In natural language and in cognitive decision-making, alternative is one of several things/(abstract or real objects)/actions which can be chosen. From a specific perspective/(point of view)/goal, alternatives are always equivalent.
In logic and mathematics, alternative is the element of logical disjunction.
In different contexts alternative (or Alternativism) may refer to :

An Alternative Fusion Development Pathway - Georgia Institute of Technology paper proposing developing fusion first for uses other than electricity.
Cold Fusion and the Bible Code - The King James English bible code mentions cold fusion energy.
Feasibility of a Colliding Beam Fusion Reactor - Debate and calculations on Colliding Beam Fusion.
Modulated Quantum Neutron Fusion - The site discusses a neutron fusion concept based on conversion of hydrogen into neutrons, which then react to form helium with the release of fusion energy. The details as well as related theories and publications are presented. Developed proton:electron:proton nuclear model derives specific values for 60 unexplained phenomena to within 1% of their empirical values.
Meta Description: [ By solving Einstein's Unitary Field Theory, W. T. Gray has been able to mathematically link relativity to quantum mechanics using a classical physics analysis from the perspective of the electron. ]
Muonic Hydrogen Fusion - Research attempting to understand the reactions involving muons and different isotopes of hydrogen, as well as muon catalyzed fusion.
Paper on Colliding Beam Fusion Reactor - Paper proposing fusion reactors using proton/boron-11 colliding beams confined in a field-reversed configuration.
