Santa Run 2011 – a Sea of Santas Brings Winter Cheer to East London

On Sunday 4th December 2011 two of our trustees (Marcus & John) will be joined by a group of secondary school friends in the 5km Santa Run in Greenwich Park, London. In case you don’t know, the Santa Run is a fun run except the runners are kitted out in Santa costumes!

DT depends on the generous donations of its supporters to keep going. To date, the Santa Run raised over £1300 in much-needed funding.

It’s not too late to support our runners! Simply visit our fundraising page to find one of our red-clad, bearded runners and make any donation you can – and be sure to leave us a message to say hello.

DT Team

How DT works

Our technology is initially developed at Imperial College London and City University and then undergoes further development and trialling in conjunction with local overseas partners. DT also trains its partners to manufacture, use and maintain this technology to ensure the change is sustainable.

Once the technology has been successfully trialled we then seek its local dissemination, where needed, either through local enterprises or larger bodies. DT has successfully trialled technology in six countries and currently has ten projects at different stages of development.

DT’s aims are closely aligned with the Millennium Development Goals. Our projects include the provision of clean water and emergency transport and technology to increase food production and enable local income generation.

City University student shares his experience of a Developing Technologies project

Last month we visited the Engineering department at City University to meet some of the young engineers who have been working on Developing Technology projects – in particular the team working on the Motorcycle Ambulance Trailer.

How did you find out about DT and its’ projects? Why were they interesting for you?

At the beginning of my final year, we were given a presentation about the work that developing technologies does and the tasks which we would be expected to carry out.  I was impressed by the fact that the design work we would be doing would go towards really providing a solution for those who need it the most and I was attracted by the challenges posed in using our design skills to come up with innovative solutions to the problem at hand.

What project did you work on – why did you choose it in particular?
We were tasked to design an intermediate means of transport that would be cheap and rugged to be able to transport goods and people along rough terrain to markets, or hospitals, or wherever was necessary.  The vechicle had to have the flexibility of a motorbike, but the safety, comfort and capacity of a 4×4.  The final outcome of the project would be to provide a given village with a vehicle that would be easy to run and maintain so that it could be used as a cheap taxi and thus save people from the 2 to 3 day treks to market and thus increase productivity and provide emergency transport in places where hospitals are few and far between.
What aspect/s of the project were you working on and what was the task?
In that first year, we were a group of 4 students, and thus, we worked together on all aspects of design and manufacture.  I found that my strengths lay in FEM and computer aided design, as well as presenting our work to the various stakeholders.  I taught myself to weld in order to put together the steel frame of the vehicle and I sourced cheap parts for the vehicle.
What were the biggest challenge/s? What was the most important thing you learnt from the experience?
The biggest challenge was the budget to which we had to stick.  I learned that the best solution is almost never the cheapest option, and hence, we had tough dicussions as to what we could actually afford and thus the design was changed, and changed again until we came up with innovative solutions and compromised in some areas.
How far did you come with the project? Where does it sit now? What are the next steps?
My group produced – in our own time, and after we had completed our degrees – the first prototype.  This was not something we were expected to achieve in the first place, but we became really invested in the project and happily worked to build this.  The next year, I was asked to present the project to the students, and we managed to get 20 students interested, and as I was lucky enough to be working at City University, I was able to follow the improvement and changes proposed and provide my advice and guidance to the new group of students working on the project.  We hope to have a prototype for testing by the end of june and have a vehicle for manufacture and test out in Ghana by the end of next year.
Are you still involved with the project now? What are your plans for next year?
I am involved in the project in my spare time and I hope, if my work at City carries on, to carry on providing any help that I can.  I am at the beginning of my engineering career at the moment, and I don’t know where it will take me, but my experiences with developing technologies has brought me to the realisation, that whatever I do, I want to be doing something that means more to the people I am helping.  Something that will mean more to me and something that means more than just a job in engineering.

Percussion Drill – Sierra Leone

James, our most recent engineering placement has returned from the village of Bo in Sierra Leone. Here is summary of the progress made.

Repair and maintenance

James carried out some much-needed repairs and maintenance to the drill tools which had been stored on site since July 2010. Access to materials is always a challenge in the location Developing Technologies works, but James showed great ingenuity and resourcefulness in successfully repairing the drill engine as well as the pulley system.

Drill behaviour through different rock types

James’ research involved testing the percussion drill in new rock types.

Drilling challenges below the water level

A major challenge associated with percussion drilling is drilling into material that is saturated with water. This happens when either the main aquifer is reached or when a lot of water is added to aid the drilling process. As the drill moves through saturated material, the walls often do not have enough cohesion to maintain their shape and can slump into the bottom of the hole. This means that the drilling process becomes slower – more material having to be excavated without increasing the well depth.

Building on the operational data from James work, DT is developing several possible solutions to this problem which we aim to test in early 2011.
