DIY CHEAPEST Solar Panel System Ever Part 2


Solar panel update video with the cheapest solar panel system ever. See how you can use solar power at your house NOW. see part 1

What is one key advantage of using hydropower as a source of energy?

Question:

What is one key disadvantage

[Guardian] Harnessing wave power 2008.09.26


The world’s first commercial-scale wave-power station has gone live off the coast of Portugal. This footage shows how the 140m-long snake-like devices work.

What is the Importance of having wind power in Quebec?

Question:

I know that Quebec is starting to use tons of wind power but… What is the Importance of having wind power in Quebec?

What is capacity hour rate for solar power batteries?

Question:

I’m looking a battery for use with solar power and it has the following specs.

Volts 12
Capacity @ 20-hr rate 120
Capacity @ 100-hr rate 145

How does this translate into running a 1000 watt appliance and how long you can run it with this battery.

What would be the fate of large hydropower projects in next ten years from now?

Question:

Hydrogen cell is a very big contender as alternative fuel or energy source. High energy demand and price would compel the automobile industry to change their flow sheet soon, similarly energy promoters would cease to invest in large hydropower projects due to availability of cheap energy from hydrogen cell. Can we say that large hydropower projects and proposals have bleak future in coming years and we should go for smaller hydropower projects which can be completed in 5-6 years and also have small physical and financial layouts. Small hydropower projects can be planned on Total Integrated micro watershed basis to have least or Zero adverse impact on environment as well as settlements & existing infra-structure. By the time hydrogen cell and other alternative energy sources replace thermal & hydropower mix energy, the small hydropower projects can supplement the energy demand in shortest possible time frame.

Alternative source of energy – How to utilize wind-power?

Question:

What would be cheap available solution to pump water 40 to 60 foot high. Can I build something to utilize wind power or solar power and some technique to lift water cheap? I like to use as little money as possible for this task.

Students Use Car Parts For Solar Power


MIT students use car parts and plumbing supplies to produce heat, electricity and cooling for developing countries.

What country is the number one producer of hydropower?

Question:

Its just a little extra credit question that I can’t find the answer to and need your help! thankssssss!!

REGENEDYNE Wind Turbine


www.Regenedyne.com Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine. *Efficient Frictionless Power Generation with less maintenance, compared to HAWT. No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.
