This thing has to be taken seriously by him, because this thing is not general.

It may be very ordinary in Fang Rui's eyes, but it's just a battery, but the raw materials used in this battery are actually discarded garbage in daily life, or even biological excrement!

However, this technology presents a problem, the choice of catalyst is too poor.

No matter what the catalyst is, the efficiency is too low, and the cost is still very expensive, and the return to cost cycle is very long, which is not suitable at all!

However, because the prospects are too tempting, those talents will think of let Fang Rui solve this problem.

Fang Rui was also moved when he heard that Long Hua was willing to give himself a favor.

A favor of this person, it's not an ordinary value! This is equivalent to a country owes you a favor!

In ancient times, this kind of favor could be directly given to you, no, it should be said that it was given to you a city, or directly made you a superior!

Ever since, Fang Rui didn't even think about agreeing when he heard this sentence!

This is really tempting.

"No problem, Long Da is what you say. When I go, I am ready." Fang Rui immediately changed the preface and said, very shameless, very cheeky, this kind of spirit makes Long Huadu Not ordinary speechless.

"Let's take a look at taking time to pass, but it may take more time. Those people have more problems," Long Hua said cruelly.

Now that they are here, let them solve all their problems, or else I am really sorry for my personal feelings.

But what Long Hua didn't expect was that one day in the future, he would regret his choice...

In fact, the fuel problem was solved quickly, but the rest of the problems are hard to say. Longhua was also greedy for cheap, and wanted Fang Rui to give more information, but he didn’t know that the wrong way gave Fang Rui a greater favor. ......

"This is not a big problem," Fang Rui agreed.

In fact, Fang Rui now has a lot of confidence.

All the experimental data of those people are there, and all the problems are under Fang Rui's control. Now Fang Rui knows what the problems are. Anyway, it’s not too much, not too little. More than twenty questions before and after.

More than a dozen of them are about new inventions and new compounds, and the rest are about machine modification and how to increase energy conversion utilization.

In fact, in Fang Rui's eyes, the most efficient use of solar energy is what Fang Rui thinks is the most valuable thing. Fang Rui also subconsciously thinks that Longhua is asking him to solve this problem.

The current utilization rate of solar energy in the world is actually 21%, which is neither high nor low. Longhua estimates that the improvement of this cannot be improved much, so it does not care.

But the answer in Fang Rui's mind tells Fang Rui that the utilization rate of this thing can really be greatly improved!

"I'm leaving now." Fang Rui couldn't wait. Sometimes the process of solving problems was very cool, and he could use those ultra-high specification experimental instruments at close range, which was very comfortable!

No objection, Fang Rui also hung up.
