Nowadays, more people are choosing biking either as an alternative mode to transportation or as an outdoor activity for recreational purpose. The cycling trend was particularly boosted during COVID-19 pandemic as evidenced by the soaring sales in bikes and accessories. Unfortunately,

This is a novel internal combustion engine utilizing a unique multi-link configuration. This solves problems achieving variable compression and extremely long stroke, when combined yields high volumetric efficiency, significantly reduced engine size, higher torque, and fuel efficiency. Benefits include use of lower cost fuels,

INTRODUCING THE TOOL FOR REALIZING THE ETYMOLOGICAL ROOT OF THE MEANING OF “LOGARITHM,” RELATING IT TO DISCRETE GEOMETRY, VIA A CURVE OF A NAUTILUS MODEL [THE NATURAL SUBMARINE] .

“SPIRALOGORITHM” [name coined by Panagiotis Stefanides] Configuration of Photo 1, gives simple relationships between spirals and logarithms.

Sometimes innovation may seem so simple but is truly groundbreaking for the way everyone can now interact with something so familiar and achieve so much more success, more fun than ever before.

This cooler target is to utilize a renewable energy technology that reduce greenhouse gas (GHG) emissions to improving the food, medicine, and vaccine supply chains in Africa. Our product can freeze liquids and maintain the freshness of fruits, vegetables, medicines, and vaccines. It’s powered by solar photovoltaic (PV),

Traditional planar ducted fans can suffer from stall and drag in edgewise flight due to the high angle of attack at which air must turn into the rotors. This creates blade imbalance and instability in the aircraft that rely upon such fixed fan-in-wing designs.

I have invented a Thermoelectric Generator with electrical power of 5,000 watts AC. The generator is the size of a bread box and weight is 15lbs. It is made of bismuth-tellurium P&N semiconductors arranged in a circular or square Thermopile. I researched,

High-Occupancy Vehicle (HOV) Systems

Our design idea solves the problems of cheating in High-Occupancy Vehicle (HOV) carpool lanes. HOV is a traffic management strategy experiencing a large, planned expansion. HOVs are used globally to reduce traffic congestion and promote public transportation use for encouraging ride-sharing.

1.2 million people die every year from traffic accidents. Over 370.000 are motorcycle riders. It is estimated over 150,000 lives could be saved just by promoting a solution that encourages the use of the adequately fastened helmet (worn and firmly fastened),
