We all know glass comes from sand but we don’t always get to see this process in action. In this video, we bring you footage of a solar-powered 3D printer that makes glass sculptures out of sand. Impressed? Just wait till you see the clips.

The 3D printer is called Solar Sinter and it was built by Markus Kayser. It works in the following way: after computer-drawn models are loaded into the machine, a large Fresnel lens beams sunlight onto a sandbox which leads to high temperatures of 2,552–2,912 F (1,400–1,600 C).

2021 is only halfway complete, and we cannot yet be said to have defeated the pandemic, but yet at the same time, the travel and tourism industry is said to be poised for a pretty rapid boom. In many ways and places, the recovery has already begun.

A live Globaldata poll showed that people are desperate to enjoy travels and trips again with a majority of them opting for longer trips than before. 26% of their respondents showed a desire to enjoy trips that spanned a minimum of 10 nights. As lockdowns and travel restrictions continue to be eased and countries continue to open up, we will likely see a surge in new tourists and travelers.

Jason Fong, a veteran of the industry, is the brain behind the Boss of Bali brand, a brand that has garnered over 2 million followers on Instagram. Fong shared his knowledge of all things tourism and how he has used his platform to promote the evolution of travel and tourism more sustainably.

By using a compound derived from a Himalayan fungus and used for centuries in Chinese medicine as a jumping off point, scientists have developed a new chemotherapy drug with powerful anti-cancer effects. Doing so involved chemically altering the compound to better infiltrate cancerous cells, which proved to boost its potency by up to 40 times.

A simple cooling system driven by the capture of passive solar energy could provide low-cost food refrigeration and living space cooling for impoverished communities with no access to the electricity grid. The system, which has no electrical components, exploits the powerful cooling effect that occurs when certain salts are dissolved in water. After each cooling cycle, the system uses solar energy to evaporate the water and regenerate the salt, ready for reuse.

“Hot regions have high levels of solar energy, so it would be very attractive to use that solar energy for cooling,” says Wenbin Wang, a postdoc in Peng Wang’s lab. In many parts of the world, there is a greater need for cooling because of climate change, but not every community can access electricity for air conditioning and refrigeration. “We conceptualized an off-grid solar-energy conversion and storage design for green and inexpensive cooling,” Professor Wang says.

While most automakers are laser-focused on improving their batteries, the CEO of EV startup Lucid Motors says the battery pack is “totally overrated.”

Tesla has unveiled its latest structural battery pack with 4,680 cells during a Gigafactory Berlin tour ahead of Model Y production at the new factory.

The start of production at Gigafactory Berlin is not just significant for Tesla’s growth in Europe, but it will also mark the launch of an important new version of the Model Y. Tesla plans to build the new Model Y at Gigafactory Berlin on a whole new platform with its structural battery pack.

Earlier this year, Electrek obtained the first image of a Tesla structural battery pack prototype.

Forget science fiction — Silicon Valley start-up Light Field Lab has created a hologram so real that I could put my hand right through it.

The historic mission is still going strong.

A Chinese lander and rover are still up and running more than 1,000 Earth days after they made a historic first-ever landing on the far side of the moon.

The Chang’e 4 lander carrying the Yutu 2 rover touched down in Von Kármán Crater on Jan. 2 2019, and the robotic mission has been exploring the unique area of our celestial neighbor ever since.
