Solar Food Dehydrator

Hi Everyone, Today I’m going to show how I built this solar food dehydrator. First we’ll start with making the base. The entire frame is made with 2 by 3 by 12 foot pieces which minimizes the scrap. The final base size is 36″ wide by 48″ deep. Depending on the width of the glazing, […]

Why Palm Oil Is So Cheap

Palm oil is cheap and ubiquitous. It’s used in thousands of everyday products and is the most widely consumed vegetable oil on the planet. You can get a kilo of palm oil for just $2. But its usage has become unsurprisingly controversial, as huge areas of rainforest have been cut down or burned to make […]

Could This Superfood Save The World?

We have a constantly growing population. This means we will need 50% to 70% more food by 2050. So where are we going to find 50% to 70% more food in only 30 years? Nature is already building and sustaining all life on Earth. We don’t have to reinvent the wheel, the calories we need […]

Kimbal Musk’s Farm of the Future (Yes, Elon’s brother)

Almost always, the fresh fruits and vegetables that we find at the grocery store have been trucked or shipped in from somewhere else, especially if you live in a city like New York like I do, and all this traveling affects the nutrients in them meaning they’re not as good for you as they should […]

Why Don’t We Have Functional Biofuel Yet?

Over the last several decades, we’ve poured billions of dollars into biofuel research…so why can’t you fill up with it at the gas station yet? Where are the biofuels?! After all, the gas you put in your car is essentially an ancient biofuel: it used to be organic matter—mostly algae, actually—that over millions of years […]

And it’s an off-grid house. We live on solar panels, and rainwater, and with a composting toilet. […]

Can I Harvest Hydro-Energy and Still Slow and Pacify Water?

With so much of our water handling attempting to slow and to calm water, is this counter productive, if we are installing devices to harvest energy from water? Well, we have a principle to stop, spread and soak water and that water is then moving through the system slowly. So, it’s much easier to store […]

Future Cities

Welcome to This time, I’m going to talk about future cities. A modern city can be thought of as gigantic creature that depends on resources fed to it from around the planet. However, in the future, such global supplies cannot be guaranteed. Cities have evolved into sophisticated cybernetic machines for keeping civilization alive. In […]

Using Nuclear Science in Food Irradiation

Electromagnetic radiation covers a broad spectrum of wavelengths and includes sunlight, which is vital to life on earth. The waves have different uses according to their energy: radio waves enable us to communicate and share information microwaves cook our food; infrared radiation warms us; visible light illuminates our lives and is essential for food production; […]
