[Gasification] OT, now, Boat pulls easier than Cart?

[Warner Kimo Sutton]

Here in Hawaii the wheel came with Europeans. 
People from the South Pacific came here not knowing the land was here. Then had to come back with more people. No GPS.

 Distance on island was short and meant hand carrying, but between islands the sail was most efficient. 
When the wind was light  they paddled and at night used the stars to navigate. 
Imagine them sailing the whole Pacific before the horse went in front of a cart. 
Okay the wheel was a great invention but the ability of an ancient peoples to understand navigation was a science learned as now an almost lost art. 
No trails no maps no wheels. Just one known man still knows that art that take a lifetime to learn and pass on from the last master.
So they used the wind to pull (yes not pushed)the canoes and made the largest area populated by one race of their time-Polynesians.

We really need gasification of biomass on a large scale here to make local energy and fuels as ships do not sail here on the wind with oil.
Old tech is new tech. Now how about talk back on topic.
 Happy Memorial day in the USA.

Dear A.D. Karve:

Are you suggesting that it was the invention of "smooth roads" that spurred
the subsequent invention of the wheel?

The indigenous peoples of the American Great Plains were migratory and
dragged their possessions on high-friction sledges. The "Pioneers" of the
mid-19th Century had wheeled conveyances and followed "trails" not macadam.
Wagon Trains. The Spanish who conquered the great Inca empire had wheels, an
unthought-of notion to indigenous cultures over 10,000 years old.

Why didn't Nature provide hummingbirds with a rotary wing? Rolf gave a good
clue.

Best, Mark

Best, Mark
