Abstract: An electricity-generating system of the invention which includes the following: a carbonization apparatus for carbonizing a carbonization source to form a carbonized product; a heat recovery steam generator for producing first steam through heat exchange with the heat exhausted from the carbonization apparatus; a carbonized fuel steam generator which employs the carbonized product serving as a fuel; a mixing header for mixing the first steam and a second steam produced by the carbonized fuel steam generator, which steams are fed thereinto, to thereby discharge a steam mixture having a uniform pressure; an electricity-generating apparatus for generating electricity by means of the steam mixture discharged from the mixing header as an actuating source; and an electricity-storing apparatus for storing the electricity generated by the electricity-generating apparatus.

Abstract: A plurality of columns are erected with predetermined spacing on a groundsill. Then, a wall panel composed of a plurality of paulownia plates laminated, with the grains of the paulownia plates being crossed, is fixed between these columns. One surface of the wall panel is used as an external wall and the other surface of the wall panel is used as an internal wall to form the walls of the wooden house.
