Revolutionizing Large-Scale Energy Storage: Better Multivalent Metal Batteries

Posted by in categories: computing, mobile phones, sustainability, transportation

They suggest next steps in search for large-scale energy storage solution.

Lithium-ion batteries are recognized for their high energy density in everything from mobile phones to laptop computers and electric vehicles, but as the need for grid-scale energy storage and other applications becomes more pressing, researchers have sought less expensive and more readily available alternatives to lithium.

Batteries using more abundant multivalent metals could revolutionize energy storage. Researchers review the current state of multivalent metal-ion battery research and provide a roadmap for future work in Nature Energy, reporting that the top candidates – using magnesium, calcium, zinc and aluminum – all have great promise, but also steep challenges to meet practical demands.

Hybrid solar converter harvests both sunlight and heat at 85% efficiency

Posted by in categories: solar power, sustainability

Engineers have developed a new type of hybrid solar energy converter, which uses energy from the Sun to create both electricity and steam. The device reportedly has high efficiency and runs at low cost, allowing industry to make use of a wider spectrum of solar energy.

The most common way of collecting energy from the Sun is through photovoltaics. These solar cells produce electricity from sunlight, and they’re so simple that they’re built into everything from garden lights to the grid itself.

But it’s not the only way. Solar concentrators collect heat instead of light, focusing the Sun’s rays to heat up a contained fluid. This can then be used to generate electricity – say as steam turning a turbine – or more directly, to heat homes or for other industrial processes.

Elon Musk Teases “Indoor/Outdoor Rave Space” on Berlin Tesla Factory Roof

Posted by in categories: Elon Musk, space, sustainability

The concept isn’t entirely new. In March, Musk posted a poll on Twitter asking his gigantic following if they were interested in a “mega rave cave” below Giga Berlin. 90.2 percent responded with the option “hell yes!”

Musk has plenty of reasons to celebrate. His car company’s valuation sky-rocketed to a high of $1,760 on Monday as tens of thousands of new investors were pouring in from online brokerage Robinhood. The rocketing valuation also sets Musk up for yet another massive $1.8 billion payday.

At the same time, the construction of the manufacturing plant has hit several setbacks, with environmental protests concerning deforestation and worries over drinking water supplies leading to a German court ordering Tesla to cease construction, but lifting the freeze several weeks later.

France and Germany lap up electric cars as subsidies make them ‘almost free’

Posted by in categories: mobile phones, sustainability, transportation

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.

Seawater could provide nearly unlimited amounts of critical battery material

Posted by in categories: chemistry, energy, sustainability, transportation

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.

Elon Musk’s college pal: ‘When Elon gets into something, he develops just this different level of interest in it than other people’

Posted by in categories: Elon Musk, space travel, sustainability

Elon is unique.


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.

Ocean Power Plant Generates Energy From Waves — Unlimited Cheap Clean Electricity

Posted by in categories: energy, sustainability

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.
