Tesla’s Graffiti Revolution | From Concrete To Art: Giga Berlin’s Unique Makeover
#GigaBerlinArt #TechPainters #RoboticMuralist.
At Tesla’s Gigafactory Berlin-Brandenburg, creativity meets technology in a remarkable initiative to transform concrete surfaces into stunning artworks. Inspired by Elon Musk’s vision to turn the factory into a canvas, the project began with local graffiti crews. However, the sheer scale of the endeavor required innovative solutions, leading to the collaboration with a robotic muralist startup. This groundbreaking graffiti printer combines cutting-edge technology with artistry, using a triangulation method to maneuver its print head along factory walls. With 12 paint cans onboard, the robot sprays precise dots of color—10 million per wall and 300 million for the west side alone—creating intricate designs composed of five distinct colors. The curated artworks draw inspiration from Berlin’s vibrant culture, Tesla’s groundbreaking products, and the factory itself—described as “the machine that builds the machine.” A blend of global and in-house artistic talent has contributed to the ongoing project, making Giga Berlin not just a hub for innovation but also a celebration of art and ingenuity.

Transparent device harvests radio frequency and solar power to improve power outputs
Wireless communications technology has transformed the world, but the devices, which are quickly growing in number, require a consistent and ample source of power. Dong et al. developed a transparent device that harvests energy from two sources — radio waves and the sun — to power a wide range of wireless devices.
The breakthrough represents a significant step forward in optimizing energy conversion, since previous systems typically focused on harvesting either radio frequency or solar power, but not both. For example, coupling the energy harvester device with a solar cell increases the solar cell’s maximum power output by 13.11%. Furthermore, the device demonstrates an optical transparency of over 80 percent, allowing it to be invisibly integrated into many next-generation wireless technologies as both an energy harvester and a light transmitter.
Device may make smart windows and the Internet of Things more energetically sustainable.
Hydrogen in Minutes: The Microwave Innovation Changing Clean Energy
Scientists have unlocked a groundbreaking way to produce clean hydrogen using microwaves, drastically reducing the extreme heat required for conventional methods.
By harnessing microwave energy, the team lowered the reaction temperature by over 60%, making hydrogen production far more efficient and sustainable. A key breakthrough was the rapid creation of oxygen vacancies, essential for splitting water into hydrogen, in just minutes rather than hours.

Google’s X spins out Heritable Agriculture, a startup using AI to improve crop yield
Google’s X “moonshot factory” this week announced its latest graduate. Heritable Agriculture is a data-and machine learning-driven startup aiming to improve how crops are grown.
As the firm noted in an announcement post published Tuesday, plants are incredibly efficient and impressive systems. “Plants are solar powered, carbon negative, self-assembling machines that feed on sunlight and water,” Heritable wrote.
Yet agriculture puts a massive strain on the planet and its resources, accounting for around 25% of anthropogenic greenhouse emissions. It’s the planet’s largest consumer of groundwater and can lead to soil erosion and water pollution via pesticides, fertilizers, and other chemicals.
960-hour Stability Marks Milestone in Lithium-Air Battery Technology
Researchers develop a catalyst boosting lithium-air batteries with 0.52V, 960-hour stability, and 95.8% efficiency, advancing energy storage.
Aerial robot can navigate unknown environments safely at high speeds
A team of engineers and roboticists at the University of Hong Kong have designed, built and tested an aerial robot capable of navigating unknown environments safely at high speeds while avoiding obstacles. In their paper published in the journal Science Robotics, the group describes how they overcame problems encountered by others attempting to build similar robots and how well their quadcopter robot, called SUPER, performed during testing.
Roboticists have been trying for several years to build a flying robot that could perform like birds—moving safely at high speeds while adjusting to unknown conditions as they arise, such as encountering gusts of wind, power lines, tree limbs or other objects appearing suddenly in their path.
Most such flying robots have relied on various types of sensors and cameras that had to process massive amounts of video data, slowing the speeds at which they could operate. In this new effort, the researchers in Hong Kong say they have finally overcome these challenges.
Report reveals how the state of our oceans is intrinsically linked to human health
A study published in the journal One Earth explores how marine biodiversity conservation, human health and well-being are connected. The results suggest that marine protected areas can be good for both planet and people.
These areas of the ocean are legally recognized by governments as being important for marine conservation. They are protected by putting limits on human activity within and around them.
Once a government declares a marine protected area, you usually can’t live in it, fish, build a beach resort, start a fish farm or drill for oil in it. The rules vary from place to place, but the idea is to allow nature to flourish by limiting human activity as much as possible.
This Groundbreaking Hydrogel Generates Hydrogen and Oxygen via Artificial Photosynthesis (Using Water and Light)
In a major leap toward sustainable energy, a team of Japanese researchers has developed an artificial photosynthesis system that could help generate hydrogen and oxygen from just water and light. The breakthrough is thanks to a new type of hydrogel, which mimics the natural process of photosynthesis and performs these reactions without requiring external energy. This innovation opens up exciting possibilities for clean energy production, potentially transforming the way we think about renewable resources.
Artificial photosynthesis has long been a goal for scientists looking to replicate the natural process plants use to convert light into energy. The concept is simple in theory: use light to drive chemical reactions that produce useful energy, such as hydrogen. However, previous attempts to harness this process have been hampered by the need for external energy to trigger the reactions, making the systems inefficient and difficult to scale.
Enter hydrogels —a promising new solution. These polymer-based materials are capable of responding to external stimuli like temperature, light, and pH. The challenge, however, has been that these materials often suffer from self-aggregation, where the molecules clump together and hinder the energy conversion process. The Japanese researchers, however, have overcome this obstacle by designing a hydrogel that maintains the precise arrangement of its molecules, enabling a more effective energy transfer.
