How Modern Light Bulbs Have Evolved


You’re visiting your grandmother’s house out in the plains of Kansas. There’s a storm brewing, and the weather service has announced a Tornado Warning for the area. Walking around the house shutting all the windows, you happen to notice that the sky has blackened. Looking up, you spot something ominous approaching — a deadly tornado! You quickly file everybody out of the house and into the storm cellar that sits beside the back porch. You cram the family down the narrows stairs and shut the cellar door behind you — you’re safe. You walk down the stairs and feel around… read more

Sunny Spaces Can Give Energy Levels A Boost

Sunny Spaces Can Give Energy Levels A Boost

When the hours of daylight get shorter as weather turns colder, it can have an effect on emotions and behaviors. Allowing natural light into a room can warm up the space, and according to research it can increase a sense of happiness, too. One study looked into what effect light exposure might have on daytime functioning. Though it may not be too surprising, it was found that those who had received more daytime light experienced more liveliness. Light levels were constantly measured and activities were recorded hourly over the span of a year. Areas like activity patterns were reportedly most… read more

Teenage Girl Invents Body-Heat Flashlight


15-year old Ann Makosinski of Vancouver, British Columbia recently invented a flashlight powered by body heat as battery companies looked on with fear in their eyes. She’s one of 15 finalists for the Google Science Fair competition’s top prize. Her submission to the competition is a heavily-modified flashlight. It gets its power from the heat generated by the palms of your hands. Makosinski’s been interested in alternative energy since the sixth grade, she says, and is particularly drawn towards the creation of long-lasting power sources. And what greater source of long-lasting power lies around her than the human body? Curious,… read more

A Cheap Alternative to Light Bulbs

Cost-Effective Candles

During the morning and afternoon hours we’re blessed with sunlight to guide us through our daily activities. But our activities don’t end just because the sun sets. This is when the greatest use of light bulbs starts and we incur a good portion of our electricity costs. Compact fluorescent lights greatly lower the overall cost. Though they initially cost more, about $6 as compared to $1 for incandescent, after 17 months they end up saving $3.64 a year. They also last about 13 times longer. Candles are another great way to reduce use of light bulbs. Now used mostly for… read more

Teaching Kids About Energy

Tio Ghost Light

Energy conservation is a growing subject, and one that kids should be aware of. The younger children learn these habits, the longer they will practice them over their lifetime. We now know enough about the effects of energy consumption and over-consumption that we should be teaching today’s youngsters about the importance of saving energy. Tim Holley has designed a light switch to do just that. He calls it “Tio,” and it’s a ghost-shaped light switch that gives kids a visual reminder of how much energy they’ve used by leaving lights on. Tio starts out a green and smiling ghost. If… read more

Algae Powered Lamp

Algae powered light

In the world of cool eco-friendly inventions, 2012 and 2013 have so far been the best years for innovative designers to showcase their products. A great, independent design venture website called Designboom has told us of an ingenious attempt to reinvent the lamp by a designer by the name of Mike Thompson. Basically, Thompson has invented a lamp that runs on algae, water, and . . . well, CO2 from your breath. You store the lamp outside in the daytime, and photosynthesis will generate electricity through the algae. When you need to use the light, the electricity will be released and power… read more

Simple Things

Innovation in developing nations

Science has always helped mankind with all it can to make life simpler and healthier. Revolutions happen around the clock from fountain pens to rockets helping humans in one way or the other. Certain innovations are made accidently while some are invented to meet problems but in most of cases they don’t reach the common man quickly or are too pricey for them to afford. Simple technology and easy-to-use innovations are better in places where energy, education and materials are plentiful.  In developing countries where resources are scarce  it could even be as simple as developing a water bottle but it makes a… read more
