The resurgence of old love between old lovers is just an interlude after all, and how to survive is the theme of the current doomsday.
For Chen Xin, he no longer has to worry about how to survive.
The emergence of hot spring water has greatly increased the heat energy that the ground source heat pump can obtain. Even if Chen Xin turns off the equipment, the temperature in the shelter can be maintained at about 13 to 16 degrees Celsius due to the influence of the rising groundwater temperature.
If it were not necessary to maintain the temperature of the greenhouse, the ground source heat pump that Chen Xincai had just made would even be somewhat redundant.
But this also gave him a new idea, which was to use the heat generated by ground source heat pumps to generate electricity that he had thought about before.
This is technically not difficult to achieve. You only need to connect a heat recovery device to the heat pipe, and then use the heat to convert thermal energy into electrical energy.
As for the means of converting thermal energy into electrical energy, the steam turbine commonly used in thermal power plants is enough to complete the task.
Speaking of steam turbines, Chen Xin was particularly obsessed with geeks for a while when he was in college. In his dormitory, he used an air mattress blower and discarded CDs to transform a Tesla turbine that could actually power a light bulb.
Although this thing has no practical significance at all and relies entirely on the blower to drive the impeller to rotate for work, overall, the thing has been made, and it is not complicated to make it. Now in Chen Xin's computer There are also drawings he used at that time.
The Tesla turbine is a turbine invented by Nikola Tesla, the legendary physicist of the Federation.
This turbine is much more efficient than traditional blade turbines, and Nikola Tesla once dreamed of using it to generate electricity from geothermal energy.
Of course, although this technology looks very beautiful, its practical application is still restricted by many conditions, so that it has been more than a hundred years since this technology was invented by Nikola Tesla, and there are still few practical applications.
The main reason that restricts the promotion and application of this technology is that the internal rotor must be made of discs that are thin enough and have a smooth enough surface and are arranged in a close enough manner to form a large enough rotor, so that the rotor can move the fluid passing through the rotor. Under the action of boundary layer effect, the rotor is driven to rotate at high speed.
This undoubtedly places extremely high requirements on the materials used to make the discs, which must be both thin and strong.
And a big problem with bladeless turbines is that the greater the load, the lower the efficiency, and in order to achieve a sufficiently high speed, the fluid flow through the rotor must be as small as possible.
But this is not a problem for Chen Xin.
With the help of the system, the production of the rotor is not a problem at all, and all Chen Xin needs is a small generator that can meet the power needs of his shelter. Neither the load nor the fluid flow is too large.

"A Xin, what are you doing?" Qin Lan couldn't help but feel very curious as she watched Chen Xin continuously process a piece of metal material into a thin circular metal piece on the workbench.
"Make a turbine. I plan to use the excess heat from the ground source heat pump to generate electricity, which requires a turbine." After hearing Qin Lan's inquiry, Chen Xin explained to her without stopping his work.
Chen Xin is actually not processing these round metal sheets by himself, but in Qin Lan's eyes, Chen Xin is processing them by himself.
With the help of the system, the metal materials are processed into thin paper-like metal discs and assembled, and then the main shaft is installed in the middle. The rotor of the bladeless turbine is ready.
Qin Lan watched Chen Xin working seriously and did not disturb him. She just leaned next to Chen Xin's workbench and watched him work quietly.
There is a saying that men who work hard are the most handsome. The look Qin Lan looked at Chen Xin undoubtedly confirmed this statement.
But Chen Xin didn’t notice the fascination in Qin Lan’s eyes as he looked at him. He just put the assembled rotor into the volute.
After assembling the entire turbine casing and checking that there was no problem, Chen Xin turned the rotor by hand and confirmed that the rotor was operating normally by manual turning, and then connected the entire volute to the gear box.
Although the speed of the bladeless turbine is high, the torque is not large. If you want to obtain sufficient output power, it is necessary to use a gearbox to reduce the speed and increase the torque of the drive shaft.
This is not a complicated process, a set of planetary gears can solve the problem.
As for the generator part, it is even simpler. Even junior high school students understand the principle of cutting magnetic field lines to generate electricity.After all the parts are assembled and a generator connected to the bladeless turbine is completed, the next step is to install it.
"Alan, help me carry it over." The finished generator was a bit heavy, so Chen Xin had to ask Qin Lan to help.
The two of them carried the generator to the ground source heat pump and put it down. Qin Lan asked curiously: "Where will this be installed?"
"Just connect the pipe to the condenser. When the air flow in the pipe passes through the condenser, it can absorb the heat emitted by the condenser, thereby expanding the volume of the air and forming a high-speed air flow to drive the rotor of the turbine to rotate." Chen Xin After explaining, he opened the system interface and chose to consume survival points to install the equipment.
System installation is much more convenient and faster than Chen Xin’s manual installation. They even helped him lay out the wiring and connected the generator to the power distribution room.
As Chen Xin adjusted the output power of the ground source heat pump and turned on the turbine switch, the generator also started running.
"It actually started to move!" Seeing that the turbine and generator connected to the condenser by Chen Xin started to move, Qin Lan couldn't help but exclaimed: "Axin, you are so awesome!"
"Anyone who knows something about mechanical processing and physics can make this. It's nothing special." Chen Xin shook his head and didn't feel proud of Qin Lan's praise: "If it weren't for the hot springs underground that caused the ground temperature to rise, this set of The power generated by the system is enough to maintain the operation of the ground source heat pump equipment.
But now that the ground temperature is rising, the excess heat energy can be converted into more electrical energy. As long as the power of the generator is larger, it should be able to maintain my electricity consumption here.
“I am only worried that the increase in groundwater temperature is temporary. When the broken groundwater layer is blocked again and the low temperature drops"
Speaking of this, Chen Xin couldn't help but show a worried expression.
"A Xin, you are too pessimistic. Think better, maybe this is permanent? You will have hot spring baths in the future." Qin Lan laughed and encouraged Chen Xin with a smile, hoping that he would be more optimistic. (Remember the website address: www.hlnovel.com - Didn't finish reading?
