Folldal Gruver, Norway
This is a video I made from various snippets filmed during a visit to Folldal Gruver, the now defunct mines in Folldal in Hedmark in central Norway. There are outside views as well as footage from the mine museum, the temporary exhibition on the history of the labor movement in Folldal, the café and the National Park Museum. We also visited the mine itself - I made a separate video of that, so check out my channel. :-)

Engraved Gun Taken From Dead Nazi SS Officer | Buchenwald Camp | WW2 Walther PP | Walk-in Wednesday
In another Walk-in Wednesday episode, Tom tells us the story of how he acquired an engraved Walther PP from a dead SS officer in Buchenwald Concentration Camp. This is the story of Lt. Col. Tedford Blaisdell.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine. The main elements common to all gas turbine engines are:
An upstream rotating gas compressor;
A combustor;
A downstream turbine on the same shaft as the compressor.A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into mechanical or electric form (on turboshafts and electric generators), or to achieve greater thrust-to-weight ratio (on afterburning engines).
The basic operation of the gas turbine is a Brayton cycle with air as the working fluid. Atmospheric air flows through the compressor that brings it to higher pressure. Energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The turbine shaft work is used to drive the compressor; the energy that is not used for compressing the working fluid comes out in the exhaust gases that can be used to do external work, such as directly producing thrust in a turbojet engine, or rotating a second, independent turbine (known as a power turbine) which can be connected to a fan, propeller, or electrical generator. The purpose of the gas turbine determines the design so that the most desirable split of energy between the thrust and the shaft work is achieved. The fourth step of the Brayton cycle (cooling of the working fluid) is omitted, as gas turbines are open systems that do not use the same air again.
Gas turbines are used to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and tanks.
