Aneutronic fusion would be a game-changer.

A 2-cycle ICE hybrid

5/27/25:

 

You could make them out of superwood! 80% lighter than steel, and moldable into shapes fitting for an automobile, superwood could make the cars that much more efficient.

 

5/25/25:

 

The engine described on the main blog may be useful in several ways. It is a powerful engine in a small package. Therefore, it would not need a massive frame to hold it. It could be optimized to make just enough power to keep the batteries charged in a hybrid engine.

 

The engine in the video was about half a liter, with a power output of 200 hp. You could get away with a much smaller engine. Let's say 1/2 the size and output. That would mean a 250 cc engine with 100 hp. That 100 hp engine could power a generator, which in turn, would power an electric engine.

You wouldn't have to run it all the time. Just long enough to charge the batteries. With the new batteries coming out soon, you wouldn't need much weight on them either. They could also be charged an indefinite number of times, since they would actually operate more like a capacitor than a battery.

The engine would be quite versatile, since it could run on a variety of fuels. The ones mentioned in the video include hydrogen. Perhaps it could run on ammonia? In that case, if ammonia could be synthesized economically, it could replace carbon based fuels. Not that I would think that important, but some people believe in the global warming theory.

Anyway, I would speculate that a super efficient ICE hybrid may be feasible in the near future. Question is, will it ever be built?

Potentially revolutionary propulsion system.

 

Seems like I've heard about this design before somewhere. Once you acquire enough speed, the sky is the limit. Imagine a single stage to orbit aircraft that can take off from a runway. It would be air breathing, which could remove the need to carry oxygen. Oxygen could represent the lion's share of the mass needed to get to orbit.

JP Aerospace tests their home-made submarine

 

The video below was published just prior to a test of the sub...

... and afterwards a post on the blog about it. Not many details, but those may be forthcoming.

Installation of Fedora Linux distro

5/16/25, 6:34 PM::

 

I'm going to suspend this for awhile. Reason being that there's not good enough reason to add yet another distro to the collection. If Mint craps out again, maybe...

 

Just added a restore version on Mint, so if it does crap out, then at least I can try a restore option. Didn't have that the first go round.

 

2:39 PM:

 

Note to self: Installing Fedora via Live Environment installation disk will not work. Insufficient disk space. Well, duh.

 

So I had to do a real install of Mint, which is always an adventure. As of this writing, Mint is now re-installed. What happened to the first install?

 

Just say it got discombobulated and there was no backup or restore capabilitity. So I did without it for awhile until now, when I decided I might need it again. Trouble is, I forgot how I got the thing installed the first time. Always a fun time to rediscover how all of this was a pain in the arse.

 

Maybe I can install Fedora now. This post is made in the Mint environment, so that's poof proof. The last time I tried this, I was in the mint install environment, and google yanked the post.

 

5/15/25,6:50 PM:

Fedora may be simpler, but getting Linux Mint installed again is a bit of a tussle. Spent the better part of today working on this.

Why did I ever start bothering with computers???? Seemed like a good idea at the time.

This is a video which shows how to install the Fedora Linux distro. I've used this YouTube Channel (AgileDevArt) for videos on how to install other Linux distros, among which is Zorin OS. My impression of the video is that the installation of Fedora seems relatively simple in comparision with Zorin or any other Linux distro that I've installed. Perhaps this is a good sign. As of yet, I'm only considering this new (to me) distro.

P.S., 11:11 AM:

This video isn't the SilverBlue distro mentioned on the other blog. AgileDevArt installed it via Windows. I'm contemplating doing it through Mint. That's a difference.

POGO oscillation theory as to cause of Starship's recent RUDs

An unofficial explanation for what's going wrong with the Starship's recent flights.

 

Floating to orbit on Mars?

JP discusses a tandem airship. However, there's a better idea with his airship to orbit concept employed on Mars. However, there's nothing wrong with idea of using the tandem airship to launch a rocket with Mars samples to a waiting spacecraft for a return to Earth.

 

But there won't be any takers, unfortunately. There's nobody who would fund this, in my opinion.

Construction ideas

 

Drill technology for geothermal heat pump

The device enables the use of pretty stable temperatures below ground level. Such a "heat pump" will only take the relatively constant temperature below ground, and move it into ground level structures in order to facilitate climate control. A heat exchanger and air pump is about all that would be needed, but that really isn't discussed in this video. The video is about the drill tech.

 

I like the concept.(the drill tech)
