latest electrical subjects

Sure (but please don't talk in txt language. Please. It is very unprofessional). There is an exciting new development utilising the nature of quantum physics to transmit data down a data line instantaneously, regardless of cable length (yes I do mean infinite speed).

I don't know how much help this will be as you probably have absolutely no idea what I am talking about (you did ask for LATEST electrical subjects). I suggest you have a look at the engineering and science newsgroup on the internet to get some ideas regarding current developments in the fast and ever-changing field of electrical engineering. Older technological developments which are still being refined and tested also include matter teleportation (as I mentioned above), artificial intelligence and superconductors (which have all been around and working even before I went to university).

Oh, then there is one of my favorites (we are a military contractor after all) - Electromagnetic armour for dissipating plasma energy (generated of course by explosives and electrical arcs), the first true electromagnetic energy system (which the average person would call a "shield"). Information available on this subject is a little restricted however (for obvious reasons), so will likely NOT be suitable for a seminar (and outside the scope of a 4th year engineering project). The less said about current developments in plasma-based and electromagnetic weapons the better (better steer clear of these).

Welcome to the REAL world of engineering development, it is a hell of a lot more exciting, complicated and terrifying than you may believe (and people say engineering is boring).
