Kite-Powered Ship Launched
The Grand Poobah writes "The big-kite technology we discussed last month has officially launched in Hamburg, Germany. Reuters has a writeup of the new technology, which aims to cut fossil fuel use on sea voyages by an estimated 20% by means of a huge computer-controlled kite. The link includes a video."
- it can be used at these cargo ships normal cruise speed,
- it saves the shipping company $1600 per day
- and it utilizes higher altitude winds,
I would say they have succeeded.For the perfect anti-Unix, write an OS that thinks it knows what you're doing better than you do and let it be wrong.
Sometimes, it seems, there are no new ideas. As others have said, what we have here is a glorified sail. Nothing wrong with that, but as fossil fuels become more expensive, we'll find more and more "old tech" make a comeback.
The biggest deal in alternative energy right now is the windmill, which have been used for what, 1,200 years? Now we have a (gasp!) sailing ship! Pretty soon we'll go back to using the electric car which was very popular in the early days of the automobile.
No, basic technologies are not new - what's new are refinements. For example, Linux is a re-implementation of a 35 year old Operating System having the chief innovation of a license change. I'm not knocking the quality that Linus has put into the Linux kernel, but Linux is written to be POSIX compliant, so while drivers are nice, Linux is basically no different than any other UNIX but for the license difference.
Innovation can come from some incredibly low-tech, unlikely places. For example, this guy has won numerous awards for sticking a pot inside a pot and filling the middle with wet sand - managing to solve a serious problem in Africa for low-cost refrigeration.
I guess what it comes down to is this: Technology is valuable when it works, not when it's complex. There's lots of very, very, very simple technology that nonetheless works very, very, very well.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
How long do you think the life of an average cargo ship is?
$725,000 / $1600 per day gives about 450 days before break-even.
Ships have a useful life of 20 to 30 years, so in the end, you wind up about 12 or 13 million ahead, even factoring in a total replacement at mid-life. And this rough calculation is just at (presumably) todays oil prices - when oil is double the price, you're now saving $3200/day and so on.
Plenty of scope for some serious cost savings.
You are in a twisty maze of processor lines, all alike.
There is a lot of hype here.
Hello. Do you know any actual humans? Here's something to ponder: economic interdependance and global trade is the most effective way to prevent war. If you stop trading, then your neighbour may decide to just come and take your resources.
