Why Building New Electric Vehicles Overrides Retrofitting Existing Ones with Solar or Electric Power
When it comes to transitioning the automotive industry to sustainable power sources, the debate often revolves around whether to build brand new electric vehicles (EVs) or retrofit existing vehicles with solar panels or electric power systems. While the idea of converting petrol vehicles to EVs seems appealing, the practicalities and limitations of such an approach often make it less effective than building new EVs from scratch.
Solar on a Vehicle: A Waste of Time
One common argument against building new EVs is the suggestion of fitting solar panels directly onto the vehicles. However, this idea is fundamentally flawed. Solar panels are intended for stationary devices, not for vehicles that are constantly moving out of the sun's direct rays. Houses, on the other hand, remain stationary, which makes solar panel installations more viable. Vehicles, especially cars, are too small and frequently move out of the sun's path, rendering solar panels inefficient for their energy requirements.
Converting Existing Vehicles to Electric Power: Just Not Practical
Another approach to transitioning vehicles is converting existing internal combustion engine (ICE) vehicles to electric power. While this idea might seem like a practical compromise, it involves a lot of unnecessary work and expense. Converting an ICE vehicle to electric requires significant modifications to the drive train, battery installation, and rewiring of the vehicle. This process often requires removing the entire engine cooling system, fuel systems, and drive trains, replacing them with electric components. Additionally, the structural integrity of the vehicle must be reinforced to support the additional weight and electrical components.
The end result is a much more expensive and less efficient vehicle compared to purchasing a new production EV. The cost to retrofit a vehicle can easily double the cost of a new EV, and the resulting vehicle may not even be as functional as a standard EV. Furthermore, the conversion process resembles a form of "hot rodding," where enthusiasts modify their cars extensively for performance, but it often results in a vehicle that lacks the advantages of both electric and non-electric power.
The Need for Vehicle Design Integration
For optimal performance of battery and fuel cell technologies, the vehicle must be designed around these systems from the outset. Retrofitting existing vehicles with electric power systems introduces numerous challenges that can compromise the vehicle's overall performance and efficiency. The entire engine cooling system, fuel systems, and drive trains need to be removed and replaced with electric components. Additionally, new mounting points and structural support are required to accommodate the added weight and electrical infrastructure.
Solar panels are currently not efficient enough to run electric vehicles on their own. While they can serve as a supplementary energy source, providing a trickle charge to the battery and extending the vehicle's range by a small degree, they are not sufficient for driving. The inefficiency of solar panels on moving vehicles, combined with the significant changes needed for an effective conversion, often makes this approach impractical in terms of time, cost, and practicality.
Hydrogen as a Viable Alternative to Retrofitting
One lesser-discussed approach is converting existing ICE vehicles to run on hydrogen fuel cells. Hydrogen fuel cell technology is a promising alternative to electric conversion, offering a cleaner and more efficient power source. While there are challenges to getting ICE vehicles to run on hydrogen, these can be addressed with the right advances in technology. An integral part of motor sport could support and accelerate the development of this technology, ensuring that the industry remains innovative and exciting to watch and hear.
Concluding, while the idea of retrofitting existing vehicles with solar or electric power seems appealing on the surface, practical limitations and inefficiencies often make it less effective than building new EVs from scratch. The automotive industry should focus on developing and integrating sustainable technologies from the ground up to achieve optimal performance and efficiency.
