The Wall Grill

In the morning in my dream, I saw my mother cooking small fish fillet on an iron. She was holding the fillet from the extending skin of the fish and pushing the fillet on the iron with her thumb.  With this method she lightly cooked both sides of the small fillet that could be placed on a sushi. Then I woke up and thought about my dream and turned it into a product, The Wall Grill.

Lately, houses are becoming smaller in big cities. As a result, the kitchens are diminishing. How about using the wall of the kitchen as a cooking surface. A slightly angled stainless steel grill surface attached to the wall. The food to be cooked would be attached to the pegs on top of the grill. It would have separate heater sections controlled by thermostatic knobs. At the bottom of the grill there would be fat collection tray that can be removed and cleaned in a dish washer. A section of the grill would house holes for steam release like in a classic iron. This would allow steam, grilled cooking.

There would also be an external grilling iron. It would be a modified iron optimized for cooking food. You would press it on the food to cook it and steam it on demand.

Underwater Pipe Organ

While listening to Xaver Varnus playing Bach’s Toccata & Fugue in The Berliner Dom, I dreamed of an underwater pipe organ fed by the gas from an underwater chimney. I got my inspiration from Captain Nemo’s organ inside the Nautilus.

Pipe organ would be played by an underwater robot. How would it sound or would it sound at all I don’t know. The whales and the dolphins would most likely hear it. Imagine them gathering around the pipe organ like inside a giant cathedral.

Here is the Music played on surface 😊

Snooker League

I like watching snooker, but seeing so many problems in the organization made me think of new ideas. Organizing open tournaments with so many players is not something I support. This is a problem of Tennis as well. I am in favor of grouping players into leagues. I propose three leagues for Snooker. The top 32 players in the 2 years list will play in a Premier League, like in Football, for a year. The next 64 will play in League 1 and the remaining will play in the Amateur League.

Premier League will have tournaments with high frame count. The players will earn points according to the frames they win. As a result, a player loosing at the decider will get much more points than the one white washed. The games won on quarter finals and beyond will award extra points. All games will be played out of 15 red balls. There will be no Shoot-Out. Each frame won will award 15 points to the player. The tournament price money will be independently determined from the points. Every tournament will award points unlike the current Masters.

League 1 will have tournaments with lower frame count. The players will earn points according to the frames they win. In addition to the classical snooker, there will be 6-10 red ball tournaments as well as multiple Shoot-Outs. Frames won on 6-10 red ball and Shoot-Out will award 10 points. Amateur League will also have similar tournaments.

The objective is to make all leagues attractive to the audience and award the players fairly.

Missile Concept

I thought of a type of missile to be used on stealth fighter planes. These planes have enclosed bomber bays. Therefore, the protrusions would limit the number of missiles that can be deployed for each mission. The missile concept I propose would utilize a ramjet instead of the most common solid rocket engines. There will be no protruding air intake, instead the air will enter the engine by Coandă effect. The missile will have gimbled nozzle for thrust vectoring. As a result, there will be no fins or wings for flight stabilization, but thrust vectoring.

The missile will consume the same fuel as the fighter jet to simplify the logistics. Higher efficiency of the ramjet compared to solid fuel rockets will increase its range for the same mass or reduce its weight for the same range.

Fighter Jet Concept

I would like to propose a family of dual-purpose (piloted and drone) fighter jet. It will be based around commercial turbofan engines. The bigger variant will be designed around a Rolls-Royce Trent XWB-97 engine and the smaller variant will be based around CFM International LEAP. The fuselage of the plane will not exceed the diameter of the engine. High bypass turbofan engines have a large fan in the front and narrow cross section at the back. Therefore, a tubular fuselage will allow space for fuel tank and bomb bays. Both engines I propose generate enough thrust to allow Vertical Takeoff and Landing. Much better fuel economy of a commercial engine allows longer range with less fuel.

The rear of the plane will house an afterburner for thrust boost on demand and gimbled nozzle for thrust vectoring. There will be an optional pilot bay as well. The pilot will lay down inside the bay. During takeoff and landing pilot would be in vertical position. In case of emergency, the bay will be released from the plane to save pilot’s life. Laying down position will be advantageous on high G maneuvers due to better blood circulation and less strain on the spine. The plane will also be operatable in drone mode without a pilot bay.

The plane will takeoff and land on three anchor points, one on its vertical stabilizer and the rest on each wing. VTOL operation will allow almost any ship to be an aircraft carrier and increase the launch sites outside the airports. Use of commercial engines will lower the cost of the planes and their operational cost, as well as improve their reliability.

Top-Down Rocket Design

Space exploration requires mission optimized rocket designs. A design approach that was successful for LEO missions would not necessarily be successful on high energy missions. I am referring to the two staged reusable rockets of SpaceX and similar companies. Ariane 6 has a much better approach especially for high energy missions. I would like to propose a new approach. It is a top-down designed rocket. A rocket design that would allow five or more stages. Depending on the mission, the number of stages would be chosen. For LEO satellite missions, two stages would be enough. For ISS module deployment like LEO missions three or even more stages would be utilized. For the moon four stages and for Mars, six or even more. Instead of strapping boosters around the main rocket like in Ariane design, the additional stages would be attached to the bottom of the previous one depending on the mission requirements.

This design approach would require unified propellent on all stages of the rocket. Additionally, the engines should have modular nozzles to allow easy swapping of them for optimal ambient pressure. The large rocket engine design I proposed earlier would allow this.

Ambitious space dreams require larger single use rockets. Reusability is only practical to the very first stage of any rocket and not for the upper stages.

A Large Rocket Engine

I had previously proposed rocket engines, this one is a scalable engine optimized for cryogenic propellant, liquid methane and oxygen. These propellants require pre heating for a sustainable combustion. Like in SpaceX Raptor engine, the propellant would be pe burned in order to heat them before combustion. My design puts the pre burner inside the combustion chamber. The objective is to transfer the heat inside the chamber more effectively to the propellent. This design negates the regenerative cooling channels outside the combustion chamber and the rocket nozzle. Allowing much larger combustion chambers than the current rocket engines. The problem with large combustion chambers is that the combustion efficiency decreases with the increase volume. I solve this problem with heat exchanger fins around the pre-burner. When the propellant is heated to auto ignition temperature they burn on contact. Therefore, increased heated surface inside the chamber increases the heat transfer between the gas molecules and the hot metal surface.

The pre burner, the combustion chamber and the nozzle of the engine will be made of Tungsten which has a very high melting point and still a good conductor of heat. There will be no regenerative cooling on the combustion chamber. Therefore, the internal temperature will be kept considerably below the melting point of Tungsten by pumping adequate propellant inside the chamber.

Removal of propellant pipes around the combustion chamber lowers the cost of manufacturing large combustion chambers and reduces the heat stress on the shell of the chamber. Removal of propellant pipes around the nozzle lowers the cost of manufacturing the rocket nozzle and simplifies the gimble mechanism.
