Limits to Energy Conversion [PDF]

open access: yesIEEE Transactions on Automatic Control, 2022
A consequence of the Second Law of thermodynamics is that no thermodynamic system with a single heat source at constant temperature can convert heat into mechanical work in a recurrent manner. First we note that this is equivalent to cyclo-passivity at the mechanical port of the thermodynamic system, while the temperature at the thermal port of the ...

Solar Energy Conversion [PDF]

open access: yesAIP Conference Proceedings, 2007
If solar energy is to become a practical alternative to fossil fuels, we must have efficient ways to convert photons into electricity, fuel, and heat. The need for better conversion technologies is a driving force behind many recent developments in biology, materials, and especially nanoscience.

Economical sustainability of integrated photo voltaic and hydroponic systems for rural areas

open access: yesJEMMME (Journal of Energy, Mechanical, Material, and Manufacturing Engineering), 2022
Hydroponic plantations are an effort of future agricultural technology, and this is due to population growth and increasingly saving agricultural land. Besides that, hydroponics can trigger rural economic development by opening employment opportunities ...

Sustainability and Energy Conversions [PDF]

open access: yesMRS Bulletin, 2008
AbstractA sustainable global energy system requires a transition away from energy sources with high greenhouse emissions. Vast energy resources are available to meet our needs, and technology pathways for making this transition exist. Lowering the cost and increasing the reliability and quality of energy from sustainable energy sources will facilitate ...
