No. Tritium is not part of the initial sequence. That's just 1H + 1H
It started with hydrogen (actually H3)
And contrary to belief, the sun does not fuse hydrogen!
Deuterium (hydrogen-2) and a proton (hydrogen-1) fuse, producing helium-3 and energy,
Ognjen Ilic, postdoctoral scholar and the study's first author, gives an analogy: "One can levitate a ping pong ball using a steady stream of air from a hair dryer. But it wouldn't work if the ping pong ball were too big, or if it were too far away from the hair dryer, and so on."
With this new research, objects of many different shapes and sizes—from micrometers to meters—could be manipulated with a light beam. The key is to create specific nanoscale patterns on an object's surface. This patterning interacts with light in such a way that the object can right itself when perturbed, creating a restoring torque to keep it in the light beam. Thus, rather than requiring highly focused laser beams, the objects' patterning is designed to "encode" their own stability. The light source can also be millions of miles away.
"We have come up with a method that could levitate macroscopic objects," says Atwater, who is also the director of the Joint Center for Artificial Photosynthesis. "There is an audaciously interesting application to use this technique as a means for propulsion of a new generation of spacecraft. We're a long way from actually doing that, but we are in the process of testing out the principles."

Yes to eclipse and yes to Luna being in the right place/time-frame for a close fit, but what about the 99.9999% of the time when the Moon is not at the right place for a eclipsing shield or the areas of Earth not in shadow? Pee poor planning!
The arguments for the moon being somewhat artificial aren't completely loony, tho.
If the fourth state of matter is plasma where the bonds holding atomic partcles together are no longer present, one can disassemble and reassemble any elements you desire.
However, if one can weaken the bonds that hold electrons to the nucleus, take that a step further and weaken the bonds that hold the neucleus together.
That is not how plasma is created. The bond is not weakened, the electrons are torn away.
Sure, if one were able to manipulate the strong nuclear force one could do lots of cool things, I guess. But it has nothing to do with plasma.
While you're at it, could you do something about gravity and inertia? They're sort of pesky.
A star is a fusion reactor, fusion resulting from very high temperatures and pressures. Thanks to gravity.
It is a thing. It's a cloud of ions and electrons. Like a puddle of water is a thing, a bunch of water in a liquid state.
But your thinking in terms of plasma being a "thing" and not a "state".
Pretty much. Though there is probably some helium fusion going on now, as the Sun gets older and its hydrogen gets used up, that reaction will predominate.
Only the fusion of hydrogen? Nothing more?
How do you ignite a star phage? Just squish it together untill it ignites?
No. But as I said, it does have a lot of gravity. Whole lot of squeezing.
But does a star gave a cylinder and sleeve around it in astrophysics?
