How did caveman produced electricity for their objects? like light bulbs, tv, etc?

Question

In those prehistoric times if there wasn't any electricty than how could they light their homes and use the washing machine, and stuff like that?

Answer 1

They lit their homes using the light of the sun and fire, which was discovered by the prehistoric humanoids.  And to wash clothes--what clothes they had--they washed them in a lake or stream and laid them to rest and dry in the sun.  Of course, none of this is backed up by research, but it is widely accepted as the explanation for the times.

Answer 2

ya joking right?!!

Answer 3

How old are you? Cavemen didn't produce electricity and machines wasn't invented then yet.

I don't think you're gonna get a decent answer with that question.

Answer 4

Ha Ha Ha Ha Ha Ha Ha Ha Ha Ha

Was there an earlier pre-dinosaur period of mammal dominance?

How long was it? Was it longer than the one we're in now? Was it as diverse (in terms of number of species) as this period? Were the mammals as large as they are now?

No, not as such. The earliest mammals date from slightly after the earliest dinos; Upper Triassic.

However, mammals are also things called synapsids and, prior to the emergence of dinos, synapsids pretty much ruled the roost on land in most places. They're first known from the Upper Carboniferous (around 310 million years ago), and started to dominate the land by 270 million years ago. That lasted throughout the Permian and into the Lower Triassic.

<<How long was it?>>

30 million years would be about right.

<<Was it longer than the one we're in now?>>

I'm not quite sure what you mean. Mammals really began to dominate things from around the Middle Paleocene, and that was about 60 million years ago. If that's what you're after, then it was a shorter phase of dominance.

The present geological age, however, is said to have begun with the last retreat of the ice caps; something like 12,000 years ago. It was longer than that.

<<Was it as diverse (in terms of number of species) as this period?>>

From what's known of the fossil record, no. However, most species wouldn't have left any fossils. That makes things uncertain.

<<Were the mammals as large as they are now?>>

These non-mammalian synapsids came in a large diversity of sizes reaching up to around five metres in length. The original mammals, on the other hand -known from the Upper Triassic- were all smallings (as most still are). Think shrew to rat-sizes for the general idea. That applies for most of the Mesozoic, although there are exceptions. Most spectacular of the present crop would be the /Repenomamus/ sisters from the Lower Cretaceous of China. /Repenomamus giganticus/ is a dog sort of size, and its smaller sister is known to have eaten a baby dinosaur (fossilized stomach contents). However, those aren't from the 'Age of Synapsids', as you could perhaps term the Permian-Lower Triassic.

Some strange words might help with finding more info.

Synapsids

Early ones = pelycosaurs

Later ones = therapsids

Most interesting among the therapsids could be:

dicynodonts

cynodonts

Both those groups arose during the Upper Permian. The dicynodonts were plant-eaters while the cynodonts became more diverse; meat- and plant-eaters. The cynodonts live on as mammals.

Update

"Yes, there was a pre-dinosaur Period. It was called "Mesozoic Period"."

Apologies, but that poster is very muddled up. Non-birdy dinos lived during the Mesozoic which, therefore, didn't pre-date them, and isn't strictly speaking a period. It's an era subdivided into the periods of Triassic, Jurassic and Cretaceous.
