Hyperefficient solar panels

Biochemists have long known of examples in the wild of structures capable of converting light energy into chemical (stored) energy with extremely high efficiency - figures of 90% or even 100% have been knocking about (with important caveats - e.g. this figure depends on the light being of the right wavelength, etc).

I’m of the firm belief that when it comes to structures and devices, what nature evolved, humans can in time approximate or perhaps even improve upon by design (though when it comes to complex systems like the human cell - in extraordinarily complex and interlinked homeostasis - it’s borderline impossible to design from scratch).

So what happens to society when hyper-efficient photovoltaic technology arrives that allows us to ‘mine’ the Earth’s one and only energetic input with >90% efficiency? We’ll be able to power our lives without relying on digging up pre-existing energy stores.

That day could bring a technosocial revolution of the likes we haven’t seen in a long time, certainly since the invention of the Internet.

It’ll almost certainly affect the balance of power globally and within a country’s society, government and markets. What’s more, if it changes how we power our lives - which it would, if it brings power generation and usage closer together, into the hands of the citizen, not as currently remote as a distant power station - it may also bring about a radical reappraisal of our lifestyles and the energy demands of the different parts of that lifestyle, each with wildly different importance to our survival, progress and happiness.

Just think - and let me know in the comments - how your life, and the society and government around you - could be different if power generation was a) not dependent on stored sunlight-derived resources (include nuclear) being dug out of the ground; and b) if you generated all/most of your power yourself/as a neighbourhood co-op. Also have a think about what needs to change - infrastructure, legislation, baseline attitudes, auxiliary tech - before that day can arrive.

Happy (energetic?) independence day.

Energy
(just did some reading on means for capturing sunlight and how efficient they are; it challenged some of my preconceptions of where the solution might lie, so I though I'd share it with you guys too. I omit energy sources that are many thermodynamic steps removed from incident solar radiation, like hydroelectric, wind and waves - I *assume* these are extremely inefficient converters). Chlorophyll (in plants, converts sunrays into 'redox potential' - useful chemical energy that can smash carbon dioxide and water together to form hydrocarbons - like sugar or biodiesel): ~100% Conversion of chlorophyll-derived energy to useful molecules, like sugars: 50% Factor in the energy spent by the plant so that it can live, and the sunlight reflected off the leaves, and your big green plant could theoretically convert just 11% (other sources quote 34%). Sugar cane is at the top end of the ones that have been measured: 4%; corn is 0.5% (corn is a major crop being used for bioethanol); wheat is 0.3% Solar panels: 20% Algae: 13% I'd also like to know what the energy efficiency of a snickers bar or a sausage is (in terms of energy used by plants to make the individual components,...
Microbial fuel cell not just a hydrogen creator, can also generate electricity
I keenly follow latest breakthroughs in biomedical science, neuroscience and bionanotechnology - I figure I could share some of that on this blog, if it's something you'd like to see more, please let me know. The Fuel Cell Bacteria: not only can Rhodopseudomonas palustris use light to create hydrogen, it's also got an amazing superpower: munching on either volatile acids, yeast extract or thiosulphate, it can actually generate electricity (without the need for light). An R. palustris culture in a Microbial Fuel Cell (MFC) generates roughly 2.7W/m2, so there's ample room for improvement (your average solar panel in the United States delivers 19 to 56 W/m2).  Scientifically, this is a fascinating discovery - the team's going to have a lot of fun (don't laugh!) picking out the different metabolic modes in this bacteria capable of producing either hydrogen or electricity, and from loads of different inputs. Those landfill mountains of trash could be much less of a pain in the ass in the not so distant future... we may even be thanking this current generation for throwing so much good energy out (even if they curse us for impoverishing the Earth of a better fuel, namely petroleum)....
WTF-of-the-day: Friday 30th May ‘08
A US cleantech company called Blacklight Power has raised $60m for a new, very clean form of electricity production. Nothing astounding there, really - cleantech is very much du jour. What's "WTFotd"-worthy about this story is that the technology they claim to have developed runs against a key part of quantum physics: they claim that they have discovered a lower energy level for electrons than the 1s shell resting state: the hydrino. To the layman: hydrogen has been extensively studied because it's the simplest periodic element, and when you're talking quantum physics, studying basic, simple systems helps... a lot. So physisicts think they understand it pretty damn well. A fundamental tenet is that the lowest energy 'shell' (think of it as an orbiting satellite around a planet) that electrons can take around a hydrogen nucleus is called 1s. This is the 'resting state', and most physicists don't believe it could be pushed any lower. *If* it could, then you could take out the difference in energy, use it to power a plant. But physicists believe that hydrogen electrons can't go any lower: try to squish it in any closer, and it will just press back; so the only energy you...
