Free Energy: Solar and Dynamo LED Keychain Lights

Last year, one of the vendors at NESEA's Building Energy conference ( gave away a keychain fob, a little two LED hand crank light.  This year, another vendor gave away three LED solar keychain lights.  A few weeks later, I got another solar LED light as a giveaway from the MIT Energy Initiative.

A little searching found where these promotional gifts are available in bulk:
1.61 @ per 5000 solar keychain lights

1.32@ per 5000 hand crank keychain lights

I wonder what happens when these cheap sweatshop trinkets meet the necessary invention of the bottom billion and a third, billion and a half people who do not yet have access to reliable electricity.

In 1988 I visited China.
One evening, I walked out of the White Swan Hotel
on Shamian Island and crossed the bridge
into the city of Guangzhou.
There I saw a line of men
standing behind small folding tables
in closed shop doorways.

Coming closer, I saw that they were rebuilding and
plastic "disposable" lighters.

I want a solar rechargeable reading light
just as cheap, adaptable, and readily available
as a disposable cigarette lighter.
We need to make it possible
for every child around the world
to read in bed
and dream.

That's one way we could transition to a more renewable economy.

Solar powered stuffs are really cool but we have to admit it they are quite expensive in a way. One of my friends gave me a keychain like this well it lasted for 3 months.

Whether you are shifting to a new home or your lights have burnt off out and you need to buy new ones, you should buy the lights in large. Purchasing places you in a better place to be provided discount rates thus preserving you a lot of cash. There are two primary locations where you can buy the lights from: on the internet and in the nearest shopping center. Each of the locations has its own pros and cons and you should think about them before creating your buy. Whether you want to buy the lights off-line or on the internet, one factor you should be careful of is the authenticity of the shop or website you buy from. As principle, you should always do adequate analysis and recognize a reliable website or shop before you aspect with your cash. Buy led bulbs in bulk
