The motors, sensors, software and batteries of this product are no doubt top end. They also must bear the weight of a regulatory approval process that makes people safe. That means a fall chance of zero because falls can cause significant damage. If you see a thousand dollar version understand the difference - commercial motors, slower response time, less redundancy, less battery life and occasional failures.
It is about staying within safety guidelines mandating the speed of evacuation of aircraft. Beyond that it's about not violating social standards so much that too many fights break out (they're expensive). After that it's about stuffing the most people in with the final limit being not making too many of them so uncomfortable they are willing to pay more for a more expensive seat. There are finally concerns about the actual cost of manufacture of the seats. Southwest has had seats facing each other in exit rows for a long time.
Yep. We could set up a scientific strategy that integrates political, social, environmental, economic and physical sciences in a worldwide approach to generate popular support for fair and wise chosen solutions while attempting manage the benefits and losses to all parties or we could disagree about the number that we won't achieve. The second is much easier.
If you really want to know if it's aliens figure out what stars brightening in that pattern would be useful for outside of signalling. Saying "I'm here" might be reasonable if neutrino beams and stars get cheap but doing something useful is more likely to get funded earlier.
TIL: I will likely be dead before the planets of our solar system are widely investigated. The time necessary to plan and execute an interplanetary mission is daunting.
>I can't see anything negative in promoting talking to professionals.
Thanks, that will be $70 for removing a splinter, $70 for a cold that can't be treated, $70 for a minor sprained ankle that you should just stay off of for a week or two. There are times for professionals and there are times that they simply aren't needed. If you don't have hundreds of dollars to spend listening to people tell you something is minor and to come back if it gets worse then you need to use sound judgement instead of running to the doctor with every boo boo. Sound judgement includes consulting reasonable information sources but it all to often seems they are paywalled, tort-terrorized into saying "just see a doctor" or blocked out by quackery websites.
That doctor traffic also is why often you can't get an appointment to have someone look at a significant condition for a week and a half and why Americans go to the emergency room so often - where they can wait long periods before being treated for serious issues. That is the downside in promoting talking to professionals. There is no downside in shooting down quacks unless worse quacks take their place.
After the auction the Bitcoins will be confiscated as they were previously the proceeds from illegal drug transactions.
So much for being anonymous. That's even better for tracking than a bar code tattoo.
They have to be thinking LifePO4's and recharge cyclability. I've been trying to justify moving to lithiums for five years and the economics never even come close unless you count in charge cycles on the lead acids or need the light weight.
