My submission is for a carbon neutral commercial aircraft propulsion. The propeller aircraft gave way to the jet mainly due to the large speed difference between the two. Propellers became inefficient at higher speeds such as Mach .8 and the available piston engine technology of the 50’s had insufficient power, and were bulky and heavy.
Many types of railings/guard rails are shown beside the hilly road but that cannot always save cars from falling from a hilly road. Many times a car has fallen by crossing or braking the guard. But it is not possible to increase the height of the railing by the present system,
My idea is an emergency parachute for Paragliders(PG) with a variety of electronic sensors and AI based, data processing CPU which is responsible to recognize dangerous situations automatically in the air and additionally a remote controlled trigger for SIV-Courses and PG school trainings.
It has happened that PG Pilots got disoriented,
The concept of an inertial propulsion spacecraft was developed in response to the limitations of propulsion in the form of low- or high-temperature plasma recoil in current rocket propulsion systems. These limitations mean that the rocket can only achieve a speed that does not exceed the speed of the plasma's ejection from the engine nozzle.
From WW II and later, also from its use as rotor tip power in some helicopters, we know Ramjets could have a use in certain applications where fuel economy is not first requirement. German data seized by the UK indicate Lorin Ramjet best arrangement is 10º divergency in the intake/ diffuser section, for a total length of 1559 cm,
The “Comet Towed Ion Propelled Spacecraft” is a concept design for a spacecraft utilizing a combination of modified solar power arrays (for onboard energy production) and ion propulsion thrusters (for thrust and speed), which will utilize the energy provided by the ion tail of a comet passing through the solar system.
PROBLEM:
Few planets and satellites in our solar system can have the right conditions for life to develop (Mars, Europa and Enceladus). The space missions to explore these worlds are very expensive and we've to develop cheaper technological alternatives with satisfactory results.
SOLUTION:
To find possible traces of life in our solar system, we're going to develop sensors,
It is seen at the time of a cyclone that the wave of sea is crossing the guard wall and creating a flood. To prevent a flood from this reason the height of the sea guard wall must be increased. But if we do increase the height of the sea guard wall of bricks or concrete permanently,
Use atmospheric water generator powering by solar cells;
Then use a small nuclear reactor to convert water to steam to power an electric generator;
Re-condense water vapor into water using heat exchangers;
Use the electricity to power two fan duct motosr to push it onwards.
Because high atmosphere clouds contain water,
Introduction/ Inspiration: Laser-induced breakdown spectroscopy (LIBS) uses a high intensity laser pulsed for ns (nanoseconds) to form a plasma and atomize a local point on a material sample. When the laser is discharged it ablates a very small amount of material, in the range of nanograms to picograms,
