Are there any examples of a Stirling engine being enclosed with something to suppress the sound from it?

A lot of noise from a Stirling engine is not usually an issue as they generally run pretty quiet.

I would imagine those inside a cabinet for CHP units that might go in a home would probably have some sound/vibration suppression.

Thanks guys.

Can I ask for a weird favor? I must be doing something wrong but it seems I can not create a new post (despite having permission to do so), nor can I contact the mod/admin. I have cleared cache, deleted the board cookies, restarted, logged out and in again; disabled extensions. The main issue is that I can not type in main message layout itself. It looks blued/greyed out. What am I missing? Could someone please reach out to the admin and or mod on my behalf please? Or if someone can give me an email to send an email to. When I press Full Editor & Preview in thread message itself, it seems to somewhat work.

I also get this message when submitting

There has been problems, as you've described, with the forum the past few days.

I'm not able to use the administrator contact form either.

BTW a post above by ingridguerci94 is a spam bot post.

Ok thanks for letting me know.

Oh, how do you know it's a spam bot post?

The text is AI generated, scraped from the internet. It is from a PDF and a section that is actually talking about diesel engines.

Stirling engines don't have an exhaust, so can't use mufflers.

But if you reply (using quote) the quoted text contains a URL.

In some way the URL is hidden on the forum and only appears as a tiny light blue dot at the end of the post.

The hidden link is to an "adult" content site.

The "new member" joined some time ago, and posted an introduction, it appears these AI spam bots are becoming more clever and harder to detect.

I reported this a few days ago. Usually it would have been removed right away.

Perhaps reports aren't going through.

Tom it seems we're back in business :)

Not only were the bot removed, you can now post again, and it seems the phpbb board was updated.
