Turbine alternator

Gold Member Username: JtownTexas Post Number: 3773 Registered: Mar-07 | yeah I immediately thought of an empeller when I read this title. that could be a good idea. |

You wouldnt want a turbo alt due to all of the heat, its bad for the electrical components. I have seen a few set ups where the alt is mounted on the rear axle and driven by the drive shaft. But then your alt only powers up when the car is moving. |

Possibly solar panels molded into the roof of the car. Ideal if you have a reasonable commute to and from. The cost of producing these panels right now however doesn't make it appealing to the mass auto industry. Not to mention most plants are down sizing or closing the doors altogether. The thought of retooling the assembly lines is just.......not happening today. Plus with the average cost of silicon solar panels at or above $5-$7/watt they are a thieves delight. Regenerative braking has been around for quite some time though but has only had minimal impact on the charging of the vehicle's batts. When it comes to alternative energy it will always be cheaper to conserve a watt than produce it. This concept is meaningless to car audio guys lol but if you looked around even your own electrical system you will see power hogging issues and components dragging your batteries down further than necessary. Undersized cables and even miss calibrated amps draw more than they should. They're your watts. Why not keep them?  |

Gold Member Username: Van_manBoston South, MA Post Number: 4885 Registered: Mar-06 | I have thought about something like that. But basically a turbine wind mill thing mounted in the grill with a air flow channel to turn the turbine, which would turn a small genset to supply electricity to the battery. This would be supplemental to a alt, so that the alt would only need to work at low speeds or higher current demands.  Also it would supply power to 32 sets of speakers.... |

Gold Member Username: JtownTexas Post Number: 3776 Registered: Mar-07 | seems just as cumbersome, to me, as an alternator. I like the idea of an empeller. only problem is low idle voltage. just a thought, maybe the intake can be utilized for idle? 1000rpm is still quite a bit. |

Silver Member Username: Armykyle1Ms Us Post Number: 695 Registered: Dec-08 | well exhaust turbos to generate heat buttttttt some of heat is generated by the air being compressed why do you think super chargers have intercoolers? Plus the further you get from the engine the cooler the exhaust is, ever noticed that you can hold you had over the exhaust tip? So in my opinion an exhaust back turbo alt would be ideal. It will spin a lot more rpm's than engine will. |

Gold Member Username: JtownTexas Post Number: 3778 Registered: Mar-07 | intercoolers aren't necessarily required. they do help, but you don't NEED an intercooler. if you're talking about heat, do you realize how much HP you lose, just to radiant heat? it's staggering. an intercooler actually negatively impacts air flow. which also takes away from HP. anyway, I see what you're saying, but using an intercooler for a empeller driven "alternator" would almost be pointless unless you can figure a way to get that "cooler" air into the "alternator" to help with electronic efficiency. |

Gold Member Username: JtownTexas Post Number: 3779 Registered: Mar-07 | sorry i missed the last part, an exhaust back turbo, as you call it, I don't think would be very efficient as you aren't generating enough air flow/pressure to spin the alternator significantly to charge the battery. |
|
Gold Member Username: JtownTexas Post Number: 3780 Registered: Mar-07 | I'm drinking, sorry I'm only reading thirds of your post. you're going to get a greater amount of air flow during intake than you will with exhaust down the line. air flow is negatively impacted by cold air, so if air flow is the issue, then an intercooler wouldn't be necessary, for this alternator. In my opinion. |

Silver Member Username: Armykyle1Ms Us Post Number: 699 Registered: Dec-08 | lol thieves you assume too much, I'm not saying you NEED an intercooler or was I saying use an intercooler with a turbo atl. I brought up intercoolers to show that not all the heat is from exhaust gases but the heat generated by the air being compressed. this is why exhaust back turbo systems such as the STS systems don't have intercoolers. I almost guaranty that your muffler will get just as hot as your alt being under the hood maybe even cooler. This is a fantastic idea. And if heat becomes to big of a problem then have some kind of scoop to move air over it. |

Gold Member Username: JtownTexas Post Number: 3781 Registered: Mar-07 | I'm not talking about heat as far as your down the line exhaust idea, I'm talking about air flow and air pressure. I just don't see there being enough pressure to spin the "alternator" significantly to charge a battery. to address your post, I think some sort of empeller is the best bet, and if heat becomes a problem is electronic efficiency, then add an intercooler and observe the results. radiant heat is MUCH greater than heat created by the exhaust, your engine loses close to 51% of it's HP to radiant heat. The HP your vehicle is rated at is half of the actual HP, which you would see if not for radiant heat. |

Silver Member Username: Armykyle1Ms Us Post Number: 702 Registered: Dec-08 | I fully understand what you're saying about radiant heat, that's why a car will run like crap around town. But the topic at hand is this alt idea lol. At idle it wouldn't move much but once you got some pressure built up it should be fine. Also if eat is a problem the put a fan on the alt like older chevy's had |

Gold Member Username: DuckaHoughton and/or Macomb, MI United States Post Number: 1045 Registered: Jan-08 | While we are on the topic of inventions... How bout someone invents an electronic remotely adjustable aeroport. It could be low tech (where it just moves from a switch) or high tech where it is wired to a small computer that calculates tuning frequency based off of box volume, port width and length, and other factors. I really wanted to do this invention myself, but I dont see myself doing it. So all that I ask if someone does invent this is that they send me a couple free of charge.  |

Gold Member Username: Van_manBoston South, MA Post Number: 4889 Registered: Mar-06 | Thats been done, Sorta. It was in CA&E mag. It went from a ported to a sealed box with a solinoid activated switch. Also There is diagrams out there using relays to "rewire" your sub from say 1 ohm to 4 ohms with the throw of a switch. Combine those two for a daily and a street beat box from the drivers seat with 2 switches. |
