Energy Saving Nano-Carbon Light Bulbs Could Outshine CFLs and LEDs

A Taiwan university research team has been awarded a patent on energy efficient nano-carbon light bulbs. Unlike popular CFL bulbs and LED lights, the new nano-carbon light bulbs and tubes use a mercury-free manufacturing process and can be easily integrated into existing light bulb production facilities.

The advantages in environmental friendliness and economic practicality are significant: the CFL bulb was invented in 1976 in response to the 1973 Oil Crisis but General Electric decided against mass-producing the bulbs as it would cost $25 million to set up a production line.

Nowadays incandescent bulbs are on their last legs but so are the paid-off factories that produce them.

The new nano-carbon light bulbs invented by the Taiwanese research team can be manufactured at existing light bulb factories – switchover costs would be much less than those required to build and equip a whole new facility. Economics are one thing, human health and the environment are another.

Though CFL (compact fluorescent) light bulbs are more energy-efficient than incandescent bulbs, one of their main components is mercury: highly-toxic if it escapes into the environment by way of broken and/or improperly disposed-of bulbs. 

Not so with nano-carbon light bulbs. Ger Ming-Der (???), a professor in the Department of Chemical and Material Engineering at the Chung Cheng Institute of Technology, states that “nano-carbon materials can be used to produce a light source in a mercury-free manufacturing process.”

Although the research team has completed a prototype of the energy saving nano-carbon bulb, some minor technical issues still need to be addressed and solved before mass production can begin. Current estimates put the target as early as the second half of 2013. According to Ger Ming-Der, “We're seeking more cooperative opportunities with private businesses to improve our invention so that it can be mass produced.” In other words, show us the money and we'll turn on the lights!

GE decides to forgo CF production

Your statement: General Electric decided against mass-producing the bulbs as it would cost $25 million to set up a production line. is very false.
25 mil. is pocket change to GE. A huge loss of revenue do to a bulb that would last many times over is the main reason.

From the source's mouth...

The "$25 million" cost was in 1976 dollars, not 2012 dollars. According to ex-GE-employee and inventor of the CFL, Ed Hammer, "Although executives at GE liked the idea, they decided not to market it at the time. CFLs would require entirely new manufacturing facilities, which would cost $25 million. So they decided to shelve it."

While compact fluorescent

While compact fluorescent light bulbs are more efficient than incandescents, it’s important to remember that they also contain mercury. Mercury vapor can be detrimental to consumers’ and handlers’ health—from those involved with handling new fluorescent bulbs to people involved with storing, packaging and shipping used and broken lamps. Vapor released from shattered lamps can be contained in specifically designed mercury storage packages, but concentrations inside this packaging can remain dangerously high, creating a risk if the package is opened or perforated. The vapors can be captured within mercury-safe packages with the inclusion of a new, patent-pending adsorbent technology that effectively reduces vapor levels over periods of time. A Study by Nucon International, Inc., a world-wide leader in providing gas, vapor and liquid phase adsorption solutions, found the adsorbent showed an immediate reduction of mercury vapors by nearly 60 percent after 15 minutes. After 12 hours, the reduction can reach more than 95 percent. This technology, recently announced at the Air & Waste Management Association’s Conference & Exhibition, provides consumers and transporters who come into contact with used CFLs a safe way to handle them. With the vapor from broken CFLs and lamps contained and captured in safe packaging, consumers’ and handlers’ risks of vapor leaks or seepage are greatly reduced. Also, a small consumer-size recycling bag, now available, features this technology and allows people to safely store three to four used lamps at home before taking them to a retailer or municipality that accepts CFLs for recycling.

Energy Saving Lightbulbs

I always check out this website before buying any products in energy saving - My personal favourite is the Energy Smart CFL lightbulb because they're as bright, if not brighter, than a standard bulb and they're low on power usage.
