I see what you are saying, if you can't find it, why do we care?

Two reasons, as the article states, it has been found, twice in fact. Once in Hawaii and now in Iceland. The Icelandic team is drilling another hole near the existing hole to investigate further. Maybe the same can be done in Hawaii.

The other reason we care is that perhaps technology doesn't exist yet to easily find these near surface reservoirs, but maybe it will in the future. If they determine this hole can be utilized, it will drive research into finding these reservoirs.
