9. Pumpabike
Riders operate the “Pumpabike” by bouncing up and down on a small platform at the rear of the contraption, whilst holding onto a steering column at the front.

In doing so, they can reach speeds of up to 16 knots (30 kilometres per hour), says inventor Mike Puzey, who is based in Johannesburg, South Africa. Puzey’s design has no propeller and involves no pedalling. Instead, thrust comes entirely from the hydrofoils beneath the craft.

The vehicle is made from plastic and aluminium, and weighs just 14 kilograms. It has two hydrofoils, a large rear one that generates 80% of the lift, and a smaller one at the front for steering and stability. Each craft costs between $800 and $1200, depending on its configuration and where you buy it. Check out pumpabike.com for more.

8. GIBBS Quadski

Quadski is the third demonstration of Gibbs’ HSA technology following the successes of the Aquada and the Humdinga. It is capable of travelling up to 50 mph (72 kph) on land and water and makes the transition at the flick of a switch. Commenting on the launch of the Quadski prototype, Alan Gibbs, the founder of UK based Gibbs Technologies Ltd. said, “Quadski is both exciting and practical with a multitude of uses”.

“I know consumers will love the fun of driving a Quadski on land one minute and then head straight into the sea or river the next. But there is a very serious side to Quadski as well: emergency services and aid workers will be able to reach areas and people no two or four wheel drive vehicle could reach.” Don’t you just want to get your hands on one of these.

7. PowerSkiJetBoard

One of the most radical water toys ever invented, the PowerSkiJetBoard is an engineering masterpiece - the inventors have taken the form factor of a surfboard and built in an ingenuously small and flat 45 horsepower motor capable of propelling it to 40 mph. With the rear thrust, rail and the three fins beneath, the JetBoard carves better than anything else on water, tarmac or snow, generating G-forces up to 6G and enabling the rider to get almost horizontal (check the pics inside). The JetBoard never cavitates or slides out, enabling a standing rider to perform continuous, stable, high speed turns with slight shifts in weight. Check out powerski.com for more.

5. GIBBS Aquada

The Aquada is a revolutionary showcase of High Speed Amphibian (HSA) technology.

This radical new breed of vehicle has been precision engineered to the most exacting standards. It has undergone an extensive safety testing programme and complies with appropriate marine and road safety regulations.

Entry to the water is via beach, boat ramp, slipway or directly from the water’s edge. Once afloat, the transition from road vehicle to High Speed Amphibian (HSA) is effortlessly achieved.

Simply press a button and drive into the water. The wheels automatically rise and as you press the accelerator nearly a tonne of thrust pushes the Aquada onto the plane. The whole process takes less than 12 seconds. The Aquada can plane at over 30mph.

Powerful enough to tow a water-skier and with a style and class of its own, the Gibbs Aquada is the perfect leisure vehicle. It combines the thrill of an open top car with the sheer exhilaration experienced in a high performance speedboat.

The Aquada is the new name for freedom! Check out gibbstech.co.uk for more.

4. GIBBS Humdinga

Although the new application utilises the same patented HSA technological platform as the Aquada, it shares no common component parts or systems with its predecessor. It has been designed specifically to access remote and hostile terrain. The Humdinga can comfortably transport 5 people complete with luggage/supplies on at least twice as much of the world’s surface as previous vehicles.

The Humdinga illustrates the scalability and versatility of HSA technology. HSA Technology can make vehicles ranging from passenger cars to SUVs to buses and trucks High Speed Amphibians.

The Humdinga transforms from land to water mode at a touch of a button. The wheels retract, the power train switches from the wheels to a jet propulsion system and the vehicle is in amphibious mode. In just a few seconds the driver is planing at a speed of forty miles per hour.

“This 4WD HSA demonstrates that the technology is adaptable for a whole range of applications. It took us 8 years, a million man-hours and tens of millions of pounds to develop HSA technology. With this latest vehicle, I’m sure that the technology’s potential is clear for all to see.”, comments Alan Gibbs, Chairman of Gibbs Technologies.

On land the Humdinga can accelerate from 0-60 in 9.2 seconds and on water can reach the ‘plane’ in less than 10 seconds. It has a curb weight of 2000kg, has all wheel independent air suspension and runs on regular unleaded petrol. The vehicle is 5400mm in length, 1850mm in height and 2000mm in width.

2. Dolphin watercraft

Innespace Productions is a company dedicated to creating and demonstrating high performance submersible watercraft. Innespace was started in California in 1998 by Rob Innes and Dan Piazza, with the aim of providing thrilling aquatic demonstrations using our unique Dolphin watercraft.These positively buoyant vessels use their forward momentum and the downward lift of their wings to literally fly below the water’s surface. This radical departure from the typical method of sinking below the surface allows the Dolphins to achieve an unparrallelled level of freestyle performance.

The first Dolphin to be designed and built by Innespace was Sweet Virgin Angel. She was completed in 2001 and has been performing at shows and events for four years. The Innespace Dolphin is a fully functional show ready watercraft, able to perform sustained dives, huge jumps, barrel rolls, and many other amazing acrobatic tricks.

1. Phoenix 1000

The Phoenix 1000 is a 65-meter (213′) personal luxury submarine. The initial design was originally executed for a client and now awaits a buyer. As proposed, the submarine would constitute the single largest private undersea vehicle ever built, and arguably, one of the most significant personal transportation devices of the century.

A Luxurious Undersea Vehicle

This design, which we have named the Phoenix 1000, has more than ample space. The total interior area of the submarine is in excess of 460 square meters (5000 square feet). The significant volume, coupled with very large acrylic viewports, and the potential for relatively large open spaces, results in a vehicle as luxurious as the finest of motor yachts.

Clearly, the Phoenix provides its owner with substantially more capability than a simple yacht - the opportunity to explore the depths of the world’s oceans in perfect comfort and safety. The Phoenix is capable of making trans-Atlantic crossings at 16 knots yet can dive along the route and explore the continental margins of some of the most fascinating waters on earth. And unlike surface yachts, when the water gets rough, the submarine can submerge into a perfectly smooth and quiet environment, continuing on toward its destination, providing a ride unsurpassed in quality-unequaled by the finest motor coach or the most luxurious executive aircraft.

The Size Advantage At 65-meters (213 feet) in overall length, and with a beam in excess of 8 meters (26 feet), the Phoenix is a vehicle of formidable size. Yet despite its 1500-ton displacement, the submarine is quite streamlined. Given the significant waterplane area and ample internal volume, which allows for greater battery storage, the Phoenix will out-perform smaller counterparts in surface speed, submerged speed and submerged endurance. The large pressure hull diameter allows for very large acrylic viewports, making the undersea viewing capability truly extraordinary. The interior space, with the noted absence of structural bulkheads, provides for tremendous versatility in interior layout and space planning. And finally, the Phoenix’s large size coupled with its integrated roll stabilization system makes surface transit quite comfortable in all but the worst conditions.

A Walk Through the Phoenix Join us as we examine the physical spaces of the Phoenix 1000.

Flying Bridge The uppermost level of the vessel is the flying bridge. This area is similar to its equivalent area on most yachts, with the exception of the fact that the materials selected are subject to immersion in water. Ample space exists for lounging, and cushions may be brought up from the area below. The flying bridge also houses the pressure-compensated radar radome, GPS antennae and satellite communications radome, as well as radio aerials, running lights, etc. A remote steering station is also available.

Deck Saloon Immediately below the flying bridge and accessible through a large hydraulically operated hatch and a stairway, is the deck saloon. As proposed, this area would be composed of structural acrylic cylindrical sections 2.1 meters (7′) in diameter and 20 centimeters (8″) in thickness. The overall length of the deck saloon pressure hull would be 12 meters.

The deck saloon would have a comfortably appointed interior and would boast an incredible view for observation, both on the surface and when submerged. By fitting transparent sections into the deck of the flying bridge, a view above can be enjoyed as well.

In the forward portion of the saloon is the surface bridge. This area contains all the necessary control, monitoring and navigation equipment to operate the submarine in the surfaced condition. The captain has a hemispherical sector acrylic viewport immediately in front, with the transparent cylindrical walls to either side.

The aft portion of the saloon has a large acrylic window, providing a view astern that also acts as a large hydraulically operated hatch. A small automobile could be kept in the aft section if desired.

Superstructure The superstructure itself is composed principally of aluminum (or FRP if the owner prefers), and it houses the deck saloon pressure vessel and also provides the structural base for the flying bridge. There is a large degree of latitude possible with regard to the styling of the structure, with the caveat that its hydrodynamic efficiency will have a significant effect on the submerged speed of the submarine.

Aft of the deck saloon is a covered space that can be either fully or partially enclosed. The greater the degree of closure to the after portion of the structure, the less turbulence and the more hydromdynamic efficiency. Hydraulically actuated after doors could be designed to open, allowing fresh air to circulate. The area would be excellent for covered, informal, deck- level dining.

Docking Minisub Aft of the superstructure, or optionally, above the control cabin on the bow, is an area for a docking minisub. Utilizing a special docking collar, this vehicle is capable of leaving the Phoenix while submerged and making excursions down to 610 meters (2000 feet). With both top and bottom hatches, the minisub could also bring passengers from the surface to the submarine lying at depth. The minisub could be designed to hold between two and eight passengers, depending upon the owner’s preferences. Additionally, in the unlikely event of an emergency at depth, the minisub could be used to take passengers and crew to the surface.

Forward Control Room The forward control room is entered from the main deck through a watertight, pressure-proof door. The control room has a 2.4 meter (8′) diameter hemispherical sector acrylic viewport forward and three 1.8 meter (6′) diameter viewports on either side, with the foremost pair angled slightly forward.

The control room contains all of the control and navigation equipment necessary to operate the submarine while submerged. The 8 meter x 4 meter (26′ x 13′) area contains sufficient space to fit comfortable lounge chairs for passenger observation while underway.

Main Passenger Areas The main passenger area consists of two decks, each 31 meters (102′) long and 6 meters (20′) wide. The upper deck is accessed from one of two hatches, either from the deck saloon or from a hatch to the after portion of the superstructure. Two stairways, one in the center of the deck, the other in the after section, lead to the lower deck.

The upper deck is intended to provide space for an engineering workstation, a switch and contactor room, crew cabins and mess, as well as the galley. The forward portion, which ends at a bulkhead, is designed as a room of the owner’s choosing.

The main deck is situated such that the forward portion, with eight 1.8 meter (6′) diameter acrylic windows, contains the living and dining areas, while the section aft of the beam houses the owner’s stateroom and guest cabins. Five viewports, 90 centimeters (35″) in diameter, are situated on both port and starboard sides.

Below the passenger area is the battery compartment and bilge. A narrow manway allows access through the compartment for battery maintenance.

Engine Room The engine room is accessed through doors at the after portion of both passenger decks. The space contains the majority of the equipment necessary for the submarine’s operation, including the main diesels, motor generators, drive systems, air compressors, hydraulic aggregates and life support systems. The upper level of the engine space provides access to the minisub, and in the stern section, to a diver lock-out chamber. The bottom level allows maintenance of the main engines and related components.

Diver Lock-out Chamber A spherical diver lock-out chamber, 2.4 meters (8′) in diameter is fitted above the shafts and attached to the aftermost section of the pressure hull. The chamber allows a diver to enter or exit the submarine from the area between the shafts at depths of up to 45 meters (150′). The chamber can be fitted with decompression capability if required.

Commercial Opportunities The Phoenix would be suitable for use as an exclusive submarine cruise ship or as a charter yacht.

The estimated price of the Phoenix is $78 million.
