NASA-Funded Research Converts Waste Heat to Electricity

Scientists have long attempted to convert the enormous amounts of waste heat generated by power plants, data centers, and cars into electricity via thermoelectric power generators (TEPGs). Scientists know how to convert waste heat into electricity. The problem is how to do so in an efficient manner using a material that justifies the cost of the conversion process.

Video Wall Improves Collaboration

The renovated Payload Operations Integration Center, part of the Huntsville, AL-based Marshall Space Flight Center, features a new video wall. The wall includes a 2 × 12 array of monitors that uses RGB Spectrum’s OmniWall 32 Display Processor to route and display up to 32 input signals. The processor expands the ability of operators to share information in real time, such as live video feeds, diagrams, photographs, results of experiments, and information on power usage.

Solar Sail Will Demonstrate “Propellant-less Propulsion”

The Sunjammer Mission team — including NASA, lead contractor L’Garde, Space Services Holdings (SSHI), and Micro Aerospace Solutions — is preparing to launch Sunjammer, the largest solar sail ever deployed, named in honor of legendary science fiction author Sir Arthur C. Clarke. In a 1963 novella, Clarke christened a solar sailing ship “Sunjammer,” powered only by the pressure created by photons from the Sun.
