My son loves toy of the car, and always has a minicar in his hand.
The toy related to the car is bought without fail for him at the birthday and Christmas.
Talkin of toy cars, the most famous company is TAKARA TOMY in Japan, we call it ''TOMIKA''.
He has the circuit to make the Tomika's car run.
The car keeps running a high speed with a dry battery.and it is easy to go up the slope.
This car is really noisy....also the dry battery is died quickly.
Therefore, we decided to buy ''rechargeable battery'' which is remarkable one recently.
Panasnonic and SANYO manufacture a rechargeable battery in Japan.
It is usually sold in electric appliances store.
A rechargeable battery is set in a special charger, it ties to the outlet, and it will be completed in about three hours then the battery can be repeatedly used.
However, it should buy a battery that is not a usual battery but special.
These are adapter.↑↑↑
It finds it useful very much for my home as a battery for the toys.and I want children to grow up in recognition "The battery is not disposable".
Because at present, the dry battery sold in one year in Japan is about 1.9 billion.
Where how is the battery that finished being used going?
It is said that it is possible to use it repeatedly 1500 times if it is a rechargeable battery. moreover, because a natural electrical discharge is few, it will be possible to use it by charging it at once in one year.
The rechargeable battery of various packages is sold.
By the way, the rechargeable battery that Panasonic manufactures is called EVOLTA.
The robot made for the advertisement of EVOLTA is very cute.
It is a robot of the height 17cm that moves to the mainspring in 12 batteries. this robot was made by Mr, Tomotaka Takahashi who is the world-famous robot creator.
The challenge to which this small robot traveled around Fifty-three Stages of the Tokaido from Tokyo to Osaka got into the news for a moment.
check it out here his traveling →sorry only Japanese site here
When we bought EVOLTA battery, we got toy of extra.↑↑ yes he is the robot of EVOLTA.
It advances ahead when pulling it behind this toy.
My son loves this toy!!! this is his favorite one now.
Go green and care about environment it is always good, but... Where is your electricity coming from? (From fossil fuel which polluting environment or from nuclear energy which can be even bigger problem itself )
Another problem rechargeable batteries may be you don't throw away them as often as standard batteries but you will have to throw them away eventually and may be they will pollute environment even more then standard batteries due to the different construction and content of different rare metals.
