Timothy is correct-- you are the one whose math is off. An elephant has a gestation of 22 months, so after a year, an elephant cow is still pregnant; after another 12 months, she will have had a single calf that is 2 months old. I cannot see how you could think he made any mistakes.
I find ANYONE shooting elephants a vert troubling thing, unless they are sick, in pain, and are being euthanzed. Several years ago I was in Flint Michigan when a carnival/circus was there... the circus has a trained elephant. Overnight, some coward shot the elephant... it was laying on its side next to its tent. If I had known who the vermin was that shot that poor creature, I'm not sure if I could have kept myself from killing him. Someone like that is surely a threat to everyone he is around-- it's my guess he has committed many other crimes before and since... rape, murder, mayhem. A worthless individual.
Everything about EVs will continue to mature, including AC motors for EV use will make them more efficient, increasing range per charge and decreasing power requirements. Google "V2G"... it stands for "Vehicle to Grid"... it is a system that power companies are beginning to implement to make EVs part of the solution, not just part of the problem. The grid and the EVs plugged into it will be "intelligent"... If the grid senses it is beginning to become overloaded, it puts out a "request" to EVs to give back some of their charge to prevent blackouts. Vehicle owners that provide such power will be paid for that energy at an attractive rate, allowing the load on the grid to be less erratic. Homeowners, public charging stations, retail businesses, and apartment buildings will be installing their own battery storage systems, which will help to decentralize our grid and make it more robust against terrorists and any other anomalies that might otherwise give us the kinds of problems inherent with very centralized grids.
The power grids of the future will be as different from the grid of the recent past as today's cars differ from the best cars of the 1970's-- they will be cybernetic.
Check out Altair Nanotech of Reno, Nevada, re: their NanoSafe battery, which is far more rugged than any batteries today-- they survive undercharging, overcharging, rapid discharge, rapid charging, and will last for decades without maintenance. The Navy has been using them to replace one of two large generators on their submarines to make them stealthier and reduce their operating expenses; what they save on energy in less than two years will pay back the investment. The Army will be using such batteries to avoid the hazardous transport of tanker trucks through hostile territory, operating quiet, stealthy vehicles that can be charged from local solar power panels; they will also power radios in soldier's backpacks. Also take a look at Clipper Creek, Coloumb Technologies and others ramping up to provide thousands of charging stations nationwide. They are doing it intelligently, so grids will not be crashing.
This battery tech, if it pans out, should be the the most profound change to our society since the PC-- electric vehicles (EVs)-- mass-produced and affordable ones, that is-- that today can only manage a couple of hundred miles at best will be capable of driving thousands of miles per charge. But as a practical matter, we will opt instead for cars with a range of, say, 300 miles, but with much smaller, lighter batteries. They will only require motors a third as big... the suspension systems will be lighter and nimbler... they'll be more powerful, quicker, less expensive and better in every respect than the internal combustion engine (ICE) cars that we have toay and which I hate. I look forward to quieter freeways, less smog, cheaper transportation costs, and the other benefits such cars will bring. The one problem will be that since EVs will be so much cheaper, and cheaper to operate, our freeways will eventually become more congested unless we develop new tech that allows greater density but still allows reasonable speeds.
The major difference between bonds and bond traders is that the bonds will eventually mature.
