So you say we have to invest a lot more in solar and fusion technologie to
prevent the world from overflooding because of global warming, and we only
have a couple of decades left to enter the solar and fusion era. Or else we
are f*cked

What about geothermal, water (YES you can use water as “fuel”), or
magnetic?

Really screw up the weather? We would be so lucky if that was the biggest
problem. What about the plummeting biodiversity because of the loss of
habitat for land and marine environments. Or the food and water insecurity
that will face all humans when crops become more and more difficult to
produce, driving global wars.

Solar Cells, sure, but Heliostat (Thermal Solar), work fine. The only real
issue is space.

I’d gladly put out a few solar panels to put a dent in the FPL bill, but
local building covenants won’t hear of it without denying me homeowners
insurance. Also, the solar panels are not covered if a storm damages them.
This is a deal breaker in S. Florida, along with often cloudy weather that
limits the panel efficiency even more.

wouldnt fusion power have even more problems with transportation and
storing then solar ? There will be hundret times fewer fusion reactors then
solar plants so you will need to deliver this power across larger
distances… And if stored – you will have same battery problems

*We will never run out of oil, except oil will become more expensive…*
Although Dr. Michio Kaku appears to believe in solar power, he arises a few
problems that we have to face and one of them, in his opinion, is low
efficiency.

There is a problem with fusion power. Clean energy won’t stop global
warming. It will ACCELERATE it. Because fusion plants will pump water vapor
into the atmosphere. Water vapor is the major contributor of global
warming. But CO2 is the last drop to cause a runaway warming effect. So we
need fusion and solar power that do NOT heat the atmosphere. We have
special air conditioner solar panels now. They cool the homes and radiate
the heat directly to space WITHOUT transferring to the troposphere.

Remarkably short sighted in many ways. In less than two years lots of what
he said has already not followed his predictions, and he leaves out so
much! He talks about oil, but neglects to talk about natural gas, which
has changed the entire picture through fracking. And he does not even
mention the cost of oil wars like Iraq which cost us a trillion dollars! If
we had put a tiny fraction of that trillion dollars into solar and
electrical storage development, we would never have gone into Irag, and the
Saudi’s would have little leverage on us instead of the stranglehold they
now have.

I’m not sure how nuclear fusion would be integrated into the grid as they
would probably suffer from the same problem that regular uranium nuclear
fission plants do today; increasing of decreasing electrical generation in
acccordance with current demand wihich is the reason why nuclear usually
only generate base load electricity with the exception of some plants in
France. And you can increasing the efficiency of photovoltaic cells all you
like but without the ability to storage that solar energy for times of low
production, it’s not really going to matter

already made it price effective to use solar, and they are now world
largest renewal energy user already.

Unfortunately when the oil prices rise, and meet with the lowering prices
of solar tech the international system is just going to flip the prices,
just as they did with the agricultural system of earth. When the prices of
junk food, candy, fast food, and processing food with high fructose corn
syrup went up and met with the decreasing prices of natural, healthy foods
the international system simply switched the prices in order to keep happy
with what they wanted.

I know that. The comments after my original posting discusses that. But
honestly, I’m more interesting in LFTRs becoming the next revolutionary
energy source. Hydrogen is really a negative net gain energy source, what
makes its interesting is that it is renewable; aside from that, it is a
sucky source of energy due to that negative net gain.

If this is 35% more efficient than just PV cells, which are roughly 20%
efficient then the system efficiency is now: 1.35*20=27% efficient… Not
bad I guess, assuming you don’t overheat the PV module by concentrating the
light on it. Maybe stick it to a sterling engine’s cylinder head to convert
the heat to work and get some extra energy out of the system while sinking
heat in the PV…
I’m curious about the material the sphere is made of.
Eric Balcon says:
January 7, 2015 at 1:54 am (UTC 0)
Sorry but this is not a revolution. even if it does concentrate 10.000
times the light, it will be on a single spot, the amount of energy before
and after your device is the same and more precisely a bit less after your
device due to heat loss going through the device, so no miracle here.
The real revolution is to use the full spectrum of the light to generate
electricity with solar panels.

Many are oblivious to the fact there are currently many thousands of solar
powered cars on the road today. Ethanol is a solar fuel. Plants convert sun
light to sugars and starches which is made into ethanol fuel.

I think too many of the folks commenting are missing the point, we need to
work together as a human interface to explore better solutions, people !
LISTEN we are killing our planet we must act now to reduce pollution,and
produce enough energy and food for humanity.To those who want to continue
using coal and nuclear energy,you must not live near where coal ash spills
in drinking water supplies and constant warning sirens of local nuclear
plants effect your daily life!!!!

There are other problem with the facts int he video too. By focusing the
light energy onto the solar panels the temperature is increased and the
efficiency decreases.
As the position of the sun changes, doesn’t the amount of energy hitting
the PV panel change? Seems to me it would be just as efficient to have
multiple solar panels pointing in different directions than one polished
sphere.
Why do they knock nuclear? It’s clean, and in the terms used in the video,
“renewable” (yes I know neither one is), but it’s 100% natural and doesn’t
pollute when recycled.
I would think he would want to compare it to coal, which is contributing to
global warming, global dimming, and his killed more people and polluted
more land than nuclear.

Ridiculous crap. Fresnel lenses are a lot cheaper than perfect glass

all the other tracking concentrator schemes. If you want it windproof build
it tougher or put it under glass,

There is a basic logical fallacy here. If you take the solar energy
falling on a square meter of the earth and focus it on a smaller area you
have reduced the size of the solar cell required to collect the energy. But
you still need the square meter of sun light. It is only an efficiency
gain if the whole apparatus (square meter of solar cell versus small cell
and focusing apparatus) is cheaper or involves less resources than the
other.
I suspect that on this basis the square meter of solar cell wins over the
“ball” lens and solar cell.
CharlesDourdy says:

pet peeve here, maybe I’m a grammar a$$hat, but solar is not “renewable”
energy. There needs to be a cycle for something to be called renewed.
Unless we find a way to put matter back into the sun to be used as fuel for
further solar reactions and re-radiation, then there is no cycle, therefore
not “renewable”.

There is a different way of designing it… make the crystal ball smaller
into individual ones then hook up fiber optic lines from the crystal ball
mini’s all the way down towards the solar panels… it just that I don’t
like the idea of a huge crystal ball hanging over my head if it falls
through the roof of someone’s home then that person would be injured but
the basic design makes sense tracking the sun without tracking I liked it
ever since I saw it
