    I've read over the last 40 years, yet to be tested Real World

    Some researchers contacted by Chemistry World questioned whether the technique would be useful for commercial batteries. 'The most appealing result is obviously the high cycling capacity that these materials are able to deliver,' said one leading expert on lithium battery anodes, who asked not to be named. 'However, the test is limited to only 10 cycles and this is far too few to determine the industrial impact of the electrode. Also, the rate of the cycling test is very low and thus the power capability, another important practical requisite, has not been ascertained.'

    Urban rooftop both often suffer from shadowing from other buildings and being on building with a much higher demand to area ration than exurbian single family dwellings.

    Solar need collection area oriented towards the sun, wind needs to get up above the ground.  Putting big solar arrays on wind turbines is very much like putting large sails on them, the arrays would be highly stressed and frequently damaged. On top of that they'd be harder to install and maintain that ground level solar; plus most of the best places for wind power are less than optimal for solar - fairly far north, in mountainous regions, in areas with frequent cloud cover.
