A complex and dynamic landscape with 3000 meter High Mountains of frozen water juice of frozen methane and possibly even volcanoes spewing ice and it has an atmosphere and its still not a planet even though it all gets the sun just like the remaining 8 planets know because the new definition of a planet includes a criterion that pluto does not fulfill. The i use as a planet has to quote clear the neighborhood around its orbit that means it sweeps up other material in the vicinity to become the dominant object in its orbital saw on. The earth has done that as have the other 7 planets in our solar system but pluto failed to make the grade. Way out there in the region of its orbit there are many other minor planets known. The trance neptunian objects some of them quite similar to pluto like the even more massive heiress it was discovered in 2005 and ultimately led to plutos downfall. Clue showdowns to feel the other 2 criteria for planets. That is all but star and has enough mass to take
And put. Our faraway solar system neighbor was a planet and then it wasnt what happened. But 1st lets take a look at our planets sun wind and water are almost inexhaustible sources of energy here on earth and we have the technology to tap into them were moving away from fossil fuels to Renewable Energies that much is clear but whats unclear is how to reliably store that energy. Its a problem that urgently needs solving as more and more of our electricity in the future will come from renewable sources. A swiss engineer has come up with an interesting concept. Petrecki has a vision he wants to build a gravity assisted battery to compensate for the fluctuating nature of solar and wind energy if it works itll be able to store millions of times more energy than a conventional household battery. Vision is a system for storing large amounts of energy so we can increase the sheriff energy is in the grid. Or right now its about 30 to 35 percent thats the limit because the sun doesnt shine const
Come from many of those sources. A Service Engineer has come up with an interesting concept. Andrea petrecki has a vision he wants to build a gravity assisted battery to compensate for the fluctuating nature of solar and wind energy if it works itll be able to store millions of times more energy than a conventional household that are e. Vision is a system for storing large amounts of energy so we can increase the sheriff of nubile energy is in the grid. Or right now its about 30 to 35 percent thats the limit because the sun doesnt shine constantly what we need is a more economical and efficient storage system that and this is what his batteries will look like towers 60 to 120 meters high made of hundreds of cement blocks built around the 6 armed crane when theres excess energy in the grid it will Power Electric motors which move the crane arms to lift and stack the 35 ton blocks. Now the battery is charged. When electricity is needed the blocks are let down again generators in the cran
The global success stories. And yet theres a widening gap between education standards across the world. Children in developing countries are around 100 years behind those of industrialized nations. So why is that . Well, many children in developing countries have to work outside of school. And Armed Conflicts can prevent them from attending school regularly. In wealthier countries, young people typically attend school for an average of 12 years. In developing countries, for just 6. 5 years. And there are differences within industrial nations themselves, too. A childs background too often determines their success at school. Poverty can be a huge obstacle when it comes to gaining a good education. Those who can, often spend a lot of money on their kids schooling. Parents spend around 90 billion euros worldwide on extra coaching every year. Partly because theyre afraid their kids wont otherwise make the grade. And so the gap widens. In china too, many parents and kids have one objective w
