Direct heat energy conversion into electrical energy: An experimental study

Integration of Microprocessor Technology into Energy Conversion / Electrical Machines Courses

___ Advances in microprocessors and micro controller technologies have brought with them many opportunities. These opportunities are being exploited to great economic benefit in the developed world and to a lesser extend by developing countries. At the same time the nature of our industrial plants is changing and computer chips are encountered even in the most elementary equipment. However many...

Thermoelectric Oxide Modules (TOMs) for the Direct Conversion of Simulated Solar Radiation into Electrical Energy

The direct conversion of concentrated high temperature solar heat into electrical energy was demonstrated with a series of four–leg thermoelectric oxide modules (TOM). These temperature stable modules were not yet optimized for high efficiency conversion, but served as proof-of-principle for high temperature conversion. They were constructed by connecting two p(La1.98Sr0.02CuO4) and two n-type ...

Energy Conservation Potential of the Heat Pipe Heat Exchangers: Experimental Study and Predictions

The energy conservation potential of the heat pipe based heat exchangers (HPHXs) was studied in this research. To this end, a typical climate chamber as the representative of an air conditioning system was established. The performance characteristic of a typical eight-row HPHX was obtained based on the one week operation (168 h) to determine the performance characteristic curves. The coil face ...

Solar Energy Conversion into H2 Energy Using Ferrites

A cation-excess (Ni,Mn) ferrite N~o.~zMno.51Fe2.0504.0 with a single phase was synthesized by heating the mixture of corresponding metal salts and oxide in 5% 02175% C02120% N2 gas mixture for 18h at 1100C. It could be thermochemically activated to form a cation-excess ferrite Nio,5z~l+s~Mno.51~l+6~Fe2~05~1+6~0440 in N2 gas at elevated temperature: The ( value was 0.03 1 at 1100C. The activated...
