The data collected by the "Lunar Reconnaissance Orbiter" can be used to estimate the frequency of impacts.

It truely is. I found it years ago and have used the data in various projects since then. :)

it indeed is hardly possible. See: https://www.openrailwaymap.org/

That is indeed interesting to think about. What exact mechanism did you had in mind for thermal energy transport?

correct

Next iteration of unix-time should include the concept of local time in context of relativty if we are going to travel or communicate over significant distances.

anyone throwing a party for the illuminated?

Thank you for you insight.

Can someone maybe with lab experience in propulsion or comparable knowledge confirm that their method to measure the thrust of the plasmathruster is in any way comparable to proper thrustmeasurement / produces forcevalues correlatable to those measured with an unobstructed outlet and proper equipment?

The number sold electric vehicles in germany is still exponential not saturated, the government recently announced to build additional charging stations across the country in the order of 10 thousands and to increase the (tax) incentives for hybrid and fully electric cars. It is a good time to build a factory for electric cars in germany. Berlin is a sweet spot when it comes to talent in high tech, suppliers and transport connection.

I bet elon will not be able to land in BER for the celebation of the millionth car rolled out there.

This industry needs more players to drive the price down. 400$ for extruded plastic hull, cheap electronics, a fan, a filter (and a battery pack for a mobile device) is way to much. I build one for my flat for less than 50$...

Solar and Wind are free and widely availabe primary energy sources. No infrastructure is needed to dig it/pump it up, transport it and process it befor it is usable, as with fossile fuels and nuclear power.
