Compared to other mechanical technologies, including pumped hydro and CAES, the flywheel is a fast-responding, short-duration discharge technology used primarily for frequency regulation. A flywheel stores rotational energy in an accelerated rotor. When there is a surplus of electrical energy, the flywheel is accelerated, and when energy

Despite sharp differences in government policy, the views of the U.S. public on energy and global warming are remarkably similar to those in Sweden, Britain, and Japan. Americans do exhibit some differences, placing lower priority on the environment and global warming, and with fewer believing that "global warming has been established as a serious problem and
Flywheels can exert torque that alters the Station''s attitude motion, either intentionally or unintentionally. A design is presented for a once planned experiment to contribute torque for Station attitude control, while storing or discharging energy. Two contingencies are studied: the abrupt stop of one rotor while another rotor continues to
There are encouraging signs Scotland''s oil and gas industry is emerging from its recent downturn, thanks to the efforts of the men and women who have made it an international success story. Despite raising £330 billion in tax revenues for the UK Treasury, Westminster has repeatedly failed to provide adequate support for the industry and.

Having a very high energy density, flywheels could be used as one single energy storage and attitude control device, forming a combined energy and attitude control system. This combination could lead to different improvements on mission design, e.g. mass saving, performance enhancement, reliability increase and so on [1], [2] .
The HTS flywheel has an angular momentum capacity of 0.083 J sec and stores 2.32 kJ at 530 krpm. Its energy storage capacity is approximately 45 Whr/kg With an energy density around 370 kJ/L. The system is ideally suited for low earth orbit (LEO) energy storage, power generation and attitude control of spacecraft such as nano satellites.
