You can reach *any* orbit from *anywhere*. But it uses more fuel form some places. For a polar orbit shedding the rotational speed you already have is wasted deltaV.
You not suppose to use the numbers directly. If you want more than 10 billion devices on the internet, why would you expect to "remember" the address. Do you even bother remembering phone numbers anymore?
About haft the mass of the asteroid belt is in the 4 largest bodies. Also note that is half of the *estimated total mass*. We have very accurate orbital models and combined with what we have seen we can get fairly accurate estimates. It is very unlikely to get a big surprise. Because as you say, it would be easy to detect it.
New Zealand is about 20000km from where i currently live. at 0.2g max acceleration you can cover that distance from stationary starting to stationary stop in less than two hours (6300seconds). So your idea of forces involved for high speed are quite false. Of course in this example top speed would be 6232m/s, or about 15% below orbital speed. quite impractical for a plane, or even this concept. But it illustrates the point.
In short your top speed is what matters. There are no inherent forces that kill you at speed and acceleration can be very mild.
The problem with fiction based jet packs, is that the physics just doesn't work. Energy density required means very short flight time with supersonic jets that will rip/burn your legs off.
They run at a different regime where 5ms (up from about 100microseconds) could be more than enough. The collide two RFC and this should heat them quickly to fusion temps. Even better most of that "heat" will be in the ions rather than the electrons.
The thing about all three of the current top gear guys is that they are utter toss pots. And its not Clarkson that has make it work. Its the producer with some of the best editing and camera work in the industry.
for me the biggest problem with self-driving cars is legal liability.
This is already covered. Brakes fail, tires blow out, mechanical failures happen. They kill people. Its been something that has happened plenty and gone trough the courts many times. Precedent has been set.
Actually its not. The TFA makes the same comparison so many do with solar. That is per watt installed. Which is total bullshit. That watt of installed power will only produce 1 watt, for about 30min on just one perfectly fine day in the summer, if its in space. I like to call them brochure watts. Since real installations are probably never ever going to get that claimed watt in any real life conditions.
The average power you get out of 1GW of solar panels is at best 32% of the peak (in practice it is quite a bit lower, like 25%), and only in summer. It is much lower in the winter months, and you will often need to "time shift" all that energy.

Its 2015. Everyone is a expert in networking cus they changed the password on their home router. And NAT is a firewall!
Joking aside. 99.99% of people have not idea on just how much NAT breaks things. And how it add zero security.
Polar orbits come to mind.
NZ is not the US. Just because you have money, doesn't mean jack when it comes to "suing" people.
In fact some ISPs have been providing the VPN for netflix etc. They are currently getting into a legal dispute over it.
You first Coward.
However i am. And he has done a good job. the data is public. You can replicated the results.

Yes and a 4min flight time. Yea really useful, not.
I can slow down for the sharper corners. Like High speed rail does you know. Since its a v^2 term you don't need to slow down much.

Some hydrocarbons are pretty nasty to humans. And yes they can occur in wells anyway. It pays to test.

And yet airline accidents have been and are far worse. Probably the up to 100 tons of volatile jet fuel on board.
But but ... 5 mile high club!!!
Or we just could get rid of faulty flesh computers in first place and have non overidable "autopilot".
Fact is, that is the only way to be sure. The certainty presented in current models is nothing short of intellectually dishonest at best.

Its a tide. Its 5m. For an average of 2.5m.
Pump storage can't be built everywhere. And the capacity needed is insane for a a 100% renewable grid.
But they need to be about 200C to work. This is not very good for domestic applications.
