Welcome indoors, solar cells

Scientists have developed organic solar cells optimized to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.

Yang Would Spend $3 Trillion On Residential Solar, But The Same Money Could Decarbonize The Grid Entirely

Yang’s single largest dollar expenditure, 62% of his US$4.9 trillion budget, would only impact 2% to 5% of US energy consumption. And his investments on geoengineering, fusion, and thorium nuclear generation are purely wasted expenditures

Porsche Taycan — Power Hungry, Slower To Charge Than Tesla Model S (Most Of The Time)

All rights to Simon Barke /CTAfter the unveiling of the new Porsche Taycan yesterday, analysts were quick to call the only electric competitor (the Tesla Model S) “ancient in comparison,” pointing out the “pathbreaking” 800 volt system that “slashes recharging times.” It is true that a higher system voltage can reduce charging times: you can feed more power to the battery without increasing the charge current. But just how good is Porsche’s implementation

My Car Expenses The 15 Years Before Tesla

I’ve had an obsession with financial software for some time, something that I probably inherited from my father. I remember when we got our first Apple II in 1978 and he used it for investments and budgeting. When he moved to an IBM PC (which I bought for him at a discount since I was an IBM employee from 1984 to 1998), he fell in love with Managing Your Money. I moved to Quicken in the mid 1990s. I’m trying to spend less time tracking my finances and more time writing, so I’m moving to more cloud-based methods of tracking my finances. But I noticed that I had 15 years of data on my auto spending available as part of this obsession. I didn’t have it easily tied to my 7 cars, but don’t think of this as a review of any car, but as a general survey of the fuel, maintenance, and repair cost for 7 cars over about 400,000 miles

Defrosting surfaces in seconds

Researchers have developed a way to remove ice and frost from surfaces extremely efficiently, using less than 1% of the energy and less than 0.01% of the time needed for traditional defrosting methods. Instead of conventional defrosting, which melts all the ice or frost from the top layer down, the researchers established a technique that melts the ice where the surface and the ice meet, so the ice can simply slide off.
