Dubbed GEH2, the hydrogen system has a size of 1,150×2,200x3350mm and weighs in at 3.5 tons. It features IP43 ingress protection and is able to operate at temperatures between-5 and 45 degrees Celsius. Its output voltage is between 230 and 400 V.

The generator has a power of 110 kVA and its lifetime is guaranteed for two years or 15,000 hours. Its autonomy at 50% of prime running power is around eight hours. It can be started instantaneously and also features a double adduction system that allows continuous operation.

The contract is aimed at design demonstration, says the awardee.

The U.S. Army has moved a step closer to a future where it uses directed energy weapons to counter its adversaries. The Rapid Capabilities and Critical Technologies Office (RCCTO) of the U.S. Army has awarded a contract to General Atomics Electromagnetic Systems (GA-EMS) and Boeing to develop a prototype of a 300kW-class laser weapon system, a press release said.

In its efforts to strengthen its Short-Range Air Defense (SHORAD), the U.S. military is using multiple approaches. Earlier this week, we reported that General Dynamics was teaming up with Epirus Inc., to deliver a directed energy weapon using high-power microwave technology. The weapon developed through this collaboration will find its way on the Stryker combat vehicles that General Dynamics makes for the U.S. Army.

In groundbreaking new research, scientists have made a structural battery 10 times better than in any previous experiment.

What’s a structural battery, and why is it such a big deal? The term refers to an energy storage device that can also bear weight as part of a structure—like if the studs in your home were all batteries, or if an electric fence also held up a wall.

Trees make everything better. Even EV batteries.

Trees provide the air we breathe, and now, in an interesting turn of events, they might also help to power our electronics. A team of researchers from Brown University and the University of Maryland developed a new material that can be used in solid-state batteries to improve the safety and power of traditional batteries by replacing the liquids typically used in lithium-ion cells, a press statement reveals.

The material in question is a kind of cellulose nanofibril, which takes the form of polymer nanotubes derived from wood. The researchers found that it could be combined with copper to produce a paper-thin material that has an ion conductivity between 10 and 100 times better than other polymer ion conductors.

While renewable energy sources like solar and wind have now become cheaper than fossil fuels, developing long-term energy storage is key to overcome their intermittency. Lithium-ion batteries are the state-of-the-art battery technology but they can only cost-effectively provide energy for about 6 hours. So, what if we could extend the battery duration to 100 hours… out of thin air … and rust? Literally!

Good day to you all, Hertz have certainly smelt the coffee… will the rest of the world catch up? It is a fact. Clean energy already beats dirty energy and the gaps will only increase with time. It is also a fact that we will produce more than we need, and it will be much cheaper than it is today. Just imagine what global problems could be solved with cheap, clean, abundant energy! If you want more detail then in this video I look at where we are, how mis-pricing of legacy generation is making them appear less expensive than they really are, and how incorrect projections for solar, wind and batteries are giving decision makers flawed future projections, and how clean, renewable energy could help solve some of the greatest problems we face…quickly. Have an amazing day.

Clean energy future — cheap abundant energy will solve so many problems.

It is a fact. Clean energy already beats dirty energy and the gaps will only increase with time.

Scientists are coming up with practical and cheaper desalination processes for water. It has been going on since half a century ago in Spain. Currently, Ikaria, a Greek island, got access to clean water by virtue of desalination.

The common method used in the process is called reverse osmosis (RO) but it has to be connected to the electricity grid. This is expensive and inaccessible for areas far from the grid. So, researchers have come up with sustainable off-grid desalination systems that run on renewable energy.

Now, microbial desalination cells (MDCs) are being suggested to use. This is developed by MIDES. It produces drinkable water from the sea. It means electro-active bacteria desalinate and sterilize water making it suitable and safe. “This technology offers new options to provide clean water and wastewater treatment to small, isolated locations without electricity,” said Frank Rogalla, director of innovation and technology at Aqualia and a member of the project team.

The volcano bitcoin mining is also super eco-friendly: 3.

El Salvador has officially begun to mine Bitcoin using the power harnessed from an honest-to-god volcano — and the so-called “volcanode” has already made 0.00599179 bitcoin, or about $269, according to a tweet by president Nayib Bukele.

“We’re still testing and installing, but this is officially the first Bitcoin mining from the volcanode,” Bukele wrote.

Relying on green geothermal energy to mine Bitcoin makes a lot of sense given that the process is extremely power intensive.

I woke up this morning, saw the COP26 headlines and was so irate I had to share my thoughts.

Please excuse this unplanned video.
I woke to headlines this morning that made me so mad I just had to set up my camera to give my thoughts.
My next videos will be on power, precision fermentation and biochar so keep your eyes open.
And remember the future is NOT someone else’s problem.
