Waymo, Google self-driving cars test-driving on public roads, without anyone in the driver’s seat
Опубликовано: 7 нояб. 2017 г.[video and following text by Waymo]
-----------------------------------
Waymo, which started as the Google self-driving car project in 2009, is ready for the next phase. Starting now, Waymo’s fully self-driving vehicles — the most advanced self-driving vehicles on the road today — are test-driving on public roads, without anyone in the driver’s seat. And soon, members of the public will get to use these vehicles in their daily lives.
After more than eight years of testing and development, we're ready to unlock the potential of fully self-driving technology, so we can make it easier and safer for everyone to get around.
Опубликовано: 23 дек. 2019 г.The Tesla Roadster is billed as The quickest car in the world, with record-setting acceleration, range and performance this all electric vehicle is entering serious hypercar territory. The disclosed specs are impressive, and the design blends aerodynamic efficiency with smooth flowing lines in a way that excites that primal instinct in all car enthusiasts. At a retail price of $200,000, this high tech marvel is a great value, if you have 200 grand lying around to blow on a sports car.
The most publicized feature of the #Tesla Roadster is certainly its head snapping acceleration, this extremely swift electric super car going from 0 to 60 miles per hour in just 1.9 seconds. This incredible feat is even more impressive than the the acceleration of the $354,000 Lamborghini Murcielago, for example, which can achieve 0-60 in 3.1 seconds, 1.2 seconds slower than the Roadster. Another super car that has slower acceleration than Elon Musk’s EV is the famous Bugatti Chiron, a 3-million-dollar vehicle that can accelerate from 0 to 60 in only 2.4 seconds. It’s claimed the Roadsters ¼ mile time will be under 9 seconds with a top speed of 250 mph. If we’re counting the Chiron does a quarter mile in 9.9 seconds.
Tesla Roaster vs Bugatti Chiron
In fact, the Roadster’s specifications beat the Chiron in almost every category, the single feature where the Bugatti excels being its top speed, which maxes out at 261 miles per hour, 11 miles per hour faster than the Roadster. But…you can buy fifteen all electric Tesla Roadsters for the price of one Chiron.
The special Space X model of the Roadster is rumored to come equipped with thrusters, a technical feature that many first thought was one of Elon’s notorious goofs, but Musk confirmed that a special edition of the car will come equipped with “small rocket thrusters” Technically “composite overwrapped pressure vessel” (COPV), basically high pressure jets that will help the car accelerate, decelerate and even provide additional downforce to improve traction. The air will be compressed by electric pumps powered by the roadsters battery keeping the car “All Electric” We’re not exactly sure what this system will look like in a production implementation, but the 10 estimated thrusters are definitely a feature that no other super car can compete with.
Limited range is one of the biggest concerns drivers have about electric vehicles, In fact there’s even an industry term coined “Range Anxiety”, the Roadster with it’s Hefty battery pack is the right medicine to cure range anxiety, with an estimated range of 620 miles on single charge, it beats every other comparable supercar, the $310,000 Aston Martin DBS Superleggera with its twin-turbocharged 5.2-liter V-12 715 horsepower engine couldn’t even cover half that distance on a full tank of gas. A feature that’s actually important to certain high-end customers that participate in long distance motor rally’s like the Gumball 3000. The anticipated 200 kWh battery of the roadster has twice the capacity of the Tesla Model S P100D.
Now if we want to talk economics, The Tesla Roadster is going to be limited to 10,000 models per year, making this all electric supercar a scarce resource. As we all know the law of supply and demand dictates price, and with only 10,000 models being produced per year, the Roadster will practically be a collectors item. By comparison Porsche produced 36,236 911’s in 2018 and on average 135,000 people peform a google search about the Porsche 911 every month, while the Tesla Roadster garners 165,000 monthly searches. With this kind of interest and the limited supply, we expect there might just be a lucrative aftermarket for the Roadster.
In case you didn’t know, the Roadster has the automotive world abuzz regarding it’s incredible torque, this incredible electric vehicle being expected to have 7,376 pound-feet or 10,000 newton-meters of wheel torque.
To handle this massive force, the Roadster comes standard in all wheel drive and is equipped with torque vectoring technology. The torque is intelligently and dynamically applied to each wheel, improving handling and increasing efficiency of power transfer making the Tesla a very stable car on the road. Tesla’s software is expected to be a more advanced and evolved system than most combustion super cars.
All the Tesla models are brilliantly engineered and have stellar designs, and the Roadster really takes the prize with its topnotch performance and from what we’ve heard from the chief designer Franz von Holzhausen, the upcoming production model will be even more powerful than the concept that was presented and marketed until now. He claims the roadster is evolving and inching towards perfection

Winsun 3D R&D Center in Shanghai — Largest 3D Printing Building Construction
Опубликовано: 28 окт. 2019 г.The video shows the ongoing erection of the 3D R&D Center, which is the largest 3D printed construction in the world. It consists of 7 large buildings. The buildings are printed and build with 9-12 workers, 3 machines: excavator, one crane, and 1 large 3D printer.
It shows the 3D printed walls with 2 different patterns: On 1 side the weaving decorative pattern, on the other side the layer-by-layer pattern.
Technological development of the green recycling industry incorporated in 3D printing construction, and technology that allows for zero waste construction. Winsun proposes the concept of the 'Green Recycling Industry' with 3D printed buildings. The strengths and output (including Waste) of several industries can be combined, such as urban construction, steel mill (waste: steel slack), power plant (waste: coal ash), chemical industry, locally available building materials, such as sand, etc.
The 3D printed products, such as 3D printing Ink, 3D printed walls and modules, are all technically assessed by Shanghai Research Institution of Buildings Science (SRIBS) and local and international standards were applied. This is a very important step into Standardization of the 3D printing technology.
Winsuns' technology goes much further than just replacing the conventional way of 'Construction'. You can see all these advantages allow for a new, greener ecological society. It can realize zero garbage communities, ecological agriculture, etc. It provides new functions for our conventional way of living and waste disposal.
Join us in the dream for future cities. Let's build our low carbon emission, recyclable and vibrant home together!
