太阳能技术又有重大突破 | 一周看点









The company, called Heliogen, claims that its focussed beams of light are able to create a solar oven reaching 1,000 degrees Celsius (1,832 degrees Fahrenheit), something that hasn’t been done before in a commercial setting. That means solar power could replace fossil fuels for a host of industrial jobs, not just providing electricity.


“The world has a limited window to dramatically reduce greenhouse gas emissions,” says Bill Gross, CEO and founder of Heliogen. “We’ve made great strides in deploying clean energy in our electricity system. But electricity accounts for less than a quarter of global energy demand.”

Heliogen公司首席执行官兼创始人Bill Gross说:“全球大幅降低温室气体排放的方法有限,我们在电力系统中对清洁能源的利用成效显著,但电力需求在全球能源需求中所占比例不到四分之一。”

“Heliogen represents a technological leap forward in addressing the other 75 percent of energy demand: the use of fossil fuels for industrial processes and transportation. With low-cost, ultra-high temperature process heat, we have an opportunity to make meaningful contributions to solving the climate crisis.”
















Announcing its decision not to renew Ubers license, in a press release posted on its site, the TfL said:


Uber has made a number of positive changes and improvements to its culture, leadership and systems in the period since the Chief Magistrate granted it a licence in June 2018. This includes interacting with TfL in a transparent and productive manner.

自从 2018年6月首席治安官为其颁发牌照以来,Uber在公司文化、领导和系统上做出了很多积极的改进,其中包括与伦敦交通局进行了透明高效的沟通。

However, TfL has identified a pattern of failures by the company including several breaches that placed passengers and their safety at risk.


Despite addressing some of these issues, TfL does not have confidence that similar issues will not reoccur in the future, which has led it to conclude that the company is not fit and proper at this time.


Its important to note that though TfL has decided not to renew Ubers license, Ubers will continue to be on the street in London for the time being.


Uber has 21 days to appeal the decision, during which time the service can continue operating.
















Mr. Sato arrived bright and early for Tapioca Land Cafe’s grand opening, expecting a swarm of reporters and news-copters swirling overhead, but was surprised to find only himself. It made him feel good though, as clearly no one loved tapioca as much as he did. This was proof of that.

Sato先生一大早就来到了Tapioca Land奶茶店的开业典礼上,他以为会看到一大群记者,还会有新闻直升机在空中盘旋,但他惊讶地发现只有他自己。他还是很开心的,因为显然别人对珍珠奶茶的喜爱程度都不及他,事实也证明如此。

It also meant he would be the first person in the world to taste of Tapioca Land Cafe’s offerings - a rare honor indeed!

这也意味着他会是全世界第一个品尝Tapioca Land奶茶店的奶茶的人,这确实是难得的荣誉!

“Da Hong Pao Tapioca Milk Tea - 10,000 yen (US$92)”


Mr. Sato’s heart jumped in his chest. This was why he had come to Topica Land Cafe. As the first customer, he felt it was both his duty and immense pleasure to purchase and drink this luxury tea.


It looked more like cafe au lait than regular bubble tea, and was generally a little disappointing in the visual stimulation department. It was nice and all, just not 10,000-yen nice.

















Obviously, there isnt one silver bullet solution to the plastic issue, says Sander Defruyt, who leads the New Plastics Economy initiative at the nonprofit Ellen MacArthur Foundation, which initially brought the companies together when the project began.

非营利性组织艾伦·麦克阿瑟基金会“新塑料经济”倡议的发起人Sander Defruyt说:“显然解决塑料问题没有万全之策”,在项目开始之初就是艾伦·麦克阿瑟基金会把各公司召集到一起的。

We need to start by eliminating the plastic we dont need. We need a lot of innovation shifting from single-use to reuse business models. But recycling is still one part of the problem, and [brands] realize that to make recycling work, we need to improve the way plastic waste is sorted in sorting centers.


By sorting more accurately, the final bales of material are more valuable, and the total amount of material that can be recycled increases.


The system can identify whether a bottle was used for food or something like shampoo - a crucial step that current systems cant accomplish but is necessary for food companies that want to buy recycled plastic to reuse in new packaging, as European regulations prohibit them from using recycled plastic that was originally for something other than food.
