Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

HVAC (heating, ventilation, and air-conditioning) systems vary depending on the complexity of room units size from single rooms to large systems, central control, which serves several areas of a building. In large, modern office buildings with heat gains from lights, people and equipment, interior spaces often require constant cooling. Rooms within the building itself (rooms with exterior walls, ceilings or roofs), it may be necessary to heat and / or cooled the weather conditions change hourly or daily outside. In buildings over one story in height, perimeter zones in the lower levels tend to be the penetration of air infiltration without so much control. (more…)

A propulsion alternative is to transfer power to the vehicle and then have a magnetic structure on the vehicle that can create a moving field that, in turn, interacts with a conducting guide way to provide propulsion. This is called a short stator linear induction motor (or linear asynchronous motor), generally referred to as a Linear Induction Motor. It is possible to put the powered winding on the guide way and induce currents in a conductor on the vehicle, in which case it would be a long stator design, but this turns out to be an expensive and inefficient approach to maglev propulsion.

The pace of innovations in batteries has not matched the remarkably fast evolution in the development of portable electronic technology. Batteries are widely regarded as the weak point slowing the rapid innovations in portable technology. Chief among consumer complaints are that batteries do not last long enough and that they do not last as long as the manufacturer claims they will. (more…)

Although the focus of many policy studies of climate change is on establishing the causal links between anthropogenic systems, emissions of greenhouse gases climate change, the line of causation also runs the other way. Short-term fluctuations in climate conditions, particularly in the temperate zones on the planet, affect energy consumption. If the popular expectation that the climate will become warmer becomes a reality, we can expect winters and summers that are warmer than those of the past. (more…)
