Will this be tomorrow's transportation?

Guess those submarines are a figment of our imagination?

The periodic table has had some new additions.

What submarines ?

Shoot, why didn't anyone tell me, I want my free liberal arts degree now!

I think one thing important thing that hasn't been considered is reducing our dependency on foreign energy sources. The electric car is perfectly suited for this since you can drive generation from solar, natural gas(which is much cleaner than coal and currently transforming the energy generation industry), etc. Heck, I know more than a few people who run their electric cars 100% from the solar panels on their roof.

In my mind Tesla could be the modern American muscle car. You have a car designed in America, built in the US and growing the number of manufacturing jobs domestically. It's a company that has entered in incredibly difficult market and yet now builds one of the fastest production cars in the world. How can you not love a car that can put down over 1,000hp and is also a great family car(seriously they're incredibly roomy). Yes they had help from the government, but what industry hasn't? All of the things they used were available to other companies and today the ZEV credits/etc make a pretty small portion of Tesla's overall profits.

Sure, battery prices are high now but what many people don't consider is that batteries are a technology, not a resource. When economies of scale kick in they get orders of magnitude cheaper rather than more expensive due to scarcity. Just look at the price of HDTVs over the last 5 years. All of the physical components are readily available, it's the precise manufacturing process that's expensive. Just like the chip in your modern computer starts out as sand just(silicon) same with Li-Ion batteries.

To me they're a marvel of American thinking and engineering. I think that's something we could use more of these days, I'd much rather take that then companies that are moving production out of the US.

Economy of scale has kicked in with Lithium batteries a long time ago. The last major drop was when production was transferred to China. Lower wages, no pension, no healthcare plan and no environmental regulations so the toxic manufacturing process poisons the environment.
Lithium batteries are not getting cheaper. They have bottomed out like microwaves, calulators and big screen TV's.

What submarines ?

The ones that have hydrogen fuel cells!

Another great point is how Tesla (aka Elon Musk) has driven down the price of batteries. Tesla motors has all but forced the other OEMs to start producing electric vehicles... QUADRUPLING the economic investment in high capacity batteries, and driving down the price per kWh hr by nearly 80% of what it was ten years ago. This has also driven technology to develop smaller/lighter packs as well.

In the next 20yrs, we are likely to see electric energy storage density increase by a whopping 1,000%. Just to give you an idea... that would be the equivalent of advancement we accomplished from the period of the Baghdad battery (around the time the Great Pyramids of Giza were built) to the mid-90s (NiCad rechargeable batteries). That's THOUSANDS of years in advancement in only two decades. UOTE]

There is no 1000% increase in battery storage density, there are no elements on the periodic table that can react together an store or produce that electrical storage energy density.
Tell us please what chemistry and physics courses that you graduated from in highschool, college or university?

That happens before you generate the electricity with it... Think about it... Case closed. All electric does is move the exhaust or emissions and much more of it, to a different location, at gigantic cost, and increased emissions. Case closed. HS

You mean the power stations use the same fuel as a Diesel engine? Case not closed!

Speaking of electric transportation.......check out the new JD tractor.

John Deere痴 first fully electric tractor sounds like a jet engine

Tell use how long that 130Kw hr battery pack will last before charging ? Don't waste your time telling us that new batteries "are just around the corner".

The ones that have hydrogen fuel cells!

Still don't have the range of nuclear. Hydrogen is explosive.
As for endurance the 2-1/2 weeks is with limited movement, using snorkel air, with minimal electrical loads beyond operating a gps, radio and a microwave to heat up canned food. Big deal, that is done now with lead acid diesel electric subs.
Trying to make subs green to suit the greenies and peace lovers is not practical for the poor smucks inside the sub.
The hydrogen sub is just another version of the current diesel electric. Empty out that diesel tank an she ain't going nowhere.

The new nuclear subs never require refueling...they are fueled from the onset for the 30+ years of expected service...they are only limited by the amount of food they can carry in their stores...

Lmao

Apologies for too many zeros.

Regardless... investing in more efficient ways to use electricity as a fundamental source of power for locomotion, will yield far greater benefit than what little bit of progress is left in combustion engine deveopment.

Aw shucks B&D; it seems your knowledge base is out of date.

The nuclear subs do have endurance and they do need it if they are trying to find a hydrogen fuel cell sub.
