In the seventies there was not even a single thought about an electric  
powered RC helicopter, much less multi-motor quad copters.

  Now, they are talking about mass producing a pilotless whirly bird  
taxi srvice.

  Folks are already buying up rooftop landing pad space leases.

Maybe that was because the rechargeable lithium-ion battery wasn't invented until 1980.

  And the world and industry still used heavier NiCad batteries  
until more recently.

  The tech will get better and better.

  Nanotubes, and graphene...  all kinds of potential.

  A graphene sheet condom you do not even know you are wearing (till  
ya have to piss).

  That graphene sheet could also make for a better supercap, which  
is an inroad to calling the things batteries at some point.  I am  
amazed at how light LiFePo batteries are for the same AH rating.(and  
amazed at the prices the greedy bat's turds are charging for them.

  The condom thing was just a joke.

High-end battery-powered drones can stay in the air about 20 minutes,
with no payload except a small camera. A weatherproof, enclosed drone
with passengers and luggage isn't going to make it very far.

Like the orders at that show determine everything?  Figures you'd choose
the socialist company over the private one.   Airbus just had a spectacular
fail with the A380, which is headed to the scrap yard fast.  Boeing sure
had that right.  Airbus bet 15 years ago on a huge plane for a hub model
future.  Boeing said, no the future is more long, direct flights.  They
bet their future on the 777 and 787 and they were right.



 and ASML in the Netherlands now dominates the semiconductor lithography ma

Well whooptie dooh!  And WTF does Australia dominate?  Kangaroos?

I'm sure you are correct - Bhopal, Love Canal, overcrowded ferries  
sinking, no food inspections, etc. are a but small price to pay for  
progress. Who needs regulations after all?

However Canadians are kind of stupid that way, we think our government  
is here to help protect us from unscrupulous people, countries, and  
companies.

Nobody's perfect, so any government can go off the rails from time to  
time... Keeping a rein on government's excess is what elections are  
supposed to do.

 An item like that will be an airplane, not a drone.

 Cape Air is adding a few dozen all-electric planes
 to its fleet, for its short-haul passenger routes.
 They expect to save $400 in aviation fuel per trip,
 compared to $10 for the electricity fillups.  With
 many trips/day the E-planes will pay for themselves.

It will have the same dronish vertical takeoff/land props, so has the
same energy and reliability issues. And many of the proposed shuttle
things have no pilot, which I might call "drone."

I was talking about downtown rooftop to airport shuttles. Electric
winged planes might well make sense for short trips, like SFO to the
Oakland airport maybe. Recharge time will be an issue.

An electric powered sailplane would be cool, to avoid the tow.

The numbers don't look great there. It weighs 4850 lbs to haul 4
passengers and has 20 minute endurance.

We'd need seriously better batteries to make this sort of thing
practical. It would need more energy per kg and very fast recharge
times to be economical.

Some sort of tiltrotor would be more efficient but probably not very
safe.  

A lot of people have been working on this sort of thing for a while
now.

They showed one on the news last night, in OR I think, at a testing
facility.  It held a few people, had a range of 35 miles.  It could
still be fine for a commuting service, ie to get commuters into and
out of NYC, but there would have to be a big field somewhere for them
to go to, land, sit and recharge.
