What an excellent article Loz - and glad you\'re still with us after your little incident months ago.

Why is its butt called the Mastera?

Loz December 21, 2011 03:23 AM

Sorry Ozuzi, my mistake, the Mastera is the Tempera\'s sister ship.

Nice article indeed! Just a question, was the azimuth thrust unit (or Z-drive) not already developed in the 1950\'s ? If memory serves me right, it was the founder of the schottel company in germany who made the first models.

Interesting article, thanks. How much does one kilogram of enriched uranium (and non-enriched) cost compared to the diesel (and how much would that cost?)

Thanks for taking the trouble, much appreciated. (A weekly in-depth item would be a good selling point for the site.)

\"Here\'s an example, the MT Tempera\" at first I thought the name was written in reverse on the other photo (just to confuse!) but reading your comment set things straight!
Have come across these before but nice to see such an informative (as always!) and well-written article on Gizmag.. Thanks!! ;-)
