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

   "Dean Lynn, 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." Lynn explained.

  Orlando's expression became serious. Although the news of the war was only circulated within the parliament, many wizards had guessed a clue through the recent major actions of the parliament.

   "By the way, I also plan to continue to expand Iyeta Academy, and recall those wizard apprentices who have left the school, and even official wizards, to Iyeta so that they can continue to study." Lynn proposed again.

  Orlando was 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, but they couldn't be promoted due to lack of talent.

   Not to mention graduate students, they are also formal wizards, and they can't teach even if they want to.

   "Of course it is teaching chemistry, physics, and Mathematical Olympiad!" Lynn said firmly.

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

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

  Lin En explained briefly, and finally asked Orlando to compile a list of alchemists, especially those wizards who had done some research on steam engines, and invite them all to the academy!

  …

   At noon on the second day, in the alchemy research room of Iyeta Academy.

More than 20 wizards turned around and looked at a few large white papers. A very strange machine was drawn on it. Attracted everyone's attention.

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

   "Dean Lin En, what is this?" An alchemist looked at Lin En in confusion, and then suddenly seemed to remember it, and said in surprise. "Could it be the blueprint of the alchemy steam engine?"

  Hearing this guess, all the wizards present were cheered up.

  The alchemy steam engine is the highest achievement of the Alchemy Association, and it is claimed to be a magical invention capable of changing the world!

   They are naturally very interested in this thing. Some people even dismantled the alchemy equipment placed on the ship and secretly researched it. Over the years, they have produced some results.

  However, the structure of the alchemy steam engine does not seem to be like this. They even wondered if the dean took the wrong blueprint.

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

Upgraded version? Philip and the others looked at each other.

   "Is there any difference between it and a steam engine?" Another witch asked curiously.

   "Its efficiency is more than ten times that of the existing steam engine!" Lynn replied affirmatively.

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

  The steamship powered by this is not much faster than the sailing warship when sailing on the sea, and the cruising speed of the airship can only be maintained at a poor 15 kilometers per hour.

   Of course, this does not prevent the steam engine from being a cross-age invention.

   "How much? Ten times?" All the alchemists gasped, looked at Lin En with a monster-looking gaze, and then looked at the blueprint in front of them, their eyes became much more eager.

   "Can it be placed on the airship?" Lydia asked excitedly.

   "Of course no problem, it can increase the speed of the airship from 15 kilometers per hour to more than 70 kilometers per hour!" Lynn said a value that was as conservative as possible. "It can also be used to drive ships or anything you want it to move!"

   "Seventy kilometers? Wouldn't it take half a day to get from Iyeta to Greenriel?" Philip said in amazement.

   This is too fast too.

   Is it really that fast?

  Lin En smiled, then took the blueprint, and explained the working principles of steam and internal combustion engines and their differences to a group of alchemists and half-ling craftsmen like Darren.

  A steam engine essentially boils water, turning the water in the boiler into steam, which is then sent to the cylinder to push the piston to reciprocate.

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

  Internal combustion engine, as its upgraded version, reduces steps, converts heat energy into mechanical energy, and generates high-temperature and high-pressure airflow through the rapid combustion of fuel to drive the piston, so the efficiency will naturally be much higher.

   As for its fuel issue.

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

   Coal resources are still available in the Wizard's Land.

  In fact, Lynn prefers to directly use hydrogen as fuel, so that not only the thermal efficiency can be increased to more than 50%, but it is also 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, compared with the cost-effective use of fossil fuels.

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

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

It's just that the almost zero industrial level of Iyeta Harbor has caused Lin En a headache. He can only hope that these alchemists can find a way to use magic to solve various technical problems and create an alchemist that combines technology and magic. internal combustion engine!

  Even though Lynn explained the principle of the internal combustion engine in great detail, the large number of nouns included in the middle still made the alchemists think about it for a long time. After a while of disputes and discussions, they started the transformation process.

  For example, improving the cylinder’s ability to withstand high temperature and high pressure, or how to burn the alchemy formation into the internal combustion engine, so as to continuously produce combustible gas without being damaged by the internal high temperature environment...

  Lydia and the others did not participate in the research on magic modification, but were very interested in something called a gear in the 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, it is far from so delicate...
