While Jones Beene's birds and Bill Beaty's bees are interacting with the aether. :-)
I propose using very large cylinders of solid CO2 with the ends pointed toward the sun
so that the 1.3 kilowatts/meter^2 solar insolation (at earth's distance) can provide
the 200Kj/kg heat of sublimation, thus providing a "sublime" thrust as the CO2 comes off.
Heat from a Cold Fusion radiator can be used when the '"Outer Limits" of solar energy
is attained.
Helps alleviate the green-house gas problem too.
