Here is a potential home savings solution for you, something from Panasonic. Panasonic, together with Tokyo Gas has reportedly launched the Ene-Farm Home Fuel Cell, something which should generate energy for homes while achieving an impressive 95% efficiency.
Said to be the world’s most efficient fuel cell, the latest version is said to be smaller which makes it easier to incorporate in homes. It also features a backup heat source which has now been separated from the hot water unit to broaden the space options where it would be installed.
The newest Ene-Farm fuel cell from Panasonic reportedly costs $22,600, cheaper than the older one but definitely still very pricey.
