  • While the future of our environment, national safety and political discourse is in disarray, there is at least some good news to celebrate overseas. The results of the UK snap election that Theresa May hoped would shore up support for her Conservative party backfired when they actually lost seats in Parliament. And in Germany, citizens are getting 85 percent of their electricity from renewables like wind and solar power, a feat our nation has yet to accomplish when our current Commander-in-Chief thinks the the only thing that should be solar powered is the surface of his skin. Lee Camp covers the good news abroad and more in the latest Redacted Tonight.

    I made a video last year about charging my boosted board from my Yeti 400 solar generator. This is a SUCCESSFUL re-engineering of that system, designed to get size and weight down to a level that can be comfortably transported via a backpack.

    Here’s Part 1 showing assembly process: https://youtu.be/vAMekgM32Z4

    Here’s Part 3, all about folding solar panels: https://youtu.be/aFuZlnsunKg

    Here’s the original Yeti 400 video that started this project: https://youtu.be/VlaHBB3GRwg

    Get your own boosted board today!

    Here’s the power meter used in the video:

    These are similar to the panels used in the video (solar panels go in and out of stock quickly, so these may not be the exact brand in the video, but they’re equivalent):
