Gourd saves Pentium computer 11 April 2003

The gourd computer prevents overheating (photograph: François Laureys/IICD)

Within weak were the brand-new Pentium 4 of Sylvestre Ouédraogo, docent rural economy on the university of ouagadougou in Burkina Faso. The computer did not appear resistent against 40 degrees celsius. Ouédraogo considered a solution with the peel of a gourd.
Second-hand the computers Europe stayed away to work, but new, powerful Pentium ' melted ', seven days still no after purchase. How that to solve? The Burkinabese docent were possible the rooms improve to cool - but that appeared too expensive. ' there another option remained open, ' Ouédraogo say. A computer system develops that less warmth-sensitive was.'

The docent got an idea then he on the market a large battery gourds saw lying. Many copies here are large enough there all elements of a computer in be able accommodate. And I assumed that the natural peel less would become rapidly warm than metal a formwork, thus Ouédraogo.

The metal frame of the computer went eraf and in the gourd Ouédraogo tried place the basis components of a computer: moederbord, hard disk, CD-Rom player, graphic card, feeding, koelelementen.

Slots and savings

Taking into account the bending of the gourd I have vervolgens calculated where each component had come, and where in the peel slots and savings for CD-Rom, to/from bud, connections etc. gezaagd had become. Afterwards I to a welder have asked a metal make frame that all components could keep within the gourd, and am I the thing in each other will put, the docent says rural economy.

Ouédraogo want do tests still a couple with several processors certainly know that the warmth incurs effectively less high in the gourd peel. Afterwards he will examine or its idea saleable is. Omdat de kalebas een natuurproduct is en de afmetingen kunnen verschillen, is niet helemaal zeker of zijn uitvinding voor massaproductie geschikt is.

De kalebas-computer is een voorbeeld van hoe een concreet, bestaand probleem opgelost kan worden met behulp van lokale middelen. But the Burkinabees have still another reason with its project: others aware make of the fact that also the computer but an ordinary use object is, and that one does not have be frightened for technology.

'Onbruikbare zooi'

Ouédraogo also President of Yam-Pukri (have been translated rather ' open Your Mind '), an association which by means of three telecentra in Ouaguadougou, the capital of Burkina Faso, computer trainings looks after and cheap offers Internet access to students and unemployed person.

Although second-hand the computers from Europe are still hardly reused in Burkina Faso, Ouédraogo believe, however, that there serious work of must be made. Disadvantage of the cargos old computers is, however, that there frequently ' unusable zooi ' of tussenzit: broken display devices, break keyboards, total burned through computers. Ouédraogo: 'Laatst zaten er in een containerlading met zo'n 20 computersets maar twee bruikbare tussen! Dan gebruik je ons echt als dumpplaats.'
