We joined the wind power generation competition.
　


We were able to exceed the quantity of generation compared to last year in the competition, but we were not able to win a higher prize.　（But we still received a prize for ithe idea like the last year.)

It is a method that the contemporaneous type sets up two hub dynamos and ties a rectifying circuit to other participants.
It was a quantity of overwhelming generation.

We must think about measures for a next competition at once.

Junior high school students were competing against high school students and technical school students. It is technical and does not match it in as to knowledge. So we asked the technical school and the university for technical cooperation next year. And we will enter the competition again, please look forward to the result of the next year.

We are going to participate in an article contest after this. We were very glad to be able to show a description of the production to all of you by participating in a Web contest.

　Please pay attention to the natural energy research group of the Tkoyo Metropolitan Koishikawa Secondary Education School in the future.


Thank you very much.

On the eve of competition

We started the production of the windmill about for half a year and we experimented on a wind tunnel.We confirmed a thing beyond the quantity of generation of the last year. We play with this body this year.

(K) A windmill・windtunnelproduction and a theory.
(Ukai)Technology.
(nats) English translation,document collection.

We shared it well and accomplished it while we were busy with English study tour.

We want to challenge it next year!

Charge circuit

Let's use it,because we generated electricity with much effort. We made a charge circuit.We would be happy if helpful for all of schools.

Windtunnel equipment

The wind tunnel device became malfunction-prone by use of the day after day. It is a break time until the midterm examination end.
October15th,2014
Karman's vortex was confirmed.


We tested it with various blades,so were finally decided to a dragonfly's blade.And We added a Wind collection device.

Trial and error


We are during trial and error for competition.Left film is history of the works.（ The exhibition Japan University ）　
　　　　　　　









You can try preliminary experiment by easy wind tunnel equipment of Japan University.

EXPO

I went to Tsukuba again.This time,We studied film editing.

One of the world's largest planetarium! We recommend it.
September28th,2014
We went to Tsukuba.

We finaiiy went to study in Tsukuba since this summer.This town is nice town that we can learn in the whole town.

We succeeded in photography of the flow of air.



The flow of air hitting the wing-shaped blade…。

Blade of electric fan to see from wind tunnel's honeycomb

We never get tired of looking at this view.

we cut a tub
We made the wind lens which we could expect of wind collection.We cut a tub of bottom of diameter 80cm.
September16th, 2014
We finally installed it.
We instituted windmill on the three floors in school.
It is a whole year measurement plan with quantity of generation.

Creativity exhibition

This is school festival. we are performed a short drama every class. (K,Ukai,Nuts)
Research on natural energy team exists in physics room side silently.

Pyramid

This pyramid has eight steps. Under step is very hard.We are continuing a wind tunnel experiment in the interval of the athletic meet.　　
September9th, 2014
We sing enthusiastically
　　　
　　　　　　　
We sang "We Are The World" enthusiastically! Memories in Australia cross our mind.(At the Hibiya Public Hall)

September5th, 2014
We are absorbed in wind tunnel experiment.
First,"What kind of blade is good?"We test it in our members.We look for a blade turning ground in the low wind velocity well.

We ignore the resemblance rule of Reynolds.
September1st, 2014
Starting in earnest
Research on natural energy team begins an activity.We brought in the wind tunnel which (K) created by himself here.A hedquarters is space of the physical room side. And,We are looking for something with the effective blade every day.
