MY FIRST DAY AT UNIVERSITY

MY FIRST DAY AT UNIVERSITY


     MY FIRST DAY AT UNIVERSITY WAS ON 28 MARCH.IT WAS MY FIRST DAY OF ORIENTATION.IT WAS FUN DAY FOR ME TO ENTER INTO UNIVERSITY.FIRST ACTIVITY WE DID WAS ICE BREAKING.IN ICE BREAKING GAMES I LEARN ABOUT MY NEWS FRIENDS BIODATA.AND THEIR HOBBYS AND WHAT THEY LIKE AND DISLIKES.

WE ALSO DID DRAMAS AS A GROUP TO LEARN ABOUT GROUP WORK.SECOND DAY WE DID DRAWING TO TEST OUR DRAWING SKILL AS A STUDENT AND ALSO THROUGH DRAWING WE CAN SHOW WHAT WE LEARN SO FAR IN TASK THAT WE DID.THIRD DAY WE DID SOME EXERCISE TO REFRESH OUR BODY AND MIND.AND WE ALSO DID SOME QUIZ BASED ON GENERAL KNOWLEDEGE.ON FOURTH DAY WE REGISTER  OUR SUBJECT OF MY COURSE.IT WAS VERY FUN TO ENTER UNIVERSITY.

THE SOLUTION

The Biogas Backpack is a pillow shaped balloon from flexible, gas tight material, plastic sheet and fabric. The two inner layers are made of gas tight PE-sheet, welded at the two open ends and equipped with a welded, threaded flange, holding a mini ball valve. The backpack is filled with biogas from the biogas plant by simple pressure equalization instead of by pump or compressor. Therefore, it does not need to be equipped with a security valve to release gas in the case of over pressure.

To use the Biogas Backpack efficiently, it would make sense to produce the biogas in one central, technically advanced biogas plant. This way, farmers in the surrounding areas could contribute to the biogas production by selling substrate to the plant owner in exchange for biogas and fertilizer.

Because of the limited amount of biogas, the high content (30-60%) of non-flammable CO² in biogas and the non-pressurized status of the gas, there is no risk of an explosion. Even if in contact with open fire, the backpack does not explode, but rather burns down in a controlled manner. To avoid accidents with leaking gas, the backpack is designed to be stored outside the house.

BACKGROUND INFORMATION

Combustible materials which are used for cooking, such as firewood and charcoal, are associated with a range of problems in many countries. Gathering these materials is time-consuming and difficult, also, because they are often in short supply. In addition, cooking with these materials can cause significant health problems. Replacing wood fuels, biogas can alleviate such problems while simultaneously reducing deforestation and soil erosion. However, once produced in biogas digesters it is very difficult to transport the gas to the respective households.

SOCIAL IMPACT

The Biogas Backpack aims to provide poor rural households with an affordable source of energy for lighting or cooking, thereby improving living conditions. Helping to avoid the time consuming task of collecting fuel wood, the biogas backpack helps to ease the daily work of women in developing countries. In addition, health risks can be minimized as burning biogas is nearly smokeless.

This solution was developed in order to facilitate the sale of biogas in developing countries and therefore makes it possible to start a business.
