Currently there is a need/desire for alternative energy vehicles. One major problem is the cost. The Chevy Volt is selling for about $35,000 and the Nissan Leaf is around the same. Not a bad price for a new vehicle, but my problem is I already own my car. I don't owe anyone, anything. I truly want an electric vehicle, but I don't want the car payment. I have looked into conversion kits and they aren't very good. The engines aren't great, the batteries aren't great and none have a 4 wheel drive capability. So what can I do if I want to keep my car, keep it 4 wheel drive, but make it electric?

I have designed an ...

The design I am submitting is for a 40-passenger commuter aircraft with vertical take off and landing capability. The aircraft is in stable equilibrium during all phases of its flight - during take off, cruising horizontally and landing. Stable equilibrium is achieved by having a single thrust axis. Engines and propellers are mounted between two fuselages; it is this unique geometry that facilitates stable flight characteristics. Disk loading is reduced by using four propellers which have the same disk load as one propeller of twice the diameter. There are two pairs of coaxial counter-rotating propellers. One pair is in front one in the rear. They are driven by two back-to-back turboprop engines. This arrangement cancels gyroscopic effects. Redundancy is ...

A. The background

The 4 stroke Otto engine

Internal combustion gasoline (Otto) engine is an basic prime mover for the passenger automobiles and many other applications. The problem with this engine is its inherently low thermal efficiency in order of 24 - 26%.
The egine works at well known 4 stroke cycle:
1. Intake
2. Compression
3. Expansion (work stroke)
4. Exhaust

B. The entry:

The 5 stroke cycle Otto engine.

The reason for the low thermal efficiency of the Otto cycle is the high content of unused energy in the exhaust gases. One of the ways to recover part of this energy is the use of the turbo-charger. The proposition is to employ as the the energy recovery ...

Helium is very expensive to use in a dirigible and even in a larger balloon or a non-rigged air ship. Some of us even after all this time since the Hindenburg crashed in flames, consider hydrogen as being dangerous. This is a false reason about not using hydrogen. Today, hydrogen with modern technologies, can be safely used in a dirigible or Zeppelins. It has more lift ability and can be economically generated on the base or most any place else. It should be not ruled out because of a 74 year ago event.

When hydrogen is pure like most other inflammables it will not burn because there is no oxygen present to cause flammability. In the confined hydrogen there ...

An electric-plasma thruster utilizing Inertial Electrostatic Confinement (IEC) technology has a potential application as a low-cost, high-efficiency thruster for Earth orbit maneuvering and interplanetary propulsive operations. The basic concept uses ion acceleration along with jet formation of the resulting plasma. It was originally demonstrated at the University of Illinois (U of I) as part of a fusion neutron source initiative at the school. An electrically driven counterpart of the fusion IEC has been conceived of by staff at NPL Associates, working in collaboration with U of I staff.

The IEC thruster uses a spherical configuration (similar to the classic "fusor" device), wherein ions are generated and accelerated towards the center of a spherical vacuum chamber through a spherical electrically-charged ...

We all know the timed traffic signs with big digital screens. But also most of us get bored when we wait until the count down finish to move our car even though the road is already empty and many seconds are wasted for nothing. What about adaptive times that intelligently adjust the countdown values according to traffic density so we can live happily ever after ?

 The idea is very simple but very effective at the same time. Putting a sensor on the traffic sign that counts passing cars from this point and connects to the next traffic sign with another sensor that also counts passing vehicle. Using a very simple equation we can calculate the count of cars ...

This is an adjustable geometry prone recumbent bicycle. The bike is displayed in its "down" position. At low speeds it is "upright", allowing balance by aligning the riders hips over the pedals and the hands over the front wheel. At speeds over 30 mph, the bike will lower down by use of pneumatic gas springs and allow the rider to maintain a more streamlined position for reduced wind resistance. Braking at using the inertia to raise the bike back up to for low speed maneuvering and stopping. This bike does especially well for hill climbing as well due to the ergonomics of leaning into the hill as opposed to be perpendicularly positio9ned to it with current bike geometry.

The new product idea is nicknamed the A-STAR Advanced Superior Tactical Aero Rotorcraft, which has agility control ability via full dimensional thrust vectoring techniques. The A-STAR can be branched from Unmanned Air Vehicle to Manned Vehicle into Safe Air Travel also known as 3 Dimensional Travel. Technologies proposed in this program are to evolve from existing known technologies never before integrated into a full controllable flying vehicle. The proposed propulsion systems start with adaptable engines and the revolutionary Superconductive Electro-Magnetic Propulsion System motors.

Technical Description A-STAR
Mission statement: The Solution Vehicles Co. is to produce the A-STAR Leading edge Aerocraft Vehicles poised for tomorrows needs in Military & Civilian applications with safe, efficient & agile technologies combined for ...

On a typical aircraft wing, a surface that rises from the top surface to help with laminar flow, and depending on the speed, it may eliminate or reduce the sonic boom by creating a secondary shock wave that would cancel out the primary shock wave before it reaches the ground. This would be on each wing top, and a computer would have to control this, so that the correction can keep up with changes in altitude and speed.

My thinking on this is that the secondary wave might be out of phase with the primary shock wave at altitude, and as the waves propagated towards Earth, they would intersect and cancel out. Kind of the same way an audio ...

In the classical movie/TV shot of an aircraft touching down, tires meet the payment with a load squeal and a puff of smoke as they spin-up. Annual commercial flights in the United States are approaching 10M (Research and Innovative Technology Administration (RITA) • U.S. Department of Transportation (US DOT) yielding more than 27,000 commercial landings per day in the United States alone. The proposed design reduces spin-up wear and the associated replacement frequency, resulting in a twofold cost savings. Reducing spin-up wear would allow a greater number of takeoff/landing cycles per tire, reducing material cost for the aircraft owner. Indirectly a reduced maintenance frequency can also allow greater coordination of scheduled “out of service” time for the aircraft operators.
