Yeah 2k2k was standard even back in the 1990s on Eurocat using CRTs. I am a bit surprised they haven't gone beyond it now though, given what can be done with LCD.

Its a mototcycle. Where I live the limit is 200 watts. Less than that and your vehicle is a bicycle regardless of the number of wheels it has. I suspect this engine puts out a lot more than 200W.

I thought maybe the reader can tell the card give me 10^6 Zimbabwe dollars, and then tells the back end card has agreed to 10^6 UK pounds.

I looks like the hybrid solid/liquid engine isn't going to push SS2 to 100km altitude. The original compound ran rough and it doesn't have a high enough specific impulse. The new compound explodes. Dick Rutan demonstrated a Long-EZ equipped with a liquid fueled engine in 2001. I think it is time to go back to XCOR and ask about a bigger engine.

The Guardian article says this was actually the first flight test of the new plastic based engine. So I suppose it worked for a few seconds in flight, nothing more.

Frame 2 from the ground based photos seems to show that thrust from the engine reduced before the explosion. I wonder if something came loose and obstructed the outlet of the engine, causing an increase in pressure. Sort of a blowback situation.

Consistency is a big issues with solid fuels. The shuttle SRBs were paired during construction, and the fuel was poured at the same rate into each engine from the same source. That way if the engine developed more or less thrust because of a variation in the consistency of the solid fuel, it would happen on both sides of the shuttle. Liquid fuels mix themselves, but a mixing problem is locked in to solid fuels until you burn them. I just wonder if a mistake was made during construction which caused a sudden increase in engine pressure, above that caused by the greater efficiency of this new fuel.

There is one switch in the US which will disable the whole system. GPS works badly for aircraft because they change altitude. Most users have a fixed altitude, so a small degradation in the system can cause large positional errors.

Its used in Australia as well, in parallel with GPS and radar. The aircraft transmits a signal, and multiple ground stations compare the arrival time.

It looks like an INI file for describing different layers in windows.

Can we still slashdot things?

I had the impression the Model S has two motors between the rear wheels, one for each wheel.

Its hard to miss. Basically a wall from the Arctic to the Antarctic.

He doesn't mention Chinese tea houses. Tea has been important in China for thousands of years but Polo makes no mention of it.

It made the jump because of the large local population, fed by modern transportation systems. Previously it hadn't been possible to support a million people in such a small area.
