Experimental study of the performance of a circular tube solar collector with closed-loop oscillating heat-pipe with check valve (CLOHP/CV)
Rittidech, S.; Donmaung, A.; Kumsombut, K. - In: Renewable Energy 34 (2009) 10, pp. 2234-2238
This paper describes the performance of a circular glass tube solar collector with a set of closed-loop oscillating heat-pipes with check valves (CLOHP/CV). The assembly was divided into three sections, i.e. circular glass tube, adiabatic gap and condenser water tank. A circular 10-set glass...

The effect of temperature and compression during pyrolysis on the density of charcoal made from Australian eucalypt wood
Somerville, Michael; Jahanshahi, Sharif - In: Renewable Energy 80 (2015) C, pp. 471-478
Charcoal produced from sustainably grown biomass can be used to reduce the net CO2 emissions from iron and steel making operations. However careful control of pyrolysis conditions is required to produce charcoal with the necessary properties to optimise substitution for coal and coke in specific...

Biogas scrubbing, compression and storage: perspective and prospectus in Indian context
Kapdi, S.S.; Vijay, V.K.; Rajesh, S.K.; Prasad, Rajendra - In: Renewable Energy 30 (2005) 8, pp. 1195-1202
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours. Presently, it can be used only at the place where it is produced. There is a great need to make biogas...
