Behind The Scenes in 2025, A Lesson In The Reality of Solar: Running TWO Freezers Off The Electrical Grid
The Reality of Solar is a term I started using years ago in some of my earliest videos on YouTube. As a scientist at heart, I’ve always been curious about the true nature of reality. I don’t care for armchair expertise (not to mention the opinions of armchair experts). No I want true real-world hands-on…

PV2L-MG: My Low Voltage DC Residential Micro Grid Goes Live! Direct Solar Photovoltaic
It’s live! After several years of testing and research, then a long and grueling move to the countryside, I installed the first Low Voltage DC wall outlets in my house. A full length multi-episode video documentary is in production to document the system. Within hours these outlets were powering up one of my DC cooktops,…

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…

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…

Boiling Water with 14w of Solar Powered Induction (plus video) EXPERIMENTAL
It’s that time again… another solar powered experiment at the outer edges of “feasibility”. Part of my work and research in solar power the past few years has been about finding ways to do “more with less“. Often I try to accomplish a task using only the solar panel itself, using minimal to no electronics…

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…

24 Volt car radiator fan, 50 watt solar panel – A Perfect Match for Solar Shed Ventilation?
Are 24 volt car radiator fans a good option for solar shed ventilation? Sheds tend to get very hot in the summer, and my two sheds are no exception. For the past several years, I’ve been using simple configurations of solar panels connected to fairly powerful DC fans to cool them off. This video shows…

Solar Air Conditioning – Direct PV DC – Project Updates and Video
Note: ongoing project updates will be posted towards the end of this page. Thinking in terms of a grid-down scenario, besides food, water and shelter, air conditioning is one of the most important modern benefits to society. There is nothing that can boost morale like a good cold AC and a place to rest after…

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…

DIY Bus Bars for lithium-ion cells – handmade in the workshop
Recently I needed some copper bus bars for a lithium-ion pack I was building. This pack will be used to power a prototype cooking appliance. But I did not want to buy any pre-made bus bars and decided to try the DIY option. There is also a video documenting this technique posted down below. First…

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…

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…

Nichrome and fuses melting at 1800x magnification – video
Recently I was asked by Joyalens to review their JL246MS digital microscope. I accepted in order to look at Nichrome and fuses up close. (Note I don’t receive any commissions for sales). Interestingly this microscope is USB 5v powered, so it’s easy to run even off of a battery pack if needed. Nichrome wire forms…
