This bubbly concept car protects more than the driver; its next-generation rubber exterior can save pedestrians, too.
Traditional metal panels are replaced with soft rubber, which absorbs the impact of a collision. The car is also a shapeshifter, meaning that the rubber panels move and flex, forming a more aerodynamic shape.
The futuristic concept was recently showcased at the Tokyo Motor Show, which also featured artificially intelligent cars and electric vehicles. But none as adorable as this rubbery car.
Big science meets applied engineering. CERN, renowned for smashing protons, culling antimatter and the like, has put its accelerating processes to use making and commercializing solar panels.
Car buyers in Europe can now get their hands on a brand-new electric vehicle for less than the typical cost of a mobile-phone contract. Thanks to newly generous subsidies, some are even free.
Shoppers have swarmed virtual showrooms in Germany and France — the region’s two largest passenger car markets — after their national governments boosted electric-vehicle incentives to stimulate demand. Their purchase subsidies are now among the most favorable in the world.
The state support is allowing Autohaus Koenig, a dealership chain with more than 50 locations across Germany, to advertise a lease for the battery-powered Renault Zoe that is entirely covered by subsidies. In the 20 days since it put the offer online, roughly 3,000 people have inquired and about 300 have signed contracts.
Choi and other researchers have also tried to use lithium-ion battery electrodes to pull lithium directly from seawater and brines without the need for first evaporating the water. Those electrodes consist of sandwichlike layered materials designed to trap and hold lithium ions as a battery charges. In seawater, a negative electrical voltage applied to a lithium-grabbing electrode pulls lithium ions into the electrode. But it also pulls in sodium, a chemically similar element that is about 100,000 times more abundant in seawater than lithium. If the two elements push their way into the electrode at the same rate, sodium almost completely crowds out the lithium.
Lithium is prized for rechargeables because it stores more energy by weight than other battery materials. Manufacturers use more than 160,000 tons of the material every year, a number expected to grow nearly 10-fold over the next decade. But lithium supplies are limited and concentrated in a handful of countries, where the metal is either mined or extracted from briny water.
Lithium’s scarcity has raised concerns that future shortages could cause battery prices to skyrocket and stymie the growth of electric vehicles and other lithium-dependent technologies such as Tesla Powerwalls, stationary batteries often used to store rooftop solar power.
Seawater could come to the rescue. The world’s oceans contain an estimated 180 billion tons of lithium. But it’s dilute, present at roughly 0.2 parts per million. Researchers have devised numerous filters and membranes to try to selectively extract lithium from seawater. But those efforts rely on evaporating away much of the water to concentrate the lithium, which requires extensive land use and time. To date such efforts have not proved economical.
At age 17, Elon Musk left his home in South Africa and moved to Canada, where he enrolled at Queen’s University in Kingston, Ontario. During his freshman-year in the fall of 1990, Musk befriended Navaid Farooq while living in the same dorm, according to the book “Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future,” by Ashlee Vance.
Farooq, a Canadian who grew up in Geneva, bonded with Musk over their backgrounds abroad and their interest in strategy games, according to the book. Living in such close quarters, Farooq learned a lot about Musk, including what Farooq sees as his defining trait.
“When Elon gets into something, he develops just this different level of interest in it than other people,” Farooq said in Vance’s book. “This is what differentiates Elon from the rest of humanity.”
Unlimited Clean Energy with The Wavestar machine. Harness the Power of Wave Energy with the World’s Strongest Wave Power Concept. Oceans cover more than 70% of Earth’s surface and ocean waves carry enormous power. By utilizing the largest source of untapped clean energy, it could supply a substantial part of the world’s electricity. Wave energy is more predictable compared to wind power, the waves come and go slowly and can be forecasted 24 hours ahead. Also the production continues 6–8 hours after the wind settles. This makes wave energy an ideal complement for wind turbines and could satisfy the continuously increasing demand for renewable energy in the grid.
The concept was invented by sailing enthusiasts Niels and Keld Hansen in 2000. The challenge was to create a regular output of energy from ocean swells and waves that are 5–10 seconds apart. This was achieved with a row of half-submerged buoys, which rise and fall in turn as the wave passes, forming the iconic part of Wavestar’s design. This allows energy to be continually produced despite waves being periodic.
The machine’s unique storm protection system, one of the many patented aspects of the design, guarantees the machine’s sea survivability and represents a real milestone in the development of wave energy machines. Wave energy will play a crucial role in securing our energy future, but only machines that can withstand the strongest storms will survive.
Environmental issues demand swift diversification to multiple renewable sources in order for us to fulfill our future energy needs. Wavestar will work in harmony with other clean energy methods to support the alternative energy movement and ensure a continuous supply of clean energy. Imagine what we can do together.

Tesla is scrapping plans for a bargain Model Y SUV because of its short range on a single charge, CEO Elon Musk said in a tweet over the weekend.
Earlier this year, the electric car maker began producing its pricier, dual-motor all-wheel drive version of the Model Y, which starts at $49,000.
Tesla had planned to roll out a cheaper version of the Model Y — expected to be priced under $40,000 — with a single engine, rear-wheel drive and smaller battery. But Musk tweeted that the range on that vehicle would have been “unacceptably low” at less than 250 miles on a single charge.
Chemists at the University of Wisconsin-Madison and their collaborators have created a highly efficient and long-lasting solar flow battery, a way to generate, store and redeliver renewable electricity from the sun in one device.
The new device is made of silicon solar cells combined with advanced solar materials integrated with optimally designed chemical components. The solar flow battery, made by the Song Jin lab in the UW-Madison chemistry department, achieved a new record efficiency of 20 percent. That bests most commercially available silicon solar cells used today and is 40 percent more efficient than the previous record holder for solar flow batteries, also developed by the Jin lab.
