The Tesla chief’s tweets about his homes come only a week after news outlet ProPublica reported that billionaires like Musk, along with Amazon’s Jeff Bezos and Berkshire Hathway CEO Warren Buffett paid little income tax relative to their outsize wealth.
Morocco-born Dr Rachid Yazami has lived all over the world, thanks to an invention he made in his first year as a PhD student – the graphite anode – which is one of the key components that make lithium-ion batteries perform so well.
With electric vehicles on the rise, he believes the invention will soon take you everywhere, too.
Yazami’s story starts in the mid-1970s when scientists knew that graphite could help to form molten or powdered lithium into a usable energy storage material but struggled to turn it into a product. In 1983 Yazami and co-author Ph. Touzain cracked the problem by using a solid polymer electrolyte.
Tesla’s NEW Giga Press Is a BIG Game Changer Tesla and big things are inseparable. Be it ambition, idea, or more tangible items, Tesla would rather go big. Perhaps that is due to the many successes the company has racked up in the short time it has existed or just the personality of the CEO, Elon Musk. Whatever the case, Tesla tends to come along and fundamentally change how things are done, just like with its Giga Press. What is a Giga Press and how does it work? Why is it a game changer in the auto making business? Welcome to Tech Archives.
What is a Giga Press?
They are giant machines made by IDRA Group based out in Italy. The name was actually coined by IDRA, not Tesla. Their purpose is die casting large parts in a single piece. If you have a head for figures, Giga Presses produce a clamping forces of between 55000 kilonewtons and 61000 kilonewtons. Giga Presses are the biggest casting machines to ever exist. To get a sense of how massive these machines are, they weigh 410 to 430 tonnes. That is the equivalent of five Space Shuttles. They are the sizes of houses, at 20 meters by 7.5 meters by 6 meters and require dozens of flatbed trucks for transportation. And to get a sense of what a Giga Press does, think of a small plastic toy car. You would notice the chassis is made from a single piece. That is what a Tesla Giga Press tries to achieve. Instead of a chassis that uses up to 70 bolted and welded parts as it is done by all other car makers, the new Tesla chassis will be one solid piece of engineering feat.

Rare-earth metals and other minerals are essential for green tech like EVs and renewable energy. Trouble is, we need a lot of them and their availability on Earth is limited. But what if we could tap into all the materials flying around in space? Some scientists claim we could mine asteroids in the future. Yes, asteroids. Is it just an Armageddon remake or will we eventually…dig into them…?

Norway’s Wind Catching Systems (WCS) has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world’s biggest single turbines – while reducing costs enough to be immediately competitive with grid prices.
Standing more than 1000 ft (324 m) high, these mammoth Windcatcher grids would deploy multiple smaller turbines (no less than 117 in the render images) in a staggered formation atop a floating platform moored to the ocean floor using established practices from the oil and gas industry.
Just one of these arrays, says WCS, could offer double the swept area of the world’s biggest conventional wind turbines – the 15 MW Vestas V236 – and its smaller rotors could perform much better in wind speeds over 40 to 43 km/h (25 to 27 mph), when larger turbines tend to start pitching their blades to limit production and protect themselves from damage. The overall effect, says WCS, is a 500 percent boost in annual energy output, with each array making enough power to run 80000 European homes.
BMW Motorrad may not have arrived very early to the electric motorcycle party, but the company is making up for it now with what could become an industry first electric motorcycle with a driveshaft.
BMW loves its driveshaft motorcycles, but the electric motorcycle industry hasn’t been as keen on them.
Electric motors and batteries have freed motorcycle manufacturers from the typical design constraints of gas-powered drivetrains. Unshackled from traditional gas tanks and bulky internal combustion engines, designers have been granted unprecedented levels of freedom thanks to the modularity of electric motorcycle components.

(Bloomberg) — On a Wednesday afternoon in May, an Uber driver in San Francisco was about to run out of charge on his Nissan Leaf. Normally this would mean finding a place to plug in and wait for a half hour, at least. But this Leaf was different.
Instead of plugging in, the driver pulled into a swapping station near Mission Bay, where a set of robot arms lifted the car off of the ground, unloaded the depleted batteries and replaced them with a fully charged set. Twelve minutes later the Leaf pulled away with 32 kilowatt hours of energy, enough to drive about 130 miles, for a cost of $13.
A swap like this is a rare event in the U.S. The Leaf’s replaceable battery is made by Ample, one of the only companies offering a service that’s more popular in markets in Asia. In March, Ample announced that it had deployed five stations around the Bay Area. Nearly 100 Uber drivers are using them, the company says, making an average of 1.3 swaps per day. Ample’s operation is tiny compared to the 100000 public EV chargers in the U.S.—not to mention the 150000 gas stations running more than a million nozzles. Yet Ample’s founders Khaled Hassounah and John de Souza are convinced that it’s only a matter of time before the U.S. discovers that swapping is a necessary part of the transition to electric vehicles.
Using the full system, farmers could reduce costs by 40% and chemical usage by up to 95%.
Small Robot Company (SRC), a British agritech startup for sustainable farming, has developed AI-enabled robots – named Tom, Dick and Harry – that identify and kill individual weeds with electricity. These agricultural robots could reduce the use of harmful chemicals and heavy machinery, paving the way for a new approach to sustainable crop farming.
The startup has been working on automated weed killers since 2017, and this April officially launched Tom, the first commercial robot currently operating on three UK farms. Dick is still in the prototype phase, and Harry is still in development.
Small Robot company says the robot Tom is capable of scanning around 20 Hectares per day, collecting about six terabytes of data in an 8-hour shift to identify the crops, spots undesirable weeds – using “Wilma,” an artificial intelligence operating system. This data can then be sent to Dick – the world’s first non-chemical robotic weeding system that zaps individual weeds with electrical ‘lightning strikes.’ And finally, Harry plants seeds in the weed-free soil.
