A team including Shmuel Nussinov of Tel Aviv University in Israel says the OPERA report that neutrinos faster than light also violates the principle of the conservation of energy.

The energy available to faster-than-light neutrinos from the CERN source (pions) is too small by a factor of 10 to explain the speeds reported, they said.
