Swiss pilot Bertrand Piccard completed the world's first intercontinental flight in a giant solar powered plane.

After the19-hour voyage from Madrid on his experimental carbon-fiber aircraft, Piccard landed in the Moroccan capital Rabat Tuesday night. Thirteen years prior, Piccard set another record on the world's first non-stop around-the-world balloon flight.

The Solar Impulse, an aircraft as big as an Airbus A340 but as light as an average car, had 12,000 solar cells on the wings turning its four electrical motors. Each of the motors charges 880-pound lithium polymer batteries during the day, enabling the aircraft to carry on flying at night.

"Solar Impulse has demonstrated that a solar-powered airplane can fly day and night using no fuel. The next challenge is to fly around the world," the organizers said on their website solarimpulse.com.

For the next five days, the Solar Impulse will stay in Rabat before taking off to Ouarzazate in the south of Morocco for the launch by King Mohammed VI of the construction of the largest-ever solar thermal plant.

"The question is not to use solar power for normal airplanes," Piccard told AFP in Madrid. "The question is more to demonstrate that we can achieve incredible goals, almost impossible goals, with new technologies, without fuel, just with solar energy, and raise awareness that if we can do it in the air, of course everybody can do it on the ground.”

In 2010, the aircraft made history as the first manned plane to fly 24/7 on just the power of the sun. It also holds a record for staying aloft for over 26 hours, setting yet another record for altitude by flying at 30,298 feet.

The Solar Impulse's 1,500 mile trip is just a rehearsal for the aircraft's planned trip around the world in 2014.

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
