Genetically-engineered viruses may power devices of the future

This has micro-Frankenstein run amok written all over it.

Maybe the viri are using us... :O its all planned

Bacteriophages are viruses only capable of infecting bacteria. The differences between animal cells and bacteria are so great that animal cells cannot become infected by the virus. It's similar to how some viruses that infect humans don't infect cats, and cats and humans are pretty similar--being both animals and mammals. Bacteria and humans, on the other hand, are extremely different organisms.
It's not so much a matter of good or bad virus--they're pretty bad for the bacteria--as it is a matter of a specialized virus.

I think it's wrong to play with this type of microorganism.

what if this genetically-engineered virus powers my vibrating chair but by one fluke of nature mutates, do I get a cold shoulder? do I call a technician? do I call a virologist?

Mutated viruses that could end mankind is only in the movies. Then again so is "Genetically Engineered Virus"

''Unlike some more menacing varieties, this genetically engineered virus is a bacteriophage, or "macrophage". That means the virus in question is benign to all but bacteria -- that's a good thing for more complex organisms like you and me.''
