A tracking parabolic concentrator was built from easily available and affordable components. Simplicity and ease of assembly were prime considerations. Considerable experience was gained in the design, assembly and testing. The system performed reasonably well considering its simplicity and...

The performance of a thermoelectric generator, among other aspects, depends on the use of an effective heat sink. While forced cooling using either air or water (or other coolants) is efficient, it is parasitic on the generated power and/or bulky and inconvenient. Heat pipes are known to be...

During the winter months in regions where constant electric power supply cannot be relied upon, power may be derived parasitically from heating stoves. A proportion of heat from these 20–50 kW wood or diesel-heated stoves may be utilized to drive a thermoelectric generator (TEG) consisting of...
