Artificial Leaf

Monday, March 28th, 2011

The artificial leaf could be one of the most important inventions of this decade.  No, this wasn’t the first time someone has invented such a thing, but it was the first time someone perfected the technology and is on the cusp of making it widely available.  Meet Daniel Nocera, Ph.D. read more »

Silicon-based LED Bulbs

Thursday, March 17th, 2011

If you are concerned with light efficiency at all, you know that LED bulbs are the future of lighting.  They are more efficient than both incandescents and CFL’s.  ESL bulbs are currently giving them a run for their money due to the high initial cost of LED’s, but Bridgelux thinks the new silicon- based LED bulbs they are working on will change that. read more »

Recharge Alkaline Batteries

Thursday, March 17th, 2011

You heard that right.  Alkaline batteries can be recharged.  A battery is nothing more than 2 or more electrically active metals with an electrolyte in between them.  The electrolyte both separates the metals and allows electrons to go between the metals.  When a battery discharges, a chemical reaction takes place within that little AA battery to produce the current.   read more »

Hydrogen From Urine

Tuesday, March 15th, 2011

A hydrogen economy would be great.  We could potentially have a limitless supply of energy because it is one of the most abundant elements on the planet while the only by product of its combustion would be water.

Currently a huge detractor is that hydrogen is expensive to produce.  Water is very stable, and it takes a lot of energy to break apart water molecules into hydrogen and oxygen.  Gerardine Botte of Ohio University has created a new catalyst that can extract the hydrogen from urine. read more »

Making Electronics More Efficient

Wednesday, March 2nd, 2011

Have you ever wondered why laptops need the “charging brick”?  Laptops have had these for as long as I can remember.  In laptops, high-voltage AC power is converted to low-voltage DC power.  Apple helped to make them a little less unsightly by making them a bit smaller.  However they are still cumbersome at best.  Fret no more.  A Google Ventures backed company called Transphorm has created a technology that will eliminate the charging brick. read more »

Solar Energy Telescope

Wednesday, March 2nd, 2011

There has been a lot of research into making solar panels more efficient collecting the sun’s energy.  However, Roger Angel and researchers at the University of Arizona are tackling the problem of solar energy collection from a different angle.  The goal is to make solar energy as affordable as energy from fossil fuels at a $1/watt installed. read more »

Solar Hot Water Heating Not Just For Roofs

Tuesday, August 24th, 2010

Eliosolar has taken the idea of a solar hot water heater to the next level.  Traditionally when people think of solar hot water heaters, they are thought to solely exist on roofs, but Eliosolar has designed them so they look like awnings, fences, guardrails, canopies, and a myriad of other accents on a house.  They combined the idea of shading the house from the sun and collecting the sun’s heat to make hot water. read more »

Recycle Tires And Make Sinks

Tuesday, August 24th, 2010

The Santa Monica, California-based design firm Minarc has come up with an ingenious way to reuse old tires and make them into bathroom sinks.  The rubber on tires are one of the most wasted materials on earth. In the United States, about 300 million tires are discarded every year. read more »

Solar Powered Toothbrush…No Toothpaste Needed

Thursday, August 19th, 2010

Now that we don’t need soap for our dishes and we also don’t need to replace our razors nearly as often, a similar technology has come to toothbrushes.  Actually, the technology has been around for about 15 years.

Dr. Kunio Komiyama and his colleague Dr. Gerry Uswak are testing 120 Canadian teenagers willing to brush with the solar powered toothbrush and go to the dentist more frequently to document the effectiveness of the toothbrush.

Fifteen years ago, the first model introduced a titanium dioxide rod embedded in the neck of the brush just below the nylon bristles.  Light activates a wet rod thereby releasing electrons which react with acid in your mouth.  This helps to break down plaque without the use of toothpaste. read more »

Diamond Tipped Razor Blade Lasts Years

Wednesday, August 18th, 2010

One of the things that I most hate to buy at the store is replacement blades for my razor.  They are entirely too expensive and are getting more and more ridiculous as more and more blades are added to a single razor head. read more »
