Transportation - 2012
México, Distrito federal
As we know, bikes have been an important form of transportation used by civilization for centuries and have helped in moving their users in a lighter and faster way to their destinations. They are seen today as one of the best solutions to the problems of transport and transit in cities, and as a way of taking care of the planet.
Hence arises the idea of the Dr. J Tricycle project that merges the benefits of cycling, and three important elements of today: protection, multi-functionality and style.
Taking Care. Due to population growth, the use of large transport is ...
A full-time four-wheel-drive system for a motor vehicle is big, heavy, expensive, and inefficient. It requires a clutch, transmission, three differentials, two drive shafts, and four axles. The transmission contains dozens of moving parts, and each differential includes another half dozen. To get to the wheels, the power must go through the clutch, transmission, and two differentials. Assuming that each unit is 80% efficient, the efficiency of the series is 80% x 80% x 80%, which equals 51.2%. Almost half the power is wasted.
I propose a smaller, lighter, cheaper, and more efficient seven-speed hydrostatic drive that requires only ...

As we know, when we start the engine, power from the engine is transmitted through a fly wheel clutch, drive shaft, gear box, final drive, rear axle and finally reaches the rear wheels to drive our vehicle. We need different speeds for different applications, for that we have provided a gear box but when we engage the gear there is always a clashing noise in off-road vehicles (like tractors, earth-movers, etc.) which is quite unpleasant for the user.
The actual reason for the clashing of gears is that whenever we press the clutch pedal, the driving shaft gets disengaged ...
The ElectraCopter is a single-seat ultralight electric helicopter. At 150 lbs empty with batteries, it will fit into the 254 lb limit USA ultralight category for unlicensed aircraft. It can be potentially used in other categories and in other countries, depending on regulations and design criteria.
A mockup prototype of helicopter and motor has been built to verify weight is within 6% of projected figures. (Photo)
• This design idea updates 60 year old technology through simplification of design and hence, reduction of parts (KISS). Due to the semi-rigid rotor design, it also greatly reduces the time required to ...
TRANSPORTING without ACCIDENTS or ENERGY for a few percent of today’s cost is not a structural, technological, or financial problem. Something that could have been crudely achieved without most in the late 1800’s in the ability to produce a 15’ dia. pipe which can smoothly accommodate the transition of vehicles and containers utilizing rails and electric motors. Without nearly all in the 1940’s. And in today’s abilities, not consuming but cleanly generating energy.
An event whose beginning, incremental, and increasing accomplishments will profitably occupy the idled work force and return that lost economy in an unprecedented efficiency of ...
To control an aircraft, the wing always has certain movable surfaces. All movable surfaces are at down stream because if you install a flap pointing forward, it will create instability and be damaged unless the mechanism is really strong (which will increase the weight significantly).
Can we turn the bad instability to good use? Instability means positive feedback/amplification. That is, to amplify a tiny disturbance into large destructive(or constructive?) force. In other words, it might be able to amplify small control force into real control.
My proposed wing shape is symmetric so it will not create any lift by ...
" A floating marina."
"Three yachts clubbed into one."
Albatross yacht is a 200m mega yacht that also features two skimmer yachts that are always ready to sail independently. This concept yacht takes privacy and functionality to a higher level, you can separate any party or a meeting to different yacht and then rejoin all of them into one big social event. When Albatross yacht is fully connected, it provides passengers with 200m + 80m + 80m open space, even with the mothership alone, it is one of luxurious sail yachts a billionaire can have.
The idea for Project ...
This entry is a concept for a high-speed rail network that would be integrated into the automobile-based infrastructure of the United States. High-speed rail has already proven to be a convenient, fast, safe and efficient form of transportation elsewhere in the world but despite its benefits the idea has never caught on here. A possible way to make high-speed trains more effective in the United-States could be through the integration of personal vehicles. Regions that have developed HS networks such as Europe have denser urban centers and extensive public transportation systems that increase the level of access to HS. ...
The concept of this system is an overhead lightweight magnetic levitated train capable of high speed in any type of weather, including icy conditions. It would be constructed with airframe technology to keep it strong but lightweight.
Its design is for intercity service, its market has a strong world wide potential. The high speed meglev system will use existing highway and rail right-of-ways to keep costs down. Being an elevated dedicated system it would not have to compete with the slower ground level transportation systems by speeding along above them. It would be impervious to most weather conditions.

The T.W.I.N.S. (Trans-Web Infrastructure Network System) Projects (www.aquaterraplanetaryholdings.com) propose to create a single-standard national and international infrastructure and transportation network system consisting of Terra (Land-based) and Aqua (Ocean-based) Bypass Stations that are to be interconnected by a single-standard transport Operating System (OS).
The transport system is sub-surface via tunneling technology, and composed of a network of tube-links within which two sets of transport tubes, one for passengers and the other larger diameter tubes for cargo. These transport tubes provide the airless arena being one of the two elements required to achieve high speed (350-4,000+ mph) travel by capsules / ...
