To solve the problem of electricity consumption, either the biomass produced by Chen Xin is used to generate biogas power to meet its own consumption, or Chen Xin continues to upgrade the current shelter's power system, hoping to upgrade it into a power system with stronger self-sustaining capabilities, such as a nuclear reactor that can operate for decades.

The first option is naturally impossible because energy conservation.

If the biomass produced by the oxygen generator is used for biogas power generation, it can satisfy the system's own consumption, wouldn't it mean that this is a perpetual motion machine?

Therefore, the solution to the problem is to continue to upgrade the system, and upgrade to energy conservation and updates.

But Chen Xin has checked his generator and power system. Among the system upgrade options, there are only two upgrade options: improving the generator's working efficiency and improving the energy saving rate of the entire power system. It is not possible to upgrade it to other types of generators for the time being.

But this is not absolute. Chen Xin thought of the tactical raincoat when he upgraded his protective suits before, so that the protective suits could add the functions of the raincoat and the surface tactical camouflage. He felt that if he could provide other power generation methods, he could also be integrated into the power system.

"If I integrate biogas power generation into the power system, use gasoline generators as the main power and biogas power generation as the auxiliary, and supply power at the same time..." Thinking of the ability to integrate other power generation methods into the power system, Chen Xin hurriedly took out a paper and pen to calculate.,

"Now the consumption of planting greenhouses requires the generator to consume 20 liters of gasoline per day to maintain it, and the consumption remains unchanged..."

"The planting greenhouse can satisfy my own oxygen consumption when there is light, and there is still surplus output... but considering the overflow of the ventilation system and the oxygen consumption after turning off the light..."

"When the light time remains unchanged for 12 hours, the oxygen produced by planting greenhouses can maintain my consumption for 16 hours without considering the presence of external oxygen..."

"Extending the light time to increase oxygen output can provide the oxygen I need for 24 hours, but at least more than five hours of light per day will increase gasoline consumption from 20 liters/day to 30 liters/day..."

"If you build an algae cyclic oxygen generator, the electricity consumption is smaller than the long-term light of the planting greenhouse. In addition, the electricity supplement brought by biogas power generation, you only need to increase the gasoline consumption by another 5 liters per day..."

List all the data for calculation, and Chen Xin easily calculated the results.

Looking at the results he calculated, Chen Xin touched his chin and obviously constructed an algae circulating oxygen generator he told Mo Qingyan, which is the least consumed solution at present.

Moreover, when Chen Xin built such an oxygen generator, he could upgrade the oxygen generator through the system to improve its oxygen generator efficiency, biomass output, biogas reaction efficiency... and even transform biogas power generation into biomass fuel cells or convert the produced biomass into edible algae.

Thinking of this, Chen Xin sincerely thanked that he picked up this system when he entered the shelter, instead of turning a blind eye to it as an ordinary meteorite.

—————————————————

Since he decided to build an oxygen generator, Chen Xin obviously had to take a look at the resources he had.

After all, this is not like upgrading an existing item. He can directly upgrade with the help of the system's survival points.

This is also the biggest shortcoming of this system. It cannot create something out of thin air and can only upgrade based on what is already available.

Even if the items used as the basis for upgrading are simple and original, as long as there is a material foundation, the system can continuously improve them.

But without this foundation, everything is not discussed.

So even if Chen Xin built a sink with a wooden board to allow algae to grow in the water, and then insisted that this was an oxygen generator, he had to build the sink first.

Fortunately, Chen Xinshou did not lack supplies, so he didn't have to build a sink with wooden boards so primitively.

To build an algae circulating oxygen generator, the first thing you need is not a sink, but a foundation for algae to grow and depend on, that is, the biological facade.

This is not complicated. If it is not so particular, the screens used at home can be used just as much as possible.

Let the algae adhere to it, then provide water, carbon dioxide and light, and soon the algae will start to grow and reproduce and perform photosynthesis to release oxygen.

As for the sink, this is not necessary, because you can completely hang a water pipe on the attachment of the algae, just keep the algae moist through the water pipe without completely soaking it in water.

If the conditions are better, it can provide a better foundation for algae dependence.

The German technology was to make hollow glass plates, connect supply pipelines and discharge pipelines to these hollow glass plates, and then inject culture medium into the hollow glass plates to cultivate algae.

At the lower end of a single hollow glass plate, carbon dioxide is injected into the culture medium as a nutrient through the supply pipeline to produce bubbles. The vortex formed during the bubble rise will stimulate the algae in the culture medium to absorb carbon dioxide and light, perform photosynthesis, and continue to grow and reproduce.

When algae grow and reproduce to a certain extent, the algae in these hollow glass plates will be recycled to harvest biomass.

According to the experimental data given by the Germans at that time, such a square meter of hollow glass plate can produce 900 kilograms of biomass a year, and about 10 liters of methane can produce about 200 square meters of methane a year. A 200 square square insulating glass plate can produce more than 600 cubic meters of methane a year.

These methanes can generate 4500kW/h electrical energy and 6000kW/h thermal energy for power generation, which can be said to be quite clean and efficient.

Of course, the Germans used fuel cells instead of simply burning methane to release heat to generate electricity, which was much more efficient.

As for Chen Xin’s current supplies, he can only use screens or other easy-to-adhesive things to make a base for attachment, then pour water on it and provide light to allow algae to grow.

Simply put, it is to build a simple device first, let it run first, and then consider upgrading it to improve operational efficiency and expanding production capacity.

All you need to do in making a simple device is a sink, a miniature vacuum pump, several PVC pipes and an attached facade.

After Chen Xin flipped through his own material storage room, he quickly found what to use, although they may not be so co-use and require some modification.

The size difference is much, which leads to the inability to connect the pipe and the vacuum pump. The sink is simply a plastic box, and the attached facade is also a screen removed from the windows of the container house...

Looking at these things, Chen Xin felt that he might have made a workbench for himself first.
