Since incandescent light bulbs use more energy than alternatives such as CFLs and LED lamps, many governments have introduced measures to ban their use, by setting minimum efficacy standards higher than can be achieved by incandescent lamps. Measures to ban light bulbs have been implemented in the European Union, the United States, Russia, Brazil, Argentina, Canada and Australia, among others. In the Europe the EC has calculated that the ban contributes 5 to 10 billion euros to the economy and saves 40 TWh of electricity every year, translating in CO2 emission reductions of 15 million tonnes.
How much does the incandescent light ban in Europe contribute to the economy each year?
****
The answer: 5 to 10 billion euros

Rome offers no native creation myth, and little mythography to explain the character of its deities, their mutual relationships or their interactions with the human world, but Roman theology acknowledged that di immortales (immortal gods) ruled all realms of the heavens and earth. There were gods of the upper heavens, gods of the underworld and a myriad of lesser deities between. Some evidently favoured Rome because Rome honoured them, but none were intrinsically, irredeemably foreign or alien. The political, cultural and religious coherence of an emergent Roman super-state required a broad, inclusive and flexible network of lawful cults. At different times and in different places, the sphere of influence, character and functions of a divine being could expand, overlap with those of others, and be redefined as Roman. Change was embedded within existing traditions.
What did the Romans do for those deities that favored Rome?
****
The answer: Rome honoured them

A few years after its foundation, Montevideo became the main city of the region north of the Rio de la Plata and east of the Uruguay River, competing with Buenos Aires for dominance in maritime commerce. The importance of Montevideo as the main port of the Viceroyalty of the Rio de la Plata brought it in confrontations with the city of Buenos Aires in various occasions, including several times when it was taken over to be used as a base to defend the eastern province of the Viceroyalty from Portuguese incursions.
The importance of Montevideo as the main port of the Viceroyalty of the Rio de la Plata brought confrontations with what city?
****
The answer: Buenos Aires

Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.
In what device are small motors commonly found?
****
The answer:
electric watches
