That would be true if we were talking about series hybrids.
But every hybrid you can buy these days is either parallel (most) or series/parallel (toyotas). These engines are not exclusively operating in the sweet spot. Most of the benefits you get from hybridization these days come from regen braking and being able to use a smaller engine (the electric can help out during hard accels, so you don't have to size the engine to be able to handle the max output you desire, it only has to handle the max steady state output).
Also you forgot to mention that diesels have a higher temperature combustion chamber. That gets you a lot more juice from basic thermodynamics...
I don't like swapping my propane tank because I have a fairly new one. I really don't think I'd like to swap my nice new $5000 battery pack for whatever the last guy left at the station.
Keep two packs...
One nice one, that you don't want to swap out, and get a used one, as cheap as you can. Put the cheap on in when you are going to go on a long trip that would require swapping..
If the cost of private transportation continues to rise...
I could very easily see all routine transport done without private vehicles, and people renting cars, or using a car share, when they need to take the odd trip somewhere to which public transit is infeasible. That is how a lot of NYC people operate...
Of course the rich would likely keep private vehicles...
I set my parents house up with secured wifi 3 years ago... Last year my parents got a new laptop, and went about using wifi. 6 months pass. They get a new printer... I tell them that they can print from their laptop, over the network, and try to talk my dad through setting it up... After much confusion, I realize they are not on the wifi network that I set up for them, but one of their neigbhors...
My parents are smart, they just didn't grow up using computers, and don't think about the kind of things that most slashdot users think about... typical boomers... I bet 12% (or more) of laptop users steal wifi, without even knowing it...
Like MojoStan says, a lot of people have a hard time with morning exercise. If you can get away from your desk for an hour midday, I think that is the ideal time for it... There is always daylight, not so much traffic, and it gives you a nice break in the day...
Start out by walking if you are more than 100 lbs overweight, 30 minutes at a time... When you can do that without getting really sore, walk for 2 minutes, and then jog for 1, 10 times... then, when that gets doable, go to equal time jogging and walking... just keep decreasing the amount of time walking... It is the easiest way to start a jogging program. In the beginning you should not jog on consecutive days either every other day at most until your weight is coming down. And even when you are doing great, take at least one day a week off of jogging. Don't think about being a runner until you are OK with jogging regularly.
Also, and this is very important, go to a running store, not a sporting goods store, or a shoe store, a _running_store_, and get fitted for a pair of shoes. A good store will either put you on a treadmill, or have you walk barefoot with someone watching so they can analyze your gait, and determine what type of shoe you need. For a lot of big people this is the difference between injury and a new healthy hobby...
Here's some unconventional wisdom for you, in order to get fat, it takes insulin to move the glucose from your blood to inside the adipose tissues, if you are doing weight bearing exercises (anything from walking to weight-lifting), your muscles become more sensitive to the insulin and your body requires less to maintain a proper blood-sugar levels and less insulin means less fat! That's why you've lost the weight and why calorie restricted diets normally fail. Sure you can lost weight on a "diet" but it always seems to come back if the dieter isn't exercising.
So what you are saying is that exercise increases your muscles appetite for fuel, or in other words your metabolism... fascinating, you really turned that conventional wisdom on it's head!
My take on calorie restriction is that it is substantially harder than exercise. Exercising requires you to be good for a few hours a week, while calorie restriction requires you to be good 24/7. Both exercise and eating right are lifestyle changes, for just about everyone, exercise is an easier one to maintain, and it has other health benefits.
Jim Fixx did die at a fairly young age right after going for a run. What everyone neglects is that by making it to 52 years of age before having a heart attack, he went 17 years longer than his father did... Men in his family died young. period. He lived a lot longer than most of them, and many people attribute that fact to his running habit...
I was a bit over 100 kg (230 lbs) when I started, now I am down to about 165 lbs (75 kg), and my pulse is in the low 40's first thing in the morning... My wife loves the way I look, I feel great, I eat just about everything in sight (4,500-5,000 Cal/day), and I write better code after my mid-day run break... Ask anyone who went from a sedentary lifestyle to an active one about how they feel, and how healthy they are, and you will find similar stories...
I can accept the premise of the article, that conventional wisdom on weight is unproven, but I think that is due to not having done the right experiment yet, not the falsehood of the conventional wisdom...
Personally, I'd love to reach Bjorn Borg's level of cardiovascular fitness; his resting heart rate was between 30 and 45 bpm.
That is a really big range; most people, with years of training, can get their heart rate into the 40s (I have measured mine as low as 39 and I am no gifted athlete, I have just been doing at least one marathon/year for the last 6 years), but it is extremely rare to have anything under 35... I find myself wondering which one of the sources cited in the wikipedia article to believe...
Hell no... The tissue of the hand holding the phones will deform nonuniformly. It would be just as bad as a phone sitting in a car, that doesn't roll or slide.
I ran 7 miles today, during my lunch break. In the last 5 years I have run 7 marathon or longer races, and placed in my age group in multiple smaller events...
I can conservatively claim that the vast majority of baseball _fans_ couldn't hold a candle to me athletically... And it has little to do with genetics (I have no particular gifts when it comes to fitness, I work hard), I take care of my body, most baseball fans don't...
Baseball doesn't make you sweat unless so hot that standing makes you sweet...
The fact that people think it is an athletic activity is part of why the US is so fat... An afternoon of playing baseball is no more athletic than an afternoon of golf.
football, basketball, track and field, soccer... those all make you sweat
Why should one care what order the strokes are penned in for any given character, as long as the character comes out looking the same. It strikes me as a horribly pointless thing to be wasting cycles learning...
I have never penned my O's the way they wanted me to in my mechanical drawing class, except for when the TA was watching, nobody could tell...

Waste heat is still generated, and the radio/tv/headlights draw very little power

Stephen Colbert will be out to get the internet in no time (as as soon as the writers strike is over).
That is good advice for people who are small, but for big folks, like the poster you are responding to, it is a recipe for disaster...

Actually, that is the conventional wisdom.

There is a simple fix for this.
Only allow overrated mod on posts that have a net positive moderation, and only allow underrated on those that have negative.
How a post that hasn't been rated can be modded overrated has always eluded me...
You think that is perfect?
Hell no... The tissue of the hand holding the phones will deform nonuniformly. It would be just as bad as a phone sitting in a car, that doesn't roll or slide.
perhaps you are the dumbass...
You think two humans are going to be perfectly synced up when they shake phones? No...
as long as the shaking you do to the car is small enough that the phone doesn't roll around the passenger cabin, I think you would be fine...
