There are some bacground information on the impact of decline of fossil fuels
to fuel economies in transport powered by electricity. EC view is global oil
production goes into terminal decline within the next two years, from
geoengineering point of view these background considerations may be
Apologies if this has already been discussed, but thought some quotes
in here were pretty precious. Article written in a curious mixture of
tenses. Anyone go to this?
The bigger the scale of the approach, the riskier it is for the
environment, [=small scale solutions to a big scale problem
After a couple of days all the Special K sank. I think this is rather neat.
It gives you a couple of days to whiten and insulate the ocean - just long
enough to mess up a hurricane. Then it can either end up as food for
bottom-feeders or it will sequester the carbon.
I think it could be worth a
Remember, that crashing waves might well be an important factor to consider
in lifetime of the floating material. The approach has to limit evaporation,
not so much heat transfer, and it is a bit hard to see how one would cover
the waves in any sort of continuous way without a much larger amount
does anyone out there see heat harvesting from parking lots as
transformational?

I guess this makes you a cereal killer. Cereal is also relatively expensive.
Starch based packing peanuts would be whiter and also biodegradable, but the
scale and other issues previously discussed in my opinion make this an
infeasible pre-emptive measure.
You may have seen on the weather
There are a variety of artificial materials that could be used, such as corn
starch plastic strips, etc. as well as packing peanuts.
There are lots of agricultural wastes that would be worth a go. Wheat
straw, peanut shells, apple cores, potato peelings, etc.
The logic for this approach is just
I don't as it would have very limited applicability if any at all. Plus, if
the surfaces are eventually whitened as is the goal of the LBNL initiative,
that would reduce the effectiveness of such systems. I also doubt that
sufficient energy can be captured to make it worthwhile, although the
Perhaps you should estimate the cost first. How much straw per ha do you need
to insulate enough to get 50% reduction in heat flux? Or to cover, to make it
simpler. The sea area to be covered would be something on the order of the
area of a hurricane. Purchase and shipping costs for the
