Brown Dwarf Research Paper
1. Brown Dwarfs
A brown dwarf is a celestial body that has never quite become a star. A typical brown dwarf has a mass that is 8 percent or less than that of the Sun. The mass of a brown dwarf is too small to generate the internal temperatures capable of igniting the nuclear burning of hydrogen to release energy and light. A brown dwarf contracts at a steady rate, and after it has contracted as much as possible, a process that takes about 1 million years, it begins to cool off. Its emission of light diminishes with the decrease in its internal temperature, and after a period of 2 to 3 billion years, its emission of light is so weak that it can be difficult to observe from Earth. Because of these characteristics of a brown dwarf, it can …show more content…
In some major oil producing nations, peak oil has already been reached, and there are increasing fears of global warming. Consequently, many countries are focusing on the switch to a low carbon economy. This transition will lead to major changes in the supply and use of electricity. Firstly, there will be an increase in overall demand, as consumers switch from oil and gas to electricity to power their homes and vehicles. Secondly, there will be an increase in power generation, not only in terms of how much is generated, but also how it is generated, as there is growing electricity generation from renewable sources. To meet these challenges, countries are investing in Smart Grid technology. This system aims to provide the electricity industry with a better understanding of power generation and demand, and to use this information to create a more efficient power …show more content…
Some are estimated to be continental or even hemispheric in size, while other are believed to be much smaller. Though the actual boundaries and sizes and shapes of the plates are not known for sure, it has been postulated that there are six major plates and somewhere around the same number of smaller ones. Most of the plates consist of both sail (continental) and sima (oceanic) crust. They are in contrast movement, though they move at an extremely slow pace, and these movements cause frequent interactions between
