Its free consultancy service gives advice to people and organisations in developing countries regarding the different applications of non-conventional sources of energy as a cost-effective alternative to combat the energy crisis. Ferdinand Kroon, the outgoing chairman, illustrates, 'Our sole purpose is to solve problems using the renewable energy technologies. For example, we advised a fisherman in Zimbabwe to use solar energy to maintain the temperature of the water so that the fish could survive. Similarly, we devised a simple method of digging a well using a piston pump in a remote place in India. In other words, we try to make things as simple as possible.'
The WOT consists of several groups which can be broadly categorised into the consultancy group and the development and maintenance group. Technical questions regarding small-scale sustainable energy can be addressed to WOT with details concerning the country and its local conditions.
Ferdinand, 'We receive around 100-150 queries each year that are answered to the best of our knowledge but unfortunately we hardly get any feedback from anyone regarding the implementation of the advice given by us, which is really disappointing. 'When asked about the reason for the limited use of wind, water and sun as the energy sources in developing countries, he explains, 'The initial investment needed is very high, which discourages these nations to exploit the resources. Also, there are only a few companies manufacturing equipment meant for harnessing such energy sources. This lack of competition keeps the prices high, and a solar panel thus means quite a lot of money for a developing country.'
Anyone interested can make an appointment to tour the WOT field on the Achterhorst. It shows devices working on solar energy such as a parabolic solar cooker and a solar shower. In addition, there are different kinds of windmills and pumps. Interestingly, the very design of the WOT laboratory is based on the principle of passive solar energy -- it remains warm in winter and cool in summer. WOT WOT members are volunteers supported by a small professional staff. The volunteers contribute 12 euros per calendar year. Anyone interested in the activities of the WOT either to join them or to ask their advice can contact them on Wednesday evenings--- 20-00 to 22-00 hours or via e-mail at [email protected]. More information can be obtained at www.wot.utwente.nl
The WOT is organising a Technical week ( 15 t/m 21 June, 2003) during which the various elementary techniques of harnessing the renewable sources of energy will be demonstrated. Students pay 190 euros and employees 285 euros.
