Hybrid battery and flywheel energy storage system for LEO spacecraft [PDF]
Thirteenth Annual Battery Conference on Applications and Advances. Proceedings of the Conference, 2002 The use of flywheels for energy storage was probably the second thought after the wheel was invented. With the recent developments in composite materials, magnetic materials and the use of microprocessors, flywheel energy storage has wide applications in many facets of our lives.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...

The potential impact of small-scale flywheel energy storage technology on Uganda’s energy sector
Journal of Energy in Southern Africa, 2017 The energy crisis in Uganda has caused a sharp decline in the growth of the industry sector from 10.8% to 4.5% between 2004/5 and 2005/6. This crisis has escalated the power disruptions, which have had adverse effects on various sectors.

Product Positioning and Incentives to Innovate
Journal of Economics &Management Strategy, EarlyView.ABSTRACT This paper shows that product positioning affects the incentives to invest in process innovation. The result is found using a model of price competition with three firms under horizontal product differentiation—and then extended to a more general Bertrand triopoly.
