There is no space left to reinforce the crane. It's already very high if you follow the total length of the crane.

I'm sure burj dubai isn't designed to electrify the steel floors, but how does the spire transfer the electricity from itself all the way down to Earth?

Yeah it does exactly what its supposed to do.

I was on a plane when lightening struck us!
it goes through the nose, down the cabin and out of the tall, the way it should.

just conducts it down to the ground.

OK, and now for something completely different.

Photosynths of Burj Dubai.

If you're not familiar with Photosynth, it's a very, very clever tool developed by Microsoft that automatically combines multiple photographs and reconstructs the 3D space in which they were taken.

This morning, I took around 200 photos of the Burj Dubai and the area around the Old Town. These photos have now been "synthed" together. The tool managed to connect around 140 of them, which isn't bad considering it's my first "proper" attempt at doing this. Note that this means there are quite a lot of "orphaned" photos though.

To view, you'll need either IE or Firefox, and you'll need to install a small download.

I did a couple of small synths yesterday in preparation to try to get the hang of it. If you're interested, I suggest you start with one of these simple ones first, before moving onto "the monster".

You can find the synths here -

http://photosynth.net/Search.aspx?query=gerald.d

"Burj Dubai large" is 9 photos, 100% synthy - i.e. the program was able to place all 9 photos in the same "space.

"Burj Dubai GD" is 17 photo, 75% synthy. There's one group of 12 photos, and one of 5.

"Burj Dubai monster" is 206 photos, 70% synthy.

Enjoy!

Cooool...

I've heard of this before, but as I remember one gives "them" permission to use the uploaded pictures/snths as they want (?). Well, who cares, right... Panoramio in Google Earth is just the same to some extend. And if I publish my pics I have to accept that they are public

Anyways, great idea! I am already thinking about trying it myself
