In 1882, Nikola Tesla identified the concept of the rotating magnetic field. In 1885, Galileo Ferraris independently researched the concept. In 1888, Tesla gained U.S. Patent 381,968 for his work.

The IRENA report found that solar and onshore wind are the cheapest energy sources. It states that in 2017 wind turbine prices had an average cost of $0.06 per kWh, and at times dropped to $0.04 per kWh. In comparison, electricity produced by fossil fuels typically ran from $0.05 to $0.17 per kWh.

A vacuum cleaner can use magnets to separate out metallic objects before they do any damage. Strictly speaking, all vacuum cleaners use magnets. Magnets are crucial to the electric motors that create the cleaner’s suction.

Does a compass work on the Moon? On Earth, a compass needle points to the North Magnetic pole. But on the Moon, Mr. Dietrich said, ”there is no magnetic field that would be detectable by your average Earth compass.

NASA recently announced that – for the first time – we’ve confirmed the water molecule, H2O, in sunlit areas of the Moon. This indicates that water is widely distributed across the lunar surface.

As magnetic field lines cannot pass through electrically conductive objects (such as Mars), they drape themselves around the planet creating a magnetosphere, even if the planet does not necessarily have a global magnetic field. The outer boundary of the planet’s magnetic field is called ‘bow shock’.

Mars does have an atmosphere, but it is about 100 times thinner than Earth’s atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.

Its atmosphere is rich in carbon dioxide (over 96%) and it is very dense. The atmosphere of Mars is also rich in carbon dioxide (above 96%), but it is extremely thin (1% of Earth’s atmosphere), very dry and located further away from the Sun. This combination makes the planet an incredibly cold place.

Yes, we can, plant trees on Mars. Yes, doing this can produce oxygen there.

Earth

To support a starting population of a few hundred people on the moon, we’d have to start by transporting air to the lunar surface, pumping it into sealed structures in which humans would live. “People don’t use much air, and for a long time, we will not need to make the air on the moon.

Tough Place to Live No evidence for life has been found on Mercury. Daytime Temperatures can reach 430 degrees Celsius (800 degrees Fahrenheit) and drop to -180 degrees Celsius (-290 degrees Fahrenheit) at night. It is unlikely life (as we know it) could survive on this planet.

All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’.

the Blue Planet

The word sun comes from the Old English word sunne, which itself comes from the older Proto-Germanic language’s word sunnōn. In ancient times the Sun was widely seen as a god, and the name for Sun was the name of that god. Ancient Greeks called the Sun Helios, and this word is still used to describe the Sun today.
