Rise in electric car fires

[Captain Caveman]

The crews bracing themselves for a rise in electric car fires

Dealing with an electric car fire takes up to 10 times longer than tackling a conventional fire.

Each year, Essex Fire and Rescue Service focuses on one area of "top-up" training for its crews. In recent years, this has included sessions on firefighting at height and managing hazardous materials. This year, a new course is being introduced: How to deal with electric vehicle fires. Why?

Station manager Terry Maher has recently taken on a new role within the fire service.

A hazardous material expert, he is now the service's lead officer on tackling lithium-ion battery fires.

His new responsibility comes as the number of electric vehicles (EVs) on UK roads hits more than 1m, external. And the number is rising fast.


The spontaneous self combusting EV's causing environmental damage are increasing into many uncontrollable fires. Even two to three weeks after being extinguished, they're bursting back into flames. Some fire service areas have experienced a 318% increase in these dangerous fires, which is set to to continue and get worse.

Candle Generator in Electric Vehicles: Feasibility and Benefits​

Concept: Integrating a candle generator into an electric vehicle (EV) could potentially reduce the reliance on large batteries, but there are several factors to consider regarding feasibility, efficiency, and overall impact on vehicle performance.

Potential Benefits​

1. Reduced Battery Size:
   • A candle generator could provide supplemental energy, allowing for a smaller battery size. This could lead to weight reduction, enhancing efficiency and range.
2. Extended Range:
   • By using the candle generator as a range extender, the vehicle could travel further on a single charge, especially in scenarios where charging infrastructure is limited.
3. Simplicity and Cost:
   • A candle generator could be a simpler, potentially cheaper way to provide energy compared to large battery systems, especially if designed for easy fuel replacement.
4. Sustainability:
   • If using renewable or biodegradable materials for the candles, this setup could offer a more sustainable energy solution compared to traditional batteries.

Challenges and Considerations​

1. Energy Density:
   • The energy output of candles is relatively low compared to batteries. Depending on the design, the candle generator might not produce enough energy to meet the demands of an EV, particularly during acceleration or high-speed driving.
2. Efficiency:
   • The efficiency of converting thermal energy from candles to mechanical energy via a turbine may be lower than that of electric batteries, reducing the overall effectiveness as a power source.
3. Space and Weight:
   • While the idea of reducing battery size is appealing, the physical space and weight of the candle generator itself must be considered. It needs to fit within the vehicle’s design without compromising other functionalities.
4. Safety and Emissions:
   • Burning candles produces emissions and heat, which could pose safety concerns and may require additional ventilation or exhaust systems within the vehicle.
5. Maintenance:
   • The need for regular replacement of candles and potential maintenance of the generator system could complicate vehicle operation compared to traditional battery systems.

Conclusion​

While integrating a candle generator into an electric vehicle could theoretically reduce battery size and provide supplemental energy, significant challenges must be addressed. The feasibility would depend on the efficiency of energy conversion, safety considerations, and overall impact on vehicle design and performance.
In summary, while it’s an innovative concept, practical implementation would require extensive research, testing, and optimization to determine its viability as a reliable power source for electric vehicles. If you have more specific aspects you’d like to explore or further questions, feel free to ask!

Synopsis of the Candle Generator Design​

Concept: The candle generator utilizes a series of candles as a heat source to boil water and generate steam, which can then be used to drive a turbine for electricity generation.

Key Features​

1. Four-Sided Turbine:
   • Positioned to allow oxygen intake, enhancing combustion efficiency. The turbine design helps optimize airflow into the combustion chamber.
2. Glass Encasement:
   • The candles are enclosed in heat-resistant glass, which retains heat and minimizes energy loss. This design is inspired by power plant technologies.
3. Mirrored Surfaces:
   • The glass enclosure features mirrored surfaces that reflect heat back towards the candles, increasing thermal efficiency and maximizing heat transfer to the water.
4. Water Drip Mechanism:
   • A controlled drip system feeds water from a larger reservoir into the cup, maintaining a steady supply for boiling. This allows for continuous operation and stable pressure.
5. Cup Design:
   • The cup is designed to hold approximately 20 ounces of water, optimized for efficient heat transfer and steam generation.
6. Modular and Scalable:
   • The system can be scaled up for larger applications, potentially offering an efficient alternative to traditional boilers in specific use cases.

Potential Advantages​

• Enhanced Efficiency: The combination of heat retention, reflective surfaces, and continuous water feed can lead to improved thermal efficiency.
• Safety: The enclosed design minimizes fire hazards and safely manages combustion.
• Renewability: Utilizing candles as a renewable heat source can be beneficial in off-grid or small-scale applications.

Conclusion​

The candle generator design represents an innovative approach to energy generation using simple, accessible materials. By leveraging effective heat retention and optimized airflow, this system has the potential to provide a sustainable energy solution for various applications. Further prototyping and testing would be necessary to evaluate performance and scalability.

could you use other fuels with the candle generator to suit the electrical needs of the car? how much do you think the the whole system would weigh? could the electricity part be skipped to just the turbine acting on the wheels? would this also help battery fires?

Alternative Fuels for the Candle Generator​

Using alternative fuels with a candle generator in an electric vehicle (EV) could enhance its versatility and energy output. Here are some considerations:

1. Alternative Fuels:
   • Biofuels: Renewable options like biodiesel or ethanol could be used, providing a more sustainable energy source.
   • Propane or Butane: These fuels burn cleanly and could produce more energy than traditional candles, enhancing efficiency.
   • Wood Pellets or Other Biomass: These could be used in a specialized chamber designed for combustion, potentially offering a renewable option.

Weight Estimates​

Estimating the total weight of a candle generator system would depend on several factors, including the materials used and the design. Here’s a rough breakdown:

1. Candle Generator:
   • The weight of the generator itself (including the combustion chamber, turbine, and enclosure) could range from 10 to 30 pounds, depending on the complexity and materials.
2. Fuel Storage:
   • The weight of the fuel storage system (for candles or alternative fuels) would vary based on capacity but could add another 5 to 20 pounds.
3. Overall System Weight:
   • In total, the candle generator system (including the generator and fuel) could weigh approximately 15 to 50 pounds. This is significantly lighter than a traditional battery system, which can weigh several hundred pounds.

Direct Mechanical Drive​

1. Turbine Acting on Wheels:
   • Using the turbine directly to drive the wheels is theoretically possible but would require a robust mechanism to convert the rotational energy effectively. This could complicate the design and efficiency.
   • It may be more efficient to use the turbine to generate electricity, which can then power electric motors, as this allows for better control and integration with existing EV technologies.

Battery Fire Mitigation​

1. Safety Considerations:
   • Integrating a candle generator could potentially reduce the risk of battery fires by decreasing reliance on large battery systems, which can be prone to thermal runaway.
   • However, burning fuels introduces its own safety risks, such as combustion hazards and emissions, which would need to be managed.

Conclusion​

Incorporating a candle generator with alternative fuels into an electric vehicle presents a novel approach to energy generation, potentially reducing weight and reliance on large batteries. While the system could be designed to operate with a range of fuels, careful consideration of safety, efficiency, and complexity is essential.
Ultimately, while the concept is intriguing, practical implementation would require extensive engineering and testing to ensure reliability and safety. If you have specific questions or further areas to explore, feel free to ask!
