Re: Housekeeping

For SpaceNut re 3675

Thanks for the good news the internment is complete, and that your sons came to help.

Thanks too, for the good news the pallet project is continuing despite the soggy weather.

Thanks for the detail about the daughter you lost some time ago.

Re: Housekeeping

For SpaceNut ....

Sometimes it is worth while to read the definition of a term, before commenting upon it.

We have talked about sand but adding liquid now creates internal tank storage pressure. Sand battery was discussed in the Geothermal and Geothermal Battery (Changed Title 12/21/23) a Void started topic.

Your comment reveals you do not understand what is going on.

There is no "fluid" other than plain air.

The "sand" is not sand as we think of it.

Please take time to read the explanation I provided.

Re: Housekeeping

This is the system that I described for solar concentrated with antifreeze heat exchanger embedded in the sand so that heat can be taken out later for heating.

Re: Housekeeping

For SpaceNut .... thanks for additional information about a traditional sand based storage system.

Is the picture valid for a "fluidized" system that uses air to circulate the material, which is NOT "sand" in the usual beach sense we might think of.

In your post about a traditional sand based energy storage system, you asked what happens if a pipe leaks?

The answer would appear to me to be universal, for any kind of heat exchange system.   The pipe has to be repaired.  The nature of the material used to hold thermal energy has nothing to do with repair of a pipe.

If you can find something about the actual system of the topic, please post it.  All the other material is better applied to other topics.

Re: Housekeeping

For SpaceNut re Google Meeting....

I am looking forward to next week, in hopes you can show us more of your progress on the pallet shed.

In the mean time, kbd512 has made significant progress in moving the new FluxBB system toward testing.

We are able to access the system from the outside Internet, and the formatting of the color scheme for PHP files is not yet correct. However, we seem to have the restored database from September 9th in place, and the functionality we tested worked.  However, we did encounter a problem that prevents us from releasing the system for testing. Whatever the problem is, it is unique to the Mars Society configuration, because we have the exact same software running on the Azure test site, and on my development PC and the problem is NOT present.  I am hoping kbd512 will find time to investigate over the next week.

In other news.... you may have noticed RobertDyck has initiated an interesting topic about fusion, and kbd512 found a reference to a fusion rocket that seems to have one or two aspects that seem similar to what RobertDyck is considering.

In still other news, RGClark and GW Johnson recently exchanged posts that included a reminder of the Cold War, and out of that came a suggestion from GW Johnson to take a look at back issues of Aviation Week magazine, which has been published since 1919.  The entire series appears to have been digitized from about 1919 through about 1963 or so.  I took a look at an issue from 1919, and was amazed at the dramatic experiments in progress at the time.

Re: Housekeeping

For SpaceNut re How are things going?

GW Johnson tells me that the present time may be challenging for a gent who lost a spouse.

The first week is filled with activity and this week you've been busy catching up at work.

You're welcome to stop in tomorrow evening if you'd like.

Re: Housekeeping

For SpaceNut ...

Thanks for stopping in with the Google Meeting Sunday evening....

This topic title seems appropriate for the massive rework you are doing to renovate the home where you and your family have lived for quite a while.

Thanks for showing us the interior where you've been working, assisted by your sons, and giving us a sense of your plans for a new roof and other needed improvements.

Best wishes for success as you proceed with this work, and for the best possible answers to questions that come up as you proceed.

Re: Housekeeping

For SpaceNut ...

This topic started out as a place for discussion of housekeeping for the Forum.

However, in recent days it has unexpectedly opened up to a ** real ** house ** rebuilding ** project that you have started there in New Hampshire, but which you have a strong incentive to finish before winter.

The highest priority may be the new roof.  Have you made a decision if you are going with metal (50 years) or asphalt (30 years)?

Update:
SpaceNut, you may have perfect hearing. I hope so.

However, I've taken an interest in the subject of hearing, and found this article of interest:
https://www.nytimes.com/2024/10/18/dini … wtab-en-us

The article is about experiments by Apple to provide hearing assistance.
