Comment Re:Protein from plants, not animals (Score 2, Insightful) 381

Sorry, you are abusing the statistics a little here. Plants have high protein % as total calories - because plants have ridiculously low calories to begin with. On the other hand, ground beef provides 38% of calories from protein - because the fat is much richer source of calories to begin with. A more useful statistic for you to consider is grams of protein per 100g serving of the said food.

Lettuce - 1.35g protein / 100g;
Broccoli - 2.8g protein / 100g;

Dried legumes have higher proteins. Keyword: Dried.

Lentil - 26g protein / 100g;
Soy beans - 36g protein / 100g;

Still, meat provides higher protein at higher bioavailability:

Beef, 15% fat - 26g / 100g;
Dried beef (jerky): up to 65g / 100g;
Salmon - 20g protein / 100g.

There is no point in arguing. On a per-gram basis, meats provides much higher protein % than plants. If you want to use protein calorie % as your metric, you can eat meat moderately - or eat a shitlaod and shitload of veggies.

Grain & Cane are not food for people.

There are about 15 starchy plants that provides about 90% of all caloric intakes for human around the world. Perhaps if you didn't abuse the caloric consumption, you would not have had the problem today. Besides, what is your food intake like now? Do you think it's feasible to push your diet to the population around the world?

Perhaps, instead of blaming grains, sugars, and carbohydrates, you should look at your own overconsumption / under exercise as the key culprit as a cause for the variety of problems you are facing. I can point out so many cultures that primarily consumes a grain-based staple diet with long expectancy. I challenge you to provide me with example of a culture / subculture that lives to above-average life expectancy with low health problem that is heavily based on a meat-based diet.

Comment Her numbers don't make sense. 20mil companies?! (Score 2) 271

How did she manage to dig out 20-million US-based companies?

 
Doesn't this number feel a bit mind boggling for you, consider the entire eligible work force of the U.S. is only about 188 million? In other words, about 1 in 10 of the population within the U.S. owns a business.

 
Turns out that the total number of business registered in the U.S. is only 7.4mil in 2010 (http://www.reuters.com/article/2012/06/26/us-usa-economy-businesses-idUSBRE85P0X720120626).

 
If she is a VP at a company that does marketing, and she can't even properly size her market... perhaps that's why they went bankrupt.

Messed up my formatting.

Note: I am speaking as a material engineer who spent about 6 years in R&D for the 65W LED bulbs you can now buy at HomeDepot. The articled failed to mention the most important aspects of the LED manufacturing: wafering and the MOCVD that deposits the light emitting materials (the PN junction) onto the wafer. In short, the steps would include:

1) Crystal growth / wafering / surface prep; (make the wafer)
2) Nitrite epitaxial growth; (grow the light emitting part)
3) Wafer fabrication (cut big wafers down to die-sized chunks)
4) Packaging and testing (encapsulating the die) -- what the article was describing

The article only touched upon the 4th step of LED manufacturing, and concidently, the most automated aspect of manufacturing, as well as the part that contains the least amount of patents / trade secrets. The first 3 steps were marginalized as "This is a sheet of LED dies. YunSun buys their dies from a high quality Taiwanese company". To my knowledge, there is no high quality manufacturer in Asia outside of Japan. Samsung makes a great quantity of ok stuff, and China / Taiwan makes a great quantity of shitty stuff that is ruining the entire high profit margin products. Also, all of the major manufacturers of LED dies dare not introduce step (2) and (3) into China / Taiwan due to IP issues.

Wafering is important because larger wafer sizes (2in to 4in to 6in) means more dies per area. However, crystal quality becomes harder to control as sizes go up, especially for US-based LED manufacturers that is based on silicon carbide instead of sapphire. The real issue is with the MOCVD, the deposition technique that grows the PN junction which actually emits light. In the world of deposition, MOCVD is archaic voodoo magic and we spent a lot of time praying to deities of deposition that our process would repeat for more than a day. Fab is more systematic than epitaxial growth, and the real science here has to do with light extraction. Again, big money is spent on R&D here, and we dare not bring the manufacturing process to Asia (except for Japan).

First, LEDs are not grown on silicon. Most of the manufacturers in the world is based on sapphire wafers, and some U.S. based manufactures use SiC wafers.
Second, consider the physics of LED: you have a lot more control over current spread and light extraction if each die is individually treated.
Third, think of extra manufacturing technical difficulties as you saw through layers of different materials, each with different thermo and tensile properties.

Comment Re:Bike lanes... (Score 1) 947

Yeah, I live in Vancouver too, and cyclists are absolute pests. Their behavior is absolutely unacceptable. For longer commutes I drive, for within downtown I walk. As a pedestrian, I almost constantly get runover by cyclists. They are loud and rude. Constantly screaming, "walk faster!" "Don't walk during rush hour!" "Walk further to the right!" If I'm driving, they are constantly wavering in and out of traffic. Rush hour and they will ride single file on Georgia. In the passing lane. Two cyclists will take up both lane on Kingsway, holding up 2, 3 blocks of traffic. Soo... my conclusion is that cyclists really aren't concerned with overall traffic condition, they are only snob about self-satisfactions and filling their own insecurity need of "doing something for the environment". They do not benefit the traffic situation as a whole. Get ride of these damned pests and Vancouver will be a better place to live in.
