I have built a thermonuclear fusion reactor that creates helium from hydrogen
It also captures the power given off during the reaction as electrical power.
Below are some photographs.

Two Reactors on Shelf with telephone.

Before: - Glow colour pink (hydrogen)

After: - Glow colour Green (helium)
Images shows reactor chamber before and after reaction.
The "before" image shows the red glow of hydrogen the "after" image shows the green glow of helium.

The protons are "hot" enough for the higher energy process of 4P>He to take place.
The criticism is that sodium vapour from the glass got into
the tube making it yellow. However the diagnostic green line of helium is
visible so helium is present in the tube.
I accept the criticism.
I am now getting some success and I invite others to try out the reactor and test it to see if it does in fact work.
