This is one such volunteer and this is a device that he had built in the village where he worked. And the idea was that you could take waste paper; you could compress it and make briquettes that could be used for fuel.
이 사람이 그런 자원봉사자이고, 이게 그 사람이 그가 작업했던 마을에서 만들어낸 장치에요. 폐지를 모아 압축해서 연료로 쓸 수 있게 연탄같은 걸로 만드는 거였죠.
