Buses run on fuel cafe

A British startup has joined Shell and Argent Energy to create a biofuel from coffee, used in Lon Don diesel buses.

The company has produced 6,000 liters of coffee oil for the pilot project, enough for a city bus to run for a year. Arthur Kay, bio-bean startup founder, said this is a great example of what can be done when re-imagining waste as an untapped resource.

Startup collects coffee grounds from coffee shops, restaurants, factories and then transfers to recycling facilities. Here, the pulp is dried / dried before extracting coffee oil. Then, coffee oil is mixed with other fuels to produce B20 biofuel, which can be used in diesel buses without modification.

On the website, the company writes: Energy-rich coffee residues, which contain many valuable compounds, turn them into an ideal source for producing clean fuels. Bio-bean estimates that Britons discharge 500,000 coffee pints each year, most of them are discharged into landfills, causing toxic greenhouse effects.

In addition, startup also sells “firewood coffee” to replace the wood firewood. Currently, there is no official agreement to continue using London coffee oil, but bio-bean hopes to find new markets and applications soon. The potential market for this project is the United States, which consumes the most coffee on the planet with 400 million cups of coffee / day.

The “refrigerator” without plugging in the power still keeps the food fresh 9 times better than normal

Preserving fresh and modern food for up to 27 days, without “harming electricity”, these are great benefits that a special “refrigerator” has been invented by a Nigerian teacher to bring to life. poor people here.

The simple but unbelievably effective inventions, which don’t cost too much, are the things that poor rural people in Africa always dream about. Even in modern life today, basic electrical equipment such as refrigerators also become extremely “luxury” for the people here due to remote terrain conditions and the cost of using Electricity is too expensive.

Luck has come to poor Nigerians when a special cold storage tool works to preserve food in no way inferior to the refrigerator invented by Mohammed Bah Abba, a Nigerian teacher.

Special cold-keeping tool works to preserve food in no less than a refrigerator.

This “one-of-a-kind” refrigerator doesn’t need to be plugged in, doesn’t cost much, can even be “portable”, but is especially effective in hot and dry weather conditions that make fruits and vegetables easy. The fruit and the food were quickly damaged, rancidly preserving the food for nearly a month.

Mohammed Bah Abba

Mohammed Bah Abba, the inventor of the cooling system, especially changed the lives of poor Nigerians.

Mohammed Bah Abba was born into a family with a tradition of making pottery and clay. As a Nigerian son, knowing the consequences of the scorching heat in Africa, as well as the wishes of the poor people, in the late 1990s, Mr. Mohammed created a solid “refrigerator”. Special application of traditional pottery making technology.

This “refrigerator” does not need to be plugged in, preserving food 9 times longer than normal conditions.

Based on the ancient idea of ​​a ceramic vase holding cold water, Mohammed created a special “refrigerator” with a “vase in the bottle” mechanism. Two large and small ceramic vases are inserted, in a large vase or space between two vases will be filled with wet sand, and small ceramic vases will be used to store food and cover with a wet cloth.

Structure of the “refrigerator”

The construction of the “refrigerator” consists of two large and small ceramic jars that are interlocked, the space between the two jars will be filled with wet sand, and small ceramic vases will be used to store food and cover with a wet cloth. .

In order for the two pots to function as a refrigerator, they should be placed in a cool, dry place. Then the water in the sand has been poured from the beginning to evaporate, the inner pot is cooled to only 4 degrees C, preventing bacteria from growing and keeping the food fresh.

The water in the wet sand will evaporate, the inner pot is cooled to only 4 degrees Celsius, preventing bacteria from growing and keeping the food fresh.

It can be said that this special “refrigerator” of Mr. Mohammed is a testament to the “modern but not harmful” invention when startlingly cheap. It only costs 20 to 90 thousand dong (from $ 2 to $ 4) for each one, does not use electricity and can preserve food from fish, vegetables, fruits to 27 days, fold 9 times more than 3 days at normal temperature.

It can be said that this special “refrigerator” of Mohammed helps people store food for up to 27 days.

This effective “average bottle” system has really changed the lives of poor Nigerians, the ability to store food for a long time and fresh longer for them to sell agricultural products is also higher. Since these pots are available, people here will not need to go to the market to buy food anymore, it is very convenient but also saves a lot of time.

Before his death in 2010, Mr. Abba constantly improved the cold storage system, then he used his own money to hire local factories to produce 5,000 “refrigerators” distributed to 5 villages. Jigawa and 7,000 “refrigerators” for Nigerian locals.

The refrigerators created by this Nigerian teacher have significantly improved the lives of the people here, helping them to sell farm produce at a higher price, saving a lot of costs.

So far these “super saving” refrigerators have been widely used in rural areas in Nigeria, Cameroon, Chad, Eritrea, and Sudan. In 2000, Mohammed Bah Abba was awarded the Rolex Award for Enterprise award for honorable inventions. Time magazine once called for the invention of Mohammed’s groundbreaking chiller as one of the great inventions of the year.
