When he says "no one understands" he is excepting the speaker. Obviously the speaker understands what he is saying. Just a few verses down he explains:

The person in verse 2, the one speaking in his spirit, is the same person in verse 16 who is giving thanks in his spirit. The person speaking in his spirit knows that he is giving thanks, only other people can't understand what is being said. This flies in the face of the Charismatic teachers who say that even the person speaking in tongues doesn't know what he says. Well, Paul just said he does. True authentic tongues is understood by the person speaking. It is not a heavenly language only God understands. It is not a prayer language. It is a language that other people who speak the language understands. And even if no one in the congregation understands, the person speaking knows that he intended to give thanksgiving to God.
We need to bring all the verses to the table.
You say that you want to review the scriptures but the fact is, you won't find a scripture that makes the point you want to make. You already know what you want to believe; you have been handed a belief system to defend; and you have been told what verses to use during your apology. You already know what you think is true; you simply make the verses say it. There is nothing in the text where Paul says that someone with the gift of interpretations is required to interpret the gift of tongues. He doesn't say it explicitly and he doesn't even imply it.
Without any interpretation, only the person manifesting this kind of tongues is edified. Here is the scripture:
v4 He who speaks in a tongue edifies himself, but he who prophesies edifies the church.
When interpretation is God's will and the Holy Spirit empowers another with the gift of interpretation, then all who are listening are also edified.
The way you explain it, you even appear to set God against the Holy Spirit. The Holy Spirit wants to give the congregation a message but "oh well . . ." I guess if God doesn't allow it, then the message will just have to remain undelivered. The Holy Spirit wanted to say something through a faithful tongue talker, but God wouldn't allow it. The Holy Spirit gives someone a message to deliver but God thwarts the Holy Spirit's efforts. What a shame God and the Holy Spirit can't get along with each other.
Obviously when Paul says there are many kinds of tongues he isn't saying there are many different kinds of the gift of tongues. He isn't suggesting, as you do, that there is one gift of tongues for personal use and another gift of tongues for public use. He says that the gifts are given to be used to build up the body of Christ, which is a public, communal activity. There is only a gift of tongues for public use. What he means by "kinds" is to say that each gift is personalized to a particular person with a particular mission.
We both agree 100% of another "kind" of tongues being experienced in the Acts 2 chapter. This form fulfills 1 Cor 12:10 as there being different "kinds of tongues".
You say there can be 100's... well, the scriptures point out these two kinds for sure.
In a sense there are many "kinds" of Apostles. Paul refers to himself as the Apostle to the Gentiles, and Peter as the Apostle to the circumcision. The gift of apostleship wasn't of a different kind. Each man was faithfully teaching what Jesus taught with a high degree of fidelity under the inspiration of God. It was the same kind of thing in that sense. But each man had a different sphere of influence, teaching in a different area of the world from each other. The idea was to spread the gospel to everyone. But not everyone responded to Peter and not everyone responded to Paul. Some responded better to Apollos, and others responded better to Barnabas.
Likewise with the gift of tongues. The gift of tongues is the same no matter who uses it and for what purpose. But each person whom the Holy Spirit uses in this way is speaking into a different crowd of people, into a different historical context, dealing with different issues, and cultures, and expectations. To the extent that there are different kinds of people, living in different areas of the world, ministering to different groups of people, to that extent there are different kinds of tongues. But they are all public, they are all languages that can be understood, and they are all intended to bless and encourage and educate and give moral training to those in the church. There is no such thing as private tongues or personal tongues or prayer tongues. The gifts aren't given to people; they are given to the church.
