Over the past decade, the airline industry has undergone significant change. As fuel and energy prices have soared, airlines have scaled back on routes, merged with and acquired other airlines, and shifted regional traffic to key hubs to reduce operating costs and remain competitive.

Particularly in the United States, where several airlines failing to adapt have declared bankruptcy and ceased service, this has caused a significant reduction in the number of airlines and has also reduced the number of major of airline hubs connecting regional routes. These factors are contributing to an increase in hub airport congestion and increased ticket prices, which pose a serious problem to transportation. Although low-cost carriers can keep costs competitive at airports serving more than one million passengers annually, regional airports served only by legacy carriers are vulnerable to future increases in ticket prices. This, coupled with a lack of alternative high-speed mass transit, will leave

My idea is an electric car that has a new type of powertrain that does not rely on solely on recharging the batteries every time the power depletes. By using wind energy, this car will hardly run out of power and will be driver and passenger conscious being made out of better materials rather performance focused made out of flimsy materials, making the occupants of the car safer.
The car will also have the ability of being fast with a special new type of drive layout and assembly.
Last but not least, this car will the capability of flight, it will be the first realistic car that has this option.
Not just an odd sort-of car, it will be a real car that looks just like any other automobile and performs like any other automobile with real flying ability.

A lighter-than-air hybrid airship that can haul truckload freight using buoyancy cells filled with hot air rather than helium or hydrogen.  The hot air is produced by a pair of small turbojet (Brayton cycle) engines via a set of heat exchangers that can be regulated to meet temperature targets for equilibrium altitude for buoyancy/trim cells and outer envelope, and a pressure target for inflation, ballast, trim, maneuvering and propulsion.  The outer envelope is maintained at a much lower temperature and pressure for additional lift and streamlining at any given velocity.  The airship uses vectored thrust for propulsion and close maneuvering.  In forward flight at a velocity sufficient to establish laminar flow, attitude is controlled by two sets of retractable quad-canard wings, one set forward and the other set aft.  When fully extended, these canard wings, are powered by a pair of Stirling cycle engines that stroke to propel and steer the aircraft in flight.  Since the canards do no

Let's push for our smartphones to be even smarter

This can be achieved by the standardization of 5.9 GHz capability in future smartphones by manufacturers.

The 5.9 GHz band has 75 channels called the Dedicated Short Range Communications (DSRC), specifically designed for automotive use.

Currently in Europe and Japan, DSRC is used for toll collection systems. E-Z pass, the largest most successful toll payment program worldwide, uses transponders that cost about $2 dollars to manufacture.  Compared to a $20 5.9 GHz transponder, distributed to over 13 million accountholders, the agency can save over $260 million dollars. This can be achieved when smartphones are interoperable with current toll collection systems in the United States.

With this DSRC technology built into our smartphones, we will not only have a new toll payment availability, many transportation services will be innovated.  
 
Electronic parking payment is another DSRC service that can be provided with the

As students of the iSchool at Drexel University in Philadelphia, a major city with numerous highways going in and out of it - it is obvious that traffic jams at major highway intersections are a growing occurrence known to many in the developed world. Rush hour adds to this fiasco and causes traffic to come to a standstill. These problems could be avoided if the roads leading up to, and at the intersections were smart enough to adapt to the changing flow of traffic.

 

By the design standards of today, major highway intersections consist of overpasses, roads, and ramps that circumvent, intersect and run parallel to each other to allow traffic to flow into each other and allow drivers to navigate to different locations. This however is not enough - as with increasing traffic, the flow of the traffic is choked and causes major delays for drivers.

 

One of the causes of this is that the roads and overpasses are static, and can only guide traffic in their predisposed design. If, however, the

Trains have being an efficient method of personal transportation for a very long period of time with its capability of being able to travel long distances with comfort and safety. However, though out the world, the need of trains that can travel in extreme velocity become clear. With the trains traveling faster, the costumer benefits in terms of travel equality and the rail computer benefits in terms of profit. From what it seems, Maglev is the perfect solution for the high speed trains, which can reach almost 600km/h. However, the railing cost of Maglev is too expensive, resulting that there is only two operational Maglev line within the entire world. Clearly, this is not the solution.

 

“The flying train” is an attempt to produce a relatively lower costing (compeer with Maglev) short train that is dedicated for personal transport. The essential idea is to insert a propeller powered by a powerful engine on each carriage and inserting wings on each carriage. The train doesn't use the no

The idea involves of a low-power wireless sensing device (node) that is commercially available, to which multiple analog or differential sensors or probes (also commercially off-the-shelf available) can be connected for wireless data acquisition. Multiple nodes that can form a wireless network can be powered by energy harvesting devices installed in roadways (e.g., highways, streets, etc). The harvesting devices containing piezoelectric materials will convert the kinetic energy from moving vehicles (i.e., load/compression from vehicles' wheels) into electricity, through the compressed piezoelectric materials. Thus, modulated voltage/current from the squeezed units in the roadway will supply power to the nodes/network continuously. Hence, a smart (wireless) health monitoring system is created that could assess various real-time damage conditions on numerous civil, mechanical, etc. infrastructures.

Considering EV to be the cleanest source of transportation in city conditions, they seem to be the future of cars.

The main problem that they suffer is of short battery charge, limited to about 200 miles. And for charging them back, they have to be plugged to electric supply at base stations which causes time wastage and irritation to the users since they have to lave the comfort of their car and stand waiting to get charged. Also it limits the car's range and use for long distance city travelers.


I have proposed a solution to the problem by way of ON THE GO CHARGING GRID similar to those used in bunker cars commonly seen in entertainment parks.

US airlines’ collective traffic will grow by 3.2% a year over the next two decades, the Federal Aviation Administration (FAA) predicted in 2011. Continuously rising demand in the air transportation system, especially at airports, is one of the major factors contribute toward heavy traffic congestion. Air traffic congestion especially at a taxi way not only creates emissions such as NO2 and CO2, but also wastes huge amounts of fuel. Therefore, the U.S. and other countries’ governments have been working on finding a system-wide approach for intelligent air traffic control systems at airports.

 

When airports are in the construction or redesign process, we can build a towing system on the ground that allows airplanes to be pulled out of gates and be towed to runways automatically. The towing system here is one of the conveyor systems that transport airplanes onto paths that are predetermined at an airport. The towing system will be controlled by a super computer which allows for more e

I want to create an autonomous marine vessel/ship that will be able to sail without a crew.

One of the most controversial topics in the field of technological innovation is the concept of machine autonomy. Scientists and engineers around the world have been working persistently to create an autonomous vehicle. The research in autonomous vehicles has been almost entirely focused on cars and helicopters. However, given the nature of the environment/terrain where these vehicles operate, it has been extremely difficult, and, thus, progress has been made at a slow pace.

On the other hand, progress was made at a faster pace in creating an autonomous catamaran. One of the most interesting research papers I came across is a paper about the autonomous catamaran built by PhD Gabriel Elkaim.  The autonomous catamaran, Atlantis, was built based on a modified Prindle-19 day-sailing catamaran. It used GPS and accelerometers to find its position and direction, several sensors and actuators to character
