New Device Turns Waste Heat into Electricity

[LMagic007]

No just enhancing the truth and I suspect your advice would be the last that anyone would heed. Ah more wasted energy. I better go plant a tree.

Don't we ?

Bear in mind that you are a moderator.

Have you finished editing yet?

Get over it. I'm just saving energy.

Yes I was hoping that would moderate him, but aparently nothing works it seems. Has anyone else had any success ?

In what way exactly?

Please use your imagination, though I note you didn't hesitate to re-post it as a quote, and you have not disagreed with it. Unfortunately it's sometimes more effective for some people to be shown by tabling of reverse of example of their own actions. I sincerely regret any offense that may have been taken, however sometimes this approach can be the only way some people realize the effect of their own medicine. Further more, moderation through conventional efforts has often been disrespected by an extreme minority, making the task of moderation almost futile at times. Most people react favorably to moderation, however this extreme minority appear to see themselves above it and react in an adversarial way, when almost anything they have posted is moderated by more conventional approaches. I guess the site admin has the final say on all matters, though even their job can be compromised by those individuals who are persistent enough. Now of course nobody has to agree with that view and that's fine too, but at least respectfully disagree, though I appreciate with the level of passion that exists with all greatly concerned about environmental matters, that it's easily to push the boundaries of civility. With that said, there are some with a well known reputation for their unique style of communication and interpretation of civility. Anyway this is getting off topic and best discussed seperately.

Thus to get back on topic New Device Turns Waste Heat into Electricity

I think that its good that man is looking for new ways to capture energy that would be otherwise wasted in addition to doing the common sense things that save energy. We can all do our bit in one way or another.

Since you haven't actually answered the question what is there to agree or disagree with?

I suppose that would depend on whether the moderation is seen as fair and appropriate.

And none of your posts is adversarial?

Wise counsel. We would ALL, without exclusion, do well to heed it.

As I posted elsewhere, I have been concerned with energy efficiency for most of my professional working life. Our approach has been to minimise losses which, of course, means higher efficiencies. If you can make a better, more efficient mousetrap, it will generate more sales. Contracts have been won or lost on the basis of a fraction of one percent efficiency difference. And, when full system tests are part of the contract, you can't fudge the figures.

So from the supplier's point of view, better energy efficiency generates more sales and from the customers point of view, it means lower energy bills. In both cases the driver is financial rather than an altruistic concern for the environment.

At the domestic level, maybe the same approach could and perhaps should work. If you can use more efficient kit that will save money then why not? If you can make your house better insulated and save money on heating....etc.

Maybe that's the way it should be promoted.

Adversarial is probably putting it mildly for that extreme minority. Perhaps just outright crude and rude.

Agreed. Anyway back on topic.

Indeed and yet we still waste heaps of energy through wasted heat in this world. Motor vehicle engines one prime example among many. Thus new ideas to tap waste heat are openly welcomed. This idea presented of converting heat to sound and via a piezoelectric device to electricity is interesting and if it can be implemented successfully, fantastic. Its just another tool in the kit bag.

Every angle of tackling wasted heat energy that can be reasonably be attacked, should be. That's my point, be it domestic housing and insulation, or tapping waste engine heat, or other methods of reducing heat loss, if methods can be effectively implemented and make a real worth while difference, they are worth pursuing. I hope the idea of converting waste heat into sound energy and then electricity can be shown to be a worth while implementation.

Rude and crude mean different things to different people and in different contexts.
In general, I don't get offended or upset by it.
A brief bit of UK history. Ken Tynan was the first to use the f-word on the BBC.It was in 1965 - yes, I remember it well. Of course it generated a lot of huffing and puffing and tut-tutting in various quarters. It even resulted in a motion of censure from Parliament. In retrospect it may seem like a huge over reaction but in the context of the standards of the day, possibly not - many subjects then were just not discussed in public. Repressed, one might say.

Billy Connolly wrote a song about it. "The Four Letter Word". The only bit I can remember is his comment on the old ladies' attitude to the f-word.
"They've not only said it, they've done it as well."
Kinda puts it in context.
In short, although I don't generally use profane language, I don't get particularly upset if others do.
Personal derogatory comments about other posters, profane or otherwise, is more to be deprecated.

Sure, IC engines produce a lot of waste heat through the exhaust gasses, cooling systems and transmission. In a motor vehicle installation the options for recovery of waste heat are somewhat limited. It's a stand-alone system. For this application waste heat is a nuisance, not a resource.

Yes, if it can be. Until it is, it is not a tool in the bag.

Symko expects these devices could be used within two years

Could be. Not is.

Obviously. Spare the history lecture. It's not just about four letter words. That's overly simplistic.

Exactly and there is one individual in particular, who indulges in it almost as routine. This really getting way off topic and not the forum to be discussing it at great length. The topic is best left for the appropriate forum room. The point was made long ago.

Conventional vehicle engine design wastes a ridiculous amount of heat and to capture that heat presents a tremendous opportunity. In the bag or otherwise, it's a worthy pursuit that can benefit current, evolving and emerging technologies, particularly the hybrid and electric vehicle technology. The limitations are largely limitations of the mind and invariably man tends to evolve beyond the prevailing mindset, when the necessity is there and the necessity has truly arrived.
