There are many import properties of battery, which I don't see mentioned. They talk only about energy density and safety. - What is the Power Density? If it can only charge and discharge slowly, then your Tesla becomes slow and not fun

I basically only see to-do list apps for new frameworks. So therefore frameworks can only make to-do lists.

It's really going to be interesting when EV drivers start getting charged per mile. We'll have to figure out something to make up for the missing gasoline yeah revenues. And it is probably already becoming substantial in Californi

I think there is a sweet spot in high enough population density and low enough bureaucracy (or enough local gov cooperation).

Good research lab solar cells are 40% when actively cooled and concentrating light at 1000x. Good solar panels for homes and solar farms are 15 to 22% efficient.

Now your window needs wiring. And an inverter. Would be more effective to coat it or tint it or put up some blinds.

PV energy payback is typically on the order of 1 or 2 years.

Really dumb article. Photovoltaics are breaking through as we speak. 1/3 of new electricity generation capacity in the US was solar in 2014. Building integrated PV is not doing anything, and I suspect it never will, because why??

I am signed up with this, but will probably unsubscribe soon, since it is getting really annoying. Between spam and people who just post unrelated google queries.

The fact that Hibernate Query Language even exists tells you that ORM is a bad idea.

What do you mean it works best when there's less load? Solar works best when the sun is shining, and that is when the demand for electricity is highest (especially in places with air conditioning).

Yeah, this "breakthrough" has the potential to one day to produce electricity at a cost that conventional PV already delivers. http://www.greentechmedia.com/articles/read/Austin-Energy-Sw... I would neve

This piece overlooks the fact that utilities can install solar power cheaper than a residence can. This will always be the chase. Electricity will drop in price accordingly.

How about this math 11,000 million dollars per year divided by 115 million households, divided by $70/ month, divided by 12 months per year. That's 11% percent of households to break even? 65% of adults already have broadband at home in the

SMA, a big German inverter company, shows the daily amount of PV generated in the country. Today, they hit nearly 18 GW. I'll bet they have at least one 30 GW day this year, once the sun finally comes out. http://www.sma.de/en/company/pv-e

Just model the grid as a battery in your head. Just because the grid is really bad at storing energy now, doesn't meant hat this won't change soon. And that's not Apple's problem. All the energy that they produce and put on the grid is ener

PV is coming down in cost precipitously. Energy companies are buying huge PV farms. Their cost of energy will drop. Utilities are regulated to limit their rates to guarantee minimum profitability, so their price must be correlated to their

The world's 4th largest economy was over 40% powered by solar for two days in May this year. I think we can consider the innovation in PV technology a game changer that will impact the way we live greatly. Imagine a world with 0 fuel costs

I wish I had read this and thought about it a week ago, before I decided to teach myself golang, which ate up my free time. Is learning an experimental unpopular language going to help me win? Fat chance.

Again, you have this 180 degrees backwards. There was a huge rush to build out polysilicon module fabs in China that has caused a huge oversupply. Now module manufacturers are going out of business daily, leaving an oversupply of polysilico

The price of polysilicon, the stuff that a large portion of commercially available solar panels use, is NOT increasing. In fact, just the opposite has happened. If you want to know why Solyndra really failed so dramatically, you need to und

It's mind boggling that a programming language from Google would be given a completely unsearchable moniker.
