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.

The Drawdown EcoChallenge is a fun and social way to learn about and take action on the 100 climate solutions featured in the seminal work of Paul Hawken “Drawdown.”
From April 4-25, individuals and teams from around the world will take part in simple daily activities to reduce their carbon footprints and delve into the world’s most substantive solutions to global warming. At the end of the Challenge, the teams with the most points will win great prizes, including copies of Drawdown and a one-hour video session with Paul Hawken!
The EcoChallenges are broken down into these sections (with an added note of current participants):
LAND USE (1260)
ELECTRICITY GENERATION (1751)
WOMEN AND GIRLS (1392)
BUILDINGS AND CITIES (1598)
Executive Director of Drawdown, Hawken states “All of life is comprised of self-organizing systems and the Drawdown EcoChallenge is exactly that—people coming together to share, learn, support, imagine, and innovate for a better world. We are honored to be a part of this significant and brilliant initiative.”

Based out of the waterfront partnership of Baltimore, Maryland and going by the name “Professor & Mr. Trash Wheel” these devices are vacuuming plastic from our oceans much like a Roomba for waterways. They operate exclusively on the energy they get from sunlight and water. Collecting litter and debris, keeping trash from winding up in the ocean, the device uses two trash containment booms in order to direct the waste up a conveyor belt and into the dumpster barge on the other end.
Since being installed, the trash wheels have kept over one millions pounds of litter out of the Atlantic ocean!

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.

Combining Quebec’s expertise in hydroelectricity, aluminum and renewable energy, Idénergie has successfully developed the first solution to easily generate electricity from the natural flow of a river. This innovation will allow people to generate electricity from nearby rivers, 24 hours a day.
Idénergie’s river turbine has an embedded smart converter that allows the conversion of the energy harnessed from the water current into electricity. The built-in smart converter includes many additional features including a self-starting turbine, continuous power optimization, remote monitoring capabilities, an emergency brake and many more to come.
Mostly made of noble metals such as aluminium and other environmentally friendly components, the turbine is the greenest amongst all available renewable energy products. These material do not react to the environment and are easily recyclable ensuring a substantial end of life value. In addition, the river turbine does not require a permanent structure reducing its impact on aquatic fauna.
By taking into account numerous studies estimating the interactions of the turbines with the ecosystems, Idénergie designed its product in order for it to have minimal impact on the aquatic fauna and its housing environment. Studies carried out by the Alden laboratories, an american entity, have proven that the Darrieus Turbines, used by Idenergie, represent no harm to the river’s ecosystem. In fact, extracting energy from a fluid tend to slow it down, resulting in faster velocity on the side of the turbine thus floating objects and debris, as well as fish, tend to naturally avoid the turbine resulting in 98% survival rate.
A society based on a green economy is Idénergie’s dream. Fully aware of the need to adapt to the threat of climate change, they aim to make a positive difference by encouraging every individual, homeowner or community to use renewable energy and become energy-independent.
Check out their website http://idenergie.ca/en/ to see how this renewable-energy hardware is accessible and discover how yes, it can be done.
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.
