5 Inventions Showing Us the Future of Solar Energy

5 Inventions Showing Us the Future of Solar Energy

When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.

Isn't window glass made silicon anyway? So why would photovoltaic glass need to made of something else?

The future is plugging your phone into a picnic blanket and it starts charging

Elon Musk's solar roofs look pretty good. https://www.tesla.com/solarroof

1:43 seconds into a 10 minute video and I'm already seeing huge problems with this Agrovoltaic system. Chief amongst those problems is relying on water vapor to keep you cool. If you're a hater of GHGs then you should really hate water vapor as it is the absolute worst GHG of any GHG including all anthropogenic types of GHGs. Obviously those panels won't be much more efficient and 3% gains really is worthless especially when you need that energy now like say to run those ventilators in hospitals. Would you preferably them to be powered by solar, wind, coal or nuclear? I know my two choices aren't renewable, but those non-renewable options would save your arse all the same if you needed to be on a ventilator. All the sudden green looks red as death.
But let's continue…
2… Bruh this isn't new tech at all and as explained they require electricity to run electricity that is taken right off the top for any solar array.
3… Sounds nice still a pipe dream but hey this is looking towards the future and there might be room for significant improvement of the technology. Additionally

4. This tech in cloths is a waste and likely going to create much more hazardous waste than anything. In awnings and things like that it may be more useful but only just ultimately I can't see this being super useful for me personally, but hey others might be able to use this far more effectively. Again room to improve the tech possibly (I don't know how this particular fabric photovoltaic systems functions).

5. How does this work? Not sure at all the explanation was nonsense sounds like you need to use energy to pass this fuel through the filter. Perhaps that is just gravity fed? Checked the paper… It's not just fed by gravity it requires 2 thermocouples and a vacuum. So yeah its not energy neutral just operating the mechanisms to keep this closed system functioning requires another form of energy which may or may not be green and/or renewable. Additionally in the here and now they're using expensive materials like Platinum in their catalyst and hazardous elements like Cobalt as well. If this stuff leaks into your water or air you may get very very sick. At least solar panels don't make people sick as their hazardous chemicals stay inside the panels even if panels are damaged.

Imagine a farmer trying to harvest just crop with a ton of solar panels in the way.

Tim McDaniel says:

About solar windows: The human eye can easily adjust to different light levels. I was astonished to find that the skylight in my dining room passes only 10% of the light hitting it. (E.g., on a cloudy day, 1400 lumens when outside the same device measures 14,000 lumens.) So 50% tint may not be any problem at all.

Jmack1lla says:

If they have the money to make these panels in the first place why cant they just watet cool them like pc? Doesnt sound exensive or hard to engineer..

Andy says:

There is no future for solar energy except for in space. Too expensive to make, run, maintain and unreliable also deadly. Nuclear, coal and thermal energy is the way to go until cold fusion or similar is available .

Eneov says:

What time is it? Cyberpunk time! Later this year..

Blaze says:

We need an orbital ring like in 00 Gundam

scottabc72 says:

#5 seems the most exciting when you think about the fact that the main problem with solar energy is actually storing and distributing it. We have the technology to now to easily generate all the power we need from solar but we do not have ways to economically store and distribute it over long distances, sounds like solar thermal fuels could go a long way to solving this.

fuck you says:

concentrated solar thermal!
concentrated solar thermal!
molten salt!
hot oil!
the only actually sustainable solar energy!
the only solar energy without a storage problem!
just build a big reservoir of hot salt!
the only solar energy that won't disrupt the grid!
these would pair great with molten salt reactors (and high-temp gas reactors!)

Jeska says:

Solar glass used for greenhouses, powers air circulation (and possibly water pumps) for the greenhouse.
Seems like a win-win situation there.

Wade Haden - Master Jedi Engineer Goth says:

its time to abandon oil since its a bankrupt industry.

EspHack says:

4:21 …. carboard houses!

DoctorX17 says:

I like thermal solar power — use the sun's heat to, say, boil water and power a steam piston

Philip Lindley says:

No-one has yet solved the economic problem of build, install and maintenance over a lifetime being very similar to cost of electricity produced.
That is the biggest bugbear with photovoltaics.

James Berend says:

The future of energy is nuclear

Aaron Simpson says:

Not gonna mention solar city??? Aight.

Chris Ellingson says:

3:55: Most ganged single axis solar trackers use far less than 5%. The actual figure varies array type size and actuation, but the tracker system would use <.1%. Designing PV tracker control systems is my day job.

JNCressey says:

Solar freekin cropways. just another example of how putting solar under the road is unnecessary.

Silberzunge says:

if idea 3 absorbs mainly infra red light isn´t it cold in the rooms ?

Sameer Choudhari says:

All these researches on one side and Covid vaccine rules them all…… WE NEED A VACCINE!!!!!!!!!!!

Them giraffes though
