Where is your money on ink?

Have you ever heard that your inkjet printer crazily waste ink inside? Whether you have or not, today I've had the opportunity to take apart some printers and I want to show you.

The first candidate is and Epson. The complexity of the mechanism is high, and it's a heavy printer. Does it waste ink?

Yes, it does. A lot.
What you see in the pics is a 5 mm layer of muddy ink. It covers a reasonably large amount of surface in the bottom of the printer. Moreover there are thick, very dense, fiber pads all around to store lots of ink.

There is even a pump that suck ink from the heads and circulate it to the pads through some tubing... I'm glad I no longer use those inkjet scams. This is upsetting.

I also disassembled an HP. The engineering here is far simpler, weights less, does the same and is less noisy.

In the pictures it can't be seen very well, but in comparison, there is little place occupied with wasted ink in the HP. There aren't neither large pads nor pump.

Personally, this is not much of a surprise. Even without taking anything apart, I knew I was being scammed when I used inkjets.
It seems here that HP waste much less juice than Epson, but anyway I'm sure there is no need for this.

If you want my advise, get a laser one.

The weird building

First of all, the difference between a house and a flat is pretty much all my knowledge about architecture. However, I'd like to show you and comment this building I've found.

This is the School of Telecommunications Engineering, in Valencia, Spain.

What made me stop was that "network" that covers the front of the building, it looked weird and fantastic. Firstly, I checked the distribution of the vertical stones, because it seemed to be randomly placed, and that couldn't be possible. Indeed, I was right. You can see the patterns with a little of observation.

I went nearer to see how it was held there, and more weirdness... If you look close, you'll see the long horizontal rows are made with several short stones. The vertical stones are joint to the horizontal ones. NEVERTHELESS, the horizontal ones are neither joint to the sides of the building nor between them! Crazy!

So!, how is it held? It seems to be attached to the top and to the center part of the building at very few points. This stone network is ALMOST FREE!

But not only that. The rows are noticeably inclined to the front besides.

It definitely is more exciting to see in reality than in pictures. As far as it doesn't fall and kill everyone, good job.
