esemor | 4 years ago | on: Every euro invested in nuclear power makes the climate crisis worse

I find the efficiency angle of his argument to hold some merit but as I scan the article I cannot find anything about how to solve grid fluctuations. In my home country of Sweden, solarpanels are not a viable suloution in the northern part of the country as moste of the energy i used for heating in the winter when the sun don’t shine.

I (an Apple fan) do not consider this a failure. I love it when companies take chances and go all in on pushing the envelope. Great products do emerge from these sorts of products.

Near my house there is what you could call a insect ”sanctuary”. When it was established a few tears ago we kind of shrug our shoulders and did not think much of it. But the amount of new flowers and insects popping up, not only inside but also around the area is astonishing.

I almost see it as a positive feedback loop with more insects, better pollination, more diverse flowers, more insects...

Just as pesticides could create a negative feedback loop.

It is perfectly rational to be scared of flying. Hell, you're sitting in a pressurized cylinder at 30'000 ft flying at 700 mph. But you have to realize that the crew would not do this job if they weren't sure to come home to their families and dogs every night. Most pilots I know aren't thrill seekers but their love of flying are more a drive due to interest in travel and technology.

I think the auto shutdown of engines in flight, in case it senses reverse thrust, is a great design.

The 787 is a replacement for my 767 (currently a pilot on the aircraft) and in 1991 a Lauda Air 767 suffered a failure in one of its thrust reverser and it became activated during cruise. The aircraft was destroyed in flight.

The thrust reversers should not activate during flight (a air/ground sensors prevents that) but as it is a catastrophic failure, having the engine shut down automatically seems like a great fail safe device.

In this case it seems that the 787 engines were reversed before the air/ground sensor had sensed ground and it is a potential problem.

esemor | 9 years ago | on: Engineer defends concept circular runway idea

You never land with a tailwind and if the wind shifts the airport simply change the runway to the opposite one. If you use a circular runway and landing with a cross wind you would during your landing roll be subjected to a tailwind.

Sure, you could stop using that part of the runway but then we're back at the practical economical argument for this design.
