Open Technology Development Sponsors Phoenix Cal Ripken Dynamite Youth Baseball

We are happy to take part in the opportunity in helping promote local Phoenix, AZ athletics. Open Technology Development, LLC is proud to announce that we are one of a few sponsors of our local Cal Ripken Dynamite Youth Baseball athletics organization. We are proud to participate in local athletic programs in our community as they are necessary to bring people together and teach our youth about fitness and good sportsmanship. Doing this as a hobby can be pretty tiring and it comes with a lot of legwork, but it is very fulfilling. It doesn’t affect me as much as it used to, mainly because I found an excellent health supplement that has been working great for me. It is natural, and very effective. I highly recommend it. If you would like to check it out, check out their website here:

We hope this is the first in many programs that we will participate in for the Phoenix valley.

Battery Technology Developments: Week of March 9, 2009

The last few days the technology news has been inundated with developments of two new energy storage technologies.

0-100% in 10 seconds!
The first is a report from MIT.  The researchers have discovered a way of improving lithium based chemical battery systems.  Their findings show a more efficient way of increasing the available locations for lithium to be transported by increasing the mobility aids in increasing the ability to charge rapidly and increasing overall battery performance.  A capacity of 166mAh/g can be attained when configured for lower currents and a capacity of 110mAh/g was achieved when configured for high currents.  This all allows for high charge, recharge and discharge currents, thus creating a battery that can be charged in a relatively short time, say 10 seconds.  This could lead to many advances in portable electronics, electric and hybrid vehicles and renewable energy storage systems.

At Open Technology Development we look forward to seeing if this discovery will be further investigated and attempted to be scaled for manufactured applications in the next 5-10 years.

Spun up!
The second interesting technology comes from researches at the University of Miami, University of Tokyo and University of Tohoku. Their discovery takes a unique approach other than conventional batteries that use chemical storage, i.e. Lead-acid, NiCad, NiMH, Li-ion, etc. their new battery concept uses magnetic energy storage. The new ‘Spin Battery’ uses a large magnetic field to be charged thus creating an electromotive force potential within the new Spin Battery material, nano-magnets. Current is produced by a process called a spin polarized current. This is another possible application from the fields of nanotechnology and it’s subcategory of spintronics. Although promising the output of these new Spin Batteries are small due to the small amount (diameter of a human hair) used in the experiment.

At Open Technology Development we look forward to seeing if this discovery will be further investigated and attempted to be scaled for larger applications in the next 10-15 years.
