More than a half century ago Wilhelm Reich built what he called an "orgone accumulator" to store and concentrate qi or "orgone." This consisted of a container constructed from alternating layers of organic and non-organic materials. Reich used the accumulator to create a device to ameliorate the weather by drawing away sha qi , and he named this device a "cloudbuster." More recently, Don and Carol Croft, adapting an invention of Karl Welz, constructed what is now known as a "CB", an ingenious device which draws in sha qi from its surroundings, transforms it into sheng qi , and sends the sheng qi directly up into the sky above. The advantage of the Crofts’ device is that one does not require a sha qi dump, since the sha qi is not accumulated, but transformed.
In a CB the alternating layers of organic and inorganic material are replaced by a matrix of fiberglass resin (organic) and curved metal (inorganic). What induces the attraction and transformation of sha qi into sheng qi are six quartz crystals at the bottom of six copper pipes. A CB is pictured in the photo below, where the resin-metal matrix and crystals are enclosed the the white bucket:
