Rainwater collected in San Francisco December 3, 2017, tested positive for three metals proposed to be sprayed by geoengineer David Keith.
NELAP certified laboratory McCampbell Analytical found barium at 9.6μg/L, iron at 19μg/L and titanium at 0.38μg/L. Aluminum was below method detection limits. This result is an order of magnitide less than others I have found – at the same source, with the same methods and the same variables.
(These tests cost money – please consider helping cover my costs.)
In his 2010 paper, “Photophoretic levitation of engineered aerosols for geoengineering,” Keith (@DKeithClimate) proposes spraying us with engineered nano-discs made of aluminum, barium, titanium and iron.
Here’s a diagram of Dr. Keith’s toxic nano-discs:
And here he is avoiding questions of aluminum toxicity:
