Liter of Light Turns Plastic Bottles into Solar Light

July 30, 2012

What is one of the most ingenious, low-tech inventions you never heard of but which has the potential to brighten the lives of not only people in the third-world but the west as well? Liter of Light of course - the organization founded by 10 Swiss grad students from University of St.Gallen in Fall 2011. Now at 20 people and counting the organization takes a simple 1.5 liter plastic bottle, fills it with water and bleach to keep algae from growing and uses a special adhesive to bond it in a hole of the ceiling  of a third-world shack for lack of a better term.

The result is the equivalent of a 55 watt light bulb with no electricity, wiring and of course the obvious downside - no light switch.

My sources tell me the company will bring this to the UN General Assembly on August 3rd. It just goes to show you that sometimes the most compelling new technologies are the simplest.

What may be even more impressive is how the organization makes buildings out of plastic bottles.

Are Switch Lighting's LED Bulbs the Future of Lighting?

March 8, 2012

With a heat dissipating aluminum heat sink as well as a proprietary liquid which not only cools the bulb but throws light in a very natural manner, it could be that Switch Lighting will be the GE of LED lighting. My editorial team and I were very impressed with what the company showed us at this past CES. One point worth making is these LED lights can work fine when hanging upside down making them useful for corporate/industrial applications. Other LED solutions have had overheating problems when they hang upside down and as a result the bulbs burn out quickly.

Sun-Believable: a Solar Paint Advancement

December 27, 2011

A team of researchers at the University of Notre Dame has made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy. The advance was made with nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste.

Perhaps the biggest challenge for researchers is to get the efficiency levels to be as great if not greater than typical solar cells which means around 10-15%.

American Superconductor and the Case of Chinese Industrial Espionage

December 15, 2011


Last year I had a chance to sit down with Jason Fredette of American Superconductor about their state of the art technology which allows wind turbines to be more efficient. Moreover the company talked about its strong focus on superconductor wire which is a small fraction of the size of traditional copper wire. I was intrigued – I figured this is the sort of company that becomes the next major tech innovator… One that will do very well for investors.

Home Automation Could Be Next Tech Bright Spot

June 22, 2011

The future looks bring for home automation and energy management vendors

Hold onto your hat tech investors – we already have some hot sectors like consumer electronics, wireless, the cloud, VoIP, collaboration, healthcare automation and security to name a few. Now, home automation is looking like it could be the next big thing as evidenced by this great article by TMCnet’s Peter Bernstein who goes through seven reasons why we are at a home automation/energy management tipping point.

Facebook Disrupts Data Center Market

And just like that, the vanity server gets decapitated

Google continues to suck the life out of profits in industry after industry for the benefit of consumers. For example, sure Garmin is worth $7B but it was once worth $25B! Why? In-part because you can now get free turn-by-turn GPS of excellent quality with your Android phone.

Meetings, Earnings Calls and E-Mail

February 23, 2011

Its been perhaps one of my most productive days - I eliminated 1,500 emails - about 800 of which were in the "important - save for later" bucket meaning they either got zapped or required some action. Generally the latter. I also had a chance to have a zillion meetings and listen to part of a media company conference call - I won't say which one but to me the amount of information a public company shares has always been fascinating from a competitive intelligence perspective.

One thing I found interesting on one of the recent calls I've sat on is how a media company touts an increase in social media sharing as if it is unique to them and isn't taking place across the web.

For the latest news check out the video below from Tammy Wolf in the TMC Newsroom which discusses the new BMW i series of products and Chinese social media company IPO

Rich wearing the TMC hat
(No, I couldn't find any St. Bernard pics)
Apologies for not blogging in some time - I've been wearing my running TMC hat as CEO which means meetings, strategy sessions, mission statement updates, etc. TMC is growing rapidly and it is an exciting time to be in media and TMC is fortunate to have some really great customers partnered in our success and loyal readers like you. I am always amazed - when you become a blogger you have so many ideas, you can't get them all out regardless of how much time you have. I want to spend the rest of the night writing but alas, I cannot.

Electronic Warfare is the Future. Are You Ready?

Stuxnet is Victory at Entebbe 2.0

The Stuxnet worm alleged to be the work of Israel and the US was designed to target and disable Iranian centrifuges by increasing their speeds to dangerous levels while reporting to operators that all was well. The latest report from the New York Times shows this worm has also hit five industrial sites in the land of Ahmadinejad.

It’s no secret most of the world does not want Iran to get nuclear weapons and the best weapon being used to deter the country’s nuclear program was sanctions and if they are working it would be tough to know it as the country are prospering greatly as the price of oil is much higher than what Iran has budgeted.
