Discover Clean Military
The ongoing issue of providing power to personnel and facilities in a mission environment is always met with the interruption of power generation due to fuel availability and/or breakdown of infrastructure delivery sometimes caused by combat situations.
Existing technology is based on standby power generation units typically powered by diesel or jet turbine engines. The amount of fuel required to generate power from these units is very expensive and rely on the supply of fuel trucks to maintain operation which sometimes is interrupted with combat situations as mentioned earlier. With the cost of the fuel, coupled to the cost of getting the fuel to the site, it becomes very expensive and fuel economy and efficiency should be of upmost importance.
Engines used in today’s power generation units are far from efficient and have had slight improvements in the 60 plus years they have been around. It is now time to consider something outside of the box versus trying to enhance existing technology.
The military has studied other alternatives such as solar power but in reality, the use is not conducive to today’s military arena. If you consider the fact that it would take approximately 166 acres of solar panels to produce 40 megawatts of power, it would be obvious that delivery, maintenance and protection of those panels make existing technology look very good. This manner of power generation would boil down to about $7.00/watt of power which is very expensive and not feasible.
Engine Technology Outline
As the initial step, we would propose that existing diesel engines be outfitted with our retro-fit technology in order for them to obtain an efficiency gain of 15 -24 % while extending life cycle times by a factor of two due to reduced thermal load and optimized burn. Our standalone engine control unit (ECU) has the ability to also adjust and optimize burn characteristics to accommodate mixed diesel fuels whether there is introduction of propane, methanol, synthetic fuels, alcohols and biofuels whereby offering true multi-fuel capability.
Beyond the retro-fit technology and while further developing our process based on specific platforms, RTU can offer our new short stroke diesels, which are much smaller in physical size to existing diesel engines. They are 60 % more efficient to conventional diesel platforms and deliver better horsepower and torque figures while extending life cycles even further with the extensive use of our proprietary ceramic components. Being modular in design, these engines can be configured from small displacement to high capacity, high power applications based on the work to be performed.
Power Generation and Power Storage Unit
Coupling our engine to our generator technology, referred to as Axial Flux Radial design, the efficiency level of the generator is about 97%. The illustration below is an example of a 50 kw unit which requires low rpm for operation.
As can be seen from the graph, the power curve and low rpm requirements for a unit this size is quite substantial. The generators can be configured in a variety of power output sizes ranging from 5 kw to 400 kw and are scalable to 1 MW if required. If a power storage device (PSU) is required, RTU can also offer a proprietary unit that uses the unique performance

characteristics of ultra-capacitors to take a power charge almost instantaneously and disburse it in a regulated format. The versatile design allows us to identify the customer’s power consumption requirements and then back into a design that fits that need.
The RTU patented unique combustion technology can be retrofitted to existing engines and rendering efficiencies of 15-24% depending on engine design. Incorporating 100% of the technology in an RTU engine will offer full power and efficiencies of up to 70%. Interesting usage was considered in military vehicles, such as Hummers, LAVs, Bradleys etc as well as according to the RTU special super low friction materials and dramatic weight losses, serious enforcement is expected in air force program such as Apache turbine helicopters and other piston or turbine applications.
In summary, the various options outlined above will offer our customers power generation possibilities that are out of the box, new technology units that can bring production of mobile power production down to a reasonable cost. Solar power generation at $7.00/watt or RTU power at $2.50/watt or lower, the choice is obvious.
