Well, let's start by saying that Mario Rinvolucri may be (in)famous, but he doesn't have to be 'one of the foremost methodologists and teachers in the world of ESL' to everyone, even if the speaker there feels he really is.
In all fairness, however, there are at least a couple good ideas to be found in his books, and as for his

one, in a way I admire teachers like him who can think up and fearlessly present or spin stuff (crap?) like that, and you could argue that it is a good way to "affectively" elicit a bit of vocabulary that some students might never have encountered, thought of, or thought about. Tall trees from small acorns grow, with enough froth from the teacher and tears (from falling about and laughing hysterically at the suggestion?) from the students.
BUT if it is not made very clear to the students that people do not, in fact, hesitate much before turning on a light, and that nobody, certainly not outside of ESL classrooms, sits around seriously discussing "switching" and their thoughts about it*, then I really think such "methods" are verging on fraudulent if they claim they are teaching English - English to what ends? Communication from what starting point? Nobody using those methods is going to make it clear to the students because they fear the question that the students would then almost certainly start asking (even if the students didn't immediately and from then on always object to the sham): 'Well, why don't you just teach us how people really talk, then?'. Many teachers fear that question, especially the "just", because answering it would mean an end to their comfortable careers and easy existence.
Even a moment's reflection will tell you that what actually people say in connection with the topic of lights is not to do with e.g. the environment (one of the likely "thoughts" that Mario's activity will produce), and if the environment really has to be a hot topic somewhere in the
course, perhaps it would be best mentioned in relation to collocations such as 'protect' (and I would probably prefer only in
incidental relation to 'protect', if I had discovered that environment was a common collocation and thus a good potential context for 'protect', but the
topic is not one that I would more or less directly foist upon my students, I mean, we can all see where Mario is headed here, right? Save the whales, save on thinking about what English the teacher should be thinking of, and thinking of
before the class, not always just in it and in response to a student's faltering and perhaps faulty suggestions).
The next activity, about emotions eliciting memories, has a lot of potential, but again, not much thought is being given to possible problems with language. I mean, just what does "reverence" mean? Will all the students who don't understand it necessarily be any the wiser after hearing another's story? And will the tellers themselves be showing a proper understanding? To be sure people that knew the meaning of
complex emotions, you could of course ask one person at a time to tell the whole class a story (so that
you can hear it clearly), but you might then be in the awkward position of having to correct them if they hadn't, in fact, showed much understanding in their telling.
So, this isn't perhaps the best way to "teach" potentially complex words, it could be encouraging students to run before they can walk, and maybe try to outdo each other, and as in the first activity, is not made clear that people do NOT always state (just) an emotion word and only then relate a story, often it will be vice-versa, and then, the emotion is not always made explicit or, if explicit terms are mentioned, they will be provisional and could well be negotiated or rejected
in the natural process of the telling itself (and not by a red-faced teacher after all is "said and done").
Here is a point where the teacher at least should be looking at real discourse and trying to formulate realistic aims
that will result in some genuine learning, if we get too ambitious then little may come of it (that's not to say that some classes can't and don't benefit from "fluency" activities, but even these high-level students might "like" to take a look at some real discourse from time to time, instead of always having to invent it themselves moment by moment, immediately after which it is usually lost forever and cannot therefore be subjected to any analysis itself).
Example 4, "interesting", but again, where is the
language the students need to "respond" to sounds? Do they just say the noun they think ('bell?'; 'stuffed lucky hamster keychain'? Oh sorry I thought that by "resonant" he meant ones that would resonante in people's minds long after seeing them or hearing anecdotes about them, rather than simply in their ears for only a short time

)? How is the guessing to be linguistically expressed, exactly? Is there a dialogic process applicable to REAL situations outside the classroom that is here being missed (A: What the **** was that?! B: Maybe MR letting off wind? vs. Teacher: What's this? <<BONG!!>> Student: Bell? Teacher: Make a question! Student: Ah, sorry...is it a bell?)? I'm sorry if I appear condescending, but usually even the most
basic of basic questions simply are NOT being addressed by the methodology (and where is the APPROACH, linguistically?!).
You must admit, the risk is there of, certainly less experienced or less thoughtful teachers taking what they presume is a well-thought out but actually rather glib set of instructions and using a Simple Present basis for sounds, when Simple Present might (if we liked the "idea" of a guessing game) more involve a present giving exchange (A: I hope you like it. B: Ooh, what is it? Hmm, is it/
could it be (impossibly expensive item, joking, hence the 'could' just then as opposed to a more straightforward 'is', not that 'is' is necessarily "wrong" here, but do people really use 'is' that much to ask about presents they could just as easily open? Wouldn't to do so, in a less jokey way than 'could' affords, risk offending the giver if the "guess" were wrong? Hmm)... [?Can it be...]). But then, I suppose the activity stockings are already filled to overflowing with variations on the tired, old and linguistically undemanding, no-brainer of a 'What have I got in my hand/in the bag? Is it a pen? Is it a pencil?' routine, bet the adults love that.
* What more can there be apart from, 'Electricity is wonderful invention', 'I must switch this off as soon as I'm done and save electricity', or 'This can't be doing the environment much good, maybe we should just sit in darkness until the sun comes up like animals have to', to arrange them in an airy-serious order? To try to elicit more could get painful, unless "humanistic" classes actually like getting into the very human concerns of what goes on when the lights go down - 'Leave the lights on, honey, I want to see you doing it! Teaching in the full glare of fluffyhamster's spotlights, that is'.
