Hunters Point features small homes that run on solar power and made out of carbon fiber materials. Is this the future of housing? (Photo from Pearl Homes)   A new neighborhood in a fishing village south of Tampa, Florida called Cortez is aiming to be the most energy efficient neighborhood in the community. A new development called Hunters Point will feature small homes that will run on solar power to reach a “net zero” energy footprint with the help of Google Home to make sure ...
H2GO Power would utilize low-cost hydrogen production and storage technologies using nanomaterials that can store the gas and provide energy on-demand. (Image credit: H2GO Power)   According to a 2017 report from the EIA (Energy Information Administration), energy consumption from developing nations will increase 28% by 2040, and while renewables can be implemented very quickly, the energy infrastructure in those nations is lagging behind the rest of the world. To help meet the rising powe ...
Not long ago my son decided that he wanted an Arc Reactor for Halloween; something simple to wear and looks awesome -seems I got some homework-.     In the past I've done other versions of this project which let's say I'm not 100% proud of -design mistakes, a lot of trial and errors to fit all the parts together and the approach I took to the electronics was not up to good standards. Like some say, it is more about the journey, not the destination project , well this post is about m ...
Researchers created this tiny Lithium-ion battery using the FFF (Fused Filament Fabrication) method in a single print by exchanging the filament at specific layer heights, and then vacuum filled with an electrolyte. (Image credit: Duke/Texas State University)   Researchers from Duke and Texas State University have designed a way to 3D print Lithium-ion batteries in nearly any shape imaginable. One of the challenges manufacturers face today, is that mobile devices, electric vehicles, and we ...
Solar Chernobyl’s Solar Farm covers 1.6 hectares of land, uses 3762 solar modules, and produces 1-megawatts of power. (Image credit: Solar Chernobyl)   During the night of April 26 (1986), workers at the No. 4 light water nuclear reactor at the Chernobyl Nuclear Power Plant performed a safety test that simulated a station-wide power blackout, and safety systems were intentionally turned off to test the plant’s backup safety systems.   Unfortunately, the plant itself was ...
A rechargeable zinc battery will be a cheaper and safer alternative to the standard lithium-ion batteries. NantEnergy’s rechargeable zinc battery. (Photo from NantEnergy)   Lithium-ion batteries are important when it comes to powering electric cars and storing energy created by solar panels and wind turbines. But they still have their fair share of issues, such as their vulnerability to fires and explosions, their use of scarce minerals, and how expensive they are. Zinc batteries wou ...
As most established engineers will tell you, the best lessons learned are honestly from things we’ve screwed up in the past. One of my first mentors told me that and I’d have to agree 100%. Nothing burns itself into your mind quite as well as something that has bitten you on the other end.   With that in mind I wanted to share a recent experience I had with one of my favorite new devices in hopes of saving some of you future frustrations. The IRPS5401 is a multichannel PMIC fro ...
Scientists have studied that farming renewable energy in the Sahara Desert would improve the life of its population. They foresee that planting wind turbines and solar panel in the biggest hot desert in the world would supply electricity to the entire world. Results of the simulation: quantity of rainfall across the Sahara and around after implementation of the project.

After all this time and technological advancment, we still need to learn more about H2O (Photo via iStock)   You may think you know everything about water, thanks to middle school science classes. Scientists thought so too, but a team at New York University recently discovered new molecular properties of water that had previously gone unnoticed. Water is an efficient transporter of its own autoionization components, which are the charged particles, protons, and hydroxide ions created whe ...
Physicists from MIT create a new material that produces a record amount of energy under a strong magnetic field. MIT finds a way to significantly boost thermoelectricity’s potential. (Image via MIT)   We’re constantly looking for ways to make energy self-sufficient and more eco-friendly. One possible method is using the heat generated from certain objects to create energy. For instance, the heat generated from your car engine could help power your car. This is possible if impro ...
University of Arkansas researchers have shown that the motion of graphene could supply an unlimited amount of clean energy. (Image credit: Pixabay)   Graphene advancements are rolling out on a regular basis, with new developments in production, strength, and have even used it to create 3D printed objects. Researchers from the University of Arkansas have also utilized the material to create a source of potential unlimited clean energy, thanks to its flexibility.   Professor Paul Thibad ...
A new membrane technology uses a process to extract hydrogen from ammonia to fuel cars. The CSIRO team hard at work on the membrane technology. (Photo via CSIRO)   In the never-ending quest to create fuel-efficient and eco-friendly cars, hydrogen fuel seems like a great option. Unfortunately, it presents a whole mess of problems, like being highly flammable, figuring how to store it, and being difficult to ship due to its low density. These issues prevent hydrogen from being progressed as ...
The UK has been having really nice (hot) weather recently, although there was a brief rainstorm, and possibly lightning during periods over the last few days. We have small pear and plum trees, about 15-20 feet high perhaps. Anyway, the leaves looked really strange today : ( I'm not sure, but I'm wondering if lightning caused it. There are large trees from neighbouring properties that are much taller, and close by. There was some scattering of strange leaves in them too, and generally in the s ...
Murata's small energy devices (UMA series) can be charged very quickly because they can be charged-discharged at a high rate of 10C or more.   If using UMA series as main power supply, you can use the equipment soon by quick charge even when power runs out. In this demo video, further details are provided with comparisons to supercapacitors. UMA series - Application example: Main Power Supply     Related articles: Part 1: Murata to realize Energy Harvesting for IoT - UMA se ...
Researchers at Harvard have created a new organic molecule for flow batteries that promises to be a longer lasting and inexpensive alternative to lithium-ion batteries. This flow battery uses a new organic molecule that’s longer lasting and performs better than other flow batteries outlives and outperforms its predecessors (Photo via Harvard)   Harnessing energy from clean sources is important if we want to replace fossil fuels that are polluting the earth. The problem is we need a w ...
