Two years passed quickly, space construction was speeding up, and a large number of Carters boarded transport ships and traveled thousands of miles from Sori to the asteroid belt.

Myron, who was directing the deployment of resources, suddenly received a message from a construction ship manager.

"Mr. Myron, the current construction plan is going very well, a total of one million large engineering ships have been completed, when will our first space battleship be built?"

"Some key factors haven't been worked out yet, wait a while."

"Mr. Myron, we are short on time, Amoeba only gave us dozens of revolutions, if we don't start building battleships now, I'm afraid it will be too late then."

The captain of the engineering ship affirmed his anxiety, and this was not just him, he was just a representative, representing all the Carters of the entire engineering ship, and the other million engineering ships, who had been waiting for Myron's order to watch the time pass gradually, but they could not help but feel anxious when they had not received the construction task.

"Then you will design and manufacture the battleship keel first, remember, it can only be the keel, don't think about it superfluously, then it will be time-consuming to modify the battleship that has been finalized."

Myron emphasized that he could only start the design and layout of the battleship's keel, and the captain of the engineering ship was a little unclear.

"When is the time?"

"The technical team led by Dopps is intensively developing a nuclear pulse engine and a new weapon that can be used in space warfare." Myron explained.

The captain of the engineering ship almost thought that he had heard it wrong, but he also realized that Myron's intention to wait, relying on chemical propulsion to fight a space war is looking for death, and Bichong will be the death hole of a chemical propulsion warship, so a nuclear propulsion engine is needed.

The good psychological quality made the captain of the engineering ship quickly accept the reality and ask.

"How long do we have to wait?"

Myron shook her head, "It won't take long, soon." ”

At this time, on Sori's side, in a certain scientific research institute, a bunch of scientists were arguing, and the tables and papers in the entire conference room were all over the floor, with all kinds of messy formulas written on them, and there were also various formulas on the walls and doors.

The air in the room was very turbid, and these people had never left the room except for excretion, as evidenced by the lunch boxes that were piled up in one corner of the room.

Everyone couldn't hide their exhaustion, but their eyes were still so bright.

"Again, we need to use nuclear energy as the propulsion power of warships, and rely on chemical propulsion to fight a space battle, which is looking for death!"

"But what do we do? As mentioned last time, relying on the continuous blasting of small nuclear bombs as a driving force has proven unfeasible, the utilization rate of nuclear energy is very low, most of the explosive energy of nuclear bombs is not projected onto the hull and converted into power, and at the same time there is a large amount of waste heat that will accumulate on the buffer plate, and there is no material that can withstand such high temperatures without cooling down continuous blasting propulsion. ”

"Then we can inject nuclear energy into other substances in another way, and use other materials to efficiently convert nuclear energy into kinetic energy."

"How do you bet?"

"We can try to use nuclear energy to warm the matter to the plasma state, then use an electric field to confine the plasma, and finally rely on the electric field to emit the ions in the plasma, so that after calculation, assuming a payload mass of 4,000 tons, the speed of the spacecraft can be increased to one-eighth of the speed of light."

All of them were focused on him because of the idea of this member of the Academy.

At this time, some people asked.

"But what about the temperature? The temperature of the plasma is bound to be extremely high, which would require a large amount of cooling agent. ”

"There is no need for a large amount of cooling agent, the vacuum environment of the universe itself is a natural insulating layer, and if the plasma wants to transfer heat energy to the inner wall of the reaction chamber, it needs to have material contact with the inner wall, but in the state of strong electric field control, this is not possible." The proposer of that plan explained.

But skeptics still find it inappropriate.

"However, the external ions will still bring the heat out, and there is still heat accumulation on the inner wall, although the temperature will not rise quickly, but that does not mean that there is none."

"That's right, so I don't deny that there is still a need for coolers, I think only a small amount is enough, and we can discuss the issue of cooling separately, and the top priority is to solve the nuclear energy space engine."

The decision of the plan was handed over to Dopps, who was highly respected in the scientific community of the Carter civilization and was selected as the commander-in-chief at the same time.

Dopps pondered for a moment and then spoke slowly, "Very interesting plan, but the problem is ...... Can I help you? ”

Before he could finish speaking, someone rushed in from outside the room, panting against the door, holding a stack of paper in his hand, looking tired, but his eyes did not look tired at all, only excited.

"Whew... Whew, blow up, blow up! The man shouted excitedly.

"What blew up?"

The other academic members in the room looked at the excited man at the door in a strange way.

"Hydrogen bomb! Mr. Dopps, your nuclear fusion theory has been confirmed! ”

The man quickly walked up to Dopps and handed out the stack of papers in his hand, and Dopps, who took the paper, scanned the data on the paper with a serious face, and at the same time took a disk sandwiched in it from the paper.

Fortunately, there was a projector in the room, and the image from the disk was projected, and from the slightly curved horizon, an extremely strong and dazzling light was released, followed by a huge shock wave, and a mushroom cloud, the power of which was recognized by the members of the academic community as an atomic bomb.

It was a hydrogen bomb, and this hydrogen bomb represented more than just great power, which means that nuclear fusion is a viable theory!

There was silence in the room for a while, and Dopps broke the silence.

"What about the yield of deuterium?"

"The deuterium reserves in the Sori Ocean are extremely rich, accounting for one-eighth of the total ocean mass, and a large amount of deuterium can be produced by simple centrifugation." The person who came to report answered truthfully.

"I see, thank you for your hard work."

After the debriefing departed, the members of the academic who had just proposed the use of ions as a medium of propulsion spoke.

"Mr. Dopps, may I ask the question you just said......"

Dopps stopped the other man's words, and he smiled, and anyone could see how happy he was at the moment.

"No, it's not a problem anymore, just now, the problem I wanted to say has been solved."

"Ladies and gentlemen, nuclear fission is not suitable as the main energy source of nuclear energy engines, and due to the scarcity of reactants and the harsh conditions for energy release, I decided to add nuclear fusion to the design." Dopps solemnly announced.
