NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...
National Presto Industries is a company founded in 1905 in Eau Claire, Wisconsin. [2] Originally called "Northwestern Steel and Iron Works" the company changed its name to the "National Pressure Cooker Company" in 1929 and then National Presto Industries, Inc. 1953. [ 3 ]
Although gliders with FES have a shorter range (70–100 km) [2] under power than gliders with two-stroke gasoline sustainer engines (10 litres at 8.5 L/h at 100 km/h = 120 km) [3] or jet sustaining engines (150–200 km), [4] the electric motor can be expected to start reliably provided there is sufficient energy in the batteries.
Presto (including PrestoDB, and PrestoSQL which was re-branded to Trino) is a distributed query engine for big data using the SQL query language. Its architecture allows users to query data sources such as Hadoop , Cassandra , Kafka , AWS S3 , Alluxio , MySQL , MongoDB and Teradata , [ 1 ] and allows use of multiple data sources within a query.

The M6 Presto-Matic was a Chrysler Corporation semi-automatic transmission produced from 1946 to 1953. It was a special manual transmission with a fluid coupling . Although it had just two forward gears, an electric overdrive unit was attached and useful in either gear for a total of four forward speeds.
