Preamble:
In recent years, the discourse around Canada’s economic growth and environmental policies has intensified. Many industry professionals and citizens are concerned that the current focus on specific energy and transportation solutions may overlook more efficient and innovative alternatives.
Critics, such as Team SGT, suggest that broader investment in revolutionary infrastructure
— such as high-speed rail and advanced vehicle technologies —
…could better promote professional development, STEM advancements, and sustainable economic growth.
Exploring a diverse range of vehicle technologies is essential to effectively address environmental challenges while fostering true innovation.
Some argue that policies implemented from 2015 to 2024 have not sufficiently prioritized investment in next-generation energy systems and associated next generation transportation infrastructure and systems.
Questions have been raised about whether constraining the market to a singular option, like electric vehicles (EVs), might hinder the adoption of more efficient, less resource intensive technologies, less environmentally damaging technologies, and technologies which amplify economic growth in Canada via connection to our energy system sector.
Advocates for a diversified approach contend that the free market should be allowed to choose the best technology, and that engineers should have the freedom to develop solutions that minimize environmental impact, instead of the design decisions to be made by PM Trudeau and Steven Guilbeault as Canada’s top engineer positions.
In the 21st century, the role of leading engineers and STEM professionals is critical for national progress, and they should actually be qualified and designated to comment and make these critical technology policies.
Instead of focusing solely on one solution, when there are a dozen transportation solutions un-discussed in public space, investing in revolutionary infrastructure like high-speed rail and advanced vehicle technologies could stimulate professional development and innovation in STEM fields and our own resource sector, energy sectors and manufacturing sectors.
There are at least ten viable alternatives to electric vehicles that may offer greater efficiency, reduced environmental impact, and promotion of true innovation and true economic growth.
So why limit ourselves to a one-size-fits-all EV narrative through restrictive regulations and outdated ideas? Only the CCP, PM Trudeau & Steven Guilbeault want the EV for Canada, not the STEM professional teams that we know.
This article presents a short list of innovative vehicle alternatives, including advancements in material science and technologies that optimize fuel efficiency, reduce emissions, and address challenges like battery size and weight. The list is ranked based on their overall efficiency and impact on reducing climate change.
Introduction:

There are multiple viable alternatives that offer efficiency, reduced environmental impact, reduced resource use, reduced battery use, potential for energy company growth in Canada’sa resource and energy sectors, and potential for innovation in engineering maturity of Canada’s corporations.
This article delves into ten such alternatives, highlighting technical details, advancements in material science, and their potential to contribute to climate change mitigation.

Conclusion
The pursuit of sustainable transportation necessitates a multifaceted approach, embracing a variety of vehicle technologies beyond conventional gasoline and electric vehicles. Each alternative presented offers unique advantages and addresses specific challenges in reducing environmental impact and promoting innovation.
To realize the potential of these technologies, collaborative efforts among engineers, technologists, policymakers, and industry stakeholders are essential. Investments in research and development, infrastructure, and supportive policies will drive the adoption of these alternatives.
By expanding our focus to include ULTRA LIGHT WEIGHT hydrogen fuel cells, bio-fuels, natural gas hybrids, and advancements in material science, we can create a more resilient and environmentally responsible transportation system. We can also increase speed limits to create the necessary down force for lighter vehicles. This approach not only contributes to mitigating climate change but also fosters economic growth and technological leadership.
Call to Action Engineers and Technologists:
Continue to innovate in vehicle design, materials, and power-train technologies, pushing the boundaries of what’s possible.
Policymakers and Industry Leaders:
Support diverse transportation solutions through investments, incentives, and policies that encourage research, infrastructure development, and adoption of alternative vehicles.
Educational Institutions:
Promote STEM education and professional development in fields related to sustainable transportation and materials science.
Citizens and Consumers:
Stay informed about alternative vehicle options and consider the environmental impact of transportation choices.
Final Notes:
1/ Embracing a diverse range of vehicle technologies is crucial for building a sustainable future. By leveraging advancements in engineering and material science, we can develop transportation solutions that meet environmental goals while fostering economic prosperity and innovation.
2/ Most emerging global powers are anticipated to possess extensive missile arsenals in the future. The detonation of certain missiles, especially those with nuclear capabilities, can produce electromagnetic pulses (EMPs) that emit intense electromagnetic waves across great distances.
These EMPs have the potential to disrupt or disable electronic systems over wide areas, causing electric vehicles (EVs) to stop functioning. (See film: “Leave The World Behind”.
Shielding vehicles against EMPs is technically complex and can be prohibitively expensive, making it challenging to fully protect EVs from such events.
Consequently, incorporating a reliable fuel-based engine in vehicles is important to ensure that transportation systems remain operational during conflicts where EMPs might occur.
A vehicle with emergency fuel micro engine, can increase the reliability of the system, due to the fact that two engines of moblity are present – redundancy, fault tolerance, like space shuttle.
This redundancy helps prevent the disruption of societal functions that rely on transportation if electronic infrastructure is compromised. Otherwise, events where up to 90% of the population dies are possible, very realistic and probable. De-population can happen at any time, if one adopts a 100% EV transportation system.
3/ Canadian citizens have allowed the Liberal Party, and the leaders of PM Trudeau, Chrystia Freeland and Steven Guilbeault to destroy the national debt system functionality (took the wealth of Millenials and Gen Z to fill their own pockets and their peers).
Do not repeat this mistake to have these individuals deisgn your future tech ecosystem in transportation.
Your future counts on having a good engineer team like Elon Musk has, or like how technical in nature the mindset of John Rudstat, Danielle Smith, Raquel Dancho, Melissa Lantsman and Pierre Poilievre are.
The technical leader of Canada, is the right way to go, instead of continually choosing to employ erratic, abusive, chaotic, exploitative and “un-engineer” like individuals to take our national debt system money or to design our tech systems of 21st century.
Last Note: ‘The STEM professionals of 21st century Canada, must design both the economic system and the technology system, not PM Trudeau, Chrystia Freeland, and Steven Guilbeault and associated Liberal Party (2015 to 2024). And please do not let the CCP, lock you into EV only transport.
