plus it's a bit difficult to place the hex vertical on the exhaust pipe of the care don't u think ?

Discussion Overview
The discussion revolves around the BMW turbosteamer concept, focusing on its operational mechanics, potential challenges, and design specifics. Participants explore theoretical and practical aspects of using exhaust heat to generate steam for turbine power, as well as the implications for vehicle efficiency and system reliability.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants question whether the heat from exhaust gases is sufficient to instantaneously boil water, suggesting that a liquid trap may be necessary to prevent liquid phase ingestion into the turbine.
- Concerns are raised about the variability in turbine speed and the potential need for a continuously variable transmission (CVT) to manage the connection between the turbine and the crankshaft.
- There is a discussion about the efficiency of different methods for heating water using exhaust, with suggestions including wrapping copper tubes around the exhaust pipe or using a radiator.
- Participants express uncertainty about the design of the turbine, particularly regarding the feasibility of modifying a turbocharger for this application.
- Questions are posed about the source of makeup water for the system, with some suggesting that condensation from an A/C unit could be a potential source.
- Concerns about leaks in the system are discussed, with participants noting that plumbing can wear out over time, especially in steam systems.
- One participant proposes that the steam turbine could be used to recharge a battery, allowing the internal combustion engine (ICE) to focus solely on providing torque to the wheels, while also noting potential issues in colder climates.
Areas of Agreement / Disagreement
Participants express a range of views on the feasibility and design of the turbosteamer concept, with no clear consensus on the effectiveness of proposed solutions or the practicality of the system in various conditions. Multiple competing ideas and uncertainties remain throughout the discussion.
Contextual Notes
Limitations include missing details on the specific design of the turbosteamer, assumptions about heat transfer efficiency, and the implications of varying temperatures on system performance.
