Floating Wind Turbines

As Japan announced that it will become a nuclear free country by 2030, the Japanese government has started to approve a series of measures to start developing alternative energy sources. Here in Japan solar energy is not viable as there’s almost no space and most days throughout the year it is cloudy.

Wind energy is the alternative that seems the most feasible for the country but the lack of space makes it difficult to build the amount of wind mills necessary to produce enough energy. Apart from the typhoons that come once in a while, Japan is not a very windy country. There are very few places that have continuous winds above 6~8m/s.

In the following map you can see the areas that have more potential to develop wind energy sources; almost all of them are in the sea!

The solution that Japan is going to adopt is to build floating wind energy farms. The first experimental wind turbine has been built in Norway but Japan and United States are the first countries that are going to build fully operational wind farms. The United States floating wind energy farm will be located in the Maine gulf and the Japanese 1GW farm in the Goto islands (to the south from Nagasaki). The Japanese plan is to have the wind power farm completed and operational by 2020.

This is one of the standard models proposed in Japan; it should be designed to withstand the destructive power of typhoons:

And these are other proposed prototypes that are being built right now by Gicon, Hywind, Blue H Technologies and WindFloat:

Kabutom RX

It is 11 meters tall, it weights 15 tons and its creator, Hitoshi Takahashi, has been working more than ten years building it. It is called “Kabutom” because it looks like a kabutomushi, a beetle which is owned as a pet by many Japanese children who love to play with them.

Kabutom

The first version was the RX-01, and the last version is the Kabutom RX-03. It can be piloted from its cabin or it can be controlled by remote control:

In these videos you can see that it looks quite clumsy when it moves (it uses wheels to move). It reminds me of the mechanical spiders created by the french group La Machine.

Working with a Sony Head-mounted Display

A Mixi engineer recently bought a HMZ-T1 (Sony), possibly the best Head-mounted Display in the market. But instead of using it to play video games or watch movies he is trying to use it to work. One of the advantages is that you can work in any position!

Morimoto uses glasses, so in order to be able to use them with the HMZ-T1 he had to do this little hack.

The problem is how heavy the gadget is, it seems that after working for a while horizontally your forehead will look like this:

This time the solution was more complicated than solving the glasses problem. He decided to work again in a vertical position and set up a device that supported the head-mounted display so that the head didn’t have to hold all the weight:

I feel like I want to try this Sony gadget to see how it is, it reminds me of the Nikon up300 and I guess it is much better. The Nikon head mount display had only one display and when I tried it I remember that it made me sick.

I can see the future
