This is true. Granted the markets do forward price things, but do you really expect Apple to grow to the size (revenue or profit) or Exxon-Mobil? If not then they probably are overvalued.
Market cap is a completely nonsensical way of saying "what's the largest company". Market cap is simply whatever irrational price the market has placed upon a company, and has zilch to do with its actual value as a cash generating engine.
And to support your point I offer up PetroChina as an example.
Well there was a story a while back about Apple possibly becoming the first trillion dollar company by market cap which would provide some bragging for the Apple fans, but it wouldn't be true as there already was a company that reached the 1+ trillion dollar market cap. The company was PetroChina and did it on November 5, 2007
Well if he were the CEO of an oil company oil would be the new hot fad product that all the young hip urbanites insist they need to have to stand out from the crowd. Now granted there are people who insist that oil is the magic cure all product (Drill Baby Drill) but most people realize that it is just a limited resource that is a necessity of our modern world.
Now a small engine and transmission like the one from my MG Midge weigh probably 250 to 300 pounds (110 to 125 kilos or so) together and that only put out 65hp (49 or so KW). Now granted this was a 1275cc engine from 1968 and a modern engine of similar size would probably put out closer to 120 hp (assuming no turbo or supercharger) so it would seem that the weight issue really isn't one since the numbers seem reasonable. I would also assume that it would scale quite well up to something like tractor trailer since they have around a 500hp engine with lots of low end torque. Turbines can be made quite small and light since if your vehicle has a turbo there are 2 turbines on the same shaft, one connected to the exhaust on that spins the other one connected to the intake to force more air into the engine.
As a side note turbos aren't really more efficient than a supercharger since a turbo restricts the exhaust flow you need to force the exhaust past it so instead of being coupled to the engine by a belt they are coupled by gas pressure.
Also you would have your heavy and light fuel oils, lubricants, plastics, petrochemicals, fertilizers, or what ever else we use oil to make. There are a lot of uses for oil that don't involve setting it on fire.
And cars produce a lot of power. The engine in my engine is rated at 342 hp or about 256 KW. Now about 2x that amount of energy is lost as waste heat (I have used the car to warm the garage up in the winter to change oil) so the total energy output of the engine is probably closer to 1000hp but only 342hp makes it to the rear wheels.
In his mind it is probably more like a 1972 Cadillac Fleetwood with the 500 ci engine that gets 500 mpg. Since that is usually some type of similar land yacht in these stories. These cars also drive either halfway or the whole way across the country on a single tank half tank or gallon of gas in the story as well.
It might bring it closer to its critical mass and thus speed up the decay, but then my understanding of physics is limited mostly to 1st year calc based college physics with a bit of simulation of physics problems thrown in so I could be completely off on this.
You would probably want one that puts out more that 10-50 KW for powering a car or truck. I believe that 1hp is about equal to.75KW so you would probably want one in the 200 KW to 300 KW range since that would put you between in the 275 to 400hp range. Cars produce a phenomenal amount of power and about 2x as much as waste heat.
With that kind of power I will just feed it back to the grid when my car is parked at home. I suspect they got units confused as 250KW would be a good power rating for a car.
So is the power plant by my house. They have a huge pile of magic magic rocks piled out side and more arrive by train or barge (not sure which since I never see it happen).
I wouldn't worry about this as it seems making a thick walled canister (1 inch wall thickness should be more than enough) would be the natural solution so unless you are shooting it with an armor piercing depleted uranium tank shell I wouldn't be concerned. Now if you happen to be being shot at by an armor piercing depleted uranium tank shell you have bigger problems.
Well if they are 2x as efficient (which doesn't seem out of the possibility for fuel cells) as an internal combustion engine is then there is still a benefit.
Gasoline is very caustic as well, makes a good solvent, causes cancer and so on. I think if more people were aware just how bad it is they might be in an uproar about it. But alas they use it every day and think it is perfectly safe.
As far as weight of engine and transmission it can vary greatly, small ones like a BMC A-Series engine weights probably 200 - 250 lbs while one of the giant American V8s probably weighs closer to 800 lbs. Transmissions vary as well, the 4 speed manual from my MG Midget probably weight 40-50 lbs but something like a Turbo 350 may weight closer to 200 lbs. So on the low end you would get a total engine+transmission weight of 250 lbs. up to probably near 1,000 lbs. on the high end for passenger vehicles. From what I remember gasoline weight about 6 lbs per gallon so 12 gallons (probably a good average) would weigh in at about 72 pounds. Personally I think having a direct drive steam turbine system would be better than an electric drive system (why convert mechanical energy to electricity and then back as that only adds weight) and then for the electronics just run something similar to an alternator off the turbine shaft like we currently do in cars.
Now that would be an impressive trick. I would also include the hypochondriac like people who think they can tell when a EM source is on because it causes them headaches. So you know those people will make all sorts of claims even if exactly 0% of the radiation escapes the container.
surely they can put 1g of thorium in a container that won't disperse the material in an aerosol form on impact.

It is great and all that they found this to be a viable material for creating skin grafts, but it seems to suffer from the same problems as every other spider silk application or for that mater every novel new material. Basically we can't produce it in useable commercial quantities.

Apparently the ISP that supplies /. is one of the slow ones.

Sadly this is probably true. I wonder if one can get some sort of CDS or other insurance like financial investment based on Jobs dying?

Just remember the stock market prices things correctly only 2 times in an economic cycle. Once on the way up and once on the way down.

It is just so they can sell you the cooling update software patch.

I see you believe in the junk like the fish carburetor, catalytic carburetor, and the vapor carburetor then. Now normally I wouldn't pimp my own page like this but I get sick of hearing this kind of stuff. Oil companies don't care what your energy source is so long as they are the ones providing it.

That sounds like a problem that will solve itself.
