MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. Geologic pumped hydroelectric storage works by pumping water to a reservoir behind a dam when electricity demand is low. Earlier post.).

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and.

ARPA-E to award $27M for advanced nuclear reactor systems operational technology: GEMINA

Green Car Congress

The GE Research team aims to reduce operations and maintenance (O&M) costs by moving from a time- to condition-based predictive maintenance framework, using GE Hitachi’s BWRX-300 boiling water reactor as the reference design. Argonne National Laboratory: Maintenance of Advanced Reactor Sensors and Components (MARS) - $2,200,000.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

This project will develop and optimize a novel, engineered microorganism that produces a biodiesel-equivalent fuel from renewable hydrogen and carbon dioxide, at costs of less than $2.50 Water will be the primary byproduct. A novel metal complex for electrolysis of water will be used to generate the hydrogen at high rates.

Even his inaugural paper was forced to acknowledge the voracious appetite of neural networks for computational power, bemoaning that "as the number of connections in the network increases.the burden on a conventional digital computer soon becomes excessive.". But Rosenblatt's ambitions outpaced the capabilities of his era—and he knew it.

A single torus wheel is made of an elastic elongated coil spring in which the two ends of the coil connected each other and is driven by a piezoelectric actuator (stator) that can generate 2-degrees-of-freedom (axial and angular) motions. We propose a palm-sized omnidirectional mobile robot with two torus wheels. Paper ] Thanks, Ayato!
