Amazing Airships - Cargo Transport Reinvented

Amazing Airships - Cargo Transport Reinvented

Airships are designed to be sturdy and cross great distances.  The older airships, such as the Zeppelin, created buoyancy through the use of hydrogen.  Unfortunately, hydrogen is highly unstable and can become explosive if exposed to static electricity or lighting.  The Hindenburg disaster demonstrated how dangerous hydrogen was to public safety when an entire Zeppelin caught fire.  The airships of today have come a long way since the Zeppelin era.  Modern Airships utilize helium, which is stable and safer than hydrogen, to create buoyancy.  To ascend, the ship releases compressed helium gas from its tanks to displace the air that had originally filled the hull.  To descend the ship compresses the helium and allows air to refill the hull.

Northrop Grumman is creating airships for military purposes but Lockheed Martin and Worlwide Aeros Corporation are creating airships for transporting cargo.  The cargo application, especially the Worldwide Aeros Corp., Aeroscraft airship, is appealing because it requires no runway to take off or land.  The Aeroscraft can also carry 66tons of cargo, more carrying capacity than a Boeing 767, which can be transported anywhere in the world.  There is no surprise that most of the capital investment behind these projects comes from NASA and the Pentagon.  The average investment firm is not going to take the risk on an unproven and futuristic helium airship venture.

This technology is important because this capability will allow large amounts of cargo to arrive in remote locations that were traditionally impossible to reach.  This also means that, through the use of GPS technology, these airships can allow distributors to bypass old international transportation routes and deliver cargo closer to the customer.  The need for special equipment and large diesel trucks will eventually become obsolete when this technology is refined and mass produced.

Why this is all important for the environment and safety?

1)         This new technology is better for the environment.  Unlike powerful cargo planes, there is no need for high fuel consumption jet engines and large wing spans to create lift.  These new airships only need enough fuel to propel them to their locations and compress the helium hull for descent.

2)         There is no need for the dredging operations that are required to maintain a port for large shipping vessels.  In order to lower the cost of transportation and increase the profitability of shipping operations many ship builders continue to make their ships even larger than before.  Larger ships require ports to perform more dredging which negatively impacts marine life. 

3)         Airships, unlike large shipping vessels, will not be exposed to the same dangers from pirates.  Airships can cross the vast oceans and never once come in contact with a pirate.  This means the crew will be safer and the amount of insurance required in the event of a loss will be much lower.

Clean Energy: Why It Is Not Catching On As Fast As It Could and What We Can Do About It

Necessity remains the catalyst of all invention.  The need for clean energy has become greater and greater each passing day.  This need has brought rise to an increase in the use of solar panels, wind turbines, and fuel cells.  All of these technologies allow the user to obtain energy at a fraction of the cost of conventional energy costs.  More importantly, these energy sources are renewable and reduce, or prevent, further damage to the environment.  Surprisingly, these technologies have not become ubiquitous in modern everyday life.

Usually, the individuals and business that can afford the initial investment of these technologies are the ones who are able to benefit from them.  Conversely, the ones who need the cost savings from such technology, the financially dependent people and the struggling small businesses, are the ones who cannot afford the initial technological investment.  When credit is tight it can be especially difficult to obtain the financing to purchase these technologies.  The willingness to invest in a piece of equipment instead of having a financial safety net can be tough even when an individual, or business, has saved the required capital to purchase these technologies.

After purchase, the cost of maintenance can also be a challenge.  Also, finding the correct parts and services can be difficult due to the rarity of these products in normal residential and commercial settings.  Though being kind to the environment is appealing the lack of financial attractiveness can derail any plans of utilizing renewable energy.  The cost of insuring these pieces of equipment from natural, and man-made, hazards is rarely mentioned in product literature.  No government entity, or private organization, has been able to implement a comprehensive plan to increase the use of these technologies even with the understanding that there needs to be something done to protect the environment.

Solving the dearth of renewable energy use will require the proper mix of tools to be affective.  First, power companies need to get into the business of selling this equipment to the public and then making their revenue through maintenance.  Second, when a business or an individual purchases this equipment they should be able to claim that on their tax return.  Finally, when an individual or person has excess energy that is placed on to the grid they should be able to earn tax free income from its use.  Utilizing all three of these concepts together will drive the market into a more environmentally friendly direction.
