Liu Zheng's eyes lit up and he continued to read down. It read: 'We have recently discovered that there is a connection between electricity and magnets. Electricity can be attracted by magnets.'
'And electricity has the same gravitational force as magnets, but electricity can attract paper to float. Based on this phenomenon, we have created a device that can be used to transmit information.'
'We call it a transmitter.'
'However, electricity cannot be stored for a long time, so we use rubbing wool to generate electricity to run the transmitter, but this is too stupid.'
'We have looked for several things that can store electricity. One is to add water to a glass bottle, connect it with copper, and seal the mouth of the bottle with a rubber stopper, which allows us to capture the electricity.'
Seeing this, Liu Zheng showed a satisfied smile. The prototype of the telegraph machine had been developed.
The key to the problem now is to develop a capacitor so that the electrical device can truly operate. He thought of the knowledge he learned in his previous life.
Now there are basic prototypes of capacitors, but such capacitors cannot achieve the required effects.
After thinking of this, Liu Zheng used the knowledge from his previous life to write a reply.
'Oil is more conductive than water. You can try it with an oil barrel. In addition, magnets are related to electricity. As far as I know, cutting copper between two magnets can generate energy.'
'If the magnetic force is strong enough, the energy generated will be greater, you can give it a try.'
‘…’
After writing the reply, Liu Zheng began to think about his next plan. The invention and creation of electricity were very difficult, and Liu Zheng did not have such a deep understanding of this aspect.
But he knew that electric energy must be generated, discharged, and used at the same time. These three steps must be carried out at the same time.
However, the current level of scientific research cannot reach this step, and there is currently no power plant.
Liu Zheng sighed. If the capacitor is successfully invented, the construction of power plants will be much faster.
By that time, the establishment of power transmission in Longyan will make Longyan's industrial level a century ahead.
Engines and generators and telegraph machines.
These inventions will be crucial in the future.
Liu Zheng handed the letter to the boy and delivered it. He sighed in his heart, Long Yan still needs more talents.
The research and development progress of Liangzhou Laboratory has been somewhat slow.
The next step is to speed up the search and recruitment of talents.
However, this matter cannot be rushed.
This matter requires long-term planning. According to Liu Zheng's prediction, Europe will definitely enter a turbulent era in the future, with Prussia and Austria now competing for the throne.
The battle between Britain and France for maritime supremacy.
It looks like a very huge war, but there are very few countries that are actually attacked and have unstable domestic situations.
However, the coming years for Europe will surely be turbulent.
Liu Zheng knew from the history he had learned in his previous life that now that the industrial revolution had arisen, human research on natural sciences would impact so-called religiosity.
In addition, since the industrial revolution, those businessmen have amassed a lot of wealth.
However, a relatively complete order has not been established, which will lead to the outbreak of a series of unrest.
According to the information Liu Zheng received, the current domestic situation in France is not that good. Religion, imperial power, and capitalists are squeezing the blood of the people at the bottom.
Liu Zheng didn't know whether the history of this world would repeat itself like the previous one, but Europe would definitely be in turmoil.
Long Yan must attract talents, so it must relax its policies.
