Actually, an 18th century scientist could have designed the GPS system with the basic science of the time... They didn't know about radio, but they could have invented a night-only system based on light pulses.
Stars? Celestial navigation?

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Blades are blown horizontally away from the hub, giving enough time for the most part to allow for ejection. Does that only work because they don't have a tail rotor? By destroying the linkages between the blades and the main rotor shaft, the blades will fly away from the rotor shaft on their own d...

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Found out the Russian Black Shark helicopter gunships have ejection seats (as do the 2-seat variants). They blow the blades off first. I don't know how they end up controlling where the blades go after they get ejected but they claim it works. Then again, they claimed the machines worked in the dese...

Re: New $800million superyacht design

$100m for a giant container ship, so call that megayacht a $25m or $50m ship with a lot of handcrafted interior fittings. :-) To be realistic, something that size, if built, will be bought and used as a charter yacht but at that point the difference between yacht and cruise liner become a bit hand-w...

Re: State of the Mongoose 2018

Regarding the Vanguard miniatures game, the major issue with the last campaign was that the buy-in was limited to a full set only, which was a high price-mark for an entree point. Would it it be worth considering selling smaller, individual packs of miniatures (like a ship crew set, or a pack of As...

Re: Future TLs, or different types of "impossible" in scifi

It's categorized as such, since I think the primary users are corporations, or are chartered by corporations. The military have also adapted some of them as communications, surveillance, and I think ambulance aircraft. I think the Iraqis may have also reconstructed one as a missile platform. It's g...

Supersonic business jet is clearly possible, but utterly un-economical.
We had them, called the Concorde.
Although the cut-off point is arbitrary, business jet means "small private jet".

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Just imagine open frame at 0.99 mach :-) How do pilots survive ejecting at supersonic speeds? They usually don't, but ejection involves a lot more forces than regular flight. Wikipedia gives all these awesome mach 2 speeds for jet fighters but that's for unloaded aircraft that don't have to save fu...

Fighter jet can do "brakes off to mach 1" in about 30 seconds. Just imagine open frame at 0.99 mach :-)

Re: Future TLs, or different types of "impossible" in scifi

Any new device or process is an invention. The Chinese regard their stationless vehicle hire as a genuine radical breakthrough. Using this system vehicles can be picked up and left anywhere, with the app locating nearby units. I believe the company moves them around in the event they get into inconv...

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Open Frame The smallest Light Grav Vehicles can be built as an open frame with passengers effectively sitting on top or astride it. The g/bike is a good example of such a vehicle. They tend to be extremely fast but, without adequate computer-assisted controls, utterly lethal. Both Open Frame and St...

Re: Future TLs, or different types of "impossible" in scifi

China does invent, but it's specialised engineering stuff that doesn't make headlines. Newspapers care about a new iPhone - but not about a new process engineering technique for electronics factories, or a new KBBF laser crystal.

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Mongoose 2 allows any light grav vehicle to be open topped and has a note saying they require computer stabilisation. You certainly could exceed mach 1. That's information given to me by a friend who has the vehicle book so apologies if misquoted. As has been said, it could be a rules oversight.

Re: A lot of worlds over 1g gravity. How do 1G thrust ships take off?

Grav vehicles still have a stated top speed, implying drag. The Vehicle Handbook says: Streamlined High performance grav vehicles can be designed with aerodynamic hulls that allow them to travel at much greater speeds. Does Mongoose 2 antigrav produce "thrust" in the conventional sense? It moves a ...

Re: Future TLs, or different types of "impossible" in scifi

The only caveat I would submit to putting FTL in category 5 is wormholes. They are theoretical, but to my (limited) knowledge, do not violate fundamental laws of physics as we understand them today. While wormholes are permitted under general relativity, no-one can explain how they don't cause back...

A recent thread made me decide to categorise this. (1) We can do it (maybe for some time) but never thought of it. The ancient Romans had polyhedral dice and writing.
