Never understood why the omnimech was supposed to be such a big deal... The battle master carried a ppc around in its hand for centuries.

Inner sphere refits took hours to days, omnimech upgrades were supposed to be something for which you'd just roll up a big truck or walk the 'mech up to a gantry and swap weapons in minutes. So omnimechs could be customized for each loadout but not IS 'mechs. All 'mechs are limited as to their maximum carrying capacity in-hand.

The F-35 airframe is mostly just a shell around the modular components, which already come from many different companies.

The airframe is a major component just like our skin is a major component. Not only does it hold the other components in, but in this case it's also responsible for the primary distinguishing feature of the aircraft. Redesigning it to fit new stuffins' would be nontrivial, though feasible.

Israel is probably close in technology, training and experience. Good thing as far as fantasy matchups go that they are not raving, frothing maniacs

Ethnic cleansing.

and have no industrial manufacturing base.

Yep, they're not dangerous to anyone without our help.

The traction control system should kick in when the tires _actually_ lose traction. If they programmed it for an estimate of the traction of new tires on dry, clean pavement they're doing it very, very wrong.

Tee hee. You're hilarious. If they know that there is wheelspin every time they deliver a certain amount of power to the motor when the car is in a given condition then they can achieve better traction by simply not doing that. Just like your PCM's LUT won't deliver simply any arbitrarily high amount of fuel no matter how much it's trained because there are limits built into the code from the factory, a good traction control system will always* avoid putting out more power than it knows the tires can handle. And in fact, every EV worth more than two cents which is capable of breaking the tires loose does not put maximum power to the motor right away, whether it's a Tesla or an R/C car.

* OK, not always, some vehicles are meant to have wheelslip.

Because in other places 'democracy' is not just a slogan,

usually because it was not something took for granted.

Every day you're not doing something to improve your lot, you're taking it for granted. Most of us are guilty. But this is all irrelevant, because this is based on the opinions of the people writing the report, and not of the citizenry of the various countries.

Comment: It should start later, esp. for high schoolers (Score 5, Insightful) 123

No need for school to start at the absolute butt-crack of dawn. It's actually been shown to be harmful for teenagers. Their natural sleep cycle involves sleeping in. Many of them simply physically cannot function so early in the morning. (Thinking is a physical process...)

If high school started an hour later, the kids would be on the streets less while parents are off work, too. So it seems like a win-win, without actually increasing the number of hours of instruction.

Increasing the duration of school won't automatically improve education. "No Child Left Behind" certainly didn't, but it did require greater duration to the school day if you actually met all of its requirements.

What about a motorcycle's range? Are these vehicles not ready for prime time?

Of course not. Motorcycles only fit the needs of a minuscule segment of the population, they are not and never have been a "prime time" [equivalent] type of vehicle. They also get poor mileage (for their mass, especially, but many of them actually get poor mileage on the small car scale now, since small cars have come so far) and they have high pollution except in the few places where catalysts are mandatory. Even then, you can expect more pollution per gallon burned.

They also have new tires, which improve the rolling resistance coefficient by about 20%.

Do they mention that the minimum stopping distance has now increased by 20%?

Every year, tires get better. They can probably get the same level of traction with today's LRR tire as what they had before. We bought this year's best All-Terrain (Cooper AT3) which has finally solved their wet traction and tire wear problems, but it still has awful tire noise in turns, makes you think a wheel bearing's going. In a couple more years I expect them to have solved that particular problem. LRR tires have come a long way too, and there's a whole new generation of them now to fit into the space they used to occupy, for the cars least expected to handle well.

"assuming you don't have antilock brakes" is irrelevant to any vaguely modern car, because the EU made ABS mandatory years ago

So did the USA. And the USA has also made yaw control and traction control mandatory since 2010. As usual, the USA has more strict requirements for new cars than anyone else in the world, both in safety and finally now in emissions and mileage. (The USA has the strictest emissions laws sometimes, but not all the time...)

Worse in the winter cause you're blasting heat? Why not just put a coat on?

People don't buy an $80k car so that they can wear a heavy coat instead of turning on the heater. People who can afford them just move closer to where they want to go in order to defeat range anxiety. #poorpeopleproblems

In fact, strike that, this is simpler. Have your solar cells pump water to the cistern for all the hours the sun is in the sky. Have a separate pipe in which the water flows down hill to spin the turbine, which is your power source. The cistern acts as a ballast, storing energy during peak production times to be used during times of low or no production.

The electric motor which pumps the water might be 95% efficient, but you have to use it to fight gravity. Or you could just not have any conversion loss at all, and not fight gravity, when you're actually using the power. And that's why this is a dumb idea.

Owners might want to take a close look at the NHTSA testing of the tires. Generally speaking, lower rolling resistance means less traction, which means less safe when cornering, maneuvering around an accident or animal ahead, or braking.

Sure, although they could have updated the traction/yaw control software to account for the reduced traction as well, and may have done.
