Alternatife for alternator.

First of all: What will removing the alternater doing for FE?

I was thinking of removing the alternator and install something else. I've seen someone with 2 accu's and a solar pannel. But i think that's not efficient enough. Also got an garage so... no sun there

Than i thought. What's in the car that's useless... heat Now we get rid of the heat whit the radiator in front. But we also could use that heat. Heat equals energie. So i thought again (not getting an headake) about somethink like a sterling engine. I know sterling engine will only get 50% of the Carnot-Faktor but could it be enough for an alternator.

Also the heat from the exhaust could be used .

Good thing is that is don't have an A/C. Bad thing is that i always hear music

But were to find a small sterling engine?

For testing i thougt about to let the radio run fisrt on the stering and when that's doing good i will use it for the whole car.

Someone did this before? Or someone have an other idea how to use the heat for making power?

/edit somebody tried something whit a Thermogenerator? Just peltier-elements the other way. http://en.wikipedia.org/wiki/Thermogenerator It's called Seebeck-Effect. Transforming heat to energie. But don't know if i simple can use Peltier-elements.

The alternator is a significant load on a small engine. Removing it can be very good for fuel economy (~10% improvement isn't uncommon).

Have a look through these search results: lots of discussion of alternatives to using an alternator, including solar, peletier, etc...

I did my homework and found this topic.

I think the Tiger option should be the best, but i think it wil be expensife. But number 2 is like a good idea. Just use a bigger diameter to reduce rotations and by this better FE. But how much % wil it give? And how to make it?

I just came on a site called heat2power.net and found that there are some manufactures (like BMW) are making (testing) some kind of heat 2 power stuff. Like from the exhaust.

Now i was thinking about this:



So a smal pump is puming some liquid around. This liquid getting heated by the exaust pipe til reached boilpoint. Than it's going to a trubine and finally in a condenser to get liquid again. And the turbine just feeds the alternator.

This should be makeble. I only need some parts like a turbine and a condenser. A condenser is not hard to get, but where can i find a turbine?

Use the exhaust-side of a small turbo?

Hmmmm where to find one for cheap. The most turbo's i see are 200-400 euro and that's a little too much for this experiment. I don't want to spent a lot of money in something what maybe not working.

find one that needs rebuilt

junkyard a small stock turbo. No need to buy new.
