I just dropped the price of
the permaculture playing cards
for a wee bit.

 

 

uses include:
- infecting brains with permaculture
- convincing folks that you are not crazy
- gift giving obligations
- stocking stuffer
- gambling distraction
- an hour or two of reading
- find the needle
- find the 26 hidden names

Thermoelectrics are just smoking the last couple months!

preprint again for this

http://arxiv.org/abs/1203.0161

and some discussion with the guy that wrote it down in the comments.

physicsworld.com/cws/article/news/2012/mar/08/graphene-in-new-battery-breakthrough

just put this up for the geothermal question

Can we buy graphene like this, or is this yet another energy discovery that will never make it to the general population?

It would be great if we could get our hands on this stuff and make something useful for ourselves.

You can buy graphene oxide, put it in an ultrasonic, and bond it to copper, by putting it in a carrier fluid, and running a low current thru it. Makes it an excellent conductor.
On youtub , look for "making buckets of graphene at home"?

You can make it on materials by flowing methanol over the substrate , with current flowing thru it. fire hazard warning. IF correct config of edge structure, it is room temp superconductor.

You can sputter it on with CVD, but need to do it in a vacuum chamber.

China is now shipping graphene coated aluminum foil.

If you put it onto ribbons of foil, and put the foil, and free graphene in water, it will self offset to form a storage battery, just don't shake it. No studies out yet on jells....

My homework shows that you should be able to coat copper sheet, burn in conductive paths with a laser, and have homemade solar panels. and a fireproof roof

And the video on this

another thread said graphite oxide is 150 per 500mg. Not so, you can buy straight graphite from locksmith supply, bearing manufacturers etc, for 35 bucks a pound. Then put it in a jewelery press, or a ball mill, and any compression will create graph oxide from graphite.

here is the link to the methanol graphene paper, just put it up at Hackaday too

A true home made solar panel from scratch? Now, that I would be interested in doing. Ditto with a battery that would hold a useful amount of energy.

I'll be going through those links soon. Thank you for the info.

Reading my earlier reply, I sounded pretty cynical. Granted, many of the so-called breakthroughs I've read about never made it to market, but I didn't mean to sound so negative. Got to remember to keep positive about this sort of thing.

Well, well.

Looks like InGaAs self assembles on a graphene substrate.
This builds self assembling solar panels, and perhaps microelectronics.

This might also build "wells" that can trap IR energy, not just visible light. This happens in nanotowers, because the photons bounce around inside the "forest", and slow down enough to drop into the holes, upping the overall efficiency.
You can also grow carbon fiber nanotubes on graphene, because the attachment points correspond to the edges of the 6 sided graphene.

Not graphene, but could DIY this type

New graphene ribbon and tin oxide battery design looks good.

Two days ago Vodophone announced through Giz mag (azine) Their 'power pocket that charges a cell phone thru elect cord connections to the 'power pocket'!
no mention of graphite batteries or price in my RSS www.gizmag.com/power-pocket-charger27914/
