If I were doing an Edisonian approach to a Rossi Replication, here's my mix:
1 kg of Raney Ni 2 g of Zr per Arata, et.al. Dash of Cobalt 60 Stir well and pressurize with 300 kPa of H2 and have a standby of N2 for quenching. Create a 50 deg C gradient over 0.3 m of the mixture and prepare to remove the heat. Adjust mixture, pressure and gradient until well done. No additional H2 is required until next week.
