Electronics Seminar topics selection

i have the following topics in mind whcih i got from a website (edufive.com). I am not sure which one to go for ? pls help. Whcih is relevant & whcih one can give me good literature to develop my seminar.

Optical Communications in Space
Elliptical curve cryptography (ECC)
New methods to power mobile phones

Please advice.

I'm sorry, but if you have to look to web sites and forums to find a topic to speak on, that pretty much means you're not someone whose seminar I'd like to attend, no matter the topic.

Pick something you know and are interested in. You will make a much better impression, since you'll know what you're talking about. Picking a topic out of thin air and then trying to sound authoritative on that subject is a straight path to hell--but if you pick a topic you already know about and have an active interest in, your presentation will be much more powerful (and meaningful).

Thanks Torben ! What you are saying is absolutely right. I will start thinking on this line now. Thanks!
