Abstract: An air infiltration system for a hydroelectric plant includes a spillway gate and a linearized cone valve coupled to the spillway gate, the linearized cone valve having a pivotable plate assembly. The spillway gate may be a tainter or Stoney gate and the pivotable plate assembly may have a deflection plate. A method of infiltrating air in water released from an impoundment may include: lifting a spillway gate from a resting position proximate a bottom of a spillway; and pivoting a deflection plate coupled to the gate proximate the bottom of the spillway; wherein water flows through an opening disposed between the deflection plate and the gate and is sprayed into an atmosphere to be oxygenated.

Abstract: A data center comprises an enclosed space, a support disposed in the enclosed space, a plurality of cryptocurrency miners disposed on the support, and a barrier wall separating the enclosed space into a first portion on a relatively cool side and a second portion on a relatively warm side. The cryptocurrency miners each comprise a miner fan for circulating air from the first portion, and the cryptocurrency miners are each disposed so that air moved by the miner fan is exhausted into the second portion. A method of cooling a data center involves drawing relatively cool air into and through miners. Once the air is warmed inside the miners, the air is exhausted into a partitioned space.
