Kers (kinetic energy regeneration)

kmkraft12

That is a awesome idea for street cars. I had never thought about that.

While KERS is a great concept and several companies are bringing viable products to market, retrofitting KERS for performance gains would be a costly, complicated affair that would add considerable weight. One might be able to design/install a KERS MPG booster, but I wouldn't expect great power/performance gains from a homebrew system.


Edit: I'm not trying to talk anybody out of doing it - if someone can put a jet turbine in a VW, KERS in a 370Z is possible - just be aware that it is not the typical DIY project and will require a lot of engineering know-how.

They will likely adapt this technology in future road going sports cars, until then, its an extremely expensive exercise that's not guaranteed to produce any viable benefits. You're adding power, but the system itself adds weight a lot of unknowns to the car. A system similar to the one used in F1 could cost more than the our car considering the F1 gearbox run north of $130k each. There are easier and cheaper ways to add 80-100hp in 6 second spurts.

One look at the title of the thread and two it isn't regeneration. You don't recreate the energy. Energy cannot be created or destroyed. It recovers the energy. At least now I know ONE here knows nothing about physics or KERS.

kmkraft12

While I was exaggerating on the "no one knows anything thing" I don't think regeneration and recovery can be interchanged. Recreating and recovering are totally different things.

kmkraft12

Exactly and regeneration is (from dictionary.com) "to re-create , reconstitute, or make over, especially in a better form or condition." When KERS is used the energy is recovered during braking and used to produce more power. It does not regenerated energy. It never re-creates the energy. It takes one form and changes it, and puts it to use somewhere else. If you could regenerate energy then you breaking Einstein's law of conservation of energy. That is why it is a huge problem (when describing something as complex as KERS) if that specific word is used instead of recover.
BTW since you attempted to go all, I'm smart I know Hyperbole. Hyperbole is always inaccurate. It is a speech tool used to show a strong feel towards something it is not meant to be taken literally. Saying inaccurate hyperbole is like using a double negative. It makes you sound like a moron. I wasn't trying to create an argument here. I was trying to alert the OP that he should take everything he hears from the people posting with a grain of salt.

It is a widely accepted misnomer.

also, mixing Dictionary.com definitions with terminology specific to a field makes no sense.

elperuano

Da hell is the point of this thread???????

kmkraft12

Well since you failed to argue your point I guess you are saying that I am correct.
Also "I've been called a lot worse than "moron" by ppl a lot better than you." And your point. You basically said that multiple people have called you a moron. That's not really a good thing. Sorry I called you moron .

Red__Zed

Since you like the Dictionary.com definition above so much, why didn't you post the whole thing?


re·gen·er·ate
[ri-jen-uh-reyt; ri-jen-er-it] Show IPA verb, re·gen·er·at·ed, re·gen·er·at·ing, adjective.
verb (used with object)
1.
to effect a complete moral reform in.
2.
to re-create, reconstitute, or make over, especially in a better form or condition.
3.
to revive or produce anew; bring into existence again.
4.
Biology . to renew or restore (a lost, removed, or injured part).
5.
Physics. to restore (a substance) to a favorable state or physical condition.

I actually didn't see the other definition I am on mobile and it didn't show up. Although you did add the physics part at no point did it say physics. I still think that using regeneration is wrong though. I have never heard someone use the word regenerate to mean gather.

Red__Zed

sure it is. The capstone work I did that inspired my thesis was about the efficacy of supercapacitor arrays for regenerative braking.


I hope they don't take my degree away as a result of this thread.

kmkraft12

I agree about the use of a super capacitor for KERS in a road car. I think that because of the danger of fires during the use of them it is unlikely they will be used, it will most likely be mechanical in the future. But regardless did you really need to flash your degree. Lol. Also when did I argue against you thoughts about the use of super capacitors. I just wanted the OP to know that you aren't magically creating the energy it is being recovered from somewhere else. That is all I have said yet people a flipping out. I am not trying to argue I'm just trying to help out the op. As I said before he should be careful about listening to the people on this thread. Including me. All I know about KERS is what I have read. I am not an expert on it. I am just trying to add what I have read so that the wrong idea is not given. So please. Lighten up.

And lastly my most important part about the definition. Is it says to restore a substance to its original state. Is energy a substance. Didn't think so.

Red__Zed

Regenerative is a perfectly fine word to use to describe the system. You came in with an attitude, and I just pointed out it wasn't really a point worth arguing.

As far as your comment about fire risk from supercaps in a road car...they're certainly safer than the batteries hybrids run now, and Tesla doesn't seem to have any issues with them in their road cars.


Again, dictionary.com is not where I would go for definitions, and it is parenthesized for a reason.


Energy does have some substance like properties, though. It is actually a curious task to try to nail down the definition of just what energy is.
