Elon Musk has already shaped our world in several different ways, and the debate of whether they’re all beneficial to humanity is ongoing. But apart from putting electric vehicles on top of the automotive world’s agenda and making us dream about outer space travel, there is one somewhat unintentiona…
Nowadays, the development of renewable energy sources, such as wind, solar, and nuclear energy sources, has become imperative, due to the limited resource constraints of the traditional fossil fuels [1 ]. However, these renewable sources could not deliver a regular power supply as the sources are variable in time and diffuse in space. Thus, the focus has been shifted to the electrical energy storage to smooth the intermittency of the energy sources. Rechargeable battery has the ability to store chemical energy and convert it into electrical energy with high efficiency [ 2]. Lithium-ion battery (LIB), as one typical rechargeable electrochemical battery, has dominated the markets of portable electronic devices, electric vehicles, and hybrid electric vehicles in the past decades, due to its high output voltages, high energy densities, and long cycle life; even though the high cost and the shortage of lithium resources are inhibiting the application of LIB in large-scale energy storage [[3], [4], [5], [6], [7], [8], [9]].
Sodium-ion battery (SIB) is one promising alternative to LIB, with comparable performance to that of LIB, abundant sodium resources and low price of starting materials [[10], [11], [12], [13]]. As Na atom is heavier and larger than those of Li atom, the gravimetric and volumetric energy density of Na-ion battery are expected to not exceed those of the Li analogues [14]. However, energy density would not be considered as the critical issue in the field of large-scale grid support, for which the operating cost and the battery durability are the most important aspects [15,16].
A new disposable battery is made of paper and other sustainable materials and is activated with a few drops of water.
Sandy and Cory discuss the evolution of Model 3 and Model Y bodies in white over the last five years. Sandy points out the massive advancements that have been made and encourages other OEMs to pursue similar efficiency and lean design.

We all know that Elon Musk is a genius when it comes to technology. He’s the mastermind behind Tesla, SpaceX, and now he’s working on developing futuristic smart cities.
A new solar panel design can efficiently convert light into electricity, while still allowing almost 80% of incoming light to pass through.
Presently available in France, the “Electric As You Go” program is for private customers who wish to change their old vehicle to an affordable, sustainable one. Trying to break through ‘” the cost is too much to invest in an EV” scenario (which becomes more disputable each hour of each day), Stellantis introduced “Electric As You Go” and is promoting a more affordable long-term rental program dedicated to battery electric vehicles (BEVs).
The program claims it is efficiently designed to offer breakthrough competitive prices to Stellantis customers. The offer is starting in France and looks hopeful.
There is the customary but “limited” initial down payment and a monthly fee that starts from €110 per month plus a cost of 7 cents per kilometer with a 500 km minimum per month. This new offer frames itself as a breakthrough project. “The main goal of the program is to offer the opportunity to better adapt the total cost of the vehicle to its real use.”
National Hurricane Center data for Miami, Washington, D.C., and New York City show development happening in at-risk areas, even as climate change brings more frequent and intense storms.
Perovskites, mineral materials composed of calcium titanate, have been found to be valuable for the fabrication of high-performance solar cells. While teams of scientists and engineers worldwide have been developing and testing perovskite solar cells in laboratory settings, large-scale outdoor evaluations of these cells are still lacking.
Researchers at University of Rome Tor Vergata, the Hellenic Mediterranean University in Crete, BeDimensional S.p. A., Great Cell, the Italian Institute of Technology (IIT) and University of Siena have recently manufactured large-area perovskite solar panels engineered using two-dimensional (2D) materials. They then successfully integrated 9 of these solar panels into a stand-alone solar farm, located on the Greek island of Crete. This team’s findings, presented in a paper published in Nature Energy, could facilitate and inform the future large-scale implementation of perovskite solar cells.
“Our recent paper highlights our joint research efforts for the last 5 years in the upscaling of perovskite PVs, starting from lab cells to modules, panels and finally to a solar farm infrastructure,” Francesco Bonaccorso, one of the researchers who carried out the study, told to Tech Xplore. “This project was specifically developed in the context of the European Graphene Flagship initiative, which established a close collaboration between University Tor Vergata, BeDimensional S.p. A., GreatCell and Hellenic Mediterranean University, having both complementary and widely different skillsets.”
“This is a significant milestone in renewable technology production. From touch screen displays, biosensors, radio frequency identification tags, electric vehicle batteries, and more, the technology’s applications are vast,” said Stuart Jara, HydroGraph chief executive officer.
With growing possibilities for printed electronics every day, the need for conductive inks like graphene ink is on the rise. HydroGraph’s highly competitive cost and mass production method for high quality graphene opens up a wealth of opportunity for the practical applications of conductive ink patterns.
“Once the ink is made, it can then be deployed in regular inkjet printers to make small-scale, flexible electronics. This puts manufacturing capabilities into the reach of many, making it far more accessible,” said Dr. Chris Sorensen, HydroGraph vice president R&D.
