CubeSats, Airplanes Made of Batteries?

Dean Sigler Batteries, Sustainable Aviation 0 Comments

Dr. Luke Roberson, Dr. Ryan Karkkainen, and Dr. Xiangyang Zhou are now collaborating on “Creating a structural battery material [that] could revolutionize the way NASA operates small payloads.”  Batteries now take up 20 to 35 percent of the volume in some CubeSats, 10 centimeters (3.97 inches) ×10 cm. × 11.35 cm (4.47 inches) cubes, as the name implies.  Each CubeSat can weight up to 1.33 kilograms (2.93 pounds). Normally made of aluminum, CubeSats carry batteries for communication, storing energy collected from solar cells on their host vehicles, or powering sensors, cameras, and providing environmental norms for science experiments they carry.  Obviously, their small size dictates using every square centimeter wisely.  Replacing their inert walls with a structural battery could free …

Cella Packages Hydrogen in Usable Ways

Dean Sigler Diesel Powerplants, Electric Powerplants, Sustainable Aviation 0 Comments

Cella Energy, a UK-based energy company, announced big plans for hydrogen storage in early 2011, and is now beginning to deliver on its earlier promise. Hydrogen, as desirable as it is for use in transportation, presents many hurdles in its use.  Creating an infrastructure for its distribution has been a major impediment so far, but Cella hopes to overcome that with its nanotechnology pellets that can be distributed, transported and used much like fossil-fuel liquids. Cella highlights the fact that the hydrogen is stored in low-pressure form at ambient temperatures and can be handled safely in the open air (something that can’t be said about gasoline, for instance).  It benefits customers by being able to use existing distribution networks and …
