After singing songs and drinking herbal liquor for a time, Einar gave the order to lift the fishing net.

So the sailors lifted the fishing net using levers, because of the size of the catch the net was too heavy.

So it took a while to upload it, when they did it all were surprised by the enormous amount of fish that was there.

Einar walked to the net and three huge cod, which weighed about 20 kilograms each.

"These cod must be cooked, let go of the catch before the fish end up dying and we pollute the sea with corpses."

The sailors released the nets and all the fish fell back into the sea where they swam to other places to escape from that place.

Lars was surprised when he saw the huge cod "Konungar Einar, is it okay to let go of such valuable fish, shouldn\'t we keep them?"

Einar shook his head "It is just a sample of how trawling will be done. We will catch another full fishing net, but we will let it go.

In this way, we can imitate the stress conditions of the fishing net and the pulley system.

We will already catch the third fishing net tomorrow before returning to the tribe, but for now help me clean these cod, I will prepare them onions. "

Lars took the three codfish and started cleaning them by gutting them and removing most of the bones inside.

When he finished, he cut them into pieces and placed them on a glass plate. Meanwhile, Einar was using the solar stove to heat oil in a frying pan.

When the oil was hot, he placed four onions cut into cubes and six garlic, which he allowed to cook in the oil.

Later, he put the cod fillets on the oil and at that moment put oregano, salt and ground pepper on the cod fillets that were being cooked.

The aroma of freshly prepared food put the sailors in a good mood who waited for Einar to finish cooking.

When Einar finished cooking, he put a good quantity of fish in glass dishes so that all the crew could enjoy a full meal.

That way, they would have the energy to work the rest of the day.

The sailors, when tasting the food, thanked Konungar Einar for such delicious food. Even Lars never thought that cod could be so tasty.

"If the merchants can bring olives in December, I will prepare a delicious cod for the Yule festival.

It is a recipe from Valhalla itself, which will use exotic ingredients such as tomato, but you will have to wait until the Yule festival.

Anyway, there are still more cod onions who want another portion? "

The sailors lifted their plates and lined up to receive another ration of food.

After this, they all took a two-hour break, where they drank herbal liquor. At the end of the rest period Einar ordered the nets to be lowered again.

This time, however, he noticed that the pulley system was being forced, so he ordered everything to stop.

"It seems to be the weakest part of the link. I think that instead of using bronze, the steel should be used."

Einar then checked the network and found that it had some small gaps, which would not affect the performance of the network.

\'Perhaps it can only be used efficiently only three or four times before the damage is so advanced that it is useless to use it.

 

Although for the amount of fish got, it is worth the expense of making new fishing nets, I will have to create workshops with slaves in the port. \'

Einar sighed and looked at the sailors "I want you to take the spare parts for the pulleys and a screwdriver from the warehouse.

Do not take too long because I have to analyze if the damage to these pulleys can be reduced with a new material or it is necessary to add more pulleys to redistribute the weight. "

The sailors ran towards the warehouse from where they took the things that Einar had asked them, when they were given to him.

Einar began to disassemble the pulleys and saw that the metal had deformed because of the weight, so he stroked his mustache.

After seeing each of the deformed pulleys, he turned his head and looked at the wooden base.

\'In theory, if I distributed the weight between three other pairs of pulleys, the bronze should be able to withstand the weight.

 

If the mechanical advantage is defined by the quotient between the load and the effort.

 

The speed advantage is the ratio between the speed reached by the load and the speed of the point of application of the effort.

 

Finally, the efficiency is defined by the quotient between the useful work produced and the work supplied.

 

If I applied the formula correctly, the pulley system should work with four pairs of pulleys to redistribute a weight of tons. \'

Einar wiped the sweat from his forehead and asked the sailors to help him install the new pulleys. The sailors did not hesitate to help his king, so in just a few hours, they installed the new pulleys.

After this, Einar arranged the rope on the pulleys and asked them to lower the fishing net.

In doing so, Einar took a notebook and a charcoal pencil while he wrote some accounts on the notebook to check whether his opera was correct.

He may not be a man who knows everything, but at least in mathematics he was extremely precise because he always liked them as well as history.

When he finished doing two math fact sheets, he drank some herbal liqueur and waited patiently for the net to catch all the fish.

While he waited, he thought about unique plans he had to improve the island, from auxiliary roads such as sea routes to have complete control of the island.

\'Now that I have copper and I have magnetite, I should try to make a hand crank generator. If I can do it, I should be able to produce enough power to light a little horn.

 

But how to make a horn if I don\'t know how to transform electrical energy into sound energy. \'

 

Einar frowned, as that was a big problem, since all he knew about the speakers was that the sound was a wave.

So in theory, to create sound, it had to create vibrations, which had to be amplified, but that presented another problem that it could not solve.

After looking for many options, he ends up giving up trying to think of a solution.

\'I have to talk to artisans but, first I have to design a crank electric coil, although it will be useless...\'

 

Einar then thought that if he could create a group of crank coils and connect them to the barbed wire, he might have electrified wire.

The voltage may be too small to kill a person, but it will prevent you from being touched voluntarily.

\'I could put a coal-fired Stirling engine on the watchtowers that can be turned on to provide power to run the hand-cranked generators.

 

That way, in the event of an attack, the Stirling engine will turn on and the barbed wire could be electrified. It would not be deadly, but it would save us time.

 

Valuable minutes can be the difference between life and death, also in this time of little science and many beliefs.

 

It will be of even higher value if it is said to be a blessing from the thunder god Thor. \'

A smile formed on Einar\'s face, as he already knew which project to work on in his spare time.

After this, he gave the order to lift the fishing net, which took a little longer to go up, but now the pulleys were not damaged.

When it was fully up, Einar looked at the fish load and did an analysis on the approximate weight, so he let the animals be released.

After this, everyone took advantage of the last hours of the sun to talk and went to sleep to get up at dawn.

During the early morning, Einar got up from his bed and stretched out his hands, although he had slept well.

He was not too comfortable because he did not have his wives by his side.

\'It is much better to wake up and see their beautiful faces, than to see an empty bed.

 

I guess I\'ll have to work harder to increase the family.\'

After this, he exercised and woke up sailors because they had to catch the fish that they would take to the port.

All the sailors worked with all their strength and after some time they had everything ready, so they lowered the fishing net.

At the end they only waited for Einar to give them a signal. When Einar thought it appropriate that they would lift the fishing net, he did so taking tons of fish with it.

Which this time was placed on the warehouse that had been prepared to store the fish, moving the net with the help of the pulleys.

The contents were emptied into the warehouse and, although some fish could escape, most remained inside the warehouse.

"Let\'s start the journey home because it won\'t take long for the fish to start to rot and the sun can make that process faster."

All the sailors raised their sails, and they all set out on their way home, following Einar\'s compass.

So in just two hours, they could see the coast of Iceland. After getting closer, they could see the beautiful walls of the port.

Which were built with cement and partitions, so they had a spectacular view.
