The FH will launch, they've pretty much finished the build of the first one

I really hope he can keep the momentum going.

There's something odd in that I don't doubt he'll get something to Mars for a second, but if he can make sub-hour flights to the other side of the world commercially viable I'll be even more amazed. At least someone's trying though.

People are missing a dream, hopefully he can provide this. The closest we have had for a while has been edge-of-space flights(which I would love to do!).

There are no technical reasons why we can't do E2E in 30 mins. Just financial, and we have a world with more mill/billionaires than ever before.

Financial and political. Although maybe you can buy politics.

Imagine the prestige of being the first city with a BFR port?

Fuel will probably cost more than a jet bot not a lot.

As Arthur C Clarke once said of such forms of transport, half the time the toilets will be out of order and the other half the toilets will be inaccessible.

Cool. How much?

Question, if Musk succeeds with his neural lace (I hope he credits Ian M banks for that), then will there be a great need for this kind of travel?

27 minutes. Part of the pre boarding procedures lol

Can't help but think of the pollution it will generate: noise and air.

With the ticket prices serving the elite of the elite, I guess the pads are offshore just to keep the hoi polloi at bay!!!

Not much point in the being the *first* city with one

Network effects, my dear boy...

The fuel they us is RP-1
https://en.wikipedia.org/wiki/RP-1

By products - Hydrocarbon combustion produces carbon dioxide (CO2), toxic carbon monoxide (CO), hydrocarbon (HC) emissions, and oxides of nitrogen (NOx), while hydrogen (H2) reacts with oxygen (O2) to produce only water (H2O), with some unreacted H2 also released.

Cant see Sadiq Khan letting one of those near his pure and virgin London air.

The motors would only burn for around 15 minutes in total (lift off and landing). Compare that to the hours a jet plane has to burn fuel.

Other rocket motors can operate of hydrogen or methane, so reliance on RP-1 isn't compulsory. It's just easier.

Musk talks about using solar power here on earth to create methane. Trying to justify it to green peace

Once he has enough BFR's .. nothing to stop him just popping over to titan to slurp up lots of free fuel

Mars 2022: Cargo missions. "Not a typo".

[Caruso]

I wonder how the fuel consumption compares to a jet? As it is jets climb to 30,000+ ft to be able to go faster on less fuel where the air is thinner.

"but may be a little aspirational" was, I think, the next line.

BFR is slated to use the Raptor engine.; a full flow staged combustion design using methane and lox. Much less carbon.
The noise will remain an issue though.
