Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Farmers’ Capital Expenditures, Who Benefits? [PDF]

open access: yesJournal of the Northeastern Agricultural Economics Council, 1975
Farm employment fell from 12.8 million workers in 1929 to 4.4 million in 1974. One frequent explanation for this drastic drop in employment is the replacement of labor inputs in this sector by cheaper and more productive capital inputs. Assuming the farm labor market was in equilibrium at the start of this substitution process (admittedly a weak ...
