If blimps could go into orbit of any kind, we'd have settled Mars by now. Donald Trump is a one-term LOSER |

Evenbob Member since: Oct 24, 2012 Threads: 146 Posts: 25011 | I grew up in the 50's watching movies and TV shows that had landing rockets. This looks like a bad TV show landing. Who knew in 1955 that it would take another 60 years before we could land a rocket safely. If you take a risk, you may lose. If you never take a risk, you will always lose. |

petroglyph Member since: Aug 3, 2014 Threads: 25 Posts: 6227 | I have wondered if super giant blimps could be attached over the tops of ocean cargo or tanker vessels and lift mega tons out of the water to help the ships burn less fuel in ocean crossing? The blimps could also be solar powered with PV arrays across the tops of the balloon. Already giant sails have been attached and reduced fuel costs. Cool rocket Paco The last official act of any government is to loot the treasury. GW |

DJTeddyBear Member since: Oct 24, 2012 Threads: 5 Posts: 265 | If that would work, why not just use the blimps for the cargo itself, and eliminate the ship? Ignorance is bliss and knowledge is power. But having only some facts can get you into trouble! |

A container ship fully loaded would take fleet of blimps. Which don't do well in bad weather. If you take a risk, you may lose. If you never take a risk, you will always lose. |

Certainly much of the weight that has to be carried is the rotors and crew. I'm thinking electric, [solar powered] or smaller rotors and a larger craft, that is reusable over and over again. It could unhook during threatening weather and just let the ship, be a ship. The dirigible could also be largely autonomous or remote controlled. Tankers can weigh up to 400k tons. http://www.jobmonkey.com/oilindustry/oil_tankers/ hard to find a place to park a balloon that would carry that much oil. The sail attachment pic I posted seems to be +ev, I just wondered if making a ship weigh less and raise some of the hull out of the water might be more +ev? Reduce displacement? Oil tankers burn around 200 gallons of fuel per mile. The last official act of any government is to loot the treasury. GW |
