“The Line” is Saudi Arabia’s bold vision for the future of civilization: an ultra-modern city designed to house 1 million people and be entirely pollution-free. ↠Subscribe: https://www.youtube.com/c/TerraMaterO...But there’s one problem – it’s in the middle of the desert. And cities require a lot of water.Enter the Solar Dome, a new desalination system built on existing technology. It’s supposed to be a low-cost, efficient, and carbon-neutral way of turning saltwater into fresh water. With water scarcity already threatening the Middle East, Saudi Arabia is the world leader in desalination, but the process does pose problems. We take a closer look at the environmental costs of desalination, and how new innovation like the Solar Dome is trying to tackle these issues.Thank you for watching, liking, and sharing!

On our way to an emissions-neutral future the use of solar energy is crucial. The problem: the space for photovoltaic systems is getting tight. We need land for food, for housing, to preserve biodiversity. So where to go with the solar cells?
Using the sun's abundant power could be the solution for people who cannot afford escalating electricity costs. Channelled through simple, curved dishes its' rays can cook food and boil water.
The world's first fully working "sand battery", which can store green power for months at a time, has been installed by Finnish researchers.The developers said this could solve the problem of year-round supply, a major issue for green energy.Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.Please subscribe HERE http://bit.ly/1rbfUog#Finland #BBCNews
Discussing the idea of sand for thermal energy storage of heat for months intended for household and greenhouse heating in cold climates that get a lot of sunshine. I discuss the idea of sand verses water for heat storage and look at the different instalation aspects like piping, insulation, and solar collection from parabolic troughs and concentrated solar.
