The other day, I found a news item about a novel wind power company, Motorwind. The product looks like a toy and is priced like a toy, but the output is anything but.
In the same spirit, I bought a toy to measure our wind resource. The September issue of Gakken's magazine has a wind meter for 1,260 yen, significantly cheaper than a 'real' wind meter at 12,000 yen.
I put the wind meter together with help from the young master, and we took the thing outside. Gratifyingly, the little propeller went around like crazy, and the reading immediately went straight off the paper cylinder dial. 4 is the highest mark on the dial, and this apparently equals a wind speed of 5.5 to 8.0 m/s. This is in keeping with the wind map for our area which shows an annual average of 5.5 to 6.0 m/s at the red blob where our house is located.
Apart from showing the wind speed, my toy was very helpful in showing the direction of the wind, south to north, which is perpendicular to the axis of the sun (as Lucien Gambarota of Motorwind kindly explained to me when I emailed him).
The Motorwind product that interests me costs $199 (21,000 yen). It consists of 8 micro turbines with a generator rated 50W for 10m/s of wind. Daily production is 1.2 kWh. That is amazingly cheap alternative energy, assuming it works as advertised.
I figure that a row of 8 turbines will fit nicely on one of the uprights of our balcony. Once the current is passed through a battery to set the voltage level, it can go into the grid in the same way as our solar generated power.
This is the sort of cheap, smart solution that will revolutionize renewable energy and free people from fossil fuel. If our wind power works out, I'll be aiming to promote this solution to all of our neighbours and friends.
With Inchodon on the roof of his clinic in Masaki-cho. The wind measured 3-4 - probably adequate for generating some power. However, since the clinic is in a very built-up area, there's concern about disturbing the neighbours with noisy turbines.
