The standard iphone os is capable of much more than it allows you to do. How do you think push email works? How do you think the phone app works?
I jailbroke my phone for the extra features, I could care less about the pirated apps. I have backgrounder installed which allows limited multitasking. I listen to public radio player(c89.5 seatle, 89.9 madison) which helps me get my groove on while I browse the web, use google reader, read email, whatever.
I also have adblock for the iphone and a small hosts file which combined with iphone's lack of flash filters out most ads.
Yes multi tasking it eats the battery faster but it is worth it. I have version 3.1.2 and used blackra1n(excellent).
Humans are not monogamous. Humans did not evolve as a monogamous species. Pairing may be beneficial to raising children, but humans have a long history of sleeping around.
In species where females usually mate with a single male during a breeding episode, penises tend to be small and uninteresting. In those where females mate with several males (whether by choice or by force), penises are typically larger, and come with fancy decorations such as grooves, nobbles, and spikes.
The nob on the human male penis was specifically designed to scoop out a rivals sperm and deposit seaman deep into the vagina at which point the penis becomes soft so as to not scoop out its own deposit.
I used to have DSL through TDS until I started having problems with nexflix buffering. The movie would play fine for 1 hour and then start to have buffering issues. I did some network speed tests using dslreports and a local speedtest server. If I was just doing normal web browsing and then did a speed test I would get a decent speed, plenty good for netflix streaming. Then I tried watching a movie, one hour into it buffering started, I shut down the movie and immediately ran a speed test and found that my bandwidth had been cut exactly in half.
I repeated this test a number of times and then switched to cable internet and told TDS to get fucked - they wanted me to switch to a more expensive plan but did not admit to throttling my connection. Now I have higher speed cable(charter) and haven't noticed any throttling or had any trouble with netflix playback(HD).
Today hackers gained access to my bank account and increased the ballance to 100 millions dollars without alerting authorities. Actually that didn't happen. My bank account is perfectly secure. There are no hackers anywhere that are smart enough to do such a thing.
Peak oil doesn't mean that we are going to run out of oil, it means that we are going to run out of cheap, high quality, easy to extract oil.
Example: Iraq just sold the rights to develop their oil reserves for $2 per barrel. These contracts will probably go down in history as the best oil extraction deals ever made because Iraqi oil fields are as sizable as those in Saudi Arabia, the oil is high quality: easy to pump easy to drill, the fields have always been underdeveloped and underutilized and all other large developed oil fields are in decline so the price is sure to spike higher even as production ramps up.
Oil shale can be a source of oil, but it is not a source of cheap oil which means that our society will need to change fundamentally as the price we pay for energy increases faster than the rate of inflation.
Using electricity from coal fired power plants to power a 90% inefficient incandescent light bulb releases more mercury and radioactive particles into the air and water than the mercury used to make a CFL and you can safely dispose of a CFL.
The cool thing about electric cars is that they are so much more efficient that you don't need batteries that are as energy dense as gasoline. The tesla roadster has a range of 240miles with a battery pack that holds 53kWh. A gallon of gas has the energy equivelent of about 35kWh. So a tesla can go 240 miles on only 1.5 gallons of gas. This is because the battery and motor are so much more efficient than an internal combustion engine which wastes most of the gasoline energy as heat.
So in order to build awesome electric cars we either need batteries that can be recharged a little more quickly or batteries that can store a energy a little more densely, but we don't need energy storage as dense as gasoline for electric cars to work well.
Wasting wind power to create hydrogen through electrolysis(only 60% efficient) and then using more energy to futher convert it into liquid fuel to burn in conventional engines(20% efficient) might make sense if we had a large excess of wind energy. The problem is that while wind energy is clean and there are many good locations to site wind farms in the US the amount of electricity produced does not come close to meeting our demands for clean electricity. Maintaining our traditional reliance on liquid fuels for transportation is the wet dream of oil industry execs but it doesn't make sense to perpetuate wasteful energy usage as energy becomes more scarce and costly.
Battery powered electric vehicles(85% efficient) are in testing right now by most major car manufacturers. They will be on dealer lots within 2 years, and while they may not be very affordable when launched their fuel efficiency and ability to use cheap/clean energy will help offset the cost. We don't need to wait 50 years to switch our transportation system, it can happen gradually over the next 10 years as the current fleet of cars are replaced with new ones.
Btw Huge wind farms in remote locations is not the only renewable energy source, residential solar power can create energy where it is needed and power the cars of the future.
Apple will never an app that would allow users to bypass the applestore.
You can however jailbeak your phone and then install apps from source repositories. I have used cydia to install a number of unapproved apps, but so far I haven't been that impressed by these "free" black market apps because most of them contain advertising. And this is likely to break every time apple releases a new version.
Not only do the useless voicemail messages make you waste your minutes, but they make leaving voicemail more time consuming and less appealing, the alternative to voicemail messages is SMS which carriers make tons of money on because texting is usually an extra charge on top of your standard service.
Electric cars of the future will not carry and do not need the energy equivalent of 10 gallons of gasoline. The tesla roadster has a range of 240 miles which is provided by a 53kwh battery pack. The car that MIT is building has a range of 200 miles so their battery pack is probably 45-48kwh. Since one gallon of gas is 35kwh and because efficient battery management systems rarely fully deplete the battery that means that an electric car with this type of range only needs the energy equivalent of 1 gallon of gas for a fast recharge. So you are off by a factor of 10 in your calculations.
The current tesla roadster can be fully charged in 3.5 hours using a 220V/70A, their next car, the model S will support 440V charging in order to significantly improve charging times - but we are sill talking hours for a full charge. Despite the long charging times this level of performance will probably be good enough for most people most of the time given the average daily commute of 20-40 miles.
You are correct that what MIT is trying to do will be a huge energy draw that cannot be supported by current residential electric services. They are connecting directly to their campus power plant which will never be possible for your average consumer.
Lightning strikes should be harnessed as energy. You would need some fancy surge protection and a way to slow the electric discharge enough to feed it into the distribution network, but I bet one evening thunderstorm could power a lot of homes.
You were very generous with 40mpg. The highest mileage a 2009 car gets on E85 is only a paltry 16 city 23 hwy, much lower than the 22 city 32 hwy on gasoline. Most new vehicles that burn E85 are trucks so the cafe average is probably closer to 13mpg, which would be worse if running on E100. http://www.fueleconomy.gov/feg/byfueltype.htm
plants are only about 6% efficient(max) at converting sunlight into sugars & cellulose. Modern solar panels are around 20% efficient(very expensive space panels are at 40%).
ethonol must be distributed by truck or rail(there is no pipeline yet). electricity transmission loss is around 3%.
How you use the energy matters also. Internal combustion engines waste most of the energy as heat(75-80%) and use only 20-25% of the energy to move the car. Electric batteries and motors are around 85% efficient.
Electricity wins. Now if we can just get some affordable batteries and solar panels...
Not to mention that the gas lawnmowers are much more polluting than the truck that hauls them.
Gallon for gallon or, given the size of lawnmower tanks, quart for quart the 2006 lawn mower engines contribute 93 times more smog-forming emissions than 2006 cars, according to the California Air Resources Board. In California, lawn mowers provided more than 2 percent of the smog-forming pollution from all engines. http://www.nytimes.com/2006/04/24/us/24lawn.html
Wireless power transmission is inherently inefficient. Electric cars with batteries are about 85% efficient. Trying to power an electric car with wireless power would only be about 40% efficient.
Electric trains with electrified rails are probably close to 90-95% efficient. So if you could put the car on a rail or have another hard/solid connection then an electrified roadway might be feasible(although costly).
Batteries(95% efficient) * Electric Motor(95% efficient) = 90% efficient ICE(20-25%) * Batteries(95% efficient) * Electric Motor(95% efficient) = 23% efficient
The tesla has a range of 220 miles on 53kwh of batteries. The amount of energy in the batteries is equivalent to about 2 gallons of gas. Electricity cost to fill the pack, about $4.
I agree that the Aptera is a more innovative design, the slippery shape is more aerodynamic and the front wheel drive train is more efficient at capturing regen brake energy more effectively. The Aptera will initially only be sold in California and I am not sure how a three wheeler would handle the snow so I probably wont be buying one soon.
But the Tesla pure electric drive train is more efficient overall and they have been building and delivering vehicles, but as you said 120k is too much for a vehicle. The model S is more tempting, but still very pricey.
Since CFLs last about 5 years the break even point is way above $3/lamp.
I switched my whole house, cost me $40, but now I save $15/month on electricity.
Electric motors do this also, so until they fix that issue, I'll hold on to my steam powered appliances even if I have to burn my house down to power them!
