Gib, I didn't put two and two together. Indeed I recall Electrical Engineering I [twice], and your father now that you mention it. Some things are best forgotten. No, I didn't know we'd met!

Sediment transport modelling! Wow, sexy!! I worked on the Upper Waitaki canal construction [soil testing] with a friend, Vaughan Whitlock, who also supervised construction of the Ruahihi canal.

I tried to sell the Ruahihi people bitumen to prevent leakage - I'd driven along the canal and looked down the steep slope and thought is was a heck of a long way down and any leakage would NOT be good. They didn't buy my bitumen. I didn't know Vaughan was on the job or I'd have hassled him. I was only doing them a favour anyway as the sale was trivial and if they didn't want it, no skin off my nose, so let it go when they didn't reply to my letter.

My guess was right and they should have lined it with my bitumen to stop leakage, high pore water pressures, piping and collapse. Down it went in a spectacular flood and a kilometre [or 500 metres maybe] of canal destruction. I came down the highway half an hour after the collapse on the way back from Hamilton. That involved a LOT of sediment transport in a short time.

There you are, some old stories.

Ah, the good old days.

Sediment transport is fun! Knock yourself out. Anyway, what sediment are you transporting?

So I asked Google and got some interesting stuff. Modelling lymph and the immune system; cool. We have had an up close and personal interaction with our son's immune system with Non-Hodgkins lymphoma [back in 1997 so hopefully over and done with]. Any work on that is a good thing in my book. bioeng.auckland.ac.nz

We also had an up close and personal interaction with the sympathetic nerve system by way of our youngest getting a neurofibroma on a cervical ganglion a decade ago. [We seem to draw short straws]. Thinking about the effects of that, combined with my interest in CDMA and wireless cyberspace led me to the idea of nerve transducers for data input to mobile devices [instead of texting or poking at tiny keys]. What do you know, somebody is working on it [though not for that purpose though monitoring the sympathetic nerve system]http://www.bioeng.auckland.ac.nz/projects/telemetry/telemetry.php

I say patent nerve transducer input to CDMA cyberphones. Just move lips, tongue and larynx muscles, record the movements with implanted transducers and feed them into a processor in the cyberphone for super high speed data input. That should be a LOT better than voice recognition systems due to no confusing extraneous noise, but that's purely a guess.

Do you think such a nerve transducer system would be doable? Recharge the internal battery with inductively coupled supplies during sleep or maybe just use external transducers glued on. I don't know how sensitive transducers can be, but sharks seem to detect electrical flows from a distance, under water no less. ECGs and brain monitoring seems to involve sticking the transducers right on the skin.

Maybe we could wear a hat with transducers in it and measure the brain's electrical activity directly and teach the system what signals represent which words or letters, numbers etc and cut out the middle man [sympathetic nervous system, tongue, larynx, lips etc]. Cut straight to the chase and go to mental telepathy.

Want to send message to buddy. Think the message. Transducers pick it up and beam it over wireless signals to buddy's antennae. Buddy wears cochlear implant, or in-the-ear Phonak hearing aid, and heads-up retina scan. Receives signal, sees the video, hears the commentary, reads the web page. Replies in kind.

People sitting next to them have no idea anything happened. They don't need to disturb anyone, leave the room or anything. Being in a noisy environment would be irrelevant.

I think that system would be an excellent thing.

Will engineering become a point and click profession?

Nowadays we can run the stuff in a PC and it is far from when we have to use analog devices. You'd need real knowledge to do stuff.
