Why the Public Perception of Tesla is TOTALLY wrong:
Shared by Michael Michalchik.
Almost everything commonly told about Tesla is wrong! He didn’t invent AC, he didn’t battle Edison over AC vs. DC, he didn’t even have a rivalry with Edison, he didn’t want to give everyone free electricity and he wasn’t a Physics genius! Referencing primary sources I can show you why we have such a perverted view of Tesla’s real accomplishments and life.
According the company, this innovative system enables the detection of live objects behind walls at a distance of more than 50 meters.
Camero-Tech, a member of the SK Group and an Israeli developer, producer, and marketer of pulse-based UWB micro-power radar ‘Through Wall Imaging’ systems, announced the launching of its groundbreaking XaverTM LR40 (XLR40) system, which detects live objects behind walls at distances of over 50 meters.
Italian company Energy Dome has announced the successful launch of its first CO2 Battery facility in Sardinia, Italy. The milestone marks the final de-risking of the CO2 Battery technology as Energy Dome enters the commercial scaling phase, becoming the first commercial long-duration energy storage technology on the market offering a reliable alternative to fossil fuels for dispatchable baseload power globally.
The Energy Dome CO2 battery uses carbon dioxide to store renewable energy, such as solar and wind energy, over a long period and release it quickly. Energy Dome says the technology can be quickly deployed anywhere in the world at less than half the cost of similar-sized lithium battery storage facilities.
Energy Dome began its operations in February 2020 and has progressed from a concept to full testing at a multi-megawatt scale in just over two years. This successful launch is also in part due to the unique nature of Energy Dome’s process, which integrates known components in a novel industrial process based on a thermodynamic transformation of CO2.
Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks — according to new research (Nature Materials, “Long-term solar water and CO 2 splitting with photoelectrochemical BiOI–BiVO 4 tandems”).
The findings, co-led by Dr Virgil Andrei, a Research Fellow at St John’s College, University of Cambridge, with academics at Imperial College London, could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.

Italian company Energy Dome has opened the first of its remarkable grid-level energy storage plants. These “CO2 batteries” can store renewable energy over long periods and release it quickly, at less than half the cost of big lithium batteries.
Large-scale energy storage is going to be required on an epic scale all round the world, as green energy begins to take over the world’s power supply. Renewable energy is often generated at times and places where it’s not needed, and a variety of grid-level storage technologies are jockeying for various energy market niches, each with their own strengths and weaknesses.
We took a close look at Energy Dome’s CO2 battery technology last July, but here’s the guts of it: carbon dioxide expands dramatically when it moves to a gaseous state from a liquid state, which it’ll only settle in under pressures at least five times higher than the Earth’s atmospheric pressure. How much does it expand? Well, at room temperature, 2.5675 litres of liquid CO2 kept at 56 atmospheres of pressure will expand into 1,000 litres of gaseous CO2. That’s a factor of nearly 400.
Organic farmers are returning to an unusual tool in the fight against weeds — fire. Called ‘flame weeding’ the process involves either using a small, handheld flamethrower, or installing a pretty hardcore row of flamethrowers onto the front of a tractor and slowly driving through fields of crops singeing the weeds in between the rows.
Flame Engineering, Inc. specializes in developing and selling flame weeding equipment and says the technique is rooted in science. The company’s website explains that the technique is not about blasting the weeds to kingdom come, but rather about focusing on destroying cell structure.
“Flame weeding is what we like to call a ‘slow kill.’ Essentially, you are destroying cell structure in the plant leaf. The weed will no longer put energy toward growth (photosynthesis) taking the kill through the root system. YES, flame weeding will kill the roots too! Even on big weeds (over 6″), you will see a stunning effect and even a kill within a few days, depending on how established the root system is and how long the plant was exposed to heat.”
One day soon, buildings could become more energy-efficient—and environmentally sustainable—with insulating material developed from wood by researchers in Sweden. The newly-developed material offers as good or even better thermal performance than ordinary plastic-based insulation materials, according to researchers reporting recently in ACS Applied Materials & Interfaces.
Yuanyuan Li, an assistant professor at Wallenberg Wood Science Center, KTH Royal Institute of Technology in Stockholm, says that the new insulating material is an aerogel integrated wood which is made without adding additional substances.
Wood cellulose aerogels themselves are nothing new—researchers have been developing advanced types of aerogels and other composites for the last several years in the Wallenberg Wood Science Center at KTH—but Li says the new method represents a breakthrough in controlled creation of insulating nanostructures in the pores of wood.
In 2008, when gasoline was even more expensive than it is today, the world dreamed of cars that could run on nothing but air.

Unlike other plasma jet engines, this new Chinese one can actually work in the atmosphere. This could prove revolutionary for the aerospace industry.
