If you can get 100 watts into a one foot long HF dipole, it will be just
as efficient as a half wave dipole that also has 100 watts into it.

But only on the very narrow band that your lossless matching covers.
If you want the bandwidth of an halfwave dipole you will need
a lot of one foot ones plus a lossless distribution filter.
Very far form "as efficient" IMHO
And on receive the things get worse :-)
