Introduction to special issue
Getting Better To Get Bigger
David Malakoff, Jake Yeston, Jesse Smith
Science 13 August 2010:
Vol. 329. no. 5993, p. 779
DOI: 10.1126/science.329.5993.779

The end of the age of fossil fuels may be in sight, but what comes after is still a bit of a blur. There are numerous alternatives to coal, oil, and natural gas from electricity generated by solar farms to biofuels brewed from plants. Scaling up these alternative sources of energy, however, has proved a challenge. This special issue explores the progress that researchers are making in developing better alternatives, and the technical, political, and economic pitfalls associated with scaling them up.

Several of the articles are available free this week (according to my Facebook messages anyway) so you can read for yourself what the experts are saying. I'm only posting links to the Podcasts, but the rest are in the link above.

"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther

The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill

It will require massive investment in these alternatives, plus hopefully huge leaps in technology.
Wouldn't it be awesome if a house have 100% of energy needs provided by a 1/2 roof sized solar panel that only cost $1000. It would solve many of the huge electrical grid issues in the developing world and starting to increase in the first world.

Thomas Sowell: There are no solutions, just trade-offs.

If it seems too good to be true it usually is. Not very much info on those links..... We get a review and one paper.

The future is likely foretold in science fiction. It spawns the questions that direct research in the future. Having said that there are a few of things I think. First, improvements need to be made in wireless transmission of electricity. Second, electrical generation needs to come from space positioned solar panels capable of producing power 24/7. Inexpensive rooftop electrical generation is impractical for city use, just not enough power for the population density.

Biofuel is not a viable alternative. Feeding the world population takes precedence. Why should we waste viable farmland to produce hydrocarbons, the very thing we are trying to move away from? It makes no sense. Unless technological breakthroughs to power personal and public transportation and transport of goods happen, we remain stuck with using hydrocarbons. As such, biofuels provide an expensive measure to bridge the gap to the future.

Kinda depends on the source of the biomass for the biofuel, doesn't it Doc? How many pounds of food are tossed out of our grocery stores on a daily basis? How much farmland would some of the experiments with algae grown using the emissions from coal fired power plants really consume? Could we ever replace totally the amount of fossil fuel with biofuel? Not in my opinion, but we really won't be getting non-stop international flights out of a bank of batteries either, regardless of how efficient battery technology becomes simply because of the physics involved, or power our interstate trucking fleet using batteries alone either. We won't even start about the problems using them for trains. Electricity, perhaps, but not from batteries.

We're smart enough to figure out how to make synthetic diamonds and other gemstones, I'm certain we are smart enough to figure out how to make synthetic fuel if/when it becomes necessary.
