Writer Paul Salopek is on a seven year walk “starting at humankind’s birthplace in Ethiopia and ending at the southern tip of South America, where our forebears ran out of horizon.”
He is using PowerFilm solar panels connected to our V60 (now the V88) to keep his electronics charged. Says Paul, “the direct DC feed from the solar camel’s two PowerFilm panels–I have acquired two now, a 20W panel and a 30W panel–charges up the battery within about 4 hours and gives me up to eight or nine hours of extra work time on my most energy-hungry piece of equipment, my MacBook Air. ”
Prior to his trip, Richard Smith calculated Paul’s daily power needs and published them in this blog post (it is also an excellent guide to anyone who is interested in fully powering their gear on an expedition). Here’s an excerpt:
