Electricity monitors. Even if a homeowner has reduced electricity consumption to a minimum, there is always an other watt or two that can be saved. That is the theory behind electricity monitors, which use microchip technology and digital display to calculate the dollars-and-cents value of the electricity being used in a house at any given moment. The idea is that once a homeowner sees what he is actually spending for electricity, he will become far more conscientious about turning off lights and, in the case of electric heat, lowering the thermostat. According to tests by the University...
...session, electrodes are attached to one or both sides of the head, and 80 to 100 volts applied for as much as one second. That produces enough current to light a 100-watt bulb and causes a brain seizure, which can be traced on an electroencephalogram. Patients regain consciousness within minutes but may be groggy and confused for a while. Usually six to ten ECT sessions are given within a two-to-three-week period...
...come from the stage; the actresses are silent. These disembodied voices blare over the same loudspeakers that have simulated the storm for ten minutes. In the din--enough to drive anyone mad--poor Lear's voice drops out, his volcanic speeches unheard, his personal apocalypse mastered by a 50-watt amplifier...
...saves only about $40 a year in fuel bills. The promising new frontier is photovoltaics, the direct conversion of sunlight into electricity by using silicon-crystal panels. Though the price of photovoltaic cells has been cut in half since 1975, the cost is still $9 per watt,*equal to a staggering $40,000 for a one-family home. Still, advances are being made in the efficiency of panels and methods to store power at night. Last month, Texas Instruments claimed one breakthrough that should lower the costs: a self-contained photovoltaic system, which changes the sunlight into a fuel suitable...
...even in California the science of photovoltaics is in its infancy, and the cells remain expensive and not very efficient; the 1,500 sq. ft. of units required to power a typical one-family home would cost at least $40,000. Electrical power is measured in the number of watts that can be generated from a single power source. The cost of building and maintaining a plant to generate a single watt is about $1 from a coal-powered utility and about $1.25 from a nuclear power plant. The cost of a watt from photovoltaic cells has come down from...
