I would just like to say something about drugs first. They allow you to know yourself for to know thyself is to know the universe and God. But to put this statement in context, all is one, you are an inseparable part of everything. You just do not realize this. Drugs help breakdown preconceived notions, limitations, and allow your perspective to shift allowing the direct experience of the truth. However without either a stable mental state or a metaphysical framework knowledge going into it, you may misunderstand what you think you think you know about how things work, hence the 'crazy' side effects on some people.
If you want to experiment with something that would radically and suddenly alter your perceptions such as drugs I recommend taking it slow regardless. But know this, everything you can do with drugs you can do with meditations as well. Drugs just give you a glimpse well beyond where you are know.
>Supposedly, you first experience ego death, then travel to a world of fractals and these weird extradimensional elves bounce towards you
On acid I've had the fractal experience. (I experienced ego death prior with out drugs.)
>I'd love to try it and come back with some specific technology.
There is plenty of inspiration to be had, even with fringe tech if you are willing to look. And given your rather stout resolve not to use drugs I would recommend a search engine. There are a lot of people working on a lot of very interesting things out there. Here are some links to get you started.

That should get you started and give you enough search terms and information to be able to build some basic proof of concept working scale models.
>Portal technology in particular I think would be invaluable to mankind.
That is quite an advanced tech, especially for physical bodies, however not impossible. I've only seen a little on the technological (non-consciousness based or controlled) application of it, see

If portals tech is your passion, drive, and purpose then in life and not just wishful thinking, good luck and keep us informed on your research notes and experiements. There is quite a sore lack of people publishing results online. Also know this, opensource is the only way, do not try to patient it. It won't work nor will the results be pretty, for many reasons.
