Tour. It also gives us a glimpse of how these filmmakers work in the field. Very interesting stuff all around.
