Can water be pumped through carbon nanotubes? If so, has anyone tried? If they have, has anyone tried running an electric current through a water-filled nanotube? How about a magnetic current? How about light? How about sound?
Can carbon nanotubes be used as an antenna? If they can be filled with water, could they then be used more effectively as an antenna?

You can definitely cram water into carbon nanotubes, but they’re hydrophobic, so it’s not easy.
You can run an electric current through carbon nanotubes whether they’ve got water in them or not.
Spin transport is possible in perfect carbon nanotubes (magnetic current).
Carbon nanotubes are strong antennas, so they strongly interact with light. However, they are way way way too small to be waveguides for optical wavelengths, and EM radiation with an appropriate wavelength is way way way too penetrating. Water within them would just cause more scattering, not help carry current. Water carries ionic currents, which are orders of magnitude slower than electron or hole currents in nanotubes.
You can definitely carry sound with carbon nanotubes—google ‘nanotube radio’.
