Longer-lasting lithium-ion

[Into the Night]

No, fucktard, it's a technological reveal in a science newsletter. What Rachel Maddow does is OpEd, this is not that, you uneducated lot lizard!

Your racist fucktarded ass started howling to the moon about China or some shit when the dude's Australian, you ignorant prick.

Know your role. You're nowhere near on my level, boy.

It makes little difference these days, since Australia is currently an oligarchy moving toward a dictatorship.

That doesn't help with manned space stations and vehicles.

These typically rely on solar panels and depending on the location of the station or vehicle you can get solar power 24/7.

Why do you think batteries are used in space instead of fuel cells?

Because fuel cells require fuel. Batteries can be recharged by solar which is far more practical IN SPACE.

What is your recommendation?

If none, then all incremental improvements are welcome. Our past 10,000 years of history have been incremental improvements in areas like domestication of livestock, agriculture and metallurgy.

I'd hope to have a Jetpack and a Mr. Fusion by 2022, c'est la vie.

He is not making a recommendation. He's simply realizing the fundamental problem with all rechargeable batteries: You still have to charge them. It still takes a long time to charge them.

if you want a jet pack you can buy one today. Don't expect to stay in the air for much longer then 30 seconds.
Fusion, of course, has a long way to go before it's controllable (other than a bomb). Fusion also produces high speed neutrons, which are not stopped even by thick lead. The can be stopped by a sufficiently large water jacket around the reaction, though.

Such a car would effectively be a steam driven car.

In deep space and not too far out. Only about half their time in orbit is in sunlight. Only two weeks out of four of daylight on the Moon's surface.

A single battery cell's energy output is determined by its size. Bigger has more storage capacity. It's that simple.

Am referring to energy available per square surface area of anode and cathode. Yes...larger batteries are capable of storing more energy, but again, you have to 'fill' it from somewhere. It's just a bigger bucket.

The amount of charge in determines the amount of power you can pull out of it and is limited by the size of the cell.

Again, I am referring to energy per square area.

More cells = more available power or more available voltage. Connection in series (more voltage) or parallel (more power) determines this.

The problem with the low voltage of batteries is that if you don't raise this then all the wiring and components in the system you have get big FAST. That adds weight and cost to them.

This weight problem you mention is correct. It not only adds weight and cost, but bulk.
There comes a practical limit when it comes to designing any vehicle that has to carry the darn thing.

Spacecraft do not necessarily have solar power available to them. Deep space travel takes you too far away from the Sun to make solar power essentially useless. Further, travel with a solar power hanging way out in space makes maneuvering difficult since acceleration like that can easily damage solar panels.

Spacecraft make use of fission power pack (Pioneer used plutonium), fuel cells (most practical for spacecraft that have to maneuver), batteries (another option, but heavier), or, of course, solar panels (useful for static stations with little or no acceleration other than a smooth orbit; and that close to a nearby sun).

The Apollo program used a combination of batteries and fuel cells. Solar panels would've been completely impractical, due to the need for the spacecraft to maneuver.

Not a space craft. A moon base.
Solar power (with ballast) can certainly work. It is not due to orbit. It is due to rotation of the body in question (the Moon). The only obvious exception is a Lunar eclipse.

Such a system is extremely expensive, but since there is no fuel on the Moon (that we know of), there is little in the way of options.

The Moon is not in deep space.

Wow, Sybil! I'm surprised you were able, barely, to follow the conversation. Kudos!

Fusion is not viable, next!

Steam is kind of practical but complex:

A 1925 car capable of 75 mph + with a 200 to 300 mile range and meets current California emissions for motor vehicles...
