Zane Bridger

Hi, I'm Zane. I'm 15, and I'm the one in the family who likes numbers. My dad says I "turn everything into a spreadsheet." He's not wrong. Last week I calculated the exact solar panel wattage you'd need to run a chest freezer off-grid in Maricopa County based on average daily sun hours by month. For fun. My brothers think I'm weird. I think they're missing out.

I built a weather station in our backyard when I was 11. It tracks temperature, humidity, barometric pressure, wind speed, and rainfall. I log all of it. Every day. I've got over two years of data now, and I can predict afternoon monsoons in our area about 80% of the time just by watching the morning pressure readings. The National Weather Service is right about 84% of the time, so I'm getting close.

My favorite thing in survival is navigation. Maps, compasses, GPS, celestial navigation — I love all of it. There's something satisfying about being able to figure out exactly where you are using nothing but a map, a compass, and some math. Most people rely on their phone for directions. Your phone battery dies in 8-12 hours of heavy use. A compass never runs out of battery. That's just math.

I also write about solar power, water filtration systems, and off-grid technology. These are systems you can actually calculate and optimize. How many gallons of water does your family need per day? (Answer: about 1 gallon per person for drinking, 3-5 gallons total when you include cooking, hygiene, and sanitation.) How many solar panels to go fully off-grid? It depends on your latitude, panel efficiency, battery bank capacity, and daily consumption — and I'll show you exactly how to calculate all of it.

I know I get a little too deep into the details sometimes. My mom tells me to "get to the point" and my dad says to "save some for the next article." But I think the details matter. If you're building a water filtration system, you should know the micron rating of your filter, the flow rate, and how many gallons it handles before replacement. That's not being nerdy. That's being prepared.

My articles have data tables, calculations, and technical breakdowns. If that sounds boring to you, Boone's articles are shorter. But if you want to actually understand how this stuff works — the math, the science, the systems — I'm your guy.
