Tesla vehicles are equipped with extrernal speakers.
The main function is to output a pedestrian warning sound, which has become required for electric vehicles in many markets due to the fact that they are quiet at low speeds.
Tesla CEO Elon Musk has been playing around with ideas on how to release other features that take advantage of the fact that the vehicles are now equipped with external speakers.
Air conditioners are a convenient way to cool down offices and homes, but they use huge amounts of energy in the process. A team of scientists has been developing an alternative solution for those warm summer months called the Cold Tube, which works by absorbing body heat emitted from a person and can use around half the energy of traditional systems as a result.
The notoriously bad energy efficiency of air conditioners has motivated the development a range of environmentally friendly solutions, from attachments that use water mist to pre-cool the units to solar-powered systems that produce hot water at the same time. In 2018, Richard Branson even launched a US$3 million competition aimed at developing more energy efficient air conditioners.
Similarly, the research team behind the Cold Tube has been investigating next-generation systems that keep people cool in more efficient ways. Made up of scientists from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre, the team took aim at the dehumidification process that is a critical function of today’s air conditioning systems.

The waste fibres from hemp crops can be transformed into high-performance energy storage devices, scientists say.
They “cooked” cannabis bark into carbon nanosheets and built supercapacitors “on a par with or better than graphene” — the industry gold standard.
Electric cars and power tools could harness this hemp technology, the US researchers say.
First and foremost, I would likd to reiterate that Elon Musk is not motivated by money. Elon Musk uses his wealth to make a difference to mankind. Yes he makes billions (and deservedly) but he invests his billions for other projects too. From Tesla to Neuralink; from Starlink to The Boring Company. And for me the ever exciting SpaceX. My only wish is I live long enough to witness his many inventions and projects.
Four months ago when I did the video below and predicted that Elon Musk would be the World’s First Trillionaire, most people laughed and ridiculed the video especially as at that time Elon was only the 35th Richest Man in the World with a net worth of around the $30 Billion mark.
Fast forward four months later, Elon has added another £57.2 Billion to his net worth. And from 35th to 4th richest person in the world.
Imagine being the world’s first Trillionaire overcoming Jeff Bezos. What further projects will Elon do to advance the development of mankind. I for one, can’t wait.
Elon Musk has led Tesla to successfully pioneered the electric car. Will Tesla also propel Elon Musk as a potential candidate for the position of the world’s first trillionaire.
It might seem like a stretch, with Elon Musk’s current net worth of $29.6 billion and so many competitors ahead of him, but it’s for the future potential of his countless projects that some believe he has a fighting chance at taking the title.
If Tesla continued to grow rapidly, how much would it have to grow for Elon to have a shot at the trillion dollar mark? That question brings us to his 2018 compensation plan. When the details of the new payment plan got out to the media, it caused a bit of a stir. It was called the largest executive compensation deal in history and thought to be able to make him the richest man on the planet. But not without reaching a couple of insane milestones first. Under the plan, Elon would have to raise Tesla’s value to $100 billion first, with each milestone being $50 billion higher – all the way up to $650 billion. This would mean increasing the company’s value 11-fold, making Tesla into one of the five biggest US companies – and all of this by 2028. Even though Tesla recently did reach over $100 billion before dropping slightly below it, the plan can still be considered ridiculously ambitious. But even if it were realised and Tesla reached the $650 billion mark, with Elon Musk’s stake then amounting to 28.3% in best case scenario, his net worth would only reach $184 billion. This could still easily make him the richest man in the world, but far below a trillion dollars in net worth.
So, the only way that it would be even possible for Elon to reach that number would be for not only Tesla, but all of his other ventures to do extremely well.

Have you ever spilled your coffee on your desk? You may then have observed one of the most puzzling phenomena of fluid mechanics—the coffee ring effect. This effect has hindered the industrial deployment of functional inks with graphene, 2-D materials, and nanoparticles because it makes printed electronic devices behave irregularly.
Now, after studying this process for years, a team of researchers have created a new family of inks that overcomes this problem, enabling the fabrication of new electronics such as sensors, light detectors, batteries and solar cells.
Coffee rings form because the liquid evaporates quicker at the edges, causing an accumulation of solid particles that results in the characteristic dark ring. Inks behave like coffee—particles in the ink accumulate around the edges creating irregular shapes and uneven surfaces, especially when printing on hard surfaces like silicon wafers or plastics.

Getting rare materials from the ground into your phone is ugly. The mining industry is responsible for air and water pollution and the destruction of entire landscapes. But what if we could replace the mining industry on Earth with a clean process that can’t harm anyone? Well, we can. All we need to do is look up.

Building a factory is, unsurprisingly, a complex and long, drawn-out process. With Giga Shanghai, however, Tesla totally upended this assumption. The company achieved unprecedented speed of construction, through an efficient planning process, flexibility, and the ability to instantly learn from mistakes.
While Giga Shanghai was built in just 11 months, Tesla’s factory in Berlin will almost certainly break that record. On August 14, Tesmanian reported on the rapid progress at the site. Yet, in just the few days since, the Giga Berlin construction team made another breakthrough.
Munich’s Sono Motors are about to launch the first mass-produced solar powered car in the world, the Sion, with solar panels all over it.
As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO2 molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way to fine-tune a copper catalyst to produce complex hydrocarbons—known as C2-plus products—from CO2 with remarkable efficiency.
In a study published in Nature Communications, the researchers report a catalyst that can produce C2-plus compounds with up to 72% faradaic efficiency (a measure of how efficiently electrical energy is used to convert carbon dioxide into chemical reaction products). That’s far better than the reported efficiencies of other catalysts for C2-plus reactions, the researchers say. And the preparation process can be scaled up to an industrial level fairly easily, which gives the new catalyst potential for use in large-scale CO2 recycling efforts.
“There had been reports in the literature of all kinds of different treatments for copper that could produce these C2-plus with a range of different efficiencies,” said Tayhas Palmore, the a professor of engineering at Brown who co-authored the paper with Ph.D. student Taehee Kim. “What Taehee did was a set of experiments to unravel what each of these treatment steps was actually doing to the catalyst in terms of reactivity, which pointed the way to optimizing a catalyst for these multi-carbon compounds.”
