Chapter 203 This thing is called a magic internal combustion engine! [Added update for leader dsf23dd]

"Dean Linn, can you tell me what these things are used for?" Orlando asked curiously.

"Make several weapons to deal with a war that may be coming." Lin En explained.

Orlando's expression became solemn. Although the news of the war had only circulated within the Parliament, many wizards had already guessed some clues from the recent major actions of the Parliament.

"By the way, I also plan to continue to expand Iyeta Academy, and recall those wizard apprentices and even formal wizards who have left the school to Iyeta so that they can continue their studies." Lin En proposed again.

Orlando was completely shocked, and it took him a long time to react, "But, what should we teach?"

The wizard apprentices who were expelled from the academy were all over thirty years old and had basically learned everything they could teach. They were just unable to be promoted due to lack of talent.

Not to mention graduate students, they are all official wizards, so they can't teach them even if they want to.

"Of course we teach chemistry, physics, and Mathematical Olympiad!" Lin En said decisively.

"Chemistry? Physics?" Orlando paused. He knew the Olympiad, but what were these two subjects?

"You can also understand these two new subjects as the principles of magic, or the laws of how things work!"

Linn gave a simple explanation, and finally asked Orlando to compile a list of alchemists, especially those wizards who have done some research on steam engines, and invite them all to the academy!

…

At noon the next day, in the alchemy laboratory of Ieta Academy.

More than 20 wizards gathered around several large white papers and looked over them. On them was a very strange machine. The components were very complex and difficult to understand, but the exquisite structure was immediately revealed.

Attracted everyone's attention.

Darren and others were also invited, but they were squeezed outside and did not dare to compete with the wizards for the drawings. Only Lydia moved a high chair without any scruples and even wanted to climb on it.

Get to the table and watch.

"Dean Lin En, what is this?" An alchemist looked at Lin En in confusion, and then suddenly said in surprise as if he remembered it. "Could it be the blueprint of an alchemy steam engine?"

Upon hearing this speculation, all the wizards present were shocked.

The Alchemy Steam Engine is the highest achievement of the Alchemy Association, and it is said to be a magical invention that can change the world!

Naturally, they were very interested in this stuff. Some even dismantled the alchemy instruments placed on the ship and studied it secretly. They have also produced some results over the years.

However, the structure of the alchemy steam engine didn't seem to be like this, and they even suspected that the dean had gotten the wrong drawing.

"No, to be precise, it is an upgraded version of the steam engine. I call it an internal combustion engine!" Linn explained with a smile.

Upgraded version? Philip and others looked at each other.

"What's the difference between it and a steam engine?" Another witch asked curiously.

"Its efficiency is more than ten times that of existing steam engines!" Linn replied affirmatively.

He has already checked the steam engine built by the Alchemy Association. The thermal efficiency is between 3% and 5%, which can only be described as very inefficient.

A steamship powered by this is not much faster than a sail warship when sailing on the sea, and the cruising speed of the airship can only be maintained at a pitiful fifteen kilometers per hour.

Of course, this does not prevent the steam engine from being an invention that spans the ages.

"How many? Ten times?" All the alchemists took a breath and looked at Lin En with a look that looked at a monster, and then looked at the blueprint in front of them, their eyes became much more eager.

"Can it be put on an airship?" Lydia asked extremely excitedly.

"Of course, no problem. It can increase the speed of the airship from fifteen kilometers per hour to more than seventy kilometers per hour!" Linn said the value as conservative as possible. "It can also be used to drive ships or whatever you want.

It moves things!”

"Seventy kilometers? Doesn't it take more than half a day to get from Ieta to Greenriel?" Philip said in surprise.

This is too fast.

Is it really that fast?

Lin En smiled, then took the drawings and explained to the alchemists and halfling craftsmen such as Darren the operating principles of steam and internal combustion engines and their differences.

The essence of a steam engine is to boil water, convert the water in the boiler into steam, and then send it to the cylinder to push the piston to reciprocate.

Simply put, it converts the chemical energy of fuel into thermal energy of steam, and then converts the thermal energy of steam into mechanical energy, thus generating a steady stream of power.

As an upgraded version of it, the internal combustion engine reduces the number of steps, converts thermal energy into mechanical energy, and generates high-temperature and high-pressure airflow through the rapid combustion of fuel to drive the piston movement, so the efficiency is naturally much higher.

As for its fuel problem.

The most primitive internal combustion engine used gas as fuel to provide energy.

There are still coal resources in the Wizarding Land.

In fact, Lin En hopes to directly use hydrogen as fuel, which will not only increase the thermal efficiency to more than 50%, but will also be very environmentally friendly and pollution-free.

This idea was proposed as early as the 18th and 19th centuries, but the extraction, storage and transportation costs of hydrogen fuel are very high. In comparison, it is more cost-effective to use fossil fuels.

However, for wizards, the production of hydrogen is not that difficult, which makes hydrogen-powered internal combustion engines possible.

In this way, it is possible for the airship to reach a speed of 200 kilometers per hour, let alone 70 kilometers per hour!

It's just that the industrial level of Iyeta Port is almost zero, which gives Linn a headache. He can only hope that these alchemists can find ways to use magic to solve various technical problems and create an alchemy machine that combines technology and magic.

internal combustion engine!

Even though Linn explained the principles of the internal combustion engine in great detail, the large number of terms mixed in between them still made the alchemists ponder for a long time. After a period of argument and discussion, they began the transformation process.

For example, improving the cylinder's ability to withstand high temperatures and pressures, or how to burn alchemical formations into internal combustion engines to continuously produce flammable gas without being destroyed by the high temperature environment inside...

Lydia and others did not participate in the research on magic modification. Instead, they were very interested in something called a gear in an internal combustion engine.

Several gears of different sizes fit together and transmit power through rotation. It is very magical. Although she has seen similar things on steam machines before, they are far from so exquisite...
