The bridge from Spain to Africa

Strait of Gibraltar Bridge: One of the great challenges to the bridge and structural engineering profession is the design and construction of a fixed bridge spanning the Strait of Gibraltar. Several engineers have advanced designs for the Gibraltar Bridge on various alignments and with differing structural configurations but it was Professor T.Y. Lin’s proposal that captured the attention of the world. This design is different. With its 14km length, deep piers, and unprecedented 5000 meter spans Lin’s proposed crossing is innovative but, considering an estimated cost of over 15 Billion dollars and the lack of approval for this nearly 10 year old design, we doubt it will ever be built.

Location: Strait of Gibraltar. Links Spain and Morocco.
Length: 9 miles, Two spans of 4 1/2 miles each
Height: Each tower is 3,000 feet tall. Twice as high as the world's tallest skyscraper. bo319r3194foof
Width: 5 traffic lanes, 2 breakdown lanes in each direction
Road Deck Material: Fiberglass
Length of Wire Cables: 1,000,000 miles (Enough to circle the Earth almost 30 times)
Closest living relative: Akashi bridge in Japan, world's longest suspension bridge at 12,828 feet.
Cost: $15 billion
Dangers: Wind speeds of 80 mph at tops of towers, ship collision, ocean currents, traffic, Sahara Desert dust storms.
Withstand ship collisions and high winds.
A bridge the size and configuration of Gibraltar Bridge is usually protected by artificial islands built around its piers. That way, ships run aground before they can do any damage to the structure.
But artificial islands are not an option in the middle of the ocean. The Gibraltar Bridge designers instead envision a ring of underwater bumpers to withstand ship collisions.
Build in the open ocean.
When determining the exact site of the bridge, designers had to choose between a shallow area that spanned 20 miles, which would have meant many piers in a busy shipping zone, and a narrow portion that's 2,700 feet deep.
But the Gibraltar Bridge designers lucked out.
A closer inspection of the narrow portion revealed an underwater "mountain" in the center that could hold the center piers, dividing the bridge into two spans of 4 1/2 miles each.

Span 9 Miles
The longer the span, the heavier the bridge.
At the length required to span the Strait of Gibraltar
, a suspension bridge that supports the weight of the roadway with cables spanning from tower to tower would sag and ultimately collapse. A cable-stay bridge that attaches cables directly to the roadway, would require unworkably high towers to support the length of the roadway.
Gibraltar Bridge's designers say why not use both techniques?
The Gibraltar Bridge design supports 3 miles of each 4 1/2 mile span with suspension cables, and the remaining 1 1/2 miles with a cable-stay technique attaching cables to diagonal struts on either side of each tower.
Keep the traffic flowing — and safely
Five lanes of traffic in either direction will flow over a roadbed made of spun glass.
Traffic on Gibraltar Bridge
The Gibraltar Bridge's traffic will flow over a roadbed made of spun glass. Designers say five lanes in either direction should be enough to handle the volume of vehicles.
Fiberglass materials of this sort are rated at five times stronger than concrete, and any cracks or other damage could be isolated due to its web-like internal structure
Engineers say fiberglass bridge materials can last up to 100 years. They're also easier to install. A concrete roadway on Gibraltar Bridge would take 3 months to pour as opposed to a few days or weeks with fiberglass.

I think it can be done but with a lot of problems about people dying.

People tryied to scam them. People did wrong decisions and learned wrong information. There were enough people to build three ships.

I think it is a great resource and a comunity.

Millennium tower in Tokyo

The design calls for a cone-shaped pyramid 840 meters high, with a base about as big as the Tokyo Olympic Stadium and glass sides for natural lighting. It is intended to be constructed on water, with boat and bridge access. Since the tower was planned for an area with frequent earthquakes and hurricane-strength winds, the shape is aerodynamic to reduce wind stress, and helical bands are wrapped around the tower for structural support. Steel tanks at the top of the tower are filled with water, and can be rotated as a counter against wind.
The tower is a self-contained arcology containing one million square meters of commercial development and housing for 60,000 people, split into sections. Offices and light or clean industries are in the lower levels, apartments above, and the top section houses communications systems and wind or solar generators. Restaurants and viewing platforms would be interspersed through all sections.
Horizontal and vertical high-speed metro lines provide long-distance travel, with cars designed to carry 160 people stopping at intermediate five-story 'sky centers' on every thirtieth floor. Each 'sky center' is decorated by gardens and mezzanines, and provides a particular service such as hotels or restaurants. Short-distance travel is by lifts or escalators.

solar energy

Solar energy is the light and radiant heat from the sun that influences Earth's climate and weather and sustain life. Solar power is the rate of the solar energy at a point in time ; sometimes it is used as a synonym for solar energy or specifically to refer to electricity generated for solar radiation. Since ancient times solar energy has been harnesses for humans to use through a range of technologies. Solar radiation along with secondary solar resources such as wind and wave power and hydropower and biomass account for most of the available flow of renewable energy on earth.

I think it's a great resource of energy and can reduce heat on Earh.

Robotic car race in California

Those brave roboticists from Stanford University have decided to tackle the final automotive frontier - commuting. The robotics group whose autonomous VW Touareg, Stanley (pictured), won the DARPA Grand Challenge desert race last year, are building a car that will drive itself at highway speeds from San Francisco City hall to downtown Los Angeles in October 2007.

Spectators gasped as cars with empty driver's seats pulled out of the starting blocks, steering wheels turning on their own, and headed into the neighborhood streets of a deserted air force base.
Stanford University's "Junior" was the first to pass the finish line, followed by cars outfitted by Carnegie Mellon University and Virginia Tech within the six-hour time limit.

Fog screen

projection screen world premiere occurred in October 2002 at the Turku Science Fair in Turku, Finland. Volume production of the Fog Screen projection screen started in late 2004. The interactivity add-on debuted in June 2005, and the 1-meter Fog Screen, Fog Screen One, was launched in April 2006.

All the important principles of Fog Screen technology are patented. The basic components of the screen are a laminar, non-turbulent airflow that remains thin, crisp and protected from turbulence. The fog is made with ultrasonic waves and ordinary tap water - no chemicals are needed. It feels dry and cool to the touch.

This a labeled picture of Fog screen.

robots

The future of robotics has certainly been addressed several times over. From books to movies, virtually everyone has at least some idea of how they believe the future of robotics technology will play out. Joseph F. Engelberger has been widely referred to as the “father of robotics”.He has given many lectures on service robots and what they must have to succeed, such as a magnificent physical execution, sensory perception, prior knowledge of their environment plus expert skills and knowledge and a good cost to benefit ratio.
It is normally assumed that even with future robotics technology most people will be able to perform their own tasks much more efficiently than any robotic alternative. It is also believed that service robots would cost more than human labor which would make them less cost efficient in the long run.
