Abstract: Systems, computer program products, and methods are described herein for adaptive user-locality-based data transmissions. Embodiments of the present disclosure are configured to generate a first dataset including one or more first data entries associated with a user, process the one or more first data entries of the first dataset, extract, via the processing, one or more geographical data entries of the one or more first data entries, receive, using a network interface, a second dataset including one or more event data entries associated with the one or more geographical data entries, generate a data transmission including data of at least one event data entry of the one or more event data entries, and transmit, using the network interface, the data transmission to a user device of the user via a communication network.

Abstract: A receiver for converting solar energy to heat a gas to temperatures from 700.degree.-900.degree. C. The receiver is formed to minimize impingement of radiation on the walls and to provide maximum heating at and near the entry of the gas exit. Also, the receiver is formed to provide controlled movement of the gas to be heated to minimize wall temperatures. The receiver is designed for use with gas containing fine heat absorbing particles, such as carbon particles.
