Alternative energy and environmental projects. Like to join in?
« on: December 27, 2010, 07:44:22 PM »
I have done several alt energy projects over the years.   Official research is now controlled by corporations so even though this is humanitarian for the most part, there is conciderable resistance to actually testing it.  (The pulser pump got preliminary testing in a university (it works)  but it took 20 years!)
 I already knew that it worked and thought they might build a bigger and better one.
They didn't.
Pulser pump Low tech river or stream powered pump with no moving parts.

Dripper trackers   Low tech solar tracking for equatorial mount.  Equatorial mount is the simple way to set up tracking for solar. Dripper trackers are the simple way to turn them.

Solar design t-square and clam shaped reflectors.  It took a lot of time to come up with a design process that is low tech yet yields better shapes for reflectors for unattended solar cooking.

Tracking solar accumulator project  This is the giant solar project that helped me start the mini projects associated with it.  (To solve the problems associated with it).

Bees.   I did the cob and stem bee vase on instructables to provide shelter and nesting sites for solitary bees

Windowfarms.  They use hydroponic drip gardens in windows with airlifted (by aquarium air pump) dripping water to provide nutrients. http://www.windowfarms.org/
I was asked for input about airlift and I did the biofueled  water pump. You can power it from fermenting beer or by an aquarium pump. I have even powered it from fermenting kitchen waste.  It has no moving parts.
http://www.youtube.com/watch?v=G6pfE_IxVgQ is a demo.
So lots of things you can do.  Repeating or improving on what I did boosts its profile and encourages others to try it.  Thanks Brian

Fascinating stuff Gaiatek, most especially the Bees. Such a funky looking shelter you built for them, I have sent that link to a friend who will be fascinated.
You need funding.

Japanese breakthrough will make wind power cheaper than nuclear 
 
And think of the millions upon millions of jobs that would be created building a 21st century energy distribution system free of the shackles of ever-diminishing fossil fuel supplies.

(yes, wind is free, but a national grid is not...)

That is a wonderful and promising breakthrough, but we need to study measures to protect birds and other airborne beings from their impact.

We must not forget that windmills are not the only human technology that harms airborne beings. Skyscrapers, especially glass ones lit at night, exact a horrific toll on them.

I'm sure that if we are serious about protecting other living beings, it can be done. The wars for oil have killed many non-human animals (remember the poor wild camels shelled and burnt in the first Gulf War?) and damaged many ecosystems, not just Alberta's.

I think the really large windmills have very slow moving fans. As for keeping birds away from the blades, the only thing I can think of at the moment are wind whistling devices - in other words, attach a small but high frequency whistle to the blades that would emit sound as they turn.

Goodbye nuclear power: Germany's renewable energy revolution
 
The country has vowed to unplug itself from nuclear power and embrace renewables. The world should be paying attention
