  • Start by defining your available power. How many watt-hours can you generate? A small 100W solar panel can provide an average of 400Wh of energy per day in the winter. That’s more than enough to run a 10-inch tablet 24/7 and LED lighting at night. I’ve seen 360W solar panels for under $100 on the used market. That’s a couple of KWh a day. Even a 100W bicycle generator and a 30 minute workout would power a tablet for 8 hours.

    If power consumption is that big of a factor, perhaps separate devices for video, music, and reading would be beneficial. A dedicated music player can consume less than a watt. An e-paper reader requires fractions of a watt.

    I have a folding 100W panel, a 30Ah 12V LiFePO4 battery, and a charge controller that I use while car camping. It keeps all the electronics running for a group of 4 without relying on a noisy generator. The battery is big enough to compensate for a couple of rainy days.

    My backpacking setup is a 15W panel and a 30Wh battery. That kept my phone and flashlight charged for 2 weeks on the Pacific Crest Trail.






  • I would 100% patronize a restaurant that had full transparency and decent no-frills food. They publicly post all their expenses and how much profit they make. Charge a table/dine-out fee, then actual cost of food and prep on top. Pay their workers in full, so no tipping required. Explain things like dining hours that help the business keep down costs.




  • I use the knife a lot, mostly for opening the bag of pellets for the pellet stove and opening Amazon boxes. Yesterday I was using my chainsaw about 1/8 mile from the house. The chain slipped off the drive sprocket. Out came the Leatherman and the pliers pulled the chain back into place. Saved me at least 10 minutes not driving back to the house for the tools.

    Last week a little kid had a birthday party at the park. He got a remote control car, but nobody in his party had a screwdriver to open the battery compartment. I was at a nearby table and heard his predicament. Leatherman to the rescue!

    A few years ago I stepped on a nail while hiking. It went through the sole of my shoe and into my foot, pinning it inside. The Leatherman let me pull out the nail so I could remove the shoe and tend to the wound. It would have really sucked hobbling 4 miles with a nail in my foot!

    My buddy also wears a Leatherman. Before cell phones became common, he was walking alone on a steep hillside when he slipped and tumbled over a retaining wall that was under construction. He ended up suspended from the wall by a spike of rebar through his arm. He used the metal saw to cut the rebar. He credits the tool with saving his life, because who knows how long it would have been before someone else came along.


  • Not really a game, but playing Minecraft has made me wish for real-world modeling software with a similar first person interface. Select from standard off-the-shelf components, use real-world tools, and craft stuff. Then test it out. I’ve got ideas in my head for all kinds of stuff, but going from there to an actual model is tedious with standard CAD and modeling software. Why can’t I (virtually) take an 8’ Douglas Fir 2x4, cut it with a saw, drill some holes in it - you get the idea. I could make something like a shed, then stress test it in a windstorm, pile 4 feet of snow on it, or drench it with rain. Or build a go-kart and see how it would perform. Tweak the design until it does what you want. Make the app user moldable and let the community go wild adding capabilities and virtual materials. Maybe it could eventually generate real parts lists, fabrication data for 3D printers and CNC machines, and assembly drawings.


  • So which city are we going to tear down and rebuild first? And we have to come up with some new laws, like you can only own a home that’s within walking/biking distance of your work.

    We had a taste of a viable alternative, thanks to the pandemic. Remote work - it accomplishes most of what you propose without totally ditching private transportation. Maybe we should make that a law - business has to show that physical presence is required or they must allow employees to work remotely.



  • Two “gadgets” that I’m never without. My Leatherman multitool and my RovyVon Aurora flashlight. The multitool with locking blades is like carrying a toolbox on your hip. And that flashlight - it’s 2 inches long and 1/2 inch wide, but it can kick out a beam that lights up things 1000 feet away. Or provide enough light to read by for 40 hours. Yeah, I can use the smartphone’s flash, but it isn’t bright enough to show me if the two eyes reflecting back at me belong to a dog or a bear. That’s important where I live.
