Robert S. Stewart

Working with Lockheed Martin Corporation, Skunk Works, in Palmdale California USA, Stewart is helping to develop markets for their hybrid cargo airship.  Remote mining, petroleum, infrastructure (roads, railways, ports, airports, power stations and distribution lines  are often needed in the far North, across deserts, mountainous regions or in remote areas of distant foreign countries. Stewart has completed many projects worldwide building installations like this.

He believes that the new hybrid cargo commercial airship will save billions of dollars in construction costs, save years in construction time, preserve the environment, produce highly sustainable and profitable operations. He has tackled his fair share of geographic and geological challenges around the world. This technology provides a lasting and beneficial solution to feed the world with raw materials for centuries to come.

New Hybrid Aircraft Technology is now capable of dramatically lowering the costs of building these operations as they no longer depend on roads, railways, ports, ships, even airports, to move 20-500 tons of cargo into building and operating these remote mining/petroleum/infrastructure operations worldwide.

Working with several mining companies engaged in developing new mines in Africa, several of these projects that could benefit include the iron ore range in Guinea known as "Simandou Mountains, Blocks I, II, III and IV", and the Nimba Mountains.

These are being targeted along with projects in Arctic Canada, Alaska, the Andes Mountains of Columbia, Peru, Chile and Argentina, Central Asia (Mongolia, China), Western Australia, and the Middle East as examples of remote extraction projects for proving the enormous benefits of the Hybrid Cargo Commercial Airship.

See the Concepts section of this web site for further information.

Starting out in Gstaad, Saanenland Switzerland over 40 years ago, Stewart returned to Saanen in 2012 with a Master Plan to develop the region's long term Infrastructure needs over the next 35 years, in its traditional resort/farming community with major new projects.

These projects include a new, permanent Concert Hall/Conference Centre, small international/regional commuter airport with radar and runway lights, a regional hospital, an upgraded market center for local producers at new railway stations, and dozens of international conferences to attract year-round visitors.

Internationally, Stewart continues with its projects in the developing world. A new "Interop-erable", international mobile payment system is being perfected for cash transfers over mobile phones. See the final "Concepts" page of this web site for more details on the Saanenland Master Plan 2014-2050.

The Denaro Mobile Payment System will serve over one billion people in the world of cash payments with or without credit cards or bank accounts. This will change the face of global banking and international cash transfer.

It will mainly empower retail customers in the industrialized world who use outdated credit cards or cash, Third World women and entrepreneurs who will enter the global marketplace. 

The system will reduce fraud, theft and illegal money laundering while lowering costs, increasing speed and efficiency to transfer cash around the world.


The project has mass appeal for retailers in the North American, European and Asian markets wishing to offer consumers a faster, more convenient and less expensive way of making payments over mobile phones.

It is a secure and safe improvement over card payment systems incorporating embedded chips, a far cry over fraudulently-abused swipe cards. This is the lowest cost and most secure method of cash transfer over all existing systems.

The application was recently demonstrated in Nairobi. You can watch the launch on YouTube at:  .

The system being offered by the founders of this new initiative (Ian Grigg, Ken Griffiths, Robert Stewart and others) combines a standard global format that works on every manufactured cell phone and telecom system worldwide, including multiple currencies, between different countries and payment platforms. 

This is known as a "quantum game changer" in the industry, similar to the introduction of VoIP onto the long distance telephony markets in 2000. That set historic precedents for empowering over a billion people with low cost communications and entry into the formal global economy.

Another dozen projects consist of new mining, petroleum and infrastructure projects in Northern Canada, the US, Africa and Asia.

Stewart also specializes in the field of "due diligence" to help corporations and individuals to assess investment opportunities, purchases or sales of commodities and services. Fraud, misrepresentation, theft and other criminal actions are taking place with increased dominance in global markets. 

He will conduct tireless research to vet either side of a trade or investment to determine the true buyers and sellers, the commodity, its position and price, and to verify all the bone fide documentation needed for cross border investments or trading.

Stewart started his company Interop A.G. as an investment holding company in Vaduz, Liechtenstein and Zurich, Switzerland from which a number of companies operate worldwide.

The principal focus of these highly diversified operations and investments are in construction, finance, petroleum, infrastructure, mining and metallurgy with a primary focus in the Emerging Markets of Africa, Asia, the Middle East  as well as Canada and Latin America. 

Stewart is a global consultant who acts often as the Chairman/CEO of several other companies located around the world, including the USA, Canada, Switzerland and Africa.

Started in Toronto, the headquarters of the Toronto Stock Exchange and the main mining city worldwide, as well as Zurich, Switzerland, a global engineering and financial powerhouse, the company has grown since 1976 from a single client to serving over 30 world class companies, several as leaders in their respective fields.

These include project conception, initiation, planning, feasibility studies, senior management, finance, construction, implementation, commissioning, engineering and operations in the fields of mineral exploration, mining, metallurgy, exploration and production of onshore and offshore petroleum and natural gas.

To back these projects up requires additional studies and expertise developed in hydro, natural gas, solar and wind electrical power generation, biotechnology, telecommunications, aviation, railways, roads, unions, collective bargaining, community relations and all levels of government relations (municipal, provincial, federal and international.  Mining and Petroleum are complex businesses. 

This is a unique global investment house and consultancy. We offer discrete, direct assistance to Chairmen/CEO's of Multinational Corporations who are developing mining projects, minerals markets, investment proposals, and/or trade in difficult, often isolated and undeveloped regions and markets. 

Experience covers dozens of industries that go beyond mining, petroleum, infrastructure in dozens of countries over 40 years. These industries range from precious, base, industrial and strategic mineral mining and metallurgical projects, oil and natural gas exploration, production and distribution (both upstream and downstream), pipelines, power generation and distribution.As Remote mining operations often take place in the far North, deserts, mountainous regions or in foreign countries, Stewart has tackled more than the geographic and geological challenges. New Hybrid Aircraft Technology is now capable of dramatically lowering the costs of building these operations as they no longer depend on roads, railways, ports, ships, even airports, to move 20-500 tons of cargo into building and operating these remote mining/petroleum/infrastructure operations worldwide. 

Diseases like Ebola and HIV/AIDS have affected millions of workers. Interop led important discoveries in diseases and help to find many life-saving products to fight them. The airships can land in any remote location worldwide to stop epidemics like this.

Other engineering projects include airport development, researching alternative fuels, aircraft sales, construction, engineering, highways, hotels and hospitality, hydro-electric dams and power distribution, infrastructure, natural gas, nuclear power, alternative and conventional medical healthcare clinics and systems, new medical products, telecommunications, and waste recycling.

Stewart's principal interests are in the global fields of mineral development, mining, and metallurgical processing; upstream E&P petroleum discovery and development; hotel and hospitality design and development, ownership, and construction; telecoms (VoIP patents), and biotechnology used in the fields of combating HIV/AIDS and atheroschlerosis.

HIV/AIDS Research Tests, Vaccines, Cures and Prevention During the late 1970's and early 1980's, Stewart assisted medical researchers in Uganda at Mulago Hospital in the discovery of HIV/AIDS. 

Drs. Wilson Carswell and David Serwadda led research projects in Uganda in Rakai District that led to the most important discoveries of HTLVIII, later HIV. Stewart carried thousands of samples of the blood of infected victims back to Europe and America where disease research medical labs (at CDC/Atlanta, Institute of Tropical Medicine/London and Institute Pasteur/Paris) verified their findings. 

These discoveries were recognized as some of the most important work which led to the discovery and now work on finding cures for HIV/AIDS.


Stewart has participated in helping to organize several world summits including those focused on Global Warming and the Environment (Stockholm 1972), Rio de Janiero, Brazil (1992) and Johannesburg (2002).

In addition he has been a regular attendee since 1973 to the World Bank and IMF Annual Meetings, various summits of the WEF, the Crans Montana Summits, the Banff CEO Summits, and various CEO Meetings throughout the USA.

When companies find cultural roadblocks, political impediments, retro-active financial controls and unethical attempts to change prior agreements, hundreds of millions of dollars of investments can be lost.

He makes best efforts to avert these disasters by negotiating alternatives to these potential meltdowns. This is done directly with Heads of State and on behalf of corporate leaders outside the countries of operation.

Diplomacy and the normal rule of law involving traditional methods of negotiation have long since been proven outmoded and incapable of finding solutions to many of these problems.

Issues including corruption, retro-activity, mismanagement and differing levels of competence in various governments of emerging markets have produced dramatic challenges to most companies attempting to access the Third World.


High Level Government Negotiations at the Head of State Level Stewart has created methods of inducing sanity back into these negotiations and restoring the calm and stability needed to perform long term development projects. This is done at the highest level, face-to-face and between the principals involved. Large corporations have long lead times to make major changes in their market plans.

By the time these plans hit the markets, changes may have taken place in both governments and national economies. Finding swift answers to avert financial disasters are often needed. Co-operation and understanding of these challenges across wide political and cultural divergences are found.

This takes rare and unique insight into dozens of counter-veiling market forces. International Operations today demands a strong concerted effort to view every problem from dozens of different perspectives.

Stewart has developed a unique methodology for confronting the major challenges of our time, whether they are strategic, financial, security-related, or introducing new technologies into the market place.  


Stewart has taken on a very wide spectrum of challenges from negotiating nationalization decrees, securing investment proposals, raising billions of dollars of debt and equity finance, setting up major trade projects, vetting the due diligence of various governments and companies, insuring the safety and success of hard-earned business throughout the world during these turbulent times.

No risk or challenge is too great for Interop. We have done our homework, made personal and corporate contacts at the highest levels in over 100 countries and recorded some of the most dramatic financial successes on behalf of many corporations.

Stewart is a global consultant/CEO specializing in developing projects including new technologies in aviation, building major infrastructure, hotels/resorts, mining, petroleum and  high tech industries such as telecoms and aerospace. Specializing in the concept of Master Plans, he has worked with the world's largest engineering, construction and financial firms to build  and implement many major projects shown on these pages.
