That Germany was at such risk from a Tsunami or Earthquake.

I still don't understand why everyone is so up in arms about Fukushima, it got hit by a giant surge of water that leveled most towns and it was, for the most part, pretty fine. If anything it should be an endorsement of the technology.

Wouldn't it be easier just to make sure that cars' throttles don't get jammed or stuck?

Seems to be the thermal decomposition on ZnO
Zinc Oxide --> Zinc + Oxygen

Followed by the reduction of water:
Zinc + Water --> Zinc Oxide + Hydrogen

If the Zinc Oxide is reusable that's pretty decent, but I wonder how it compares energy wise to other methods of water separation.

A) You can't assume every child and parent has access to the internet or computers. I work in a fairly normal catchment area of the UK and I'd say there are around 10% of families that fit into this category.

B) Too many excuses. You set homework online or through dedicated software and the pupils come back with 1001 excuses - "broadband wasn't working", "I couldn't download it", "it was in the wrong format", "printer was out of paper", "I've got it on memory stick and it still needs printing" All easily check-able and solve-able individually but not if you have 30 students. Give a child a piece of paper with homework on it, and if they lose it it's their fault (they could have come and collected a new sheet before the lesson), and if its not done it's their fault. Much much simpler.

Transparent screens still make me all fuzzy inside, but gesture based UI just doesn't interest me in the slightest. I want a UI where I have to move as LITTLE as possible. There was nothing on that demo that wouldn't have been easier with a mouse and a couple of mouse buttons more accurately, quicker and with less movement.

Reduction in skin pain seems very useful when you're at a much higher risk of sun burn.

"Everyone should understand that when they add their friends to Facebook, they are doing free work for United States intelligence agencies in building this database for them."

Excellent, so by playing Farmville I'm not only reducing my taxes (because they'd build the database anyway), but also contributing to the safety and counter terrorism efforts of my country.

It's not only addictive, but patriotic.

Go EASY on your EBE's

..Class size? As a science teacher, I fully agree with all the comments about the difficulty of firing teachers, and the effect of teachers of pupils performance, BUT in terms of my own teaching - if the school cannot afford enough teachers and class sizes are made larger - not even the best teacher in the world can make that much of a difference. On the other hand, fewer students with even a bad teacher will do better. Also, the government (UK in this case) should stop changing the sylabus or current faddy pedagogy and let teachers teach the same thing for more than 3 years. Just when you start achieving results with whatever they have decided is the 'next best thing'(TM) they change it.
