Gao Feng's assurance naturally made everyone grateful, and his personality charm has risen to the extreme. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, Gao Feng didn't just want them to be grateful to themselves.

These people are the first group of people in the workshop, they started early, proficient in business, and worthy of their trust, and the future workshop will become bigger and stronger depends on them to support, so the peak is very willing to invest in them.

Improving his life was only the first step, and there were more reliable ways to follow, and he didn't believe that anyone would betray him.

After a turn in the front yard, Gao Feng took a few people to the back of the house, where a closed pool was built behind each house.

Luo Fu asked puzzledly, "Big Fang Master, why do you have to go to so much trouble to make this cesspool?" ”

This pool is connected to the toilets of each family, and there are a few mouths reserved, and at a glance he knows that there is no other purpose, but he really can't think of what it is for, so he asks.

Gao Feng smiled: "Don't underestimate this pool, it can have a big use, so let's say, whether it is fertilizer, or life use, it is inseparable from it, but unfortunately I have no perfect conditions now, and can only be used as a septic tank temporarily, but I tell you, once the conditions are ripe, I guarantee that you will be eye-opening." ”

And this kind of thing? Everyone looked puzzled, to say that a manure tank is understandable, but it is a bit ridiculous to use it in life, whose life uses such a stinky thing?

I don't understand it, but Gao Feng still briefly introduced it.

"The pond will produce a very useful thing in the process of accumulating fertilizer, this thing is called biogas, biogas is not a general good thing, it is not only bright after ignition, but also has more heat, there is no pollution, it is irreplaceable for cooking and lighting."

"Is it brighter than a candle?" Luo Fu couldn't help but ask. He also asked everyone's thoughts.

No one cares if this thing can cook, but the lighting is different, the best way to illuminate nowadays is candles, candles are not only expensive, and the brightness is not high, if this thing can be brighter than candles, it is a good thing, this kind of question is also a comparison.

"It's at least dozens of times brighter than a candle, and it's extremely pure, without any smoke, such a lamp is called a biogas lamp, do you think it's good?"

The biogas lamp is equivalent to a 100-watt electric lamp in later generations, and that brightness is indeed incomparable today.

It's so powerful! A few people were taken aback, if there are a few lights installed in the house, no, it is to install a lamp of this kind, the effect will be unprecedented, it is incredible to think about it, not to mention that Gao Feng said that it has other uses.

"Do you still need to invest in the later stage?" Luo Fu asked again.

This is also what he is worried about, such a good thing, if you invest too much money, you can't afford to use it, it's better to use a small candle.

"This is a profitable business, an investment, long-term benefits, as long as the pool does not collapse, only need to regularly inject wheat straw, dead leaves, straw, human and animal dirt in the future, so it can not only be used as waste, but also keep the environment clean, and more importantly, it accumulates better fertilizer efficiency, this fertilizer can definitely increase the yield of crops in the field by three percent."

Oh my God, this is too terrifying, except for the initial investment cost, it is earned inside and out. With it, not to mention that the home is brighter, not to mention that the cost of lighting is saved, it is incredible to increase the yield in the field by three achievements. The output of this thirty percent can get the cost back in just two or three years, and the rest is earned, as Gao Feng said, it is a good deal with a lot of profits, and it is indeed cost-effective.

Hearing this, the eyes of several people were full of eagerness, and they couldn't wait to use this biogas digester immediately.

"Why can't you use it now?" Luo Fu asked again.

"Isn't that obvious?" Gao Feng replied, "Everything else is easy to say, the only thing missing now is the gas pipeline, and how to send the gas to the home is the key." You all think about it and see if there's a good way. ”

As soon as this question was raised, it made everyone loosen up the momentum, and everyone was speechless for a while, not knowing what to do, after all, the sealed gas pipeline is really difficult to find.

"Can you use beef intestines or horse intestines?" Old Sun Tou proposed.

Gao Feng nodded, this was indeed a method, but he didn't agree.

Not to mention the strict control of the hunting and killing of cattle and horses, it is very troublesome to deal with them by virtue of their animal internal organs, easy to weather, hardening, perishable and deteriorating, these are its shortcomings, and if you can't overcome these, you don't dare to use them at all.

"I already have a solution, but it will take some time, and you don't have to worry about it." After saying this, Gao Feng said: "In fact, these pools still need to accumulate some mold, only the number of mold can produce a large amount of biogas, so everyone usually opens their mouths to make it easy for mold to enter, I think when the pipeline comes out, the mold accumulation is almost the same, and then everyone can use environmentally friendly and hygienic biogas." ”

Gao Feng said yes, and everyone naturally believed it, but everyone still didn't understand the mold he said, so they couldn't help asking: "What is mold?" ”

It took a lot of time to explain, Gao Feng shook his head in annoyance, and still said: "The rot you see is caused by mold, and only with mold can those filth produce methane gas due to decay." ”

"Is there a lot of mold? Why open the mouth and they can get in. ”

"It's all over the place." Gao Feng pointed around and said exaggeratedly.

"Ah, doesn't that mean we have it in front of us, but why can't we see it? If there is mold everywhere, won't we be eaten sooner or later? ”

"Mold is invisible to the naked eye, to say that it eats people is not so scary, as long as we usually pay more attention to hygiene, we can still reduce its existence, mold likes rotten things the most, where the fastest reproduction, so there is garbage or dispose of it as soon as possible."

……

He even considered instilling some popular science knowledge in the future on a regular basis, so that everyone could think about thinking about problems from a materialist point of view, instead of looking for immortals if they couldn't explain it.

With popular science knowledge, everyone will gladly accept the importance of hygiene and care for the environment, and even feel that they start from themselves, relatively speaking, this is the main purpose of the peak.

If it is said that the treatment of workers only needs to popularize science, then the students of the Education Society are ready to explain scientific and technological knowledge to them. Physics and chemistry will be the top priority of the explanation, and he is also thinking about writing a set of physics and chemistry textbooks while he is free at home.

These students are not yet in the climate, but he is confident that under his education, he will definitely be able to take the lead in three or five years, and he will be much easier at that time.

The follow-up will be said slowly, but Gao Feng rode south alone the next day, and he wanted to solve the doubts in his heart today.
