No, adding friends is opt-in, but they changed what information is shared with friends, and that change was opt-out and done without notice.
This mission is part of a program that is all about low-cost projects that are willing to take on more risk. The total cost of the mission was $80 million including $20 million for launch. A Falcon 9 launch costs around $70 million, which would have been more expensive than all the other hardware and operations costs combined. So if it works NASA get a great bargain, and whether it works or not they are helping develop competition in the launch market.
The first and third steps could use a closed loop heat exchanger so you're not just wasting the heat extracted in step three, but it adds more complexity to developing a solution that's commercially viable. Plus, thermal stresses would be significant for a ceramic material that's cycling rapidly between say 90F in step 2 and 0F in step 4.
I hope it works. A/C is a huge energy sink that's only growing.
And how is that? DMX is used in commercial buildings and places that have complex lighting set ups.
I go to sell my house, and the elderly couple willing to pay cash look in the server closet, realize it's a necessity for controlling the lights, rip up their earnest money check and leave.
I go to sell my house and realize the extra $50k I spent on commercial-grade wiring, DMX controllers, and lights is all sunk cost that I'll never recover.
People expect residential goods in their residences. The likelyhood that you'll find a buyer that is as excited as you were to rewire your entire house for DMX lighting is next to nil.
Local control and the "Luddite father-in-law test" are key criteria for me when evaluating a potential HA product. In the USA, UL-certification and fire insurance clarity are a close second.
So the moral of the story is early buyers will pay full price while getting a buggy, unbalanced, unfinished product. Meanwhile, those who wait will generally get discounts, see fewer bugs, and more polished content.
This is why I almost never buy anything as soon as it's released.
Also not (necessarily) true. Dissolved CO2 can be consumed by algae and seagrasses in the ocean, converting it to biomass -- where carbon remains largely sequestered when the organism dies -- and oxygen.
