How does FV translate to PV, PV translate to FV, go back and forth and become very familiar today.

These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.

So, here's the first thing. At this point, we'll typically call this a PV, present value. Then the number of periods are pretty obvious.

So, in the, in the, in the beginning what I will do is I'll just take PV and I'll try to relate it to FV.

But new investment just in solar PV was around 89 billion in 2010.

In fact, PV prices are set to halve again this year.

These PV systems were usually installed on utility grid connected buildings in areas with centralized power stations.

Our idea for the bid was 100 percent solar cooling, based on the idea that we use the roof of the stadia, we cover the roofs of the stadia with PV systems.

like putting solar panels on a roof, and the next thing you know, you have a neuron which can be activated with light.

With the advent of smart grids and free market pricing, solar PV seems well positioned to provide solutions that are quick to build and scalable.

So this mouse was blind a couple weeks before this experiment and received one dose of this photosensitive molecule in a virus.

So going back to what I was saying before about all power being produced well, other than photovoltaic being produced by this boiling of steam and turning a turbine, that's actually not that efficient, and in fact, in a nuclear power plant like this, it's only roughly 30 to 35 percent efficient.

When blue light hits it, it opens up a little hole and allows charged particles to enter the eye spot, and that allows this eye spot to have an electrical signal just like a solar cell charging up a battery.

Until recently, photovoltaics were most commonly used in remote sites where there is no access to a commercial power grid, or as a supplemental electricity source for individual homes and businesses.

He obtained a doctorate from the University of Göttingen in 1888, and from 1900 to 1913 he was professor of theoretical physics at the University of Heidelberg.

Since 2000, global onshore wind power generation has averaged 27 annual growth, while the growth rate for solar photovoltaics has been a staggering 42 .

Since July 2006 France offered the highest incentive for BIPV, equal to an extra premium of EUR 0.25 kWh paid in addition to the 30 Euro cents for PV systems.

Although silicon s light absorbing properties are suitable for photovoltaic devices, the near 0.5 volts that it generates is too weak to split water in a solar fuel generator.

The neuron uses its natural protein making machinery to fabricate these little light sensitive proteins and install them all over the cell, like putting solar panels on a roof, and the next thing you know, you have a neuron which can be activated with light.

And PV installations are forecast to rise further this year, by perhaps 20.5GW, taking global capacity to around 50 GW the equivalent of around 15 nuclear reactors.

We're going to take these blue light photosensors and install them on a layer of cells in the middle of the retina in the back of the eye and convert them into a camera just like installing solar cells all over those neurons to make them light sensitive.
