Contemporary Amperex Technology Ltd created a new battery for electric vehicles that will take the electric cars sector to new heights. Sign of CATL in front of company building. (Image credit: CATL)   The most important part, and the source of anxiety in buyers, of electric vehicles is the battery. Many companies have been competing to put on the market an electric vehicle with the longest-lasting battery. The issue is that the battery of an electric vehicle (EV) is expensive to produce a ...
GE joins the race to sustainable energy for all with its new wind turbine project. The company wants to build the tallest wind turbine in the US by 3-D Printing the base. Prototype of a 10 meter base for the wind turbine. (Image credit: GE)   GE announced that it is planning to build a wind turbine taller than some of the landmarks in the area, like the Seattle needle! Such a big endeavor called for international cooperation: GE, COBOD – a reputable European 3-D printing company, and ...
Charging stations around the world have significantly increased (Image Credit: Tesla)   Electric car charging points are on the rise around the world, and a new report details just how rapidly they’re growing. The International Energy Agency’s (IEA) recently published the 2020 EV Outlook report analyzes a number of crucial data points related to electric vehicle adoption, such as charging infrastructure.   Usually, charging infrastructures have been described as the R ...
Stanford University consistently brings us innovation. It’s astounding. An example of that is the team of engineers who created a clever way to transmit electricity wirelessly. The technology could send electricity to moving electric cars, drones and robots, and could be applied to electric cars driving on the highway or drones flying in the sky after it is scaled up.   Although a revolutionary idea, wireless electricity is a project, the team had been working on for a while now. Sh ...
The industry of coal is facing obstacles that suggest the industry might disappear completely in a near future. Progression of the Consumption of coal since 1950. (Image credit: EIA.GOV)   There was as time when light revolved around renewable sources of energy, in an indirect way. Water or wind power for mills, for example. Nowadays, electricity is generated through exploiting non-renewable sources − natural gas, coal and nuclear energy. In fact, in the US coal is the primary fuel u ...
Some researchers at the National University of Singapore developed an energy generator that utilizes a combination of light and shadow to produce electricity.

Nature based energy scavenging being pushed at every front, water, air, and the sun. However, nobody ...
  Xinc8 has developed a new type of battery that will outperform lithium-ion batteries one day. (Image Credit: Zinc8)     A new type of battery that won’t degrade, can’t explode, and is up to five times cheaper than lithium-ion batteries will be available on the market. Zinc8, a Canadian-based company, has developed the new zinc-air hybrid flow battery, which has adaptable storage capacity and has the potential to outperform lithium-ion batteries. This device could r ...
A very popular HIOKI instrument is the BT3554 battery tester. It's a portable instrument designed primarily for maintenance purposes with voltage ranges up to 60V. Of course the BT3554 won't blow up when you accidentially apply 61V to it instead of the maximum 60V. In fact there are not many service cases for the BT3554 at all. However, about 9 out of 10 BT3554 that arrive in HIOKI's service department in Frankfurt, Germany are identified to have suffered some sort of over-voltage. The majori ...
Artist’s impression of electron spins “frustrated” as the magnetic sample is forced into a spin liquid state. (Image Credit: Daniel Haskel)   Researchers at the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Argonne National Laboratory, inserted a magnetic crystal between two small flat-head diamonds and slowly squeezed them together to create a magnetic liquid. This study, published in Physics Review Letters ...
Renewable energy has surpassed coal in April 2020 for 40 straight days. (Image Credit: Myriam Zilles from Pixabay) To date, the coronavirus pandemic has brought some positive changes on the planet, including decreased air pollution, wildlife roaming around freely, and more recently, the United States has seen an uptick in clean energy. During the economic decline as a result of mandatory stay-at-home rulings, renewable energies have started to gain momentum. Figures from the U.S. Energy Informat ...
I feel very fortunate to have gotten to jump right into board design right out of school, which I can't believe was so long ago. The first 6 years of my career was a trial by fire that taught me a lot of great lessons on design practice. To this day I still make recommendations on designs based on what I learned about designing in plenty of operational margin and saving cost wherever you can. Yes those things don't really go together, but the point is I never take for granted the value inherent ...
Inspired by Using a DC-DC Isolator to allow single power input to case? (and to stop hijacking that post) I'm checking the output noise of a Traco Power DC-DC converter. The  device I have is the TEN 6-4822WIN. It translates 48 V into +- 12 V. In this post, I'm using its +12 V to power my dc load in two situations: with and without fan.       I'm using a very naive approach, directly using the switcher output to power an analog circuit and the fan. And virtually no outpu ...
Governments around the world are more and more open to electric cars as a viable way to reduce their countries’ CO2 production; but the benefits are still controversial. (Image credit: from vectorstock.com)   Nobody knows the exact time humanity started to worry about the environment. Some people even don’t think there is much to worry about. However, we can all see that technology has embraced the challenge of finding or creating “cleaner” sources of energy. While ...
The device could capture terahertz waves and convert it to DC current, which could power-up electronic devices. (Image Credit: José-Luis Olivares, MIT)   Physicists at MIT have achieved a new scientific breakthrough that could one day allow household devices to be powered-up by direct current produced from terahertz waves. A terahertz wave, which is emitted by any device that sends out Wi-Fi signals, is an electromagnetic wave with a frequency between microwaves and infrared light. ...
BlueWave Solar is currently working on installing solar panels that won’t take over cropland on farms. Solar energy could help improve farming, but there are some challenges to overcome first. (Image credit: Dennis Schroeder, NREL)   As the demand for renewable energy increases, farmers are looking for new ways to make their own farms greener. Solar panels are a popular option, and while it’s not uncommon, they come with their own set of challenges. You don’t want the pan ...
