Tûranor PlanetSolar World’s Largest Solar Ship About to Complete Trip Around the Globe

The epic voyage of the Tûranor PlanetSolar – the world’s largest solar-powered boat – will soon come to a close as the ship closes in on its final stretch. The Swiss vessel is a full-bore high-tech solar harvesting machine whose deck is covered in 537 square meters of photovoltaic panels. The array produced enough energy for the boat to navigate the entire circumference of the Earth without any other means of energy. The Tûranor PlanetSolar is currently set to depart Abu Dhabi en route to their final port in Morocco – the same place the expedition launched on September 27th, 2010. The journey has come full circle in more than one respect, as it was not too long ago the only way to navigate the earth was by harnessing renewable energy with sails.

The current scenario

Transportation technologies have got a new form over all these years and have made traveling comfortable and convenient. There are a variety of transportation modes that help us travel all around the globe in no time. But, the saddest part being that the world is still ruled by gas-guzzling beasts that are threat to the environment. Efforts are being made to give the world environmentally-friendly vehicles that will be effective, energy efficient as well as clean. Public transportation systems, like buses, trains, airplanes, etc. are also getting an eco friendly streak as they run using solar energy and electricity. Such vehicles not only save precious resources but are also superior to gasoline driven vehicles as they are harmless for the surroundings.

Hybrid solar-wind power connects rural Navajos

by Martin LaMonica

Power transmission lines run a few hundred yards behind the Johnson family home here, but it took an off-grid solar and wind generator to finally bring them electricity service.

The Johnsons, who live on a remote stretch of land on the Navajo Reservation west of Farmington, N.M., are among about 200 families on the Navajo Reservation who rent an off-grid renewable-energy system from the rural utility. They opened their home to visitors last week during a fellowship organized by Institutes for Journalism & Natural Resources.

As we know it

One of the most respected names in the field of Aeronautics is Lockheed Martin. The firm has also ventured in areas of information, electronics, and the space systems. A new airship, which has been given the name HALE, has been recently manufactured by the firm. HALE D is the short for high altitude long endurance demonstrator. The big robot airship can easily operate at an altitude of 60,000 feet and has a big robot airship design. A series of photovoltaic cells are contained in the airship.

Solar Ship The hybrid airship with a low-carbon twist

Email, RSS Follow

In recent times there’s been a resurgence of interest in airships for military and commercial uses as evidenced by Lockheed Martin’s High Altitude Long Endurance-Demonstrator (HALE-D) and Hybrid Air Vehicles heavy-lift variant of Northrop Grumman’s Long-Endurance Multi-Intelligence Vehicle (LEMV). Like HAV’s design, this concept from Canadian company Solar Ship is a hybrid airship that relies on aerodynamics to help provide lift, and like the HALE-D, it would have its top surface area covered in solar cells to provide energy and minimize its carbon footprint.

Lockheed Martin’s HALE-D airship takes to the air

Email, RSS Follow

With the use of airships for passenger transport decreasing in the early 20th century as their capabilities were eclipsed by those of airplanes – coupled with a number of disasters – they were largely resigned to serving as floating billboards or as camera platforms for covering sporting events. But the ability to hover in one place for an extended period of time also makes them ideal for intelligence, surveillance and reconnaissance purposes, which is why Lockheed Martin has been developing its High Altitude Airship (HAA). The company yesterday launched the first-of-its-kind High Altitude Long Endurance-Demonstrator (HALE-D) to test a number of key technologies critical to development of unmanned airships.
