No, Peltier is very inefficient.

There must be a better substance then?

Nope, we've been doing that stuff more more than a century now.

Peltier isn't used much.

Because its much worse than compressor for all but the smallest heat
pumps.

Same as batteries,

Nothing like it in fact.

we've been using them for ages, but only recently have we bothered
looking
into different substances to make them more powerful so they can be used
in cars.

That mangles the real story utterly. We have in fact been looking
for better batterys for more than a century now and it wasn't
electric cars that turned up much better batterys.

What was it then?

Laptops and cordless power tools.

Nah they were fine. Cars however need way more power.

It seemed to happen around the same time.

Nope.

Yes it did.

Nah they were fine.

Like hell they were when we only had lead acid batterys and carbon batterys.

Cars however need way more power.

And still do.

Nope, long before.

Another retarded "conversation" between Birdbrain and senile Rot:

Senile Rot: " Did you ever dig a hole to bury your own ****?"

Birdbrain: "I do if there's no flush toilet around."

Senile Rot: "Yeah, I prefer camping like that, off by myself with
no dunnys around and have always buried the ****."
