Hi OK.

Like Hydrogen production, the whole idea is to use clean energy to make and charge batteries - large batteries are appearing as integrated elements...

There clearly appears to be a problem in storage and transport. After a search, wiki has some good ideas about all this, and the best solution right...

I don't know much about this, though I did read some years ago that metal hydrides were being investigated. I don't know where that has got to. My...

Vitrification of nuke waste seems to have the leg up on all other approaches. It involves trapping the waste in glasses at high temperature. The...

This seems unlikely because neutrons tend to make things radioactive, and radioactive isotopes from nuclear fission tend to be neutron-rich anyway.

No, I am not sure about it all. which is why I posted the thread, and get informed responses like yours and Ken's. The concept was stitched...

Yeah, you are right, that is a good point. Uncrewed missions are more secure and cheaper. That makes them more frequently used in space exploration...

Mentioning the last advanced space technology of the recent time, I`d like to say a few words about the first Uk-build Mars rover. In the mission...

Are you sure about this? The critical point for H2 is 33K. And to get liquid H2 at atmospheric pressure you have to cool it to 20K. Are there really...

Charging all those batteries on the existing electricity distribution systems is going to produce a lot of greenhouse gases, unless they are powered...

Examples? Rockets for launching to space are basically the same - better manufacture, improved materials and control systems and lower costs but...

I don't expect Hydrogen will become a major transport fuel any time soon - too much associated infrastructure would be needed. Besides overall much...

Yes, it seems that venting the fusion plasma would provide propulsion, but the mass of the propellant would be quite small (although this likely does...

This is so very true. One can only wonder how humans would have evolved without modern medicine. Considering our penchant for waging wars and...

The trick would be to create the conditions of a self-maintaining Fusion reaction without having to completely contain the plasma. Plasma would be...

I am fond of the way how microsatellites are developing and how they partially substitute ordinary sats. This is a cheaper and easier way for some...

An inconvenient truth is that humans have overpopulated the earth. But by the end of this century the population might be halved. Right now viruses...

"The Sword of Damocles" is an ancient anecdote about the perils of those in power. It is used here to denote the potentially fatal aspects of the...

Well, yes of course one has to have a functional fusion reactor. Its "size" for a spaceship will depend on the output vs. mass of the reactor and...

I didn't look at the blog, but I don't like the name.

Who was Dr. Damocles? I've never heard of him.

Pretty sure you have to discuss your ideas here as it is a discussion forum. I think your link will be deleted so you might think about removing ...

IMO it is an effective ion drive.

The first thing that needs to be done is to invent a fusion reactor. The second thing would be to then invent a fusion reactor that is small enough...
