Not suitable.
On Mars, 95% of the gas is carbon dioxide. Carbon dioxide warms Earth, but not Mars. Because the atmosphere on Mars is thin, with a density less than 1% of Earth's atmosphere, there is no way to conserve heat. As a result, the surface temperature of Mars is very low, rarely exceeding 0 degrees Celsius in winter; The temperature of Mars can even reach -140 degrees Celsius.
At the poles of Mars, even carbon dioxide freezes at such low temperatures. Dry ice forms thick ice sheets at the poles of Mars, just like icebergs at the North and South poles of Earth. These natural conditions constitute a unique climatic environment on Mars.
The US “Mars Millennial Transformation” plan
The “Mars Millennial Transformation” plan is divided into six main stages:
1. astronauts must land firston Mars; a series of multi-year investigation and exploration missions to Mars. During each manned Mars landing mission, astronauts will establish a small living base on Mars.
2. In about 100 years, scientists will use various methods to release frozen carbon dioxide in Mars' soil to "warm the planet." About 3 billion years ago, the surface of Mars was surrounded by a thick atmosphere of carbon dioxide. However, as Mars cooled, most of the carbon dioxide was absorbed and frozen by the ground. Mars will gradually form an atmosphere as carbon dioxide frozen in Martian soil and polar ice caps is gradually released into the air.
3. After 200 years, when Mars gradually warms and the carbon dioxide released from the surface of Mars will be sufficient to form a certain atmospheric pressure.than on Mars, then liquid water will flow on the surface of Mars. and water will begin to form and Mars will experience weather phenomena such as rain and snow. Humans can bring bacteria and moss that survived in Antarctica's extreme climate to Mars. Microorganisms, algae and bryophytes can all survive on Martian rocks.
4. In 600 years, when microorganisms create enough organic soil on the surface of Mars and release a certain amount of oxygen into the atmosphere, humans will be able to transplant flowering plants, conifers or temperate plants. the surface of Mars. Lin could eventually take root on Mars. Plant growth means Mars will produce more oxygen and photosynthesis will turn more and more carbon dioxide into oxygen.
5. In 900 years, humans will be able to build colonies on Mars. Power stationsNuclear and wind power plants will be established on Mars to provide a continuous supply of energy to Martian colonies.
6. In about 1,000 years, humans will be able to immigrate to Mars, and there will be many enclosed cities with domes on Mars. At present, the average temperature at the equator of Mars has reached 4 degrees Celsius, and the Martian atmosphere will contain 50% carbon dioxide, 40% nitrogen, 5% oxygen and 5% others gas.
However, since the oxygen content on Mars will still be very low, so when the "Martians" walk on the surface of Mars, they still have to wear oxygen masks like when they dive underwater.
The temperature of the flame is usually only a few hundred degrees, but why can it heat objects to thousands of degrees? Can't the temperature just go from low to high?
StaffI think it's possible in theory, but if you want to implement it, you need solid technology.
There is a lot of thermal energy stored on the ball, and volcanic lava is one of the manifestations. There is a lot of lava beneath the Earth's surface, which reminds us why not use the energy released by volcanoes to generate electricity?
Part of the volcano is still active today and you can see bubbling mud pools, geothermal hot springs and numerous steam vents. Locals use volcanic steam for washing clothes and bathing, but these resources have greater development value. There are heat currents surging underground onto the active surface of the earth, and the temperature can reach 300 to 400 degrees Celsius. Going deeper, it would be possible to use this high temperature steam to enterbuild large turbines and produce large quantities of electricity.
A survey by physicists shows that a volcano can generate one billion watts of electricity, making the development of geothermal energy gradually attracting people's attention. One gigawatt is equivalent to the electricity production capacity of millions of solar panels or 500 wind turbines. The total energy available for the development of a volcano is estimated at around 10 GW.
A few years ago, the Ethiopians launched a pilot project for geothermal energy production in the Aruto volcanic area. They are now upgrading the power plant infrastructure and it is expected that electricity production will continue. increase tenfold, from 7 MW to 70 MW. Overall, it appears that geothermal energy development will provide an excellent low-carbon renewable energy solution for Ethiopia. Laissed geothermal energy production to lead the entire electricity sector and help local people escape poverty. It's not that simple. Working around lava is easier said than done, and all tools must withstand the extreme conditions. A fact-finding organization formed by a consortium of Ethiopian universities to study these questions. Researchers are focusing on risk prevention and methods for developing and detecting volcanoes so that volcanic energy can be harnessed safely and sustainably.
The temperature of the flame is only a few hundred degrees because the heat is dissipated into the air, and the hot air will rise quickly and carry away the heat. Therefore, the flame temperature will not be too high when heating other objects because the objects are solid. Heat builds up on objects and continues to increase. The principleof gas welding is to allow the fuel gas to burn quickly to accumulate a large amount of heat in a short time. In short, the temperature is high. The degree to which it can be heated has nothing to do with the fuel, only the burning rate and heat dissipation conditions.
