These are her suicidal problems but that wasn't a problem according to the DHS. Her hospitalization for clinical depression in 2012 was. That is nowhere mentioned in the links (the book is from 2009).

I am using a ReadyNAS Duo running Free BSD. The NAS is in a cupboard a a friend a few houses away.

For syncing I use Unison. The initial backup was created onsite. Every night I run an incremental backup. When local drives are destroyed it is only a short walk to get my data back.

It all works like a charm.

GP has already used all the supposed finite number of prime numbers in constructing his contradictory bigger prime.

The proof constructs a number that is not divisible by any of the prime numbers in the set of all prime numbers. Therefore it proofs there are an infinite number of prime numbers. The conclusion the constructed number must be prime is wrong.

You now have a number that is divisible by none of the primes, which therefore must be a prime number.

Or the number is divisible by a prime that wasn't in you initial set.

The Greek knew in 300 BC there are an infinite number of prime numbers. The same proof also shows the gab arbitrary between two numbers can be arbitrary large (even larger as 70 million).

This proof shows there are an infinite number of primes that are 70 million or less from each other.

If the US companies are stalling this development I bet soon enough some Japanese or Chinese companies think is is a great idea and start selling it all over the world. Just like electric cars, pv solar cells. US companies may even try to block import of those great power supplies and make the US into some backward country where they are still burning fossil fuels for energy while the rest of the world moves on.

To accelerate a 100000 pound object to 240 mph requires an energy of 260 MJ (sorry I converted all units to SI before I started calculating so you have to convert it back to BTU or kcal or whatever the right unit for energy you want to use yourself). Assuming a linear acceleration over 300 feet to 240 mph gives an acceleration time of 1.7 s. This results in an average power of 153 MW. AFAIK there is no electrical turbine that will supply an extra 153 MW at the flip of a switch. Electrical energy has to be stored somewhere to let the catapult work.

They run at gigahertz speeds, which implies nanosecond timings. A flywheel with decent mass spinning a million RPM is only four orders of magnitude away from the speed of light.
It all depends.

Speed of light: 300e6 m/s
Speed of micrometer scale graphene flakes spinning at 60 million rpm:
2*pi*1e-6/1e-6 = 6 m/s = 21.6 km/h
I think you can get any material spinning at 60 million rpm at micrometer scale. Tensile strength is not very important at these speeds.

It is a nice trick though.

Genes determine what is possible. But the environment determines whether these possibilities actually happen. In case of height I think food is very important for the expression of the genes.

At the moment I think it's aimed at typical commuting distances. 360 km is a very long ride! (How long does that take?!)

Actually it is close to 400 km (A120, A12, London city center, A4, A30, A303). My best time is 14 hours, worst 20 hours. For the return journey I allot 24 hours because I don't want to miss the ferry. But 400 km isn't that a big distance when you train for rides like Paris-Brest-Paris or London-Edinburgh-London.

Even in the Netherlands we do not have a satnav app for cyclists on the iPhone. Route for cyclists can be done by the excellent 'fietsrouteplanner' planner from the Fietsersbond (http://www.fietsersbond.nl/fietsrouteplanner/fietsroutes-vandeurtotdeurplanner/index.html). This great planner has lots of options and biker profiles (like shortest route, avoid busy traffic, green route, social safe route, racing cyclist, etc.) but once you are cycling it is quite useless. The route is static, has no rerouting when you choose an other route due to roadworks or just because you felt so.

I immediately tried out this app but was a bit disappointed. I cannot plan a route from Harwich to Exeter, a route I have cycled multiple times to visit family in England.
