The concept aims to encourage public transportation in the city.

Ponti Design Studio revealed a concept design of an electric double-decker driverless tram to hit the roads of post-COVID Hong Kong. Dubbed Island.

The vehicle’s curved windows and see-through top let the sunshine in during the day, allowing passengers to enjoy the city view at night. According to the website, the interiors are sleek and comfortable, with charcoal gray walls, cushioned seats, wooden floors, and trims with a natural finish. Island won the 2020 GIDA Design Award.

The country plans to increase its installed renewable energy capacity to 25 GW by 2030.

Greece met its energy demands from only renewable sources of energy for a period of five hours on Friday, October 7, PV Tech.

Back in the U.S., the state of California has managed to reach this landmark milestone a couple of times this year. However, Greece’s achievement is remarkable as the region is also fighting off a self-imposed ban on using Russia-supplied gas, in the wake of the conflict in Ukraine.

Many investors and onlookers are wondering what the future of Tesla’s valuation will look like, especially knowing how the company could revolutionize the world with its products. From electric vehicles to sustainable energy, some have even made the case that Tesla could someday become the world’s largest company — likely shifting the way the world works either way.

Devising renewable sources of energy is a key concern for scientists, political leaders and communities as the world comes to terms with the realities of climate change and the limits of the Earth’s natural resources. In an exciting new development, scientists from the Institute of Scientific and Industrial Research (SANKEN) at Osaka University have demonstrated that electricity may be obtainable from water with a high salt concentration, such as seawater.

Some people think about “osmosis” as just a science term they were forced to learn in elementary school biology class. However, the spontaneous motion of dissolved ions or molecules through a semi-permeable membrane when there is a concentration difference between the two sides can be harnessed to generate electricity. And luckily for us, the oceans are filled with salty water, which may be used to help alleviate humanity’s ever-growing demand for energy. However, in order to be practical, this membrane needs to be very thin and highly selective to allow ions—but not water molecules—to pass through.

Now, a research team led by Osaka University has used conventional semiconductor processing technology to precisely control the structure and arrangement of nanopores in an ultrathin silicon membrane. Because these fabrication methods have been around for decades, the costs and design complexities were minimized. Moreover, the size and location of the pores could be precisely controlled.

The form gets rolled out on a concrete slab or other foundation, then inflated with an air pump; at this point, it may look a little like one of those bouncy houses you see at children’s parties. Then a ready mix truck shows up—these trucks can mix concrete on their way to a site or at the site itself—and pumps concrete into the form. The company’s website says they can use local ready mix concrete, aircrete (a lightweight version of concrete that incorporates air bubbles instead of traditional aggregate), sustainable cement, and other “pumpable building materials.”

The concrete-pumping step is a bit like 3D printing, though 3D printed homes use concrete as printer “ink” to put walls down layer by layer rather than spitting all the concrete into a form at once. This is even faster; Bell told New Atlas, “For our 100-square-foot and 200-square-foot prototypes, the inflation took 7 to 10 minutes with air. Then the concrete pump filled them in 1.5 hours.”

Once the concrete has dried, the form isn’t stripped away; it stays right where it is, serving as an airtight barrier for waterproofing and insulation. The final step is to add all the things that make a house look and function like a house rather than a giant clay art project, that is, a facade, windows, doors, drywall, HVAC, and plumbing.

Experimental technology used to cool equipment in space might soon be able to cut the charging times of electric vehicles to five minutes or less, American space agency NASA said this week.

The federal space agency-funded technology, in partnership with Purdue University, says the research they’re planning for future space missions shows its tech could charge an electric car within minutes instead of hours, according to an Oct. 5 blog by NASA.

Using a technique known as “subcooled flow boiling,” the tech could boost the amount of electrical current EV chargers by roughly 1,400 amps, nearly five times the rate of up to 520 amps currently supplied to EVs, NASA said.

A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today (Oct. 12) in the journal Nature.

“The need for smaller, faster-charging batteries is greater than ever,” said Chao-Yang Wang, the William E. Diefenderfer Professor of Mechanical Engineering at Penn State and lead author on the study. “There are simply not enough batteries and critical raw materials, especially those produced domestically, to meet anticipated demand.”

In August, California’s Air Resources Board passed an extensive plan to restrict and ultimately ban the sale of gasoline-powered cars within the state. By 2035, the largest auto market in the United States will effectively retire the internal combustion engine.

Greece was entirely powered by renewables for the first time in its history last week, according to the country’s independent power transmission operator (IPTO).

On Friday (7 October), for a period of around five hours, the country was running off entirely renewable power, reaching a record high of 3,106MWh at eight o’clock (GMT).

“For the first time in the history of the Greek electricity system, the demand was covered 100% from renewable energy sources,” its IPTO wrote.

Tesla has updated its in-car energy app to give a comparison between real energy use and the projected range, and it even gives you range advice to get closer to the optimal range.

Range calculations are difficult regardless of the type of powertrain – electric or internal combustion engine.

There are just so many factors that can affect the efficiency of a vehicle on a road that it is hard to determine how far it can go on a full battery pack or tank of gas.
