くの人は、日常生活の延長としてアウトドアライフを楽
しむようになってきている。Except for some people who believe in sports alpinism of "Aiming for higher and more difficult", many people are increasingly enjoying outdoor life as an extension of daily life, except for some who aim for high peaks.
このような変化に伴ない、テレビもアウトドア用品と

あり、特にナイター鑑賞を楽しみたい人々には役立た
ず、依然として問題を残していた。With these changes, televisions are also establishing themselves as outdoor products. The problem is the power supply. Color TVs that use liquid crystals use a lot of power, and when using dry batteries, they can only be used for a few hours, so they have to be replaced frequently, and the cost is high and it is not easy to carry replacement dry batteries. Deterioration of dry cells due to long-term storage has also been a problem. Therefore, although a device using a solar cell has been proposed, it cannot be used at night, and it is not useful especially for people who want to enjoy watching night games, and still has a problem.
一方、ろうそくをはじめ、天然ガス、石炭等の化石燃
