Introduction to Fuels

[Silence] [Music] The fire environment triangle includes all the things in the environment that influence fire spread and behavior patterns in nature. Fuels, weather, and topography are the primary factors that influence how hot a fire gets and how fast it spreads. In addition, fire is included in the center of the triangle. Fire itself […]

Man Living in a Sustainable & Innovative Earthship Home – Full Tour

>>DANIELLE: Hey everyone in this video, we’re visiting a stunning three-bedroom Earthship home in Ontario, Canada. The house was built with recycled tires. It has a massive 10 kW solar power system.

The Winter Greenhouse, grow in -40’C (2020)

Imagine taking the heat from the sun in the summer, storing it, and then using it to heat a greenhouse in the winter! Heating a greenhouse costs so much in Canada in the winter that it’s cheaper to truck food in from 1000’s of miles away. Trucked in food is chemically ripened and tastes horrible. […]

A small 7kW biogas plant to produce electricity, heat and biomethane – English subtitles

Welcome to Barrett’s Mill in Shropshire. This is the site of the Evergreen Gas pilot-prototype anaerobic digester, small-scale, which we’re using to test a new concept of anaerobic digestion which is below-ground plug-flow digestion compared with continuous stirred-tank reactor and here we’re able to use this site both for experimenting with different types of feedstock […]

Solar Cell Part 1: Heat Transfer Coefficient

Here we have a simplified version of a solar cell and it consists of: down here a very thin silicon layer, and then we have one millimeter thick of adhesive, and glass. The length of this solar cell is 0.5 meters. It’s width is 0.2 meters. It’s on an insulated surface, which means that we’re […]

Solar Cell Part 2: Surface Temperature

Here we have a simplified version of a solar cell, and we have right here our semiconductor silicon layer, on top of that is adhesive, and then we have glass. And what we need to find out is the temperature of the silicon, that we’re going to call T 1, as well as the temperature […]

Chernobyl: How RBMK 1000 works ? (original soviet explanation)

Experience of the first NPPs with channel reactors made it possible to begin the implementation of a program for the extensive construction of NPPs with such reactors in our country. At the Leningrad NPP is installed a high-power channel reactor,abbreviated – RBMK . The electrical capacity of a power unit with such a reactor is […]
