While Peak Oil and Climate Change are being debated by politicos, the nerds that actually bothered to attend math and science classes and listen are telling us it is a rapidly changing world, and not for the better. Population growth and global warming are increasing at a break-neck speed.

Although your life seems normal now, it won’t stay that way. Wind, solar, and nuclear energy projects of the future won’t be built on the basis of a referendum. They will be mandatory. Cars will have to go hydrogen (derived from electrolysis) or electric.
And so will planes. The future of the airline industry for rapid travel about the globe will have to change. Jet aircraft will have to adopt hydrogen as a fuel. But there is an alternative. It is slower and harkens back to an earlier time, but modern technology breathes new life into the concept of an airship.
By combining several unique concepts, modern airships will revolutionize air travel, carrying 5,000 passengers at a time for the cost of construction and maintenance - no fuel involved.
The major problem with airships in the past has been two-fold:
1. They required ballast to offset lift, therefore the ballast and the lifting gas became consumables, each one in turn having to be jettisoned to make the craft rise or fall.
2. They could not land like a plane. A ground crew was required to handle the lighter-than-air craft, and it could not be done in a stiff breeze.
These two problems and more have been fixed. You start with a lighter-than-air lifting body and add wings and a solid floor to which everything is attached. Flexible solar cells cover the body and power up lithium-ion batteries which turn motors and props, thrusting it through the air silently without products of combustion fouling the atmosphere.
The helium lifting bags are the key to making the airship work properly. They provide the lift to allow this ship to carry thousands of passengers or heavy cargo. Unlike in the past, however, the lifting gas does not have to be discharged to allow the ship to land. Instead, pumps suck out the helium gas, storing it in pressurized containers for re-use. This causes the lift bags to be variable in their lifting capacity, allowing the pilot to switch to a slightly heavier-than-air mode for more maneuverability when landing. The fact that it can land and be hangared like a plane greatly increases its safety in inclement weather.
The rich will always ride their jets of combustion no matter the cost, but for millions the price of airfare could drop dramatically with the advent of solar-powered airships. We should start talking about planning and implementation now because it is not a matter of if but when.
