  1. Re:I believe solar thermal does benefit from scale on Brookings Study Calls Solar, Wind Power the Most Expensive Fossil Alternatives · · Score: 2

    Solar thermal still makes sense where the aim is to generate heat, rather than electricity. As a method of heating water (either for domestic or industrial purposes) it will always be tough to beat, boasting as it does a zero wastage conversion rate (because there is no conversion- you produce the desired end product straight away).

    An awful lot of energy is expended to produce heating, so cutting out the electrical middle-man is no bad thing. There is also no reason why you can't distribute hot water via pipes from a central solar heating installation.

That means that in 0.0001% of universes, a very smug version of me is winning a Nobel prize for proving the existence of the multiverse.

    Both wine and "ale" beers are made with saccharomyces cerevisiae yeast. Although there are different strands preferred for different styles of wine and beer, the differences shouldn't be too over the top. You're not going to end up with a fine best bitter with champagne yeast, nor are you going to get a competition-standard claret with ale yeast- but the results will be drinkable and tasty enough. See, for example, "champale" (beer brewed with champagne yeast which has been sold commercially).

    Lager is made with a different species of yeast (s. carlsbergensis). So using a wine yeast is never likely to make a decent approximation of a lager.

    As others have pointed out, you wouldn't need to describe a human to a molecular level. You could create a biological clone using just the DNA- the human genome is some 24 gigabits (3 gigabytes?). That'd be something like "a few hours" to transfer over a standard home internet connection. Arguably, there are big chunks of that genome which will be common across individuals, so you wouldn't even need to transmit the whole thing every time.

    Transferring a human's consciousness would be more difficult. As far as I'm aware, there are no serious estimates as to how "big", in bits/bytes terms, the human consciousness might be. Even if you could scan one, and it was a reasonable size for transmission, I can't even imagine how you'd go about "implanting it" into another human body (e.g. a clone). Without that, there's no "I'll just download into a Martian clone and have an explore".

    Growing clones is hardly magic (and that is all "printing humans" means in this context). We can already do it with provisos (i.e., with the right embryonic cells and so forth)- there's no reason to assume we won't learn better methods as biology progresses. Animals grow new animals in their wombs out of nothing but carbon and nutrients all the time- can't be impossible to replicate.

    The "magic" bit is transferring consciousness of one human to another human body. Nobody has the foggiest how that would work. But then, if all you wanted was a populated colony, who said you even need to do that? Grow the little humans to adulthood and raise them using robotic machines, and voila- one new colony, without the hassle of transporting 100's of humans 10's of light-years through space.

    It is disingenuous to count XP's support period from its first release date, considering that each Service Pack represented as big a change to the OS as each Ubuntu release (for example).

    Support for original XP (without a Service Pack) ended in 2005- only 4 years supported. The last Service Pack, SP3, was released in 2008- giving it a respectable 6 years supported. If XP had exited support when it was scheduled to (2012- it was only extended due to a Microsoft product-line-up cockup at the hight of the netbook craze), it would have had 4 years in support too- less than any of the others you named.

    Even if you stubbornly disagree with what I'm saying about SPs and wish to count it all the way from SP0-SP3 end of support, might I also reiterate above that support was only extended at the last minute due to a Microsoft cockup- namely, that Vista was wildly unsuited to the then very popular netbooks. The standard offer from Microsoft is 10 years support (which is what you might reasonably expect to receive from Windows 8). This is the same as Red Hat, and comparable with other Enterprise-market OSs.

    Cost of a PC monitor = the cost of a TV to use with a console. Do you count the cost of the £500 TV in your lounge when you count the cost of your PS4? In my case, I've had the same two monitors (dual screen) hooked up to my PC for around than 10 years now- and one of them was free second hand in the first place. My lounge TV, on the other hand, I chose specifically and spent good money on not so long ago.

    Cost of a router applies equally to both console and PC. Both of them need to connect to the internet, and both of them will have the same "advantage" in reduced latencies, if you're so inclined.

    So the cost of my PC which could be fairly compared to a console would be- the PC itself and all internals came to around £500. The mouse was £50, but it is getting towards 10 years old now (was a good Logitech MX518, and is still going strong). The headphones were about £7.50. I own a joystick, and although I hardly use it I'll include the cost- it was around £25, bought in an offer along with X-Wing Alliance back in 2000 or so (Microsoft Sidewinder, still works perfectly). Keyboard came bundled free with the PC case (as did a decent mouse which I don't use). So total cost- perhaps £580 or so, ignoring the fact that several peripherals have survived multiple PCs.

Every morning my uncle would go around collecting the slop buckets and take them back to the farm, where they would all be emptied into a big vat and boiled for a number of hours. The end result would be a mushy stuff with the texture and smell of vomit, but which would be sterile of any nasties that could harm the pigs. The pigs loved the stuff. Filthy buggers.

    Chucking a few jars of peanut putter into the mix every day would have been easy enough.

    Of course that wouldn't even be strictly necessary, seeing as the manufacturer of the peanut butter seems to be swearing blind that the product is uncontaminated and fit for human consumption. If the farmer were happy with this, they could go nuts and just feed it straight to the pigs.

Then the manufacturer would have been free to resell it (or donate it), and would be fully liable for any risks. It sounds like the supplier is in some financial difficulty, so would have welcomed the chance to relabel and sell it on to a different retailer. Seeing as Costco weren't willing to pay for it, I don't see what objection they should have to that- and it's not like that decision would have any impact on their competition (i.e., it's not like their competitors would have to do without peanut butter if this shipment gets destroyed).

    You've sort of hit on the problem and solution. What we need is something that is not called a "taxi" for this. Rather than taking the existing taxi system and adding ride sharing, we should supplement taxis with a new form of public transport based on this system. The new system would be somewhere between a bus and a taxi- a medium sized public vehicle (perhaps "minibus" size), but which would be summoned on demand and travel to your chosen destination like a taxi rather than travelling a fixed schedule like a bus.

    This would solve both of the obvious problems- the first being that people who order taxis expect a private vehicle taking the shortest trip possiblem and the second being that existing taxi drivers and firms don't have a pricing system that could cope with this sort of change.

    If you made the vehicles sufficiently sexy and space aged (rather than just using regular old minibuses), you could easily sell it as "the mass transit of the future". Since the vehicle wouldn't be expected to take huge numbers of people at a time (only really two or three small parties at once), you could make the insides suitably comfortable on a standard van frame.

    The US would be in no great danger if it lopped 5% off of it's military budget. You could cut the budget in half and it would still be larger than numbers 2 and 3 (China and Russia) put together. Again, not even counting NATO.

    To put figures on it- the Apollo programme was estimated to have costed $109 billion in 2010 dollar (accounting for inflation). That's for the full 15 year or so programme. The US was estimated to have spent $682 billion in 2013 on the military.
