Solar Twinsaru
Do you want to educate children to help reduce global warming?
We have developed a new product, Solar Twinsarus. This educational model teaches children solar power generation system. This model generates power from two sources: infrared and visible light. Visual light (solar battery) is commonly used but this model also has infrared ray to create power. This educational project helps reduce carbon emissions and reduces global warming. A better way is needed to decrease oil use for the future.
Sales for this product started Feb. 2009 in Japan. Since then, over 1,000 have been sold. Elementary schools to universities have bought this product for educational purposes. 70% of purchasers have donated to schools, e.g. Rotary, Lions Club, Kiwanis and other charitable organizations. The other 30% has come directly from school’s budget.
It is very important to create green energy. From this principal educational model, children will be able to learn and be excited to take part in our future green development.

Solar Twinsarus is a children’s educational miniature model for teaching solar power generation; a new eco teaching model. It demonstrates two sources of solar power, Infrared and Visible Light, developed by JAXA (Japan Aerospace Exploration Agency).
►What is the Twin Solar Power Generation?
The twin solar power generation is a power generating system that efficiently uses the sunlight that JAXA (patent pending) invented. In the past, infrared was not being effectively used for solar power generation. This concept is presently being set up in Inner Mongolia where there is good sunlight and continuous research for actual use. Solar Twinsarus is a teaching model using the principle of sunlight combined with cycle power generation system. Solar Twinsarus can provide children solar energy power experience. And children can learn the power generation from sunlight and heat.
►Principle of sunlight heat combined cycle power generation system
 The sunlight collected by the lens is separated to "Infrared" which has long wavelength and "Visible light" which has short wavelength. Then electricity is generated by using an independent power generation module. (See right fig.) A separate motor is moved by electricity generated by solar battery and the thermoelectric device by Twinsarus.
Will not work with indoor lighting or on a cloudy day.

THERMOELECTRIC DEVICE:
This device is made by two special metallic boards fused together When the temperature fluctuates on each surface, electricity is generated. |
THE WAVELENGTH SEPARATION FILTER:
The filter is made of plastic, half mirror film specification. The visible light (short wavelength) reflects to this filter and the infrared rays light (long wavelength) penetrates to this filter. |
►Power Generation Output (at blue sky and approx. 60˚ of the sun from horizontal plane).

 |
The experiment to which electricity is generated by using visible sunlight and energy of sun’s heat can be done. The solar battery and thermoelectric conversion device generate electricity when taking it under the sun on a bright day making the two motors turn. |
The experiment in which electricity is generated by heat can be done easily. The motor of thermoelectric conversion device begins to turn when hot or ice water is put in the mug (included in the product) and put on the optical board. |
