The new MURS Alert offers the ability to monitor activity at remote locations – over several miles! Manufactured by Dakota Alert , the MURS Alert has many different applications; it can be used by security guards, small businesses and also by hunters monitoring game trails; any scenario that requires immediate notification when someone or something enters a monitored location. Authorized by the FCC, MURS (Multi-Use Radio Service) is a license free service that allows the user to transmit voice and data. MURS also allows a maximum of 2 watts of output power. This means greater range than other license free radio services. MURS Alert Transmitter: The MURS Alert transmitter utilizes passive infrared sensor technology that will send an alert signal to the MURS transceivers in order to notify you that someone has entered a monitored area. The transceivers can also be used for two way voice communications. The MURS Alert transmitter is capable of sending 4 different alert messages to the transceiver. The alert signals will be in spoken English and are easily selected at the transmitter so that separate zones can be monitored at the same time. MURS Receivers: The MURS base station transceiver receives alert signals from the MURS Alert transmitter and also can be used for two way voice communications between other MURS transceivers.

No one ever really thinks about it when they walk into a store and they encounter a brightly lit environment that invites shoppers to look closely at each product for endless hours but the thought that went into lighting a super store is a painstaking process and a strategic process that ensures shoppers stay in the store and don’t experience shopper’s fatigue. Any person in charge of designing a store, warehouse, office or any other environment where people will congregate should pay special attention to the lighting needs that will help to ensure the proper atmosphere for productivity, visual stimulation and regulatory needs. This can be a daunting process but there are numerous reasons why proper commercial lighting is a must. An improperly lit environment can cause health issues to workers like headaches, migraines and mental fatigue. Not only will this hinder productivity it can have a dramatic increase on absence rates and even attrition rates. When a workspace is properly lit it allows a worker to focus clearly, be more productive and even work longer periods before rest is needed. This can have a very large affect on employee morale, production output and it can help maintain long-term employment.

Chemist Daniel Nocera of MIT made news by trying to mimic photosynthesis, and improve on it. The idea seems simple: split water into hydrogen and oxygen with sunlight, and then recombine them which releases the energy in a fuel cell when the power is needed. The goal is to do both these things cheaply. Nocera has come up with a way to split water into its constituent elements that is less expensive than the technology used today. Nocera’s idea is simple: Split water into hydrogen and oxygen with sunlight. On the other side he says a “new catalyst” for fuel cells is what’s needed, but he’s hopeful that he’ll find it. He predicts success in less than a decade. Nocera’s paper, Chemistry of Personalized Solar Energy published in Inorganic Chemistry, describes the plan as a solution to the solar energy collection, storage and use using the hydrogen as the storage medium. The paper’s abstract says: Personalized energy (PE) is a transformative idea that provides a new modality for the planet’s energy future. By providing solar energy to the individual, an energy supply becomes secure and available to people of both legacy and nonlegacy worlds and minimally contributes to an increase in the anthropogenic level of carbon dioxide. Because PE will be possible only if solar energy is available 24 hours a day, 7 days a week, the key enabler for solar PE is an inexpensive storage mechanism. HY (Y = halide or OH − ) splitting is a fuel-forming reaction of sufficient energy density for large-scale solar storage, but the reaction relies on chemical transformations that are not understood at the most basic science level.
