With an Isp of 175 sec with a density Isp of 1.5, it creates a rocket motor 1/2 the size of a normal solid propellant motor. Although low in Isp, this combination has a very high density Isp making it possible to reduce the size of a known total impuilse by ½.
Create a returnable plastics lottery system where reverse vending machines are used as "slot machines" and where any (authorized) plastic item could be deposited and where only very occasionally would the depositor win a (relatively) large dollar amount prize.
Astronauts in weightlessness, inside of a large pressurized habitat, can be self-propelled through the cabin air WITHOUT pushing off against any object. A slipper-like variant of swimfins displaces cabin air to push them forward on their own power (CTF 2023 Holmin).
Prototype has flexible plastic core sheet adhered to rubber soles of strap sandle foot-holders,
As a technology, spark ignition power units feature high degree of maturity. On the other hand, incremental benefits on a wide scale mean significant impact!
Spark anemometry leverages exactly this: increased efficiency for new and existing engines. Improved control margins are obtained through in-cylinder fluid motion data that renders cylinder-to-cylinder optimal ignition adjustment possible.
Every once in a while, a revolutionary product comes along that changes everything.
Wildfires have become an increasingly destructive force, wreaking havoc on communities and natural landscapes worldwide. In response to this escalating crisis, a groundbreaking invention has emerged: a metal spiral wire system designed to prevent the spread of wildfires and protect firefighters on the front lines.
A food container lid that contains a cutlery incorporated into the internal part, the cutlery folds on itself so that when the lid is opened it unfolds reaching the length of the container. In the prototype I made, I designed it for a baby food container, however it can be used in a wide range of products,
In the domain of flight, one of the main supporters of worldwide carbon dioxide discharges, the quest for practical options in contrast to conventional petroleum product controlled airplane has prodded a scope of imaginative ideas and advances. Electric airplane, however encouraging in their capability to decrease emanations, as of now face limits in speed and reach,
Aircraft, one of the biggest carbon dioxide producers worldwide, do not have a viable alternative. Electric aircraft are slow and extremely short range. Hydrogen powered aircraft have a more normal range but require specialized equipment while still remaining slow and expensive. Synthetic aviation biofuels do exist but are significantly more expensive that fossil fuels.
In the realm of aviation, one of the most significant contributors to global carbon dioxide emissions, the pursuit of viable alternatives to traditional fossil fuel-powered aircraft has spurred a range of innovative concepts and technologies. Electric aircraft, though promising in their potential to reduce emissions, currently face limitations in speed and range,
Near-Earth Asteroid (NEA) detection is crucial due to the potential threats and opportunities these celestial bodies present. Identifying and tracking NEAs is vital for planetary defense. While catastrophic asteroid impacts are rare, their severe consequences necessitate early detection. This allows scientists to assess threats and develop strategies for deflection or mitigation, protecting life and property on Earth. Additionally,
