Comment Re:Heat networks are inefficient (Score 2) 35

Heat can be stored seasonally for district heating. This is one of very few reasonably cheap ways to make power demand flexible on a monthly basis. Heat pumps on their own typically need to run at the time that heating is required, no matter how expensive electricity is. In Denmark, more than half of all dwellings are heated with district heating. It is not a niche technology.

The additional advantage is that it is quicker to change heat source. Industrial heat, waste incinerators, biomass, solar, and heat pumps all feed into the same system, and when new technologies become available, you do not have to switch every house to a new system.

So you want a 50% income tax on top of existing income taxes for incomes above $10k, until you hit $48k, where the tax rate drops by 50 percentage points.

This creates exactly the problem that UBI was invented to solve: that lower incomes experience high effective taxation, sometimes above 100%.

You should really read before ranting.

"In 2020, renewable energy sources (including wind, hydroelectric, solar, biomass, and geothermal energy) generated a record 834 billion kilowatthours (kWh) of electricity, or about 21% of all the electricity generated in the United States."

21% of generated electricity, not 21% of capacity.

Comment Origins of Free Software (Score 4, Interesting) 118

Perhaps it is time to look at what originally caused the Free Software movement.

Richard Stallman worked at MIT Artificial Intelligence Laboratory which bought a new laser printer. This printer was shared across the laboratory, and so sometimes queues could be long. With the previous printer, Richard Stallman had modified the printer firmware to send a mail to the print job owner when the job is finished, and also to send messages when the printer jammed. However, the manufacturer of the new printer kept the firmware proprietary, so he could not make the change. Even if he had been able to do so, he would have been prohibited by copyright from sharing the improved firmware.

If the printer had been running Red Hat Enterprise Linux, Richard Stallman would have been able to get the source for printer firmware (but he would have needed to get the support login). He would also have been able to change the software, and he would have been able to share the fix.
