Biochar is made from organic material known as biomass. Biomass is mostly made from carbon. Carbon in biomass is captured from carbon dioxide in the air by plants. This means that when biochar is made carbon that was once in the air is made into a solid material. Biochar can last a very long time in soil and even longer in containers.
Some people propose making biochar to remove carbon dioxide from the atmosphere.<ref name="DOI10.1038/ncomms1053">
</ref> Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change. If a lot of biochar were made then there would be less carbon dioxide in the air, meaning less heat would be trapped. This is known as a carbon sink, because the carbon is sunk or put into a long lasting material instead of floating in the air.
When biochar is made the biomass it is made from has most of its material removed. This means that biochar is very light and filled with tiny holes. These holes can hold water and nutrients which act as food for plants growing in biochar. Biochar can be soaked in nutrients to "charge" it which makes it a very good soil additive or fertilizer. The holes in biochar can also trap toxins which make water unsafe.
Biochar was used by people in the Amazon to make their poor quality soil better for growing food. This made the soil very dark and the dark soil can still be seen today.
In some rainforest places the forests are cleared for farming. When the forests are cleared they are usually cut down and burned. This process is called slash-and-burn and doesn't leave very many nutrients in the soil. If the forests were cleared and turned into biochar rather than burned the soil would have more nutrients. This is known as slash-and-char and would make the soil better for farming.
Biochar can be mixed with molasses for use as animal food. The biochar helps digestion and reduces the amount of methane produced by cows. Feces from animals that eat biochar is a high quality fertilizer.
Biochar is mainly sold by fertilizer companies to people who grow plants. This may change. There are many tons of carbon dioxide in the atmosphere which is causing climate change. Many countries have agreed that this is a problem. In the future it may cost money to release carbon dioxide. If people who remove carbon dioxide are paid then there could be businesses which remove carbon dioxide for money. One way a business like that could remove carbon dioxide is by growing plants and turning them into biochar. This removes a large amount of carbon dioxide and could be very profitable in the future.

Bab Mansour
Bab Mansour Gate (also known as Bab Mansour Laleuj) is the main gate of the Old Town of Meknes in Morocco. It is one of the largest and most impressive gates in the country. Together with the "outer square (El Hedim Square)", it is considered the country's business card. The gate is located in front of El Hedim Square which is considered to be the most popular square in Morocco.
The gate structure was completed in 1732 by Mulay Abdullah who was the son of Sultan Mulay Ismail. The gate marks the main entrance of the imperial palace built for Isla Mulay and the ancient city of Meknes.
The door was designed by a Christian who converted to Islam whose name was "Mansur". Hence the gate's name: "Mansur Gate". The gate structure has been part of the Meknes protected heritage since 1914 and since 1996 has been used as a World Heritage Site along with the Old Town of Meknes.
The gate structure separates the outer square called Al-Hadim Square. It is adjacent to the Old City wall of Meknes, from the inner square called Lela Awda Square. It served as the "Royal Order Ground". Next to the gate within the walls are the Royal Order Stables, the Royal Prison, and the Meknes City Museum. It is decorated with green ceramics designed with Islamic motifs. The white pillars are columns that used to stand in the Roman city: "Volibilis", which is about 30 km north of the city.

The RL Sport (RLS) was a light car that was a foot shorter, so it saved weight. It also had a bigger engine. They made around 500 of these. It changed name to RL Super Sport (RLSS) and 22/90, and was even faster.
This was even shorter than the RL Short and won the Targa Florio race on Sicilia in 1923. They called it RL Targa Florio (RLTF) and less than 10 were made.
