Yes, amazing. The restaurant looks REALLY nice. Singapore is starting to look really nice -- maybe I should visit? Sure, the chef is amazing. I'm surprised his wok does not have a long handle. So, he uses a towel as a pot holder whe

Wok? Gas heat? Enough heat? Okay: (1) Off the kitchen, have a back porch, i.e., no roof, call it a deck . (2) Get an inexpensive, propane powered deep fat fryer turkey cooker. (3) Use the propane burner to heat a wok. Get plenty of heat

Yup, would be terrific if humans could be productive and meet the needs you have described. Sorry, humans can't do that. We can transmit some orders to some robots, have them work for some hours, usually longer, and then transmit the

Cremation, burial, they sound like you are assuming some colonization. Well, there won't be any colonization -- humans just can't hope to be in space very long without serious harm from low gravity and high energy cosmic rays. Yo

That they die is not so embarrassing. Instead when they die, in practice they will freeze (it's cold out there) and, due to the high expense of any alternative, just accumulate, pile up, frozen and stay visible for 1000+ years.

Nope. Doesn't follow. Instead, we get to bury our dead, and they quickly decompose and can be forgotten about. In strong contrast, on the moon or Mars, burial would be wildly expensive, and the bodies would remain frozen and last fo

How? The person is, uh, did I mention, dead? Since our intention was not to send people out there to die, their death indicates a failure, and that is an embarrassment. If anyone is a little slow to see the embarrassment, then I'm su

If we, the US and/or EU, send humans to the moon and Mars, soon we will have humans, maybe a lot of humans, dead on the moon or Mars or floating in space, for maybe some thousands of years. Big, long term embarrassment. Not good. Thu
