Papers discussing artificial ocean cooling to weaken tropical cyclones are published. Cooling sea surface temperatures by 2.5ºC would weaken and reduce the damage of a tropical cyclone but lack a practical method. This is a cost and logistic capable autonomous solution.
The ocean thermocline provides a source of cold water. Storm waves provide energy.
3D printing’s the potential to drive mass customization, reduce waste,
Our product is a next-generation, biodegradable, drug-eluting ureteral stent designed to address critical challenges in urological care. Current stents, typically made from non-degradable materials, are associated with complications such as encrustation, biofilm formation, and urinary tract infections (affecting 5–10% of patients), as well as the need for secondary surgical removal,
Superconductivity, a quantum phenomenon allowing electrical current to flow with zero resistance, is traditionally achievable only at cryogenic temperatures. At its core lies the formation of Cooper pairs—bound pairs of electrons mediated by phonon-electron interactions. This proposal explores a novel concept: utilizing precisely tuned photons (light) to modulate phonon dynamics,
First impressions of the Messerschmitt bubble car might be that it is an inferior vehicle, but read what Wikipedia has to say about it. Designed by Fritz Fend, a designer of fighter aircraft, it broke all records for a small engine vehicle on the Hockenheimring. A modern version would be bigger to accommodate better seats .

RESULTED QUADRATURE REQUIREMENT FOR THE QUANTIZED VALUE OF CIRCLE CIRCUMFERENCE TO DIAMETER RATIO: 4/ SQRT{[SQRT(5) +1]/2]} [ SHIFTED AND SPLITTED RED LINES FROM X-Y ORIGIN POINT (similarly GREEN lines corresponding to another value of perimeter to diameter ratio), IN CONTRAST WITH BLACK LINES.
The challenge:
Renewable fuel based on alcohols, like Methanol, Ethanol and Butanol, show great advantages not only in CO₂ reduction, but also in the engine’s efficiency and its maximum performance. They are however more difficult to vaporize than gasoline, which means difficulties at start up and in general when it is cold.
Traditional ceramics, while offering exceptional hardness and durability, are inherently brittle, limiting their use in applications requiring both flexibility and impact resistance. This study investigates the mechanical performance of soft, multilayered ceramics, focusing on how hexagonal tile size, adhesive interlayer thickness, and layer configuration influence flexural compliance, penetration resistance, and energy absorption.
This improvement of an aerofoil compensates for side winds.
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, which can be produced from corn.
