Re: Fixing Americas car industry

Here is some more of what makes todays car the way that they are.

Where the Energy Goes: Gasoline Vehicles

A car using gasoline will create from 1 gallon or 6.3 lbs of fuel, 20 lbs of co2 from an approximate 14.7 ration to 1 of which if we had to carry the mass of atmosphere to burn the fuel makes for 23.22 lbs of oxygen is required. To which the total 100 lbs of air is just for that 1 gallon. Now fill the tank up for range and you now have something that will be why conversion to other source of energy is a challenge.

For Mars_B4_Moon re #329

Thanks for providing the link about the need for driverless cars to interface with emergency services.

Your summary ahead of the link is what I am working from in this post.

Based upon the summary provided by Mars_B4_Moon, and without having read details from the link itself, I conclude that since emergency services are part of the environment in which driverless cars must operate, manufacturers are going to need to develop such an interface.  Of equal importance is the need for the government agency in the jurisdiction of which a driverless car must operate to invest in the corresponding interface technology.

This is a challenge government agencies have attempted to meet in the past, when the customers were humans.  Government agencies have implemented radio broadcast services which interrupt commercial broadcasts on AM, FM, TV and lately cable TV.   A possible solution is for government agencies and driverless automobile manufacturers to use any or all of the existing channels, and adapt the messages for the AI system in the vehicle.

This is going to be a non-trivial problem, so I expect it will require congressional oversight and financial support.

Thanks again to Mars_B4_Moon for bringing the problem to our attention.

Update: A driverless vehicle (such as a truck) that needs to cross multiple jurisdictions must be able to interface with the traffic control systems of all the jurisdictions.  The air traffic control system in place in the United States (and most countries) is a model for what is needed.

Re: Fixing Americas car industry

SpaceNut,

That thing has no suspension, what looks to be one of those plastic seats we sat on in grammar school, and the battery is held in with zip ties, but it still cost this Peter Holderith fellow who built it, $800?

Docyke Electric Go Kart Kit Constructibles Over 15 Electric Vehicles Battery Powered for Boys and Girls Kids Electric Ride on Cars Best Gifts for 5 to 18 Year Old Kids

Exactly $800, but it looks like a properly engineered electric go-kart with real suspension, brakes, etc, except that it uses 2 to 4 of Dad's electric drill batteries to power it.  Call me crazy, but if I spend $800 on an electric go-kart, I won't be doing what Mr. Holderith did.
