  1. Re:Photosynthetic efficiency vs Photovoltaic effic on New Study Says Governments Should Ditch Reliance On Biofuels · · Score: 1

    I think transportation except for airplanes and hot air balloons will switch to electricity power. I think solar cells have far more potential than biofuels for optimized output as well much lower operating costs. Long term biofuel seems like a waste of time.

  2. Photosynthetic efficiency vs Photovoltaic efficien on New Study Says Governments Should Ditch Reliance On Biofuels · · Score: 2

    I've been suspicious of biofuels for quite a few reasons, but mostly due to efficiency. According to the numbers I saw photosynthetic efficiency is 3-6% but .photovoltaic are 30+%. So covering a field with solar cells would be 10x more efficient than harvesting biofuel from the same field. Don't flame me if I'm comparing apples and oranges, I have done a bit of googling on the subject and not really found much.

  3. what does your polluted river have to do with... on US Senate Set To Vote On Whether Climate Change Is a Hoax · · Score: 1

    its an analogy. sorry for thinking so abstractly. dumping coal tailings in a river is a regional pollution problem. dumping carbon dioxide in the atmosphere is a global pollution problem. its called an cost externalizing. In the case of the river pollution there were multiple groups suing the polluters and litigation was becoming potentially very expensive. it was one of the causes of the federal government creating the clean water act. Regulation has been very effective at cleaning up the rivers. The poster I was responding to called it 'socialist authoritarian solutions'. I'm just saying that policy is effective sometimes. Its probably what will need to happed with polluting the atmosphere with co2 because private industry will not voluntarily address the problem.

  5. Re:denial as a negotiation tactic on US Senate Set To Vote On Whether Climate Change Is a Hoax · · Score: 1

    I lived near the Susquehanna in central PA before the clean water act (CWA) was passed. the coal mine processors flushed water from the cleaning processes directly in the river at multiple locations. there was so much coal in the river that a new business was created just for dredging it off the river bed. By the 1960s the mine owners were being sued by multiple groups to stop. The Cuyahoga, (OH) river was on fire because many times because refineries were dumping directly in the river. one of the fires damaged a railroad bridge and the railroad was suing the refineries. The clean water act was passed because the court system could have been choked with legal fights so the federal government passed the regulation. I would love to hear how the court system will work in a libertarian dream land without any regulations like CWA, or as you call it like, 'socialist authoritarian solutions'.

    personally I believe that republicans don't like climate change because it doesn't fit in their neat little world view of libertarianism and markets. I think they are denying the problem until they can come up with a solution that involves some kind of subscription model or something. if you want decent weather you will need to pay for it. as soon as they figure out a way to make a profit from it, it will be the highest priority ever

    look at the comment sections for the 3rd party keyboards for iphones. there are a lot of ex blackberry owners frantically looking for a decent keyboard for an iphone. doesn't help that the form factor of the iphone keeps changing and the keyboard selection changes for each one.

    maybe Samsung will get blueprints to a decent keyboard. I can't believe how all the handset makers dropped the built in keyboards. I've tired some of the 3rd party keyboards and they are crap. the two I tired didn't even have the f and j keys marked. I marked them my self with some epoxy. just as I got used to them, they batteries died and they wouldn't recharge. I'm not particularly happy with blue tooth either, too slow. an addon keyboard that plugs physically into the phone would make me very happy.

  15. Re:History Channel - Real History costs too much. on Finding Genghis Khan's Tomb From Space · · Score: 2

    BBC always had some good documentaries. I (usa) have been watching quite a few lately about WWI and WW2 east front on Youtube. they are mostly low res standard format, but good enough for me. ( I don't know the provenance of the shows are..). History channel used to run quite a few BBC shows about middle ages that were pretty good. but since about 4years ago I haven't seen anything on usa channels from BBC. can anyone from uk comment on recent material? History channel does have some problems with documentaries set in the prephotography era. the choices are talking heads, dramatizations, slow panning shots of ancient ruins and artwork or cgi. some of the cgi shows like engineering an empire and lost worlds, and decisive battles are great. But I suspect they were expensive and only some material really works well that way. Personally I suspect that when the tv format went wide screen and hi res, history channel choked at the expense of refilming the material in the new format and decided to go with cheaper reality shows until they can figure out ways to film real history shows cost effectively.

  16. Internet, Youtube etc great source of repair info on Professor: Young People Are "Lost Generation" Who Can No Longer Fix Gadgets · · Score: 1

    The internet is providing a real renaissance for repair info for me. I have a sailboat and learned quite a bit about working with epoxy on various internet sites. on my house there is wood exposed in a few places. I've been treating them with epoxy and they are holding up quite well now. At work we have quite a few printers, I told purchasing don't buy any more printers unless they have unjamming instructions are on youtube or somewhere else online. my brother has a farm. he's a pretty good manager and excellent repairer. of 150 farms in one study his income over cost was the best rated because he has so few repair bills. One time he needed to replace cogs on a his older combine. new from mfg would have been 500ea. he found on the internet the right ones (for 50$) but the shaft was wrong. between him and a friend they cut the shaft part out and swapped them. Saved a couple grand on the upgrade without too much extra work. My general rule of thumb, i will repair my self if i can extend the life of the product a few years if the cost is cheap even if the item looks weird and was obviously repaired. I will improvise a repair job as long as its safe and i can do for 20% or less of the cost of the correct repair method. if my improvised repair doesn't work I'm not out too much money.

    There is a problem with public policy. even though the overall group could be better off because of government intervention, there still could be sub groups of winners and losers. I think that a lot of the deniers will only admit there is a problem when they are sure the solution does not make them a loser. So it could be beneficial to start implementing solutions and see which one get shot down because these 'denegotiators' think the cost is to high to their group.

    I agree with parent. PETA thinks: 1. Domesticated animals are exploited by people so domesticated animals shouldn't exist anymore. 2. Pets need a health care plan that rivals human health care, so nobody can afford a pet anymore. 3. Nature with its predators and parasites is so cruel that wilderness should be eliminated too. They've been talking about eliminating the horse drawn carriages in NY central park and replacing them with electric cars because 2 horses have been involved in traffic accidents in the last 30 years. The horses will be sent upstate and live out retirement just grazing in a pasture. But that's not without danger either. they could bet bit by snakes, hit by lightning, or break a leg in a gopher hole. To eliminate all suffering, its better if they just euthanize the horses now.

    It does have some issue with contrast and refresh, but its still very impressive. the 28" Samsung could be a better deal now.
    Some observations.
    1. Youtube has quite a bit of 4k content. however you need a 15-50Mbps connection, mine is a 6Mbps Verizon dsl line so I get quite a bit of buffering. I can download the videos and they are impressive, however, I think you need at least a 60in monitor to appreciate the difference. I've switched my video mode to 1080p and I can see some difference in fine, curved lines, but that's about it. The photos I take with my digital camera look really good on the monitor, but mostly because its so big. If there is text in the picture its easier to read at 4k, but the picture looks almost the same if I set it down to 1080p. The monitor has made me realize I need to upgrade to a DSLR camera.
    2. At 2k it is really awesome at displaying text. the 39" is a bit too big, I have to move my head around to see where I'm clicking, but I do program on it and I have ways around that problem.
    3. I do watch a lot of nature show on my HD tv. I've been underwhelmed with the video quality of things like tree leaves, fire, flocks of birds flying, ocean waves and water splashing, groups of people or animals running. I'm hoping to see some 4k content of those things and compare to 2k
    4. I am watching the pricing on 4k projectors. they are about 5grand right now which is pretty good. not long ago 2k projectors where 3grand. a 4K projector displaying a 120" picture should look incredible. I have a place already picked out to put it in my house.

    I would say we have very different views of short and long term. The instant the tribes men that own the elephants or the fishermen who own the fish have the access to gmo versions of elephants or fish they will replace the old with the new. The long term goal of privatization is to maximize ROI. Privatization might work as a stop gap but its not going to save the natural world as we know it.

    I'm skeptical that the 'tragedy of the commons' is solvable with privatization. If somebody owned the land and was trying to maximize output, they would probably kill all the birds and raise yams or something that had a better ROI. Mankind needs to come up with some better policies on what the planet should look like in the future. I've heard the author talking about the 6th extinction quite a bit in the media lately. They have talked indirectly about extinction triage, and it needs to be addressed more practically. I propose that organisms involved in the oxygen replenishment system get top priority.
