Testing a 50 year old mercury arc rectifier A mercury-arc rectifier is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC). It is a type of cold cathode gas-filled tube, but is unusual in that the cathode, instead of being solid, is made from a pool of liquid mercury and is therefore self-restoring. As a result, mercury-arc valves were much more rugged and long-lasting, and could carry much higher currents than most other types of gas discharge tube.
Rescuing a Bumble Bee Occurred on March 22, 2018 / Bishops Stortford, Hertfordshire, England I was riding a horse for my Friend Sandie. When we had finished we noticed her chap Leaf that helps her with the garden holding a bumble bee. Sandie went and got some warm sugary water and fed it. Leaf then went to put the bee under some shelter. It was a cold wet blustery day although the sun had been out. The bees were coming out but they had no energy. Or warmth from the sun . So it was lovely to be able to help one .

Timber A group of logs is about to freeze to death in a cold, icy desert. When they realize that the only fuel for a warming fire is their own body, things start heating up.
Diana Bastet Metal Bellydance. Sepultura “Ratamahatta” Cold night, hot fire, mystic place and my dark insanity.
We did it:)
I wanted to make a video to this song two years already, but I didn't had an opportunity - cause it's can't be a simple movie somewhere indoors. No...I needed only darkness, forest and fire, I needed real thrash metal insane dancing. And here is it:)
I danced to this song at festivas and parties and finaly I can share a video with you.
Special thanks for making this video to amazing camerawoman Jane Diden. She did a great job, she catched every my movement with camera at that cold night and made this video.
Music: Sepultura "Ratamahatta",album "Roots", 1996.
Rescue a dog in a frozen lake Harlem-Roscoe firefighters were dispatched to a call on the Legends Lake in Roscoe for a man on the ice trying to rescue his dog that had fallen through thin ice into the lake on Dec. 11, 2017. It seems the dog's owner found his dog in the water and tried using a kayak on the ice to get to him. About half way out he broke through the ice himself and was now in the water. First in units arrived on scene and Lt. Justin Mayton donned a cold water suit and firefighters secured him to a safety rope. He then headed out onto the ice with a second Kayak that was on scene. He reached the owner of the dog and the dog's owner was able to climb into the kayak. Mayton was then able to reach the dog and he and the dog were pulled back to the shore by the firefighters on the shore. A rope was also then thrown to the owner in the Kayak and he was pulled safely to the shore. The dog and the owner were warmed up in the ambulance and taken home.

Primitive Technology: Natural Draft Furnace I built a natural draft furnace to test ideas about how hot a furnace could get without the use of bellows. Natural draft is the flow of air through a furnace due to rising hot air. The hot gasses in the fuel bed are more buoyant than the cold air outside the furnace causing them to rise. Fresh combustion air then enters the base of the furnace to replace the rising combustion gasses, keeping the fuel bed burning. This effect increases with: 1. the average temperature of the fuel bed relative to the outside air and 2. The height of the furnace. Two other important factors are the size of the tuyere (air entry pipe) and lump size of the fuel bed as these effect the resistance to airflow through the furnace. The furnace was tested with wood fuel and some ore was melted but produced no iron. High temperature were indeed produced (probably about 1200 c). These types of furnaces were once used for smelting copper and iron ores in around the world in ancient times, usually using charcoal as a fuel and in some cases wood too.
