About this Blog

This is the blog for Lincoln's EWB-UK placement in Ujire in Karnatica in Southern India. I am working for SELCO, a solar lighting social enterprise, on the development of a solar food dehydrator, a device used to increase the life of foods. The aim of the placement is to make it fully functional, more efficient and to conduct market research in order to help market the product to customers living in rural areas enabling them to break the poverty cycle.

Failure

This week I have developed a cheap, sixteen brick rocket stove which can be used in combination with the dryer, giving good combustion once lit and good temperatures.

This however was the only success. The metalwork in the dryer restricts the flow of smoke through the dryer, causing the food to become smokey, a problem which I have been as yet unable to get around. It is difficult to get good heat exchange, good air flow and a simple design.

I visited a steel workshop today, searching for alternative materials for the dryer. It was amazing to see the complete lack of health and safety procedures, with people arc welding in flip flops and without a face mask... but nobody was hurt while I was there.

Good luck to anyone in the UK who will collect their A-level results tomorrow!

    I probably should have read this sooner... but isn't it funny how you mention A level results at the end and make the title of this blog 'Failure' Haha. See you soon!
