Fuel Cell vs. Lithium Ion
I wonder if Hydrogen Fuel Cells will be able to make a comeback. Fuel cells are attractive because, it allows a user to refuel in three to five minute and drive a long way. However, converting water into Hydrogen and Hydrogen plus Oxygen into electricity seems inefficient. Lithium Ion on the other hand is a tested technology and with the Gigafactory as well as the rest of the supply chain fortifying, the technology seems to be in the lead by a large margin.

The Security Implications of Connected Cars
Connected cars will be a huge boon for economies Worldwide. This is certainly encouraging, I am curious though, what safeguards are manufacturers putting in place to harden security ?

Now is the time to seriously address this issue and place a strong safeguards in place.

Re: Fuel Cell vs. Lithium Ion
@Brian.Dean   I am not familiar with Hydrogen Fuel Cells, but isn't Hydrogen highly combustable ?  I like the advantages of use you mention, but if Hydrogen is highly unstable - it could be another reason for lack of adoption.

In addition to the tried and true test of costs.

Re: Fuel Cell vs. Lithium Ion
Brian, the aerodynamics in the Mercedes F 015 is also because the car is powered by hydrogen fuel cells. You wonder if they will make a come back. I would say that since the technology in the Mercedes is the best of the best there is problably a reason. :) /Susan

Re: Fuel Cell vs. Lithium Ion
The nice thing about generating hydrogen from water via electrolysis is that is it essentially a simple process. Water plus electricity yields O2 and H2 – very amenable to solar energy. The problem is that H2 is so very unstable. I believe there is work being done to make a stable form of hydrogen available for fuel cells, but the process is complex and involves cutting edge nanotechnology.

Lithium ion batteries are a troubled technology to say the least. The newest and most promising improvements also involve nanotechnology, and the manufacturing processes are entirely different than what Mr. Musk is using in his Gigafactory, so he may just have a billion-dollar white elephant on his hands.

The one thing for certain is that if we move away from gas powered cars, a titanic change in energy infrastructure will be required, which is unlikely any time soon due to lack of interest due to collapsing energy prices.

Re: Fuel Cell vs. Lithium Ion
Brian, NASA also uses hydrogen fuel cells to power the shuttles' electrical systems. One benefit of this is that the crew can drink the clean byproduct> clean water. /Susan

Re: The Security Implications of Connected Cars
Technorati,

in the case of connected and autonomous cars the security comes in the networks and solutions that make the connectivity possible.

What car manufactures have to watch is the security protection against cyber-attacks and intrusions, which cause malfunctions, or threten the physical integraty of the driver or pedestrians. 

Software and connectivity for connected and autonomus vehicles will become more critical. Safety and security telematics will play an important role, thus, they need to be enhanced since the start. Security vendors are taking care of this. 

Would you buy a totally autonomous car which has option of manual mode as well. or you would be happy with a car with some connectivity? :)

Re: The Security Implications of Connected Cars
@Technocrati: What's the security issue surrounding connected cars? From what I understand, the level of security required would probably be the same that you need on your phone. What could be other threats?

Where does this leave motorsports?
It seems quite likely that within a few years, autonomous AI cars will be able to drive harder, faster and for longer than human drivers. While great for consumers and commuters, where does that leave motorsports?

A few years of drivers vs AI could be fun, but when the latter can easily outpace the former, where does that leave us? Do we say goodbyte to human driven cars forever, or will this just open up a new sport with less risk to enjoy?

@Tzubair, the FBI might fight with your car company to get access to your car's CPU lol
