This got long

It may be the future but we will still have to get from place to place.

Not only will we not escape the deadly scourge of the bicycle, they will diversify into even more deadly forms.

This is basically a Smart Car, as seen from a decade with ugly fashions.


145

And this seems largely correct: I remember how futuristic our 1978 Honda seemed...

146

Hey, remember maglev? It was a thing. Like bell-bottoms. Only very very expensive.

I was *just* reading something with a gratuitous hovercraft. Not Systemic Shock, although as I recall that had all of Israel prepared to flee from Israel in a mighty hovercraft fleet.

With all due respect to a frequent reader of this LJ, I do not expect these to, ah, take off.

152

Or these.

154

And I expect airships will continue to be slow, fragile and expensive compared to planes.

157

The shuttle: doing the job of a dozen rockets at the cost of two dozen rockets!

160

What happened to Truax, anyway?

162

This quickly dashed off starship makes me sad.

And because they couldn't go an entire chapter without Woo.

The Marines think our hovercraft landing craft (LCAC: Landing Craft Air Cushioned) is pretty cool, but they're being replaced, because they have crummy availability, i.e. they're broken all the damn time. It has something to do with having a jet turbine ingesting salt spray all the time, and also something to do with lots of moving parts.

The proposed replacement vehicle looks like something out of 1960s SF to me, the UHAC: of the Ultra Heavy-Lift Amphibious Connector, which is kind of like an amphibious assault vehicle crossed with a paddleboat and dreamed up by Games Workshop. The thing seriously looks nuts: http://www.marinecorpstimes.com/article/20140318/NEWS04/303180049/Marine-Corps-Warfighting-Lab-assesses-potential-landing-craft-replacement
http://www.cnn.com/2014/07/16/tech/innovation/marines-amphibious-vehicle/

The advantage is because it actually floats, it has cargo capacity like traditional landing craft (LCU: Landing Craft Utility), but it can go ashore, and with the treads it can cross terrain impassible to the hovercraft, like breakwaters.
