Tesla’s solar roof is gradually rolling out to more homes. A new set of photos shared this week show a new installation at twilight, complete with cutouts for chimneys and other features. The design looks impressive, and it’s one of the few sightings seen on social media since the first installations appeared early last year.
The roof was shared by a now-deleted Twitter account, which was subsequently posted to Reddit by a user called “Potatochak,” where it received over 3,000 upvotes on the Tesla subreddit. The depicted tiles appear to be the textured variety, but the company also offers a smooth style depending on cosmetic appearance. Tesla recommends a normal house uses a mix of 35 percent solar tiles at $42 per square foot to 65 percent “dummy” tiles at $11 per square foot, resulting in an average price of $21.85 per square foot, but it’s unclear how many times are operational in these images.
A pilot project to turn 10 homes in Nottingham into net-zero emission properties without residents even moving out is nearing completion.
Developer Melius Homes and social landlord Nottingham City Homes have worked together on the scheme, with UK solar manufacturer Viridian Solar providing photovoltaic roofing.
The upgrades also include better insulated outside walls and upgraded heating systems.
After the refurbishment, tenants will pay an energy services fee instead of paying for gas and electricity.
With this guaranteed additional income, to which savings on planned maintenance costs are added, the landlord can borrow enough money to fund the upfront costs.
The goal is to drive better economies of scale so the work can be completed at an attractive price requiring no government support.
Stuart Elmes, CEO of Viridian Solar, said: “The opportunity it offers to completely regenerate whole areas of our towns and cities, increasing the value of property and improving the comfort of tenants, all financed by energy savings is amazing.”
The 10 homes in Nottingham are a pilot study, with an option to extend the programme to 400 more.
As posted in the MIT Technology Review earlier this year, we are developing a new “hot solar cell” technology.
By converting heat to focused beams of light, a new solar device could create cheap and continuous power.
Solar panels cover a growing number of rooftops, but even decades after they were first developed, the slabs of silicon remain bulky, expensive, and inefficient. Fundamental limitations prevent these conventional photovoltaics from absorbing more than a fraction of the energy in sunlight.
But a team of MIT scientists has built a different sort of solar energy device that uses inventive engineering and advances in materials science to capture far more of the sun’s energy. The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use. While various researchers have been working for years on so-called solar thermophotovoltaics, the MIT device is the first one to absorb more energy than its photovoltaic cell alone, demonstrating that the approach could dramatically increase efficiency.
Founded by Richard Hardiman, Ranmarine Technology uses WasteShark — 24-hour on-the-water drones. The solar-powered drones collect detritus, marine waste and chemical substances from ports and canals.
Founded in 2015 in South Africa, the company was later re-incorporated in the Netherlands at the start of last year as RanMarine Technology BV.
Hardiman is based in Rotterdam. He moved there after being selected for PortXL Rotterdam’s maritime accelerator (portxl.org) in February last year. The startup was one of 12 companies selected from 1000 startups worldwide.
In July last year the startup began a pilot with the Port of Rotterdam to test both the use of autonomous surface vessels in their waters and how the product actually works in “high trafficked waters”. The pilot was successfully completed last month.
There are currently 3 different types of the Waste Shark products: the WasteShark, the Great WasteShark and the ChemShark.

India’s first solar-powered trains has begun service, running a 12.5-mile route from Delhi’s Safdarjung station to Farukh Nagar in the country’s north. The diesel-electric hybrid train has six coach cars with solar panels embedded in their roofs. The panels feed a battery that can power the train for up to 72 hours. Roughly 50 solar-harvesting coaches are set to be launched in the next several days, running primarily along commuter routes.
The new trains are a part of Indian Railways’s plan to establish an energy-generation capacity of 1 gigawatt of solar and 130 megawatts of wind power in the next five years. The state-owned company has been using train-mounted solar panels since 2015 to power interior lights and air conditioning, but their newest train is the first in the world to use solar power. Although some people may be concerned about Warranty And Battery Life of these new trains. However, they have proven to be rather reliable.
India isn’t the only country exploring solar-powered trains. A research team at the Imperial College London is embarking on a similar quest to take trains off-grid and power them with solar energy. However, the UK project is looking to track-side solar panels, not ones directly mounted to the trains themselves.

Meet “Wave Star” of Denmark. It is a facility designed to convert kinetic wave power into electricity.
Wave Star is equipped with kinetic-energy harvesters called “floats.” The floats move up and down with the kinetic motion of the waves. The motion of the floats is transferred via hydraulics to rotate power generators. Their facility enables continuous energy production and a smooth output.
The full scale device will be equipped 20 floats of 10 m (33 ft) in diameter. Each power station will be able to produce 6 megawatts of energy, a single machine providing enough energy for roughly 4000 homes.
In the event of a storm, the floats can be lifted to a safe position. The facility could also be upgraded to utilize wind and solar power. The power stations are planned to hit the market this year!
We can now fold up solar panels that are nearly unbreakable and take them with us anywhere.
Instead of one solid sheet, these highly portable panels are made from a pliable network of glitter-sized solar cells.
A typical solar panel—more than five feet long and encased in glass—isn’t exactly portable. But a new type of solar technology, miniaturized so that each cell is the size of a piece of glitter, could be used anywhere. Solar panels are becoming increasingly popular in today’s society and they have some fantastic benefits. If you want to get some solar panels installed or just want to find out a little more about them, visit www.gienergy.com.au!
The tiny cells are made from high-efficiency silicon, like standard solar panels. But the new form means that they’re not only small but flexible, and can be folded up for transportation, incorporated into clothing, or easily used in electronics.
Conventional solar panels “are brittle because they’re crystalline,” Murat Okandan, CEO of mPower Technology, the startup making the new technology, tells Co.Exist. “If you bend or flex them, at some point they’ll just break and shatter. By making our cells small and then interconnecting them we’re able to make them almost unbreakable.”
In a small northern town in France a road has opened which is paved with solar cells. The goal is to see if the highway can power the town, which has 3,400 residents. On the other hand, it still wasn’t cheap for them to build it. In order to fashion a single 1 kilometer lane it cost around 5 million euro. It is also not the most energy efficient way to harness solar energy because the panels are flat on the ground and not optimally oriented towards the sun throughout the day. Nevertheless, it is a way to generate clean energy from existing infrastructure. Its been said that the government hopes to expand the project to other roadways as well.
With advent of more effective solar cells we may see the price drop per kilometer of pavement bit by bit!
A team of students and faculty from the University of Virginia School of Engineering created a prototype design of a solar powered wheelchair with retractable panels inspired by the idea from a man with cerebral palsy from Turkey. Their goal was to create a prototype of a solar powered wheelchair with retractable panels for individuals with lower extremity or mobility disabilities, spinal cord injury, or cerebral palsy. The Solar Powered Team (SPT) created the prototype using a Shoprider 6Runner wheelchair. They built a structured frame around the base of the wheelchair to hold the solar panels. Three solar panels were attached to a convertible-like structure which rotates back behind the wheelchair.
Researchers at the University of Michigan have developed solar cells that are lighter than ever before, modeled after “kirigami,” the ancient Japanese art of paper cutting.
A team of engineers and an artist developed an array of small solar cells that can tilt within a larger panel, keeping their surfaces more perpendicular to the sun’s rays.
“The beauty of our design is, from the standpoint of the person who’s putting this panel up, nothing would really change,” said Max Shtein, associate professor of materials science and engineering. “But inside, it would be doing something remarkable on a tiny scale: the solar cell would split into tiny segments that would follow the position of the sun in unison.”
