In the field of EEU design and optimization, SMG is well known internationally.

Around 1980, SMG published (see below) some unique and outstanding design procedures in international journals such as “Energy” and “Solar Energy”.

These design procedures, called seminal by the journal editors,  have never been equalled.

Using mathematical modelling techniques and solvable differential equations, SMG replicated and superceded the mainframe computer simulation work of groups such as the US Energy Research Institute, Los Alamos Labs, University of Wisconsin, University of Waterloo and Colorado State University.

Those SMG publications were in the areas of solar heating and cooling, passive solar energy, and seasonal storage systems.

The SMG methodology for deriving mathematically solvable models of these systems including annual hourly temperature and solar radiation data, and building configuration and device parameters is generic.

The techniques which reduce computing times conservatively by factors of 100 to 1000 can be applied equally well to other types of active and passive EEU devices and systems, including, but by no means limited to concentrators, photovoltaics, building energy management, water source heat pumps, and all types of energy storage including batteries (for cars, houses…), fuel cells, district energy, and industrial processes like desalinated water.

The results of SMG system performance analysis and design are in an analytic form (transcendental functions) that is particularly useful for LCC analysis which is the final and most important test of EEU design.

Rather than continue to produce more publications, conservatively estimated to be 100 or more, SMG has chosen to privatize, protect, and monetize the remainder of this outstanding IP.

In light of the rebirth of commitments to sustainability, and the current exponential growth of the renewable energy marketplace, SMG is again seeking angel investors and businesses that can help optimize the value of this IP, conservatively estimated to be 50-100 million$, to all interested parties.



For all of the following work that includes his name, Dr. M.S. Drew was partially supported by an NRCC IPDF working under his advisor Dr. R.B.G. Selvage. Dr. Selvage’s NRCC mandate was to teach his IPDF’s how to apply their STEM skills outside the University in the business world.

For many years, the BC Science Council also provided Industrial Fellowships to SMG personnel with MASc, MSc and PhD degrees to train under Dr. Selvage to learn how to work as applied STEM contractors and consultants in the non-academic world. Many worked on the projects described on the SMG website.

SMG has also worked for many years, and continues to work successfully with the SFU and UBC student co-op programs. Some of the best work by SMG has been done with the assistance of all of these programs.
