  1. Re:Hardly a new idea on Ocean Energy Tech To Be Tested Off Australian Coast · · Score: 1

    I don't doubt it's possible. You could build one of these in your back yard with some 50 gallon drums, 100 lbs of steel and hydraulic parts off the shelf. The problem is scale and corrosion. The only two things that move underwater and doesn't need yearly replacement are propellers and fish. Even when they drill for oil, they keep the moving bits above water, even 50 years later. Immersing moving bits of metal in the water, particularly sea water is something humanity hasn't been able to solve without throwing lots of money at the materials bill for 100 years.

    Agreed, the mechanical problem is something that could have resolved in the 1880s. It's the fact that you're immersing these in a solution that is 3.5% salt, and then moving them through a 45 degree arc every 10-15 seconds. Corrosion is going to be a huge problem, and those hydraulic cylinders are going to wear out pretty quickly. Material science can probably fix that, but to make cheap, green power you need to build things not made from unobtanium.
     
    Perhaps if the generator were integrated better in to the system, this would look more likely, but the modular design has be skeptical.

    That's an interesting question! People regularly throw around the number 40 as being the minimum number of people to keep a diverse gene pool going, could that roughly be true for mammoths too? Could they splice in enough genetic material from other partial strands of mammoth DNA to get 40 complete, but slightly different mammoths cloned and breeding? And second, where are you going to find enough space and money to house your herd of mammoth mammoths?

    Well the problem with this "$1.50 refund" is that it's actually $1.50 off your next purchase with ticketmaster".

    Read them email to the end. I got this email a few days ago, and as far as I can tell this is legalized highway robbery. For the low, low price of $16.5 million to the lawyers who took up the cause, Ticketmaster gets free publicity and additional repeat customers, while not having to pay their customers anything. There is so absolutely little for the average customer to have gained from this, there might have not even been a lawsuit to begin with.

    These sorts of cases where the lawyers representing the public are well compensated need to require that a cash payment be put in to a fund to be claimed against. Reading that email from Ticketmaster was a waste of my time.

    If you run a business that is at a location that can't accept UPS or FedEx deliveries, I sure hope you'd have some sort of courier arrangement (Like a PO Box, or MailBoxes Etc) setup! Hundreds of years ago people would put mail in bags on ships set for the other side of the ocean - a surprising amount of it found it's way to it's recipient. While I agree we probably do need a once or twice weekly mail system, the world would not collapse if the post office stopped 6 day a week service tomorrow.

    Considering the condition Social Security is in, it seems to wise to plan ahead like that. Social security as we know it will be gone, or severely neutered by the time I reach retirement age.

    The last 10 non-bill mail I recieved were wedding invitations and birthday cards. It's trivially easy to find someone on facebook or similar and email them. I can't imagine why I would write a letter these days except for the novelty of it - in which case it's generally not time sensitive. It's not like people are writing to their doctor for twice weekly consultations on their condition and expect a response by mail.
     
    It's been proven for at least a decade that if you absolutely, positively need it there tomorrow, people are willing to pay $13-25 to make sure it gets there through carriers like UPS and FedEx.
     
    It's worth pointing out - kudos to the US Postal system for not taking taxpayer money to prop up a self-admitted outdated business model. It's sad to see those jobs disappear, but it's a real mark of leadership that they are taking initiative and solving their own problems. I wish the same could be said for other parts of our government.

    That's probably not too far from the truth. Someone in marketing probably thought transistor count was a statistic you could fudge, like contrast ration (10,000,000,000:1 contrast ration display! wowie! .... from grey to dark grey). Once a number is checked out by the guy in charge of things (probably new due to the recent PR flush) it gets passed around as a word doc or pdf of bullet talking points or specs and printed on fancy glossy paper by people who don't understand computers much beyond photoshop and indesign :) I did quite a bit of marketing and had to call vendors and confirm a lot of the bogus specs that had been passed around for a while and fudged from the original specs.

    Freedom used to be a lot cheaper. You can grow a full replacement army of humans every 15-20 years, but Tanks, Jets, Bombers, Aircraft Carriers etc have to be purchased with Gold and Gold Equivalents.

    I know that quakecon (about 3000 pcs + displays) brings in multiple generators on semi trucks. All the computers are run from diesel generators that are brought in from offsite, and the only grid power being used is for the air conditioning and the lighting of the building. The odd thing is that a modern 24" display draws about 1.5 amps, roughly what your computer draws. Even a "phat gaming rig" with dual video cards only pulls about 550 watts/1.2 amps while running the water cooler pump and spinning forty 30mm multi-color LED fans. Most 1000w power supplies are only running at 50% capacity, which means they are only working about about 60-70% efficiency, where a properly sized 600w power supply would be running at 80-90% efficiency.
