Comment What will the Aluminum industry think? (Score 1) 236

I have owned cars made with large amounts of aluminum. Aluminum cars are very expensive to repair after accidents. I wonder how this metal will compare with Aluminum. If I could have a lightweight, inexpensive to repair car it would be great: less expensive to drive and to insure. This technology won't displace carbon fiber in Lamborghinis, but how about Aluminum in Audis, Fords and Teslas? How about Boeing and AirBus? Could this replace a lot of aluminum?

Comment Re:Bad weather.. (Score 1) 242

"Bad weather" as in rain is not a problem. The problem is snow and ice. Tesla's technology comes from Mobileye inc. Tesla's technology and Google's technology do not work in snow and ice. It will work at night and in many rainy conditions although glare can cause problems at night in the rain. The sensor's depend on seeing painted lane markers, which may be difficult when there is glare from light in the dark in the rain.

Comment Snow and ice are unsolved problems. (Score 1) 397

Dark and rain are not problems for Google cars or cars using Mobileye company technology (Tesla) The big problem is snow and ice. Humans are amazingly advanced at driving on snow covered roads. I foresee trouble in the parts of the world with snowfall if a generation of drivers emerges that is very dependent on self-driving technology. You need lessons and experience to become good at snow driving and I feel self driving cars are many years away from being safe in snow and ice.

Comment Tesla asks for huge tax on meat: (Score 1, Insightful) 291

Suppose Tesla was concerned about man made climate change. The company might want to decrease animal protein consumption because methane from farm animals is far more important than automobile emissions: If the government can force us to drive different cars, they can force us to eat different foods. Come on Tesla: lobby to force all bacon and hamburger be made with 55% tofu. See how popular you are. Disclosure: I drive a P85D and I love it. It is an amazing car and works great for my family.

I don't care about thinness. I want to use my phone hard and have it last a full day. I have an aftermarket battery in my S4 and love it. The new battery will charge quickly only with a special charger. If you connect it to a regular USB outlet you won't get very far very fast. The built in battery doesn't have to die. If it loses 30% of capacity before a typical 2 year US contract is up you will want to replace it.

A 100 year old steam car can be kept running. A 70 year old Ford can be a daily driver. What will happen to an electric Tesla when the first capacitor on the control panel CPU craps out in 10 years? Will spare motherboards be available? Will you be able to drive the car when the computer controlling the battery cooler dies? Or will it become a brick? That central panel isn't the radio, it is indispensable to the operation of the vehicle! BTW I've driven a Tesla S Supersport and it is a lot of fun to drive and a worked very well.

Comment Why do cars get all the negative press? (Score 0) 330

If governments can tell you what car to drive and how much CO2 it can emit, why not tell people what they can eat, how much animal protein, and put a methane tax on cows and pigs? All this concern over cars and driving and global warming but eating meat seems to be worse than driving a Hummer. http://www.scientificamerican....

Comment Smoking cases more than lung cancer and COPD (Score 1) 401

Everyone thinks of lung cancer and COPD/Emphysema. I work as an anesthesiologist and I can tell you one of the biggest problems smokers get is disease of the arteries. They get heart attacks because of blocked coronary arteries. They get strokes because of blocked carotid arteries. They get peripheral vascular disease (PVD) which means legs that become painful when walking due to lack of oxygenated blood. Combine smoking with diabetes and you are guaranteed to have vascular problems in life! So don't imagine coughing up blood and dying of lung cancer, don't imagine COPD and needing oxygen to slowly walk 100 feet. Think of blocked arteries to the brain and strokes, think of blocked arteries to the feet and gangrenous toes, think of blocked coronary arteries and getting your chest sawed open to bypass them. Think of blocked arteries to the penis and (Sorry I can't even bear to think of this!) Smoking is bad mm'kay

Submission + - How do I insure a consumer RAID array lasts a long time? 4

olddoc writes: I am a home user and I back up all my digital pictures, home movies and several computer install images. This requires a few terabytes.
I look for 5 year warranty HDDs but I wonder if I should use motherboard chipset RAID, Windows software RAID, a stand alone box or a major vendor's (LSI, Adaptec) add-on card? In the past I have had a disk in a motherboard RAID5 array fail and I kept the system off until I installed a replacement drive and it worked like a charm with no data lost. How would /. users set up 4-10TB of storage that they could move on to the next system down the line? Would an LSI RAID array be supported or readable 5 years from now if the card died? Software RAID seems like a good solution since if a mobo fails the array will be easy to move. I also have a 4TB drive in a bank safe deposit box and I keep buying SD cards and saving them after a year or a major vacation.
