solution to the energy storage problem!
thumbs up?

Or we find a way to power solar cells using mirror on the moon to reflect light, or just the light already reflected off the moon!

yeah maybe

aww well maybe in the future they’ll be more efficient ^-^ always thinkin positive

batteries are much too inefficient im afraid

that really isnt communism, i get your point but no, just no.

Japan’s Space-Based Solar Power project would have been an interesting addition (or follow-up?) to this topic.

BUT, what is the price of global warming or just the damage we are doing to the planet with an oil power plant. it may costs in $ half of a solar power plant, but it may actually costs us more in ecological disasters.

Problem with your statment about spending more money on things. They put up wind turbines which are far more expensive then proper power plants and produce a fraction of the energy. Main point we should have gone nuclear and we didnt cause people were too stupid.

option 2, GIANT CAVERNS UNDER INSANE PRESSURE! that would be so cool!

At the level I was doing, it crossed over with physics a lot, and there was many chapters on solar and photovoltaic [x

not a whole lot of chemistry in this video…

…. Why didn’t I see this before I sat my fucking chemistry exam, IT ALL MAKES SENSE NOW ;(

why do Americans say turban instead of turbine

that is called communism, and no, it does not work like that

0:37 *facepalm*
watts are used to measure the rate of energy; they are joules per second. A 100 watt light bulb uses 100 joules of energy every second. You probably pay your electrical bill by the number of kilowatt hours (kWh) you’ve used, which translates to “kilo (1000)s of watt-hours (joule-hours per second)”, or 1000 * joules * the number of seconds in an hour (which is 3600).
TL;DR: 1 watt (rate energy) = 1 joule (energy) / second (time), and 1 kWh = 3.6M joules

you’re definitely one of the few people making science more accessible (and proving it can be fun to learn) for people. Thanks for doing that.

I heard something about new technology allowing use of DC instead of AC in world-wide networks which would decrease the loss of energy. Maybe then we’d be able to use solar energy 24/7.

In Popular Science, there was something about energy storage, where it was like… a glass cylinder with like a centrifuge, except with brushes, and the power sent to it would spin it, and the vacuum would store static electricity for future use… and people were experimenting with it!

That’s usually what happens, like most things you use, they become more uneffective the longer you use them.

… how about charging a battery?

sooo who exactly controls how expensive stuff is??? exactly. id say if people cared more about efficiency than money, then we’d be hundreds of years more advanced, in alot of fields not just electricity.

if the electrons get knocked off can it eventualy rum out of them and stop working as a photovoltaic cell

Wow all of that and… You know the sun is very, very, very hot, toasty even. Which makes bulitbull12 statement all the more of a joke. We could have 5 times the amount of metal need to cover the mass of the sun, see-through panels to let the light out and all of that wouldn’t matter because the sun would incinerate them… hence joke. Unless it wasn’t a joke then I think I just found me a high paying space job with free dehydrated ice-cream
