As Dr. Delbert Blair has said many times is that "Dio's are a gift from the future."
Dio's are different than Orgone in that Dio's transmutate energy while Orgone brings in energy.
We are working on a new structure and until the newest release the Pyramids are a fantastic option.
For a standard single family home, with a basement and 3-4 bedrooms you should have a Pyramid in each bedroom and one in the common living space (living room).
This will bring about the same energy concentration as the one Pyramid from years ago (that cost much more than 4 of the smaller pyramids).
Enjoy!
