Build a Dyson Sphere and make $188 septillion/year

Is it true that you can get 4kwh per day per square meter? My average electricity consumption is ~15kwh/day, so if I can potentially offset most of my grid usage with just 4 square meters of solar panel, that seems very attractive. I live in a tropical country btw.
-
No, 4kwh is about the daily amount of sun hitting 1 square meter. Solar panels can capture about 20% of that
-
Over the past year I'm averaging about 1.1 kwh per day per square meter on my system.
-
i would imagine living somewhere tropical might be even better

And if you follow, there may be a tomorrow
But if the offer's shunned, you might as well be installing solar panels on the sun
-
So don't delay, act now! Supplies are running out
-
Allow, if you're still alive
Six to eight years to arrive in low solar orbit

Argh I hate how they never show installation costs upfront...
People think the cost of the panel is the most expensive, but it's actually the 151 million km copper cable
Why can't we just wirelessly transmit the power, maybe have it hit a collection device that can harness about 4 kwh/m^2/day
Copper wouldn't cut it, too much resistance. You need a superconductor... only problem is how to keep it cold enough at below 1000C.
