Ocean energy technologies have been around for decades. But for a variety of reasons, including rising oil prices, technological advancements and the sheer grit of a handful of pioneer developers, ocean energy has made a huge splash only in the last years. The specialists working in this field concluded that generation of electricity from wave energy may be economically feasible in the near fut...

The amount of electrical energy produced over the lifetime of DTand DHe-fusion power plants is compared to the total amount of energy required to procure the fuel, build, operate, and decommission the power plants. The energy payback ratio is similar for the two quite different fuel cycles, 31 for DHe-fusion and 27 for DT-fusion, even though there is a significant difference in the source of in...

Suction pumps form an important part of the equipment for field treatment of emergency patients (ECRI, 1979; Silverton, 1980; Rossi, 1983; Dick, 1985). Basically, a distinction must be made between devices that are mechanically driven (handor pedal-operated) or driven by external energy, i.e. electrically or pneumatically. The advantage of the latter is that they are not depending on any exhaus...

the production of a stable solution by such means is. The apparatus introduced by Captain Hodgkinson and Mr. Hutchinson can be installed in any hospital or institution supplied with electric current ; and with supplies of salt and lime from the bazaar, unlimited supplies of E. C. can be manufactured at a cost of approximately four annas per gallon. Once prepared the solution contains about 2.5 ...

We investigate the impacts of electricity market restructuring on fuel efficiency, utilization and, new to this area, cost of coal purchases among coal-fired power plants using a panel data set from 1991 to 2005. Our study focuses exclusively on coal-fired power plants and uses panel data covering several years after implementation of restructuring. The estimation compares how investor-owned (I...

The growth in the demand of electrical energy is leading to load on the Power system which increases the occurrence of frequent oscillations in the system. The reason for the oscillations is due to the lack of damping torque which is required to dominate the disturbances of Power system. By using FACT devices, such as Unified Power Flow Controller (UPFC) can control power flow, reduce sub-synch...

The field of conventional energy conversion using radioisotopes has almost exclusively focused on solid-state materials. Herein, we demonstrate that liquids can be an excellent media for effective energy conversion from radioisotopes. We also show that free radicals in liquid, which are continuously generated by beta radiation, can be utilized for electrical energy generation. Under beta radiat...

During the last decade, a series of valuation studies have made attempts at estimating the external environmental costs of various power generation sources. The purposes of this paper are: (a) to explore some of the ethical limits of the economic valuation of environmental impacts; and (b) to analyze what the implications are of these limits for the social choice between different electric powe...

Manipulation of single spins is essential for spin-based quantum information processing. Electrical control instead of magnetic control is particularly appealing for this purpose, because electric fields are easy to generate locally on-chip. We experimentally realized coherent control of a single-electron spin in a quantum dot using an oscillating electric field generated by a local gate. The e...

In this paper, we conduct a feasibility study of the wind energy potential in Gaza, which suffers from a severe shortage of energy supplies. Our calculated energy harvested from the wind is based on data for a typical meteorological year, which are fed into a small wind turbine of 5 kW power rating installable on the roof of residential buildings. The expected annual energy output at a height o...
