During the last decade, the commercial drone industry has grown exponentially. Even though the hardware has improved significantly during that time, drones are still limited by their battery life of 10-20 minutes. Such limited flight time restricts their use in many applications, such as search and rescue, delivery, and inspection.
The transition to a sustainable energy supply requires efficient, cost-effective and environmentally friendly storage technologies. Water electrolysis and the associated power-to-gas technology for regenerative hydrocarbon generation principally meet these requirements, but have conversion efficiencies that are poor compared to batteries.
The current enclosure of the prototype antenna is somewhat brittle. Replacing the "tube" with Ultra High Molecular Weight Polyethylene would make for a much stronger and more reliable enclosure. According to US Plastics of Lima, Ohio, USA; as long as you use virgin UHMW PE, it is transparent to all EM frequencies.
withINSPIRED is a line of personalized clothing that has inspirational words or phrases printed on the inside of the shirt. This is a little out of the box for this contest, but we thought it was worth entering because inspiration for designs, inventions and dreams can start with a small spark that evolves into a life changing concept.
We are all worried that we are putting too much CO2 into the air and warming the planet. Unfortunately almost all of our waste handling systems concentrate on rotting, burning, and fragmenting a lot of hydrocarbon based products, which will put even more CO2 into the air.
We need to redeploy the human workforce for sustainability.
Current drone flight approval and evaluation is frustrating both for authorities and drone operators as well. Every single flight plan consumes roughly 40 man hours to the authorities and spans within a week or two limiting scalability. In the future where 30,000 flights are expected only above Sofia this process is more than archaic.
The portable oxygen concentrator is a great technology, blessing thousands with the opportunity to remain active and functional with their breathing disease. However, as a user requiring 24/7 oxygen, I can attest that these devices are far from perfect. I have tripped on the oxygen cannula tubing and broken my shoulder.
Introduction:
The present study is based on the growing need to seek alternative water supply sources, taking into account the increase in consumption and the scarcity of drinking water that affects several regions of the world. For this purpose, a portable reverse osmosis desalination model was designed in order to meet the treatment of brackish water.
"Scientists investigate that which already is; engineers create that which has never been. - Albert Einstein.
Einstein relative energy: "When a vehicle is in motion the wind sheer passing by the vehicle can be converted to torque and on to wild AC".
