Helium3 fuel from lunar regolith.
It only requires 4% of the temperature of the H-H fusion reaction. This makes the first containment wall feasible with today's materials.
Every square kilometer of lunar regolith contains enough energy to run NYC for a year.
The moon is the Saudi Oil Fields of the 2030s.

If the plasma touches any material, it will pollute the plasma, and shutdown the process(often disastrously). There are no materials that can contain the plasma. That is why a magnetic field is used to contain the plasma. We started doing this in the 1950's but there was a problem, the magnetic field would be in the shape of a tube, and what do you do with the ends? The Soviets solved this by connecting the two ends to make a donut shape that they called a tokamak. They invented it, so they got to name it, and we all call it a tokamak now.
This has allowed us to contain plasmas hotter than the inside of the sun. There is no problem containing hot plasmas. It takes more energy to get things super hot, but no problem containing them.
Kurmugeon has a 15 minute education that really is showing its lack of education.
Just stating the obvious, 5% of the rocket is reusable. 95% is fuel, and by definition not reusable. When you think of it like that, it is not a huge saving to reuse only 5% of the rocket. In fact, there is a danger that if you need more fuel to land the rocket, you might waste more than you reuse.

Think about it: if you have to waste 10% more of the rocket to reuse 5% of the rocket, you are making a loss.

You made the assertion. Not I.
Yes, the assertion that paying 10% more to save 5% is a loss of money.
