How seriously to take my post would seem to depend on the veracity of the
Harvard study. If substantiated, then I smell CDR "Business Model". As from my
calcs, while mental performance might be linear with ppm, % performance as
reported won't be. But if it were, a better guess on numbers is: 280 ppm = 0%
effect, 400 ppm = 6% reduction, 1000 ppm (BAU 2100) = 36% reduction, 1400 ppm =
56% reduction.
Anyway, we at CO2-B-Gone Industries will be conducting tests in classrooms with
our Model C decarbonizer adjusted to either 280, 400, or ambient ppm. We'll be
looking for differences in student SAT scores among rooms. Might these results
finally unleash market demand for CDR (at any price)? ;-) ;-)

Hi Olaf and Greg,
There are existing competitors for CO2 absorbtion, with stable markets, with
which CATO might outcompete:
There is rebreathing gear for diving. I believe these use manufactured
CaO-containing mixes.
There are CO2-scrubbing set-ups in military submarines, as well.
There are rebreathers for emergency use by miners, also.
Large offices might supply CO2-scrubbed air as a proven productivity boost.
I expect that large submarine navies have researched and proven the level of
cognitive impairment with CO2 level increase, as another data source.

Hi Greg,I have been trying already for more than 5 years to get support for
cleaning the internal atmosphere of buildings that suffer from the

evidence that high CO2 levels in offices or schools have a negative effect on
our brains, this may be taken more seriously in the future See attachment,

"The team’s results, published in 2012 in Environmental Health Perspectives,
were statistically significant, but they were cautious, noting that
“confirmation of these findings is needed.” That confirmation came last fall,
when a team led by Harvard public health researchers published another study in
the journal, using the same test. They found that participants performed only
half as well under indoor carbon-dioxide concentrations of 1,400 ppm as they
did in a well-ventilated room."
This could explain some things. Assuming that there is zero effect at 280 ppm,
the world population is 5% less mentally capable now at 400 ppm than it was
pre-industrially. At IPCC BAU in the year 2100 the world will be >32% impaired.
Amplified CO2 effects indeed, and all the more reason we need CDR installed in
every room where climate/CO2 decisions and policy are being made. And every
other room in the world. If climate change and ocean acidification aren't
reasons enough, is mental health the killer app and raison d'etre for CDR, of
course pending ethic(ist)s and governance approval? ;-)
