And drugs!

I´m long on Tesla, have an average buy price of 220€, with some lots around 170€. Valuation seems crazy if you compare to GM and Ford, but those are low margin car manufacturers. Comparing with Mercedes or BMW, and considering sales values in 2021 and 2022, the valuation seems right. Considering the long run, plus autonomous driving, plus energy sector, Tesla can go up 4x easily.

Not really. Business in Asia is handled like in southern europe: decisions are made while eating and drinking. This establishes a trust bond. Also technical discussions, training, troubleshooting have to be done in loco. Not to mention that in many companies it is forbidden any type of outside access without being there. All my trips to Asia were like that: I could not even bring a watch or a pen inside!

Should have added the <sarcasm> to it. Thing is, you can cross the atlantic for free, but you have to help out as a sailor, which means an experienced sailor doing long hours, which she didn´t.   My complain about it was that she crossed the Atlantic on a very expensive catamaran, to avoid air travel, like if the common mortal could do the same.

Should be rich, crossing the Atlantic on a sailboat is not accessible to everyone. And the Spanish offered her a donkey to travel from Lisbon to Madrid and she refused, so definitely rich.

It's a sign of isolation when everyone around you sounds the same

They will become much cheaper within 1.5 years. Tesla will begin producing their own batteries in 2020. Then in 2021 the Tesla European factory in Berlin should drop the prices even further. Right now they are expensive simply because of demand.

Sorry, my math was for Portugal... I won't invest in a house which is not mine, in Germany...    

  You are mixing W with Wh. BTW 5KWh is enough for my daily commute. Although I would probably install 2kW solar panels, to get around 20kWh per day or more. Enough for self consumption, plus car, plus heat pump.      

If you fly to asia in first class, you pay upward of 8000€ and the flight is slow. But people still pay for it. There is a huge wealthy market out there, for intercontinental flights. Also a large market for executive flights. An executive for a large company can cost easily more than 1000€ per hour in salary alone. A hotel night probably 400€. Shaving 6h from a flight, plus avoiding one night stay pays a Concord ticket.

Concorde was still a good solution, it was profitable when it was decommissioned. In the next 10 years you will see it coming back.

In 2015 Portugal introduced a law to regulate self production. Up to 1500W max, nothing has to be done. Above that, you need an inspection from authorities and then the law is not clear, but you might have to pay (!!!!!) the state for energy that you produce. Of course if this is happening inside your house, you can tell them to fuck off easily. They will try, they will get something out of it, but inside the house it is really hard to control. They could measure the area of solar panels on the roof, but high end installations are already using solar tiles, which you cannot distinguish from normal tiles. Then there is the legality of taxing what you are self producing, I think this would not hold in EU court.

There will always be a minimum of grid energy, but you will see many companies and houses become independent. The big paradigm shift is that you don´t need huge power plants any longer. Small scale wind/solar/hydro plants, coupled with batteries, will completely disrupt the energy market, kill most of the old power plants (especially coal and gas) and lower the prices.

NASA had the same original idea, but by the end of development, the stupid wings were already so big that they could just glide. And that is the biggest criticism of the whole project: the wings became monster because the air force requested a large cross range, for a special type of launch that was never done!   They should have stuck with Saturn V for lifting cargo and then have a mini-shuttle for astronauts. Alternatively, they should have gone with one of the original plans: 2 stage system, first stage flies back to base. First stage is RP1, not hydrogen. 2nd stage is either full hydrazine (simplicity) or a low thrust hydrogen (smaller engines, high performance) with multiple start capability and hydrazine's role is reduced.

Antennas don't make much shade on the solar panels, you can cover the whole roof. Of course a thin tall building won't be able to produce much, unless you start placing them on the south facade.
