Over the last 5 years, the price of new wind power in the US has dropped 58% and the price of new solar power has dropped 78%. Utility-scale solar in the West and Southwest is now at times cheaper than new natural gas plants. Even after removing the federal solar Investment Tax Credit of 30%, a recent New Mexico solar deal is priced at 6 cents / kwh. By contrast, new natural gas electricity plants have costs between 6.4 to 9 cents per kwh, according to the EIA.

TOO BAD YOU CAN'T BUY a voodoo globe so that you could make the earth spin

It's not just the fixed wiring and the pristine new installations with anti-arc switches.
Power leads and extension cords are often flexed until they go dead. If they go dead while operating, your house burns down.
Radiators and other resistive loads don't care whether it is AC or DC. If you have DC at the same voltage as AC you are going to get semi-knowledgeable idiots converting them over. In most cases it will be as simple as swapping a plug. They will even work for a while until they burn the house down.
In theory it could work. In practice high voltage DC in an average home environment is a bad idea. It will burn the house down.
If you cough while drinking cheap red wine it really cleans out your sinuses.
