[quick news] on July 23, 2018, solar energy technology made a major breakthrough: heat energy can be stored for 100 years, with cost reduced by 95%

A major breakthrough has been made in solar energy technology: it can store heat energy for 100 years and reduce the cost by 95% It is reported that a solar energy technology may produce energy cheaper than fossil fuel for the first time It is said that the technology will create solar cells that are 95% cheaper than the existing system, and each cell can power 11 homes The technology is based on a centralized solar thermal disk with a battery made of patented metal alloy and hydrogen on the back, which can convert the heat of the sun into electrical energy and store the heat energy for 100 years without any waste Http:// Corning's sixth generation of gorilla glass is officially released in Silicon Valley Compared with the fifth generation, the overall performance of the sixth generation of gorilla glass is improved by two times, with higher surface lamination stress At 1 It can withstand 15 drops at the height of meters and still ensure the integrity According to the survey, people drop their mobile phones 7 times a year on average, more than half of them fall from 1 meter or less height, so the sixth generation will bear multiple falls as the focus of promotion Https:// the U.S Department of Justice ruled that it is legal to share the design drawings of 3D printing guns online, according to foreign media reports The ruling of the U.S Department of justice in a case indicated that it is legal to share the design drawings of 3D printing guns online In this case, Cody Wilson, the founder of distributed defense license, filed a lawsuit against the U.S State Department to protect its legitimate rights and interests in carrying weapons Wilson's victory means that digital gun design documents will be uploaded to the Internet without any supervision Wilson will restart the website defcad.com on August 1 to host gun design drawings Http:// waste lead-acid batteries flow into the "black market" to intensify heavy metal pollution Reporters in Jiangsu, Guangdong, Ningxia and other places found that the lead-acid battery in the production and recycling process of pollution is not only repeated Especially in the recycling process, on the one hand, regular lead recycling enterprises are generally "hungry", on the other hand, a large number of waste batteries are flowing into the "black market" Industry insiders believe that there are serious hidden dangers of lead and acid pollution in the production and recovery of lead-acid batteries, and frequent pollution events aggravate heavy metal pollution Http:// Chinese scientists reveal the chemical mechanism of the formation of nanoparticle in Shanghai air pollution Recently, China's scientific research team has discovered and confirmed the ternary nucleation of sulfuric acid dimethylamine water in Shanghai's atmosphere for the first time, revealing the formation of nano-sized micro particles in Shanghai's air pollution, that is, the chemical mechanism of the formation of new atmospheric particles This provides new scientific evidence for the formulation of the policy of prevention and control of air particle pollution in China http://
