Why I am making the change

[BobCajun]

I'm still waiting for COB technology to get cheaper. Standard LED "bulbs" that used to cost $20 are now selling for $5, and I believe the same thing will happen with COBs.
It's a technology thing involving mass production efficiency. Similar to computer tech in the 90s. Remember when a decent laptop cost $10,000+? Now they are less than $1,000.
Not sure when it will happen, but it's coming.
And when COBs are cheap, old gear will be completely worthless. All those old reflectors should recycle nicely...

Yeah that's why when I converted a veg chamber from cfl to LED I just put 10 Sylvania/Osram 100w replacement LED bulbs in there instead of buying COBs or inFlux linear LED strips. Even including the cost of 10 lamp holders, about $2 each, it was still less than a dollar per watt, about $100 total for 140w, while COBs are still at least $2 per watt. The bulbs worked great too. 10 of them in a 0.5 sq meter chamber was just right. At 14w each, 140w. So 280w/ sq m. Plus if they burn out it's quick and easy to get replacements. Just head on down to the hardware store. Aside from a fair amount of wiring being involved, it's the cheapest route to LED lighting available.

Nope, less than 20 yrs

in 20 years solar will be so cheap nobody sane would invest large sums in a big power plant. why would anyone want power from a provider if one could just get it for free on the roof?

Fusion power is just a few years away...

And always will be.

Sorry ty - the cheapest fusion power source is the sun - and only 8min. away.

In my religion she is in the center - and master of desaster and fertility.

She is the only GOD for plants and animals like us
- don`t believe in the stupid popes and other religions and theories -
as long as they pretend to play a more important role than she.

There is an effect called "albedo" -
The Albedo is a measure of the brightness of a body. The brighter the body is. The bigger the albedo. An important consequence is that the brighter the body is, the more the light is reflected ( "returned").

If you calculate the difference in energy balance of a white - and a black-painted sqmeter.
you will see that with 1 white sqm and 80 cent for the white paint - you can dimm the sun power

~ 35000KWh during the next 10 years. - So politics is not only criminal but also stupid.

"My" sun will kill you all easiely - if you keep on ignoring, that oil, gas, coal and wood is
nothing else than stored sun energy.
The Mayas and all the other sun-cultures will laugh till down their graves.

I'll be 70 then and I'm damned sure we won't be cutting any ribbons on fusion based power plants by then.

I'd love to be wrong, but I'm not.

You haven't contradicted me.

Solar, wind and wave power are the present AND the future. Efficient use of energy as well as biological sources also figure prominently.
