As companies race for the latest and greatest alternative fuel to compete with oil, a number of options have arisen. Ethanol, biodiesel, even the lesser known isobutanol all hold promise, but one major problem is in the engines these fuels are supposed to run. Costly modifications are needed in many cases to operate on alternative fuels, and even then you are limited to one fuel or another. Why not just create an engine that can run on virtually any kind of fuel? That’s the approach being taken by Raytheon Integrated Defense Systems in a deal signed with Cyclone Power Technologies.

The all-fuel Mark V “clean-tech” engine, a Rankine Cycle heat-regenerative external combustion engine, can run on virtually any fuel. Ranging from biodiesel to waste oil, whichever fuel is used, the engine even emits fewer emissions than modern gasoline engines.

The Mark V engine works by heating and cooling water in a closed-loop piston-based system.

Cyclone Power Technologies’ founder, Harry Schoell, was named Popular Science’s “Inventor of the Year” in 2008 for the invention of the company’s “Cyclone Engine,” the predecessor to the Mark V.

"After months of rigorous engine testing, we're pleased to say that Cyclone and Raytheon are now entering the next phase of our working relationship. We are designing and building engines such as the MantaRay (a modified version of the Mark V) for Raytheon and their customers, and starting to generate revenue from these operations. We're very pleased to be working alongside such a well established and respected company and look forward to building our relations going forward," says Schoell.

Considering that national development efforts in various countries are moving toward multi-fuel infrastructure, this engine—if applied to personal transportation—may offer a unique option to consumers. Can’t find a gas station? No problem, just fill up with used cooking oil. Want to support locally produced ethanol? That works too! As fuel options become more and more prevalent, those with multi-fuel engines running their vehicle will have the benefit of choosing from the most economical option, or even the most convenient depending on location. However, let’s not be too hasty in our excitement. After all, it is Raytheon’s Integrated Defense Systems division that is funding the project, so likely the technology will become a cog in the war machine before it’s put to any kind of practical day-to-day use.

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.
