Saffron’s Drift Light is here to help. The Drift Light is like a normalAmanda Kooser reviewed the Drift Light earlier in the month. Kooser reports that during the first night, she was highly aware of the way the light was dimming, but during the next few nights, she never caught the light turning off because she was already asleep. As somone who claims to have “notorious” sleeping troubles, this would imply that the Drift Light works pretty well.

Kooser says that since you know the LED light bulb will dim over the course of 37 minutes, it’s easy to plan for the light to turn off around the time you want to fall asleep. The most compelling statement Kooser makes about the Drift Light: “There is something soothing about the world dimming around you. It’s like being a kid with an early bedtime, sensing the sun set outside your window.”

I’m interested to see if this product will become popular. Have you ever tried anything like this to improve your sleeping habits? Leave a comment, and let us know!

The concept of fuel cells as an energy source is credited to a chemist, William Grove. He demonstrated in 1839 that electric current could be produced by an electrochemical reaction between hydrogen and oxygen over a platinum catalyst. Thereafter, many alternate forms of the technology emerged for producing electricity from various materials and catalysts.

The main reason why fuel cell companies have not been profitable is due to startup and operational costs. Although fuel cells provide clean, inexpensive energy, it is much simpler to use coal or natural gas. These industries have been around for a long time, so their processes are now streamlined.  Unless legislative action requires the use of clean energy, the adoption of fuel cells will remain slow.

Fuel cells are attractive for energy production because they provide clean energy, with no harmful byproducts. Although commercial adoption of fuel cells remains slow, it is possible that the technology could become disruptive and make a significant impact on the energy industry. That could happen if environmental pollution due to the burning of fossil fuels becomes a global concern. So far, large countries that account for a great deal of pollution, such and China, have been indifferent about the pollution they cause.

There’s a lot more to the cost of a light bulb than the price tag sticker. There’s the impact on your electrical bill, the tally of replacement bulbs you’ll need to buy, and the time you have to factor in for maintenance. Sure, the light bulb in your table lamp may take just a few minutes to replace, but what about your recessed cans that are two stories away from easy access?

We published an infographic on Lighting Facts, a program of the U.S. Department of Energy, created the one below, showing the five-year-cost of 100 watt equivalent light bulbs. As you can see, the low purchase cost of an incandescent light bulb doesn’t necessarily pay off in the end:
