I had an idea the other day of using electrolysis at the bottom of an extremely deep water filled shaft to generate gas bubbles that could be harnessed to turn turbines as they rose to the surface.
Whether that could ever be more efficient than other power generation methods I have no idea. I guess the initial construction and ongoing maintenance requirements might make it not cost efficient. It was a fun idea to think about though!
There was an interesting recent book that covers a lot of privacy vs technology concepts that are increasingly relevant. I'd highly recommend checking it out. It's a quick read.
The use of margin debt to trade mainland shares has climbed to all-time highs, while investors are opening stock accounts at a record pace. More than two-thirds of new investors have never attended or graduated from high school, according to a survey by China’s Southwestern University of Finance and Economics.
I strongly dislike Marvel movies. I have no respect at all for films that are released in 3D (and sometimes IMAX and IMAX 3D) when they are not filmed in 3D or using IMAX cameras. It is a pure money grab. Disney does not care about quality, they care about profits. The endless sequels and prequels and spinoffs are simply greed. They will not withstand the test of time. A decade or two from now, people will look back at Nolan's Batman series as the definitive super hero films of the day. They use real sets and stunts instead of endless poor quality CGI action scenes that move too fast for you to see what is even happening (hint: it's because what's happening is meaningless, but bright colors and fast movement stimulate your brain). Marvel exists to sell children disposable plastic action figures and made in China clothing that will fall apart before the next sequel comes out.
Children are marketed to and manipulated with cartoons and "happy meal" toys. It is insidious.
On top of that, Disney expends a tremendous amount of money on marketing to force their products into the prevailing culture. Have you noticed how many television shows have references to Marvel super heroes? Those jokes aren't because the writers are fans, Disney pays for them. Actors don't wear super hero t-shirts randomly. It's all marketing.
They are doing the same thing with Star Wars. There has been an insane amount of hype for the new movie and various spinoff products already. Quite frankly I am sick of it. I am not going to see the new Star Wars movie in theaters because this type of behavior should not be rewarded.
Disney buys up treasured parts of global culture and exploits them to death. It was heart breaking to see them do this to Pixar. Cars 2, Monsters University... just shameful cash ins.
The train of thought that has me leaning towards becoming vegetarian is along the lines of:
If an advanced alien species came to Earth, how would I want them to treat humans? How about in the case that they are advanced to a level that comparing their abilities and technology to humans would be the same as comparing human technology and abilities to that of birds or dogs or cows?
Would I want them to dismiss our primitive (from their perspective) nests as the work of an unintelligent beast? Would I want them to corral us into pens and feed us fattening foods before harvesting our bodies? Would I want them to feed us hormones and genetically modify our bodies to produce more milk or grow larger muscles for consumption? Would I want them to breed the outliers of our species to create extremely large and extremely small "pure-breeds" of humans as a novelty? Would I want them to dismiss our primitive verbal communication as nothing more than cheerful song and make no attempt at all to understand what we are trying to express?
With 80%+ of corn grown in the US being from Monsanto seeds, you can bet that there is going to be a lot of push back against this. Why are taxpayers subsidizing an already profitable industry? How many millions does Monsanto spend on lobbying every year?
That article has a lot of fear mongering about artificial sweeteners and then at the bottom an ad for "certifiedorganicevaporatedcanejuice.com". Maybe it's not the most objective source of information?
Every news source is biased. Your job is to understand what that bias is and compensate. By following multiple news sources with different bias you can discern somewhat the truth of matters is as it lies somewhere in the center. Some outlets are more predictably and openly biased towards one direction.
I think bitcoin will be incredibly useful in the digital goods economy. Global digital marketplaces need payment solutions that transcend nationalities. If you create an album of music and want to sell digital copies online you should be able to accept payments from customers anywhere in the world using any currency. Bitcoin allows that to happen. If you want to create a video content channel and let people pay a monthly subscription there should not be any type of restriction because of what country the viewer lives in. All of these borders and constraints are artificial and unnecessary in a digital economy. If you want to create a digital service that operates entirely on the internet, why should you be restricted to using a subset of currencies? Bitcoin can be the transaction layer that makes all the human constraints irrelevant. Digital goods also offer essentially no cost of replication so the only real limitation on the size of the digital economy is the number of agents participating in it, which increases daily. The tools needed to create and consume digital products are becoming cheaper every year and more people are gaining access to them globally. IMO the future of the world economy is going to be increasingly digital, and increasingly created by independent producers. Games, books, education, movies, short format shows, PC and mobile applications, web services, photography, art, comics, all will be available to anyone in the world at very low cost and with no necessity for restriction. As I see it the only thing holding back this digital revolution is that consumers are largely ignorant as to it's existence and continue to support antiquated development and delivery systems. I do not think that the rising young generations have this impediment in their habits. What really seems to be missing is a global system for independent content discovery. I'd like to see a universal amazon style digital product aggregation and distribution system that only uses digital currency. The store would provide discovery and distribution (maybe digital currency exchange as well) to a global audience for a transaction fee that beats traditional payment methods. A wiki style product information page that allows users to provide additional product details and translations for localization would be interesting to see (while difficult to moderate).
tl;dr with bitcoin anyone in the world can create a digital product with nearly zero replication or distribution costs and sell it to anyone else in the world basically instantly. That infrastructure exists today but is underutilized.
The progressive faction of the Democratic party is pretty close to what you're looking for. Check out Elizabeth Warren.
Young people could have a lot of say, but they don't vote. The national dialog would shift a lot (IMO) if young people educated themselves on issues, got their peers to engage in discussion, and participated in the political process especially by voting. Right now politicians that pander to the majority do so to the people that show up to vote, which is older people.
I already do feel that way regarding technology (and consumerism in general). I think that by supporting FOSS such as Linux and the Mozilla backed projects you can vote for variety and innovation with both your time and money. I will happily switch from an iPhone to a Firefox OS based phone once a high end model is available.
There are actually a lot of smaller companies making craft sodas that are of a superior quality to the mainstream brands. They typically use cane sugar instead of high fructose corn syrup, and come in a wider variety of flavors. Plain cola gets boring fast. I much prefer cream sodas and birch or root beers. Here are some examples:
Personally, I never drink Coke, Pepsi or Dr Pepper products any more. A large part of the cost of those products is relentless marketing, shareholder dividends, and large corporate salaries. They no longer seem to care about delivering a quality product. How can they sell something called ginger ale if it doesn't actually have any ginger? For variety and depth of flavor any money I spend on soda is spent on craft soda.
Whether that could ever be more efficient than other power generation methods I have no idea. I guess the initial construction and ongoing maintenance requirements might make it not cost efficient. It was a fun idea to think about though!
