Uber for everything: another form of Datong social


Human desires are unlimited. Compared to 100 years ago, our items have been around doubling itself, many of the new items which we live by every day, such networks. Now let you quit, say, those people have had no network is not very good, you certainly satisfied. On-demand service is the future of the Internet.

Secondly, the shared model more in line with the interests of humanity as a whole. From the perspective of long-term, compared to material resources, energy is relatively more abundant. Short term can not be human interstellar expansion, but this century is likely to occur once the energy revolution, energy supply will be relatively abundant. Until then, do a drill, multi-point energy consumed to supply the needs of 1,000 people, far more to do 1000 Drill sell these people are more cost-effective. Because precious metal constitute drill these materials.

Sharing Economy (sharing economic), or on-demand services (On-demand service), represents a new way to trade, to refresh our understanding of ownership. Long ago, the raw material scarcity society, private property does not exist, all the items within the clan are public, no one would think that this sheep is mine. Subsequently, the material has a surplus production and consumption together we do not starve to death, everyone began to have their own personal items, private and individual ownership began to appear. Up to now, it seems that the history of the spiral and turn back, still from surplus materials, but began to be more diverse human needs, the long tail is growing, not only in film and television, books such information field, physical commodities as well. Supply can not meet demand, one solution is to share with everyone a piece of merchandise.

Do not worry about sharing the economic impact on the existing system, I think it will only be a supplement existing economic system, the traditional basic necessities of life will generally remain as unlikely to wear different every day, and then by many people across the clothes clean it is also less likely to approach every day with Airbnb come to room to live it. Affected is the long tail of human needs, something beyond everyday life, such as today you suddenly want to be a clay sculpture, within 10 minutes, a buy solar panels UAV carrying a full clay equipment parked in the window, facial scan pay, the next day another one of these drones take the opportunity to go through the device when connected to the back.

The point is, flow. Information and physical are in the flow.

Internet has made information flow becomes very smooth, smoothness of the ancients did not dare to think, and even people who have been unthinkable 30 years ago. As long as you want, within 15 minutes you can make almost all Internet users to know Obama is dead. But the real thing is far not reached this position, did not reach the edge.

I do not mean science fiction teleport, this need breakthroughs in theoretical physics beyond the things belonging to three steps, but the UAV + funny combination of solar cell efficiency , but it is a small step you can see across the scene . Or Further still, driverless cars + Uber also feasible mode.

"Dual" under the road to how to go solar



General trade exports dominate. In the first half, China's general trade exports 200 million solar cells, increasing 65.7 percent over the same period of solar cells for 78.6% of total exports; processing trade exports of 49.62 million, an increase of 4.2%, accounting for 19.7%.

Export-oriented foreign-invested enterprises and growing significantly. In the first half, China's foreign-invested enterprises exported 180 million solar cell, an increase of 58.9% over the same period the total exports of solar cells 73.1%; private enterprises exported 61.74 million, an increase of 28.2%; state-owned enterprises exported 5.98 million, a decrease of 23 %.

Substantially reduced exports to the EU, Japan and other emerging PV market exports doubled. First half of the export to the EU solar 62,960,000, decreased 34.5%; against Japan, Hong Kong, South Korea, Canada and India were exported 38,250,000, 26,990,000, 28,920,000, 30,120,000 and 26,410,000, respectively. surged 3.6 times, 1.5 times, 1.1 times, 1.4 times and 1.4 times; together accounted for the same period of the six by my solar for 85.5% of total exports.

2011, Chinese exports to the EU a total value of 21 billion euros (about 166.5 billion yuan) of the solar panels and associated components, exports accounted for Chinese PV 70% of total manufacturing. The European Photovoltaic dual case has thus become by far the largest EU trade frictions, the world's largest trade dispute involving [1]. 2012, by the "dual case" the impact of solar cells significantly reduced total exports, exports of $ 23.3 billion, down 35%. One year later, the impact of trade barriers not disappear, although in Japan, South Africa and other photovoltaic driven by strong demand in emerging markets, China's total exports of solar cells up, but exports to the EU are still significantly reduced solar cell of 34.5%, compared to last year fell 32.9 percent over the same period, not only that, the overall export price and export value fell significantly. Thus, China's photovoltaic products exports several pitfalls:

First, the high dependence of excess capacity, forcing companies to price competition. Overcapacity in the solar cell market, supply and demand imbalance, polysilicon prices decline, resulting in the overall industry profits. Domestic PV market has not yet launched a large scale, more than 80% of our products export-dependent solar cells [2], of which nearly 70% are exported to European markets. Overcapacity, excessive dependence on foreign trade as well as trade barriers multiple factors forcing companies to compete for market share, price competition can only maintain momentum.

Secondly, the industry urgently foreign trade development mode transformation. To the general trade export-led solar cells, general trade exports accounted for 44.3% of total exports, while only 19.7% of the export volume of processing trade exports accounted for as high as 52.4%, volume and price disparity, general trade exports price far lower than the processing trade, independent industry low position in the industrial chain, the development model urgent change. At present, China's solar cell industry has not yet established a comprehensive research and innovation system, and the lack of support of a number of high-tech manufacturing industry, so our crystalline silicon solar cell production line of high-end equipment required to import large, thin-film solar cell production equipment as well compared with foreign Large gaps, some supporting materials for solar cells have not get rid of dependence on imported products. This situation led to China's photovoltaic industry is marked "foundry workshop," the stigma, which is processing and assembling.

Apart from the EU, the U.S., India and so on my solar panels anti-dumping countervailing investigations. Back in October 2011, U.S. exports to China's solar cell anti-dumping and countervailing investigations, preliminary consolidated tax rate of 35% to 255%. September 6, 2012, in the European Union on Chinese exports of solar modules, cells and wafers anti-dumping investigation on the occasion, India has officially told me solar photovoltaic products launched anti-dumping investigations. Europe, America and India and other major exporting countries have initiated anti-dumping countervailing investigation on the cause of the entire PV industry deadly and devastating blow.

Thus, China's exports of solar cells trapped, domestic demand needs to be activated. Increase China's solar cell applications, medium and small cities and rural development on the demand for solar cells, solar cells and thus reduce dependence on foreign markets; accelerate the transformation of solar photovoltaic products, as well as trade development; develop autonomous solar products, adjusting the industrial structure; avoid international friction re-warming. Above, for the future direction of industrial development to provide some ideas.
