Optrom, Japan, will launch the "ECOOL", a cold-cathode tube (CCFL) lighting fixture jointly developed with Taiwan's GTO, which can be installed on existing fluorescent lamps. Two custom-made CCFLs for LCD TVs are built into the polycarbonate of the same size as the 40W straight tube fluorescent lamp. An inverter is built into the back of the CCFL. The installed lamp ballast can be removed and the AC power can be directly input. The power consumption is 27W and the luminous flux is 2000lm. The overall efficiency is about 74lm/W, the direct illumination is 390lx, and the brightness can reach the level equal to or higher than the existing fluorescent lamps. The life (the brightness is reduced to 70% of the initial brightness) is equivalent to LED lighting, which is 40,000 hours.

In order to comply with the revised Energy Conservation Law, low-power and long-life products are becoming more and more popular, and it is expected to be introduced into factories and distribution centers. The competition for this product is straight tube LED lighting instead of fluorescent lamps. ECOOL is characterized by a price of only 7,500 yen, which is 1/2 to 1/3 of straight-tube LED lighting. By cutting electricity bills, initial investment can be recovered in about three years. The company said with great confidence that "companies that intend to introduce fluorescent LED lighting will import if they see the product." Although there is no disclosure of technical content, the company is applying for relevant international patents for the part and structure of the lamp under the Patent Cooperation Treaty (PCT). In addition, inverters that play an important role in low power consumption are not patented, but are black boxed. In order to make it easy to understand the internal structure after disassembly, epoxy resin is used for encapsulation.

Optrom originally planned to develop LED lighting. However, in the face of cost and heat-resistance issues, the company adopted the GTH proposal for CCFL and developed ECOOL. The product will be available in August 2009. GTT is responsible for production and Optrom is responsible for import and sales in Japan. Finantec, which is funded by Optrom, will act as an agent, and Optrom will strive to build a secondary agent to expand sales. “The initial sales will be tens of thousands/month, and I hope to sell 10 million in a few years.”

Zcoin is a digital currency that aims to create a truly anonymous method of trading.

One big obstacle to Bitcoin's emergence as an electronic currency is that all its transactions are visible on a public blockchain. As a result, Bitcoin's interchangeability has been controversial. Some people or companies (mainly exchanges) will not accept bitcoins for certain addresses. Such scrutiny runs counter to Bitcoin's core philosophy.

Zibo is the latest attempt to create a currency that can be verified without knowing the input and output of a cryptographic signature. This is called a zero-knowledge proof. DASH and Monero are two other digital currencies that are also trying to solve the same problem using different encryption methods.

The whole world is buzzing about zeros. A lot of people respect the Zibo development team. They have received investments from prominent Bitcoin venture capital firms such as Pantera, Distributed Capital, and Digital Currency Group. Bitcoin luminaries such as Roger Ver, Erik Voorhees, Barry Silbert, and Li Xiaolai have invested in Zcoin out of their own pockets. Confirmation bias is an important factor in why investors choose one project over another. If the leading players in the bitcoin industry are investing, it must be a good thing, right?

Unfortunately, Zcoin did not issue an initial currency offering (ICO) to investors. ZEC is the three-digit currency code for zerocoin. ZEC will initially be mined, just like Bitcoin. But unlike Bitcoin, which was full of unknowns when it was first launched, ZEC's founding block is a high-profile one. ZEC prices have skyrocketed because of extreme demand.
