Comment Bad math and bad economics (Score 1) 296

Does anyone else see a problem with their math?

The headline indicates that six Leaf cars can power the building. Later they say the scheme reduced peak power load by 2%. Doesn't that indicate it would take 6*50, or 300 Leaf cars to power the whole building.

This sort of fuzzy math makes me doubt most of the solar and wind claims.

Another post is heavily in favor of net-metering, where the utility pays you the same rate per KWH as they sell it to you. That's bad economics. That means you can buy power at peak periods and have them buy from you at off-peak. You're asking them to be your energy storage source at no cost. If everyone did that, the utility would go broke trying to keep generator plants available (at zero cost) for when the sun doesn't shine or there's a hot day with a large air conditioning load.

It takes an interesting mind to watch thousands of 5-passenger cars go by with a single occupant and not think that carpooling is a solution. Just one additional passenger will double the capacity of the road.

And there are millions of packets going by on the Internet. Just think, if every other packet were concatenated on the previous one, there would be half as many packets, and that would double the capacity of the routers.

Our model we've discussed at work is that PCs are for content creators and tablets are for content consumers.

Very few people program or develop complex spreadsheets on tablets. Those users typically use laptops or desktops (whether MacOS, Windows or Linux).

People on tablets review spreadsheets, read web pages and read/reply to email.

In my experience, very little content is created on tablets.

That may mean that 90% of the users will be fine with a tablet, but there will still be a place for the desktop/laptop. The downside for us content creators, if that happens, is the price will go up as we become a specialty market rather than a mass market.
