Sounds great. I will believe it when I see it.

What we needed was a crash program 10-20 years ago with the funding and support of the federal government (since only an organization that size can provide the financial resources) on the scale of the Apollo Program or the Manhattan Project.

Unfortunately, mankind seems almost hard-wired towards short-term thinking. (I would be interested to see what Diploid says on that subject).

It does not look good. We are about to go through wrenching change.

How about a fucking link?

I think this is the article he's talking about (attached). If not, someone tell me the issue it's in and I'll put it up.

I've only skimmed over it, but from what I've seen so far, it's wildly optimistic, particularly about the potential for solar energy.

I didnt read the article, but if what you find strange is the efficiency of modern solar cells, I can definitely back that up. Expect solar cells with efficiencies of 60+% in the not too distant future.

The theoretical maximum efficiency possible, could all of the energy in the sunlight be turned into electricity by a solar cell, is 34%.

Here's what I find optimistic.

Full-on noon sunshine at the equator yields about a kilowatt per square meter.

Even if we somehow manage to invent hyper-efficient cells at 60% (current technology is only about 30% efficient), that's ~600 watts per square meter. Move from the equator to 45 degrees (northern US) and you end up with sin(45) * 600 ~= 420 watts per square meter on sunny days at noon. The power drops off rapidly as the sun moves away from noon.

The average US home consumes 10,000 kilowatt-hour per year* (27 kWh per day). So, solar can help, but it's definitely not the solution.


BTW, this next bit is off topic, but interesting:

In his documentary, the former Vice President calls on Americans to conserve energy by reducing electricity consumption at home.

The average household in America consumes 10,656 kilowatt-hours (kWh) per year, according to the Department of Energy. In 2006, Gore devoured nearly 221,000 kWh — more than 20 times the national average.

Last August alone, Gore burned through 22,619 kWh — guzzling more than twice the electricity in one month than an average American family uses in an entire year. As a result of his energy consumption, Gore’s average monthly electric bill topped $1,359.

Since the release of An Inconvenient Truth, Gore’s energy consumption has increased from an average of 16,200 kWh per month in 2005, to 18,400 kWh per month in 2006.

Gore’s extravagant energy use does not stop at his electric bill. Natural gas bills for Gore’s mansion and guest house averaged $1,080 per month last year.

Then again, hungry radiators and airconditioners need a lot of energy. Something I can do without.

I have managed to get my own power consumption down pretty good. Electricity is getting darn expensive now when they have unregulated the power market.

When people speak of efficiencies for solar cells they mean the power on the cell vs the power out for the most part. There is a theoretical maximum for a basic PN junction however. But an obvious adjustment someone figured out was to have a multi junction where you create different band gaps or traps in the bandgap. there are many variants on the design going on at the moment, including nanotubes, quantum dots etc..

Yea I agree with the limitations of solar cells. They should merely be used in conjunction with other technologies

10 kWh per year. That was a typo. Al Gore apparently lives in several mansions.

A chart I found.

they're billions. would take too much time to count :smile:

we should rig all the deserts with solar panels and wire them to a huge condensator. problem solved

Interesting... I haven't followed the field in a few years now.

Because they are not considered a developed country. India is missing for the same reason.

1217W/hour???

That's not very much...

The furnace fan at my mothers house is a 1.5kW motor, for example. Any type of electric heater is going to use over 1000W. The window A/C unit in front of me (a small one) uses 845W.

Turn on a few things in a house...and you'll be using more than 1200W/hour.
