Large trucks produce excessive greenhouse gasses due to inefficient reciprocating engines and complicated gearboxes. This hovercraft would be much better because it eliminates friction with the road surface due to flexing tyres and suspension. It can also run on alcohol, a non fossil fuel,
Graphene-based supercapacitors offer several key benefits that make them an attractive option for next-generation energy storage devices.
NASA Langley Research Center has developed multiple ways for amorphous robots to autonomously move across a surface without needing conventional wheels or legs. Amorphous robots are useful in dusty and sandy environments in which greater mobility, passive shape changing, and immunity to dust and contamination are important.
Highly capable small UAVs provide substantial business opportunity, especially if allowed to operate in the suburban market. Reliability issues force the use of a safety pilot for each vehicle in operation,
Enabling computing systems to understand user interactions with everyday surfaces and objects can drive a wide range of applications. However, existing vibration-based sensors (e.g., accelerometers) lack the sensitivity to detect light touch gestures or the bandwidth to recognize activity containing high-frequency components. Conversely,
The observed birds gliding flight performance studies indicate that their aerodynamic drag is lower than expected for their flight regime [1], and the best “sailing” birds (condor, vulture, albatross, etc.), have black feathers, a quite unattractive matting attribute...

In nuclear fusion, two nuclei of light atoms, generally hydrogen and its isotopes (deuterium and tritium), join together to form another heavier nucleus. These reactions can release pollution-free fusion energy. An example of fusion reactions are those that take place in the sun,
Kids with ADHD and autism struggle with focus, learning, and social interactions. This affects their school performance, exposes them to peer judgment, and increases the risk of substance use.Drug and behavioral treatments often fall short due to side effects and costs. Neurofeedback, a proven method,
PROBLEM: One of the problems with beam scaling systems, as well as command systems, is that the surface-to-air missile must have great maneuverability to intercept an evasive target. As they approach a target,
Currently the depletion of fossil fuels, global warming, environmental pollution and greenhouse gas emissions, among other problems that affect our environment, show us the need for a change in the distribution of our energy matrix towards the use of less polluting and renewable energy, that is,
