Every time I ride my bike to the morning prayers I get of
of our coastal towns, and there's a black line in the air just
above them and all along the coast. On Saturday (the
Sabbath day) it gets a little thinner, and after rainy winter
days, the thin blue line which is the sea
can be observed.
Once a year on Yom Kippur the black line completely
disappears and only the blue sky is seen along with the thin
blue line of the sea.
When I visit Tel Aviv coming down Hamasger St. the bus
and the home of endless engine fixing workshops, I cannot
but notice the plants covered with black soot. They are
from the road, and the walls nearby are much less
This seems to show that plants tend to pull in soot, besides
the known fact that they emit O2 when in the light.
So the proposed idea here is to create tubes from
transparent mesh screen material with plants in them
transparent to light in the daytime and lit by LEDs at night,
their air would flow through them until cleaned and O2
would flow out, cleaning up the city without taking up the
space that vegetation usually does, by attaching them to
light posts and to bare building walls. part of the tube can
made of transparent plastic, so that it looks good, but
doesn't let insects in.
To avoid light polution the led section could be in non-
transparent sections of the tubing.
||Inversion layers are typically a function of geography and climate; LA and Mexico City are typical. There's not much to be done in the way of mitigation other than cutting down emissions.
||However, the problem's self-limiting; eventually, all the inhabitants die, and the pollution goes away.
||a. Can you make one ? Plastic tube or plastic
||b. What is in the black line and Will it kill plants ?
||c. Which plants would work in TA ? generally
||d. Do you really need LEDs? Will your plants want
to sleep ?
||E. Would filters and fans clean more air than
tubed plants ? Assuming the LED were solar
||f. Would the tubes be in the way of bike riders
and pedestrians ?
||G. Don't dead insects add to the soil?
||Don't plants emit O2 only at night?
||No. The oxygen is a byproduct of photosynthesis.
