A team of archaeologists from the University of Cincinnati has found that between about 2,200 and 1,000 years ago, the drinking water in this reservoir was filtered through a mixture of zeolite and coarse, sand-sized crystalline quartz. This filtration system is the oldest known example of water purification in the western hemisphere and the oldest known use of zeolite for decontaminating drinking water in the world.
Ultra high-res displays for gadgets and tv sets may be coming. đ
By expanding on existing designs for electrodes of ultra-thin solar panels, Stanford researchers and collaborators in Korea have developed a new architecture for OLEDâorganic light-emitting diodeâdisplays that could enable televisions, smartphones and virtual or augmented reality devices with resolutions of up to 10,000 pixels per inch (PPI). (For comparison, the resolutions of new smartphones are around 400 to 500 PPI.)
Such high-pixel-density displays will be able to provide stunning images with true-to-life detailâsomething that will be even more important for headset displays designed to sit just centimeters from our faces.
The advance is based on research by Stanford University materials scientist Mark Brongersma in collaboration with the Samsung Advanced Institute of Technology (SAIT). Brongersma was initially put on this research path because he wanted to create an ultra-thin solar panel design.
A mysterious startup reveals a groundbreaking solar energy achievement.
GE unveils its largest wind turbine prototype yet, a 13MW behemoth that stands 248 metres tall and destined for use in offshore wind farms.
Wind turbine manufacturer GE Renewable Energy has unveiled latest wind turbine prototype, an optimised version of its Halifax-X offshore wind turbine design that can deliver a massive 13MW of output.
It is the largest turbine that GE has produced, standing 248 metres tall, with 107 metre long blades and offers around double the generation capacity of most wind turbines currently deployed around the world.
GE said that a working version of the wind turbine, optimised for offshore projects, had been deployed and was currently undergoing a series of tests to satisfy the requirements for certification.
Tesla is arguing that thereâs actually no defect with its Model S/Model X suspension and that China is basically forcing an unnecessary recall.
Earlier today, we reported on Tesla recalling almost 30,000 Model S and Model X vehicles that were shipped to China over an alleged issue with its suspension.
As we stated in the report, there were a few things that were strange about this report â primarily the fact that it only affected Model S and Model X vehicles sent to China between 2013 and 2017 even though those vehicles were produced in the US, and Tesla used the same suspension as all other Model S and Model X produced during that period.
âWeâre not moving heat from the surface to the atmosphere. Weâre just dumping it all out into the universe, which is an infinite heat sink,â said Xiangyu Li, a postdoctoral researcher at the Massachusetts Institute of Technology who worked on this project as a Ph.D. student in Ruanâs lab.
WEST LAFAYETTE, Ind. â What if paint could cool off a building enough to not need air conditioning?
Purdue University engineers have created white paint that can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings â almost like a refrigerator does, but without consuming energy.
According to the researchers, the paint would replace the need for air conditioning by absorbing nearly no solar energy and sending heat away from the building. Without the building heating up, air conditioning wouldnât have to kick on.
(Reuters) â Indiaâs richest state Maharashtra has invited U.S. electric-car maker Tesla Inc, weeks after its Chief Executive Officer Elon Musk suggested entering the country next year.
In a tweet here on Thursday, state tourism and environment minister Aaditya Thackeray said he and industries minister Subhash Desai held a video call with Tesla executives earlier in the day to invite them to the state.
Earlier this month, Musk said âNext year for sureâ on Twitter in reply to a post with a photograph of a T-shirt with the message: âIndia wants Teslaâ.
Just a matter of time.
In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. Thatâs thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important these policies are to encouraging development of renewables and other environmentally forward technologies.
âïž You love renewable energy. So do we. Letâs nerd out over it together.
Tesla has dismissed Evan Horetsky, also known as âMister Gigaâ, the engineer behind Teslaâs construction projects and more recently leading Gigafactory Berlin construction, according to a German report.
Horetsky is a mechanical engineer who joined Tesla back in 2015 to work on the Gigafactory Nevada project.
He has since participated in most of Teslaâs construction projects around the world and most recently, he was put in charge of Teslaâs Gigafactory Berlin project.
