Solar Powered Cold Stores<br />
By Martin Hodgkinson<br />
Dr Ola posed me an interesting challenge.<br />
He has contact with 100 + farmers<br />
in Nigeria producing 3300 tons of<br />
food each year of which 70% perishes<br />
or is wasted within 3 weeks of harvesting<br />
because of inadequate storage<br />
and no distribution facilities. Martin<br />
can you set up a distribution depot<br />
Well I don't have £2-£3 million on a<br />
peg ready to use. What my friends and I have is a 'can do approach' and loads of creative<br />
problem solving ideas. There is also 12+ hours per day of sun in Nigeria. If the farmers can<br />
keep the food for 6 weeks rather than 3, they may be able to use or sell 30% more. That could<br />
double their income with still a 40% waste factor.<br />
The initial idea was to use a solar powered refrigerated container. The Chinese sell them for<br />
$40,000 - $50,000, which have to be connected to back up land line power not available to our<br />
farmers. and much too expensive. Following discussions with over 12 Engineers and Builders<br />
our specification solution is gradually being fine tuned, to take account of what’s available in<br />
Nigeria and the technical details necessary to provide a 'Solar Powered Cold Room'.<br />
Where are we now We are still at the initial design stage of working out the best method of<br />
producing a cold store that will prolong the life of the food produced. We hope to interest<br />
some University Mechanical Engineer students to work with us to fine tune the design to enable<br />
us to build a proto-type on our land in Nigeria. The proto-type will probably use locally<br />
made blocks to form a cold store with an air lock and we think a solar powered air conditioning<br />
unit on the side of the cold store.<br />
