This previous week I have been researching about including a Manometer in the design. This is a fundamental safety feature which will reduce risks for the people when using the Biogas Digester, noting if the pressure is at a stable point.

My team are now looking into the dimensions of the digester and also what materials can be used and the gas which is yielded from these materials.

Within the next few weeks, we will begin the typing up of the instruction manual.


Meeting with Dan

We met with a representative from Engineers without border, Dan (nice meeting you if you’re reading this) who gave us great feedback. Taking on board his advice, we are working back from the start to correctly go about assessing solutions to the issues regarding fuel for cooking.

For next week, we are researching about other solutions other than biomass. Researching into Tidal energy, Solar energy etc… Looking into the advantages and disadvantages of each of the other possible solutions, as engineers we have to remember our responsibilities in creating solutions which are economically, socially and environmentally correct.

Gas storage and pressure is still an issue we are looking to resolve, anti-flatulence drugs may be needed!



We have a preliminary design made on Solidworks which will be improved and updated in due course. Matthew is producing a presentation to be shown to the representative from EWB coming in next week. We hope to finalise our design and costing within the next 2 weeks and then start on creating a instruction manual.

The 2 designs we have in mind both have the same basic digester designs but differ with the storage of the gas either storing within the inner tubes of vehicle tires or within another tank/ARTI design.

Design Research

This week we researched into possible designs of a bio-gas digester. There is a generic design for the digester itself but the variance of the systems are due to differences with how the gas is collected and stored.

In the following week, we will research into two possible designs for collecting the bio-gas produced. It will be either collecting the gas within a separate (water tank) gas tank collector or storing the gas within the inner tubes of a vehicles tyre. Both of these ideas highlight the issue of the pressure in regards to the gas which would be needed to transport and store  the gas from the digester.

Next session, an initial design on paper will be concluded and also a power point produced to be shown to a representative of Engineers without borders

Week One- Starting off

The first week consisted of deciding as a team, what area of the Engineers without borders (EWB) project we were going to focus on. We decided to tackle the issues of energy in Lobitos (South America, North Peru), more specifically the issues surrounding the use of natural gas, a fossil fuel, for cooking purposes.

The team consists of;

  1. Rizwan Farooq (Project Manager) -Mechanical Engineer
  2. Ramil Abdrashitov – Mechanical Engineer
  3. Shahad al-Sulaiti – Electrical & Electronic Engineer
  4. Matthew Saint – Mechanical Engineer

We each initially came up with our own issues we wished to tackle, which were

  • Fuel for cooking
  • Cooling of vaccines/medications at medical facilities
  • Purification of water

and each researched into the pros and cons of each design in comparison to the system which is already in place. Researching into the environment and resources available in Lobitos, we concluded that an alternate fuel for cooking was the most interesting and challenging area. We chose to pursue a design based upon Biogas and have started research into possible designs of a Biogas digester and the possible issues surrounding the system for our meeting next week.
