SUMMARY
Mechanical Engineer and Physicist with work in New Product Development, Thermal Engineering.
ACHIEVEMENTS
PhD Thesis research on Transport Properties of Electric Arc Plasma, at University of Minnesota, USA, and RWTH Aachen, Germany results in industry standard computer code for the design of circuit breakers, steel making arc furnaces, and welding equipment.
Invented Floating Plate Gas-to-gas Heat Exchanger for high temperature applications; weld-free construction permitted use of high alloys and ceramic materials; numerous units sold by the company for heat recovery and process applications.
Invented and developed the Alex condenser, an air-cooled steam condenser for power plants; scaled-up application of automotive radiators heat transfer geometry results in enhanced power cycle efficiency; reduced condenser size and cost of materials; novel method of soldering in one step extra-large bimetallic steel-aluminum tube bundles.

WORK HISTORY
GEA Group Aktiengesellschaft, Bochum, Germany - 1995 to 2012
Multi-national supplier of production-process technology and components focusing primarily on the food and energy industries.
Position: Director of Research and Development.
Overseeing all stages of New Product Development from concept creation through to commercial launch. Leveraged small in-house development team of 6 by securing cooperation with outside university research groups and contract suppliers of tools and equipment. Collaborated closely with engineers in company laboratories and test facilities. Designed test procedures, thermal calculation methods and computer programs. Reduced development cycle time frame by application of CAD, FEA, CFD and virtual prototypes. Conducted tests including field tests of the final product and performance measurements. Presented regular progress reports to company management. Made presentations to potential customers beginning early in the development cycle. Initiated the development marketing strategies in close cooperation with the public relations and marketing departments.
Major Contributions:
Invented and developed the ALEX condenser, an air-cooled steam condenser with enhanced thermal efficiency that eliminated large, unsightly cooling towers, decreased energy usage, and reduced condenser costs 30-50%. The development was based on a novel design concept and patented technology of soldering aluminum fins to large diameter steel tubes.
Reduced development cycle time and costs by use of engineering software packages.
Developed a one-step brazing process to fuse bimetallic steel and aluminium structures weighing up to 5 tons.
Collaborated with engineers at a steel mill in designing a production line for 6-inch flattened steel tubes with thin aluminum skin.
Designed and constructed a proprietary aluminium brazing furnace for extra-large parts in nitrogen atmosphere; managed the company’s construction force and outside suppliers.
ABB Lummus Heat Transfer BV, The Hague, The Netherlands - 1990 to 1995
EC firm for design, procurement and construction of heat transfer equipment for the oil refining, petrochemicals and power industries. Member of the ABB Group.
Position: Director Research and Development.
Design and development work on high temperature/high pressure reactors, ethylene cracking furnaces, steam reformers, HRSG systems and heat exchangers. Project management. Worked directly with company customers including Chevron, Shell and Exxon. Member of sales and contract negotiation teams.
Major Contributions:
Developed novel flat finned tube heat exchanger for process cooling of refinery streams.
Computer program for FEA analysis of creep behavior of high alloy reactor tubes to temperatures and pressures up to 1700 F and 600 psi.
North Atlantic Technologies, Inc., Minneapolis, Minnesota - 1985 to 1990
Producer of heat recovery systems for power plants and oil refineries; systems design, own manufacturing and field construction services.
Position: Chief Technical Officer.
Invented, patented and managed development of the first large plate gas-to-gas heat exchanger. Unique weld-free construction permitting utilization of high alloys and ceramic plate materials. Wide temperature range, from 2000 F down to near ambient. Major application is for heat recovery from large volume exhaust gases in oil refineries, petrochemical plants, food processing plants and utility power plants. Fuel savings of 20% or more. Technology marketed nationally and internationally under the product name OCAP. Company customers included Chevron, Shell, Exxon, ADM, Wisconsin Electric Power Company, many others. Several international licensees among whom Sumitomo, Japan.
Major Contributions:
Company founder
Product development all phases, first sale within one year
Thermal design computer program
Personally involved in strategic sales and marketing plan development
Project manager of larger systems
Continuous development of technology including additional patents
Combined Cycle Developments, Minneapolis, Minnesota - 1985 to 2012
Technology development company; this is the name under which I worked continually as independent contractor on projects outside the companies of my permanent employment and as permitted.
Position: Director Research and Development.
New Product Development and consulting services to existent companies and start-up ventures. Collaborate with former employers after completion of projects on the enhancement of previously developed technologies. Conduct field measurements and collect data for further product improvements.
Advice individuals and venture capital groups considering investments in new companies. Perform due diligence and produce reports on the merits of renewables technologies.
Contributions in the latest 6 years:
At Sierra Angels: Served as consultant to the Nevada-based company, which provides early-stage investments in technology ventures in the Northern Sierra region. Participated in new ventures including the American Petroleum Company for acquisition by American investors of petroleum assets in a privatization program, and Sierra Sciences a biotechnology company for human telomerase expression drugs.
At GEA Group: CFD simulation of a 200 MW air-cooled steam condenser; large air flow envelope (200 m), large diameter fans (10 m) combined with fine details of the heat exchanger including two-phase flow. Optimization of the control system function of ambient conditions of temperature, humidity and wind. Improved controls lead to lower condensing temperatures and consequent enhancement of the thermodynamic cycle efficiency.
On my own: Following my long-term interest in health improvement/maintenance of the work force in organizations, and with my own funds, I developed a comprehensive software package for chronic disease prevention through improved diets.
Career Note: Previous professional experience includes theoretical and applied research in the fields of heat transfer, irreversible thermodynamics and plasma physics at several universities including the University of Minnesota, USA, and the University of Aachen (RWTH), Germany.
