acostumbren a la luz no pensarán
en mirar las lámparas, igual que
al sol. El dinamo-generador que
suministra electricidad es la patente de Brush, y se encuentra en
la fábrica de la compañía Wolverine, donde es impulsado por la
energía hídrica. Alimentará dieciocho lámparas.
La fábrica de la Wolverine Chair
and Furniture Company es la estructura
roja que está a la derecha de la figura 6.
La luz de Brush era una lámpara de
arco y, por ende, demasiado brillante
para iluminar cómodamente pequeños ambientes interiores. Edison había

demostrado la iluminación eléctrica
incandescente práctica el 31 de diciembre de 1879 y la instaló en el crucero
S.S. Columbia en abril de 1880, pero
aún no estaba disponible al público en
julio de 1880.
A través del censo de 1880 en Estados Unidos, se determinó que Grand
Rapids tenía una población de 32,016
habitantes y que "tiene una inmensa
energía hídrica, la mejor del estado, y
una de las mejores del país, puesta en
uso por dos canales, uno a cada lado
del río". La madera aserrada y la fabricación de muebles representaban el
48 % del capital invertido en la fabri-

cación. La Grand Rapids Electric Light
and Power Company, la primera de este
tipo en la ciudad, se estableció el 22 de
marzo de 1880, con William T. Powers
(1820-1909) como presidente. Powers
nació en Bristol, New Hampshire y,
después de que su familia se mudara a
Lansingburgh, Nueva York, en 1826, se
convirtió en ebanista a los 18 años. En
1847, se mudó con su esposa e hijo, William H., a Grand Rapids. Tuvo éxito
en los negocios de aserradero y ebanistería. En la década de 1860, construyó
el Canal de energía Hídrica del Lado
Oeste en la fachada del río que había
comprado (figura 6).

Powers es el grupo de estructuras rojas que está a la izquierda. La estructura roja más pequeña, en el extremo oeste del
puente Pearl Street, se convertiría en la fábrica de la Wolverine Chair and Furniture Company, donde, en 1880, William
T. Powers instaló su primera central de energía hidroeléctrica. (Fuente: adaptado de una imagen de alta resolución de
