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 »

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 »

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 »

Solar Window Produces Electricity and Sticks Tongue Out at HOA’s

Wednesday, June 9th, 2010

It is almost universally agreed that renewable energy is the future whether it is solar, wind, wave, or bio energy.  However it seems that many home owner associations are opposed to solar panels on roofs and/or wind turbines in back yards.  There are some innovative thinkers out there that have a solution.  At Taipei’s International Optoelectronics Week, the Chin Hua solar window was making electricity from what seemed to be a regular window albeit a slightly foggy window. read more »

Smart Windows Save Energy

Wednesday, June 9th, 2010

A number of years ago, I installed a solar film that would reflect sunlight, and keep the interior of the house cool.  It worked great and the house stayed much cooler during the summer, but when the winter came around it continued to reflect the sunlight that could have been used to heat the house.  Even though I lived in Texas (where it is only cold about 2-3 months out of the year), it would still help to keep the house warmer in the winter. read more »

Shower Heats Water Without Electricity

Friday, May 21st, 2010

One of the biggest consumers of electricity in a household is the hot water heater.  Old units can continuously heat water in a tank for use.  More efficient ways to heat water would be a tank-less solution that produces on demand hot water.  Even more efficient is the solar hot water heater.  The latter combined with insulated piping provides an efficient way to get hot water.  However, what if water could be heated without water heaters or solar power.  What if water could be made hot, on demand simply by turning the water on?

The Piezo Shower does exactly that.  It captures the kinetic energy of the water running through the lattice of piping to create hot water.  The idea is similar to clothing that creates energy to charge small electronic devices.  As the water runs through the pipes, the water moves piezo electric fibers that create electricity by movement and read more »

E.Coli Cleans Nuclear Waste

Tuesday, September 22nd, 2009

EcoliEveryone knows that E.Coli makes people sick to their stomach.  Well, it turns out that it gives nuclear waste a big stomach ache as well.  It turns out that researchers at the University of Birmingham found that E.Coli break down phytic acid and release phosphate molecules which then bind to uranium.   read more »
