Looks too good to be true, but if it's not it may well be a solution.
The performance metrics of the fuel seem realistic enough, it's the claim they can cost effectively recycle the waste into new fuel which has the hallmarks of a scam (or inventor self delusion, maybe he's so proud of his slight tweak of hydrogen reclamation technique that he just considers the recycling something he can solve with a bit more money). No papers, no patents, no pilot plant, no nothing.
From Wikipedia quoting MacDonald :
"Sodium metaborate might be hydrogenated back into sodium borohydride fuel by several different techniques, some of which might theoretically require nothing more than water and electricity or heat. However, these techniques are still in active development. As of June 30, 2010, many patents claiming to effectively achieve the conversion of sodium metaborate to sodium borohydride have been investigated but none have been confirmed"
Extraordinary claims, zero evidence.
PS. found
a patent at least for the recycling process.
PPS. as far as I can see it's all hand waving. He says "The synthesis process requires the input of energy. Dependent on the actual partial processes involved in the synthesis processes, the energy, for instance, may be required as pressure and/or heat to raise the temperature of the reactants or may be inputted in an electrolysis process." ... the actual partial processes and the way energy is added I can't seem to find.
