;-) YES JIM MOBERLY : Typically flexpipe is plowed at up to 4mph or trenchless microtunneled with HDD or mini-boring. [ youtube: wolfe tile plow ]

But since Alaska is in such a procrastinated emergency, we can take many quick shortcuts just tossing it everywhere and pass gas with it until we get around to plowing it in later. Yup, it can be airlifted and deployed over glaciers with no enviro-effect. This will quickly get us to CASHFLOW=GASFLOW.

Flexpipe does not require building access roads.

Using GRAPHENE + BASALT FIBER our flexpipe will be bulletproof too. We have a zillion tons of graphite+basalt in AK.

AKRR might still be stalled getting PosTrainControl completed. 3yrs ago I mapped out a flexpipe gasline along the RailROW between BigLake and FBX. A Parks flexpipe can offer a dedicated fiberoptic conduit for rail-PTC and dovetail with converting AKRR SD70MACs to dualfuel LNG/diesel +CNG/ANG locomotives.
