The purpose-built 35ft electric flying boat also offers a top speed of 22 knots.

How do you make an electric boat go faster and further on a single charge? Either you fit a more powerful battery that usually increases the weight, making it counterproductive, or use a hydrofoil system to reduce drag.

The SpiritBARTech35EF is a product of UK-based boat design… More.

SpiritBARTech35EF has found an ideal solution to this by utilizing both to derive the longest range for an electric yacht at 100 nautical miles (115 miles/185 km) and a top speed of 22 knots (25 mph/41 km/h) once it is flying. The purpose-built 35ft electric flying boat also features a trio of active retractable foils to help minimize drag.

Flying cars are becoming closer to reality than what sci-fi movies may lead you to believe. Another electric flying car “took flight” this week in the US. CEO Doron Merdinger of Miami-based Doroni Aerospace successfully piloted a two-seater personal vertical takeoff and landing (eVTOL) aircraft that fits in your garage.

Electric flying cars are all of a sudden taking the US by storm. Last month, California-based Alef Aeronautics revealed its 100% electric flying car, “Model A,” the first of its kind to receive legal approval to fly from the US government.

According to Alef, the Model A has a 200-mile driving range and can fly for 110 miles. The company says it had gathered over 440 orders for its $300K electric flying car within three months.

BENGALURU, July 13 (Reuters) — Tesla (TSLA.O) is discussing an investment proposal with the Indian government to set up a factory with an annual capacity to produce about half a million electric vehicles, the Times of India reported on Thursday, citing government sources.

The company, led by billionaire Elon Musk, is also looking at using India as an export base to ship cars to countries in the Indo-Pacific region, the report said.

The starting price for the vehicles will be 2 million rupees ($24,400.66), the report added, which is more than double of India’s cheapest EV, MG Comet, and half a million costlier than Tata Nexon EV, the top-selling electric car in the country.

A huge solar power station in China is generating clean energy, producing salt from sunlight, and serving as a shrimp-breeding site.

State-owned China Huadian Corporation said the 1-gigawatt (GW) Huadian Tianjin Haijing power station will generate 1.5 billion kilowatt-hours of electricity each year – enough to power around 1.5 million households in China.

The solar panels at the farm are bifacial, which means they benefit from both direct sun and sunlight that reflects from the water beneath.

The European Southern Observatory continues to build the largest telescope in the world, the Extremely Large Telescope (ELT). Construction of the telescope began in 2014 with flattening the top of a mountain named Cerro Armazones in Chile’s Atacama Desert.

ESO just announced that progress on construction has crossed the 50% mark. The remaining work should take another five years. When it finally comes online in 2028, the telescope will have a 39-meter (128 ft) primary mirror of 798 hexagonal segments, making it the largest telescope in the world for visible and infrared light. The new telescope should help to answer some of the outstanding questions about our Universe, such as how the first stars and galaxies formed, and perhaps even be able to take direct images of extrasolar planets.

“The ELT is the largest of the next generation of ground-based optical and near-infrared telescopes and the one that is most advanced in its construction,” said ESO Director General Xavier Barcons, in an ESO press release. “Reaching 50% completion is no small feat, given the challenges inherent to large, complex projects, and it was only possible thanks to the commitment of everyone at ESO, the continued support of the ESO Member States and the engagement of our partners in industry and instrument consortia. I am extremely proud that the ELT has reached this milestone.”

It will also reduce travel time to Saturn’s moon Titan to just two years.

Pulsar Fusion, a UK-based space firm, is building a nuclear fusion-based rocket engine that could exceed temperatures on the Sun. The construction of the largest-ever fusion rocket engine has begun, and its exhaust speeds could exceed 500,000 miles per hour.

Nuclear fusion has long been proposed to answer our energy and climate change woes as it promises a cleaner power source. Inspired by the Sun, scientists have been working to build nuclear fusion reactors and have succeeded in generating record-high temperatures but not more energy than they have put in.

Every now and then, revolutionary technology seems to spontaneously appear out of thin air and change our world. Dynamite, penicillin, X-ray machines, and even microwaves are all examples of such revolutionary accidental discoveries.

Well, this year we may have had yet another. However, this time it is set not only to revolutionise the way we live, but potentially save our planet from looming climate change by unlocking an elusive technology: lithium-sulfur batteries.

For decades, we have been searching for the best technology to power our modern lifestyle and enable clean technology, like electric cars. Since the early ‘90s, the battery technology of choice has been lithium-ion.

There’s a new way to harness the power of the sun and it may just revolutionize how we approach solar energy. The development is called quantum dots and it consists of tiny semiconductor particles only a few nanometers in size.

This is according to a report by Fagen Wasanni published on Saturday.

“Quantum dots have unique properties that make them ideal for use in solar cells. Their small size allows them to absorb light from a wide range of wavelengths, including those that traditional solar cells cannot capture. This means that quantum dot-based solar cells can potentially convert more sunlight into electricity, significantly increasing their efficiency,” states the report.

Touring, a type of riding that involves long distance trips, has long been the achilles heel of electric motorcycles. While e-motos have developed to the point where they can beat combustion engine motorcycles in nearly every other metric, quick recharging required for long distance riding has yet to reach parity with a gas station fill-up. At least, that was until Lightning Motorcycle debuted what it says is the fastest charging electric motorcycle yet.

Lightning Motorcycles, the Southern California-based boutique e-motorcycle manufacturer, claims that its new fast-charging electric motorcycle can recharge nearly as fast as a combustion engine motorcycle can refuel its tank.

Previously, the quickest DC fast-charging electric motorcycles like the models from Energica or Harley-Davidson’s LiveWire One boasted a recharge time of around 30 minutes for a nearly topped-up battery.

Silicon anode batteries have the potential to revolutionize energy storage capabilities, which is key to meeting climate goals and unlocking the full potential of electric vehicles.

However, the irreversible depletion of lithium ions in silicon anodes puts a major constraint on the development of next-generation lithium-ion batteries.

Scientists at Rice University’s George R. Brown School of Engineering have developed a readily scalable method to optimize prelithiation, a process that helps mitigate lithium loss and improves battery life cycles by coating silicon anodes with stabilized lithium metal particles (SLMPs).
