A Little Something on Elon Musk

06/02/2015 10:22 PM

I thought I'd share this link since there seems to be a few fellow Elon Musk fans in the house.

http://waitbutwhy.com/2015/05/elon-musk-the-worlds-raddest-man.html

Have to hit Half Price Books and order the biography tomorrow.

Enjoy!

Well, certainly not me pal.

I don't believe in self driving cars (I know they exist and have been tested).

I don't believe in electric cars as a cleaner alternative to fuels; electricity still has to be produced burning coal, so you add the loses of that conversion to the loses of a further conversion on the EV.

I don't believe in a gigantic network of charging stations available everywhere any time soon.

I just refuse to discard a humongous battery every 7 years and replace it at the cost of a brand new car (even if a could afford it).

Some dentists think that ultrasonic drills are safer, just because they can't hear them.

I suggest you do a little research.

Electricity can be produced from a wide variety of sources. Many of those sources have very small environmental footprints (solar, wind) or much smaller footprints (hydro, nuclear) or better footprints (NG) than coal. Many distribution schemes operate with excess network power, which should and is being used to charge cars, resulting in very low net energy infrastructure requirement.

Electric cars are very good storage vessels, in addition to excellent transportation. We need more, because energy is notoriously expensive to store. I just drove a Ford Focus all electric, it was fantastic.

No one is going to sit even 15 minutes to charge their car. They do it at home or work.

A 28 KWH Battery is 100% recyclable and requires zero maintainance during its life time. It is far more reliable and practical than the best IC out there.

Some people think.

Practical?? I was ok with everything you wrote up to that point. Practical is in the eyes of the driver. For many people a pure EV is extremely unpractical. As for reliable, there are not enough years with fielded systems (i.e. in the hands of the driving public) to be making that bold a statement. It is better to be reserved and pleasantly surprised later, than to be over-optimistic and disappointed down the road. I have plenty of experience with battery powered manned submersibles, and while the batteries, motor drives and motors are reliable to a point, they still have their failures. I'm driving a 2005 VW Jetta with over 170,000 miles. It's never broken down. That's a lot of miles and a lot of hours.

Elon Musk doesn't like hybrid cars for some reason. But a hybrid is the best solution because while it has an electric drive unit, it also has a fuel drive unit or a fuel based charging capability.

That being said, the judges are still out as to what combination of technology is the best for a specific user. For relatively short trips it is best to be mostly electric. But who wants to wait around for energy to be stored away. For commuting to work, I see no reason why the fuel consuming part can't be charging the electrical storage part while you work inside some building.

For longer trips, the fuel consuming section needs to be larger. It can also be used to improve performance. But to use straight fuel and no electric is very wasteful for day to day use. My vehicle idles by turning OFF at traffic lights and in traffic jams I tend to run only on stored energy. It is impossible to beat the cost of doing that.

Instead of having to accelerate from a stop to cruising speed, fix the damn traffic light controllers. Who in there right mind would have thought it was a good idea to have a Civil engineer handle automated traffic control? Better yet, build intersections so that traffic lights are not needed. Make them flow properly. Anything else is a rip off of tax dollars or rupees or dineros...

Not a fan in the vernacular sense.

I find his activities interesting.

At least he is putting up his own money first.....maybe that's the key to his success. He takes risks that he has to wear personally.

He has also had some good luck and used it well.
