Don’t Have Matches? I Started A Fire With A Lithium Ion Solar Generator – Was Just Curious!
High Tech Survival In this high-tech age, it seems people often lack the most basic survival gear, but yet they have a “smart” phone, wi-fi and many different gadgets. What if they were stranded out in the woods with only a solar generator or portable power station? Could they start a simple campfire to keep…

My Simple Solar Pump! and a gray water recycling project starts
I really love water… and pumps… any excuse to play with them I will take. For years, I have wanted to build a gray (grey) water recycling system. Gray water means from the sink, dishwasher, laundry etc. and not sewage, which must never be discharged without proper treatment – that would cause a major health…

The Most Important Prep For Survival? Water Storage and Purification Alone is not enough…
There is one resource any Survivalist or Preparedness oriented person should be an expert on first and foremost. You must have skills in retrieving, storing and processing it – or all the rest of your preps simply don’t matter! Having the right mindset is still top of the list, yet everything still depends on this…

14 Watts Can Do WHAT? Getting smarter about solar power, efficiency and high-tech survival
Hi folks, most survivalists know how much food & water they need to survive “X days” in the jungle”. That’s because they are smart and take time to think things through! But have you ever wondered, how many slices of toast can that 12-volt 10 amp-hour lithium battery make?? Note: this article is about an…

Mini Peltier Freezer Powered by Solar – solid state refrigeration prototype (plus video)
For the longest time, I’ve been fascinated by those small Peltier based fridges and coolers for sale on the internet. They generally drop the temp to something pretty “cool” but they often fall short of an actual “refrigerator”, let alone freezer. (Video of my test freezer – article continues below) What I’d really like to…

How Many SOLAR Watt-Hours does it take to cook? (Documented Experiment plus Video)
Kitchen-Grade 12 Volt Cooking Appliances are an untapped industry in my opinion. There is a pressing need all over the world for simple, durable and affordable 12v cooking appliances, but most of the ones available are not designed for the rigors of daily use. After years of searching for alternatives, I could not really find…

Insulated Solar Electric Cooker – simple DIY! affordable off the shelf option plus video
An insulated solar electric cooker, sometimes referred to as “ISEC” is an insulated container that takes a direct solar panel input to cook food. These appliances are generally a DIY project and not something available off the shelf. A good example is my small solar electric cooker which I used to boil an egg with…

Pure 12V Off Grid Cooking With a 200AH LiFePo4 Battery! Article and video
A larger 12v lithium ion battery offers a renewable energy source for cooking. In fact, such a good sized battery can replace the fuel tank typically used for cooking in some scenarios. Recently I received a sample of Power Queen’s 200ah deep cycle LiFePo4 battery. I put it to the test by simultaneously operating three…

Pecron E600 LFP – solar generator endurance test and review
A solar generator is a great way for people who are new to solar power to get started without much effort. Just plug in the solar panels and go. Over past years I have collected, purchased and repaired over 40 solar generators and portable power stations of various kinds – definitely enough to experience their…

Building a Solar Powered Ryobi 18v Battery Supercharger x3 – Project Overview plus DIY video
If there’s one thing that has changed DIY over the past few years, it’s cordless lithium ion powered tools. I use a lot of Ryobi 18v batteries to run tools and have become addicted to their flexibility and affordability. But the charger usually is plugged into an AC outlet. Why not simply plug a solar…

Direct Solar Electric Cooking vs. traditional methods – A Grid Down Scenario
It’s happened, The Grid Is Down. Roads are closed. No gas stations are open. Nothing works. Electrical power and communications are gone. Chaos is slowly breaking out. But the Off Gridder feels fairly secure; solar panels on the roof, 20kw of batteries, a wondrous integrated inverter with bluetooth, MPPT charger all crammed into one giant…

My 12 Volt Hotplate Cooktop Prototype – Cooking without an inverter
This project has the goal of the total conversion of a portable kitchen cooktop / hot plate to pure 12 volts DC operation – NO inverter! Second is to show and demonstrate that such an appliance should exist. I believe this type of 12 volt appliance should be common and affordable. With a 12 volt…

20 Watt Solar Panel Boils an Egg! My ultra efficient solar electric cooker prototype (Video Added)
Cooking food with only 10 watts of solar power sounds unattainable – but it’s not. This was recently proved in my solar workshop. I used a combination of an insulated food container with a diode chain solid state heating element to efficiently extract heat from a solar panel. The result is an ultra efficient mini…

Tiny 12V LiFePo4 Lithium Solar Powered Kitchen Setup – Emergency Preparedness Test
Cooking food from smaller solar power systems has always been one of my key interests. High tech survival and emergency preparedness too. But cooking with standard kitchen appliances often seems out of reach due to the high power draw required. And many people do not have large batteries and inverters to do the task. The…

Solar PV Solid-State heating elements (Diode Strings) explained
This post is mainly to address the lack of understanding about solar powered (PV-to-Load) solid-state heating elements – also called a diode string or chain. The Part 2 video presentation and this blog post should help fill in the blanks. The video itself is also posted here on this page. Watching Part 1 is also…
