A crystal radio is a radio that only uses the energy of the radio waves themselves, picked up by the antenna, to generate the sound heard in the head phones. It needs no external power source! It gets its name from its vital component; a crystalline semiconductor component that detects the radio waves.

Crystal radios can be constructed with inexpensive materials, perhaps even already ‘around the house’ and are regarded as the most simple form of radio receiver. This video shows how to make a crystal radio made almost entirely from found items except for the diode and the earpiece.

Did you know that crystal radios were the first wireless devices? At the beginning of the 20th century, an American researcher with the splendid name of Greenleaf Whittier Pickard, discovered that certain natural crystalline minerals could be used to pick up radio signals. The crystal was fixed into a brass holder and the radio operator touched a very fine wire, known as a cat’s whisker, to various points on the crystal’s surface in order to detect the strongest signal.

Crystal radios are distinct from ordinary radios as they don’t have a source of electricity power such as a battery or the mains power to amplify the weak radio signal to make it louder. In other words, there are no batteries, no transistors or amplifiers of any kind and the sounds are produced solely by the energy of the filtered radio wave! The downside of crystal radios is that the sounds generated from them are less powerful and they have a limited range of operation, only being able to pick up transmissions within that range. They typically receive AM signals although FM and even shortwave sets may be possible.

Crystal radios are considered a survival tool. If a grid down situation occurs or in a very remote area, there will be no electricity supply, so building a radio that doesn’t rely on batteries or power could give you an advantage. Surely, there will be some people who will use the airwaves to keep people in the loop and may be able to offer help.

Ok, here’s the video:

This Crazy Off Grid Device Literally Makes Drinkable Water From Fresh Air:

According to NASA, the U.S. is expecting a 100-YEAR LONG MEGADROUGHT.

It's already begun. Ask the farmers in California. They know.

Every survivalist knows that water is of critical importance. You NEED an independent water source that you can count on!

As an interesting "survival rehearsal" - imagine that you turned the tap on right now and nothing came out. How long would you last?

But what if there was another water source literally hidden in plain sight. That's right, I'm talking about the atmosphere!

The amazing thing about getting water from the natural moisture in the air... is that it is ALWAYS available.

This gives you real water security!

😳 What Tinnitus Does To Your Brain Cells (And How To Stop It)

After 47 years of studies and countless brain scans done on more than 2,400 tinnitus patients, scientists at the MIT Institute found that in a shocking 96% of cases, tinnitus was actually shrinking their brain cells.

As it turns out, tinnitus and brain health are strongly linked.

Even more interesting: The reason why top army officials are not deaf after decades of hearing machine guns, bombs going off and helicopter noises…

Is because they are using something called "the wire method", a simple protocol inspired by a classified surgery on deaf people from the 1950s...

Most People Don't Have The Guts To Try This:

An amazing discovery in an abandoned house in Austin, Texas: A lost book of amazing survival knowledge, believed to have been long vanished to history, has been found in a dusty drawer in the house which belonged to a guy named Claude Davis.

Remember... back in those days, there was no electricity... no refrigerators... no law enforcement... and certainly no grocery store or supermarkets... Some of these exceptional skills are hundreds of years of old and they were learned the hard way by the early pioneers.

We've lost to history so much survival knowledge that we've become clueless compared to what our great grandfathers did or built on a daily basis to sustain their families.

Neighbors said that for the last couple of years Claude has tried to unearth and learn the forgotten ways of our great-grandparents and claimed to have found a secret of gargantuan proportions. A secret that he is about to reveal together with 3 old teachings that will change everything you think you know about preparedness:

What REALLY Happens When You Bury a Shipping Container? (Hint: It's A Bit Crazy...)

Shipping containers are all the rage - but if you are thinking about buying one, you MUST watch this video first:

Do not, I repeat do NOT do what these lunatics did! Can you spot the "fatal mistake" they made?

There's a general belief that if you bury a shipping container you can create an awesome root cellar / storm shelter / survival bunker.

But is a shipping container strong enough to handle the pressure?

I Can't Help Showing This Off:

If you haven't heard of Claude Davis yet do yourself a huge favor and watch this video.

One of the smartest guys I ever had the pleasure of meeting, Claude set-up a unique prepping system that changed his life forever.

I already tried it myself and let me tell... you I was completely blown away... His surprising tactics could make your life easier and give you the peace of mind you deserve.
