NASA Lewis H2-O2 MHD program [PDF]
Performance and power costs of H2-O2 combustion powered steam-MHD central power systems are estimated. Hydrogen gas is assumed to be transmitted by pipe from a remote coal gasifier into the city and converted to electricity in a steam MHD plant having an

Advanced Science, EarlyView.A yolk@shell structured photothermal evaporator was prepared via simple sol‐gel and spray coating methods. By taking advantage of the unique yolk@shell structure, the position of the TE module within the evaporator can be optimized without affects its water evaporation performance. This results in efficient and stable evaporation (3.08‐3.17 kg m−2 h−1)‐
