But the bulk of the conversion cost comes from adding a roof to cover the entire stadium, which would also involve moving the distinctive floodlights.
This means that the cost of conversion plus the cost of storage will have to be similar to the cost of providing energy on demand from the energy stored in chemical or nuclear fuels.
FORBES: Storage, Not Generation, is the Challenge to Renewable Energy
The conversion could cost even more if the various technologies developed for functions such as encryption and compression are not compatible with each other.
If the builder already installed a driveway and garage doors (drywalling behind them), the conversion might only cost a few hundred dollars.
The big challenges are the high cost of a conversion plant and their technical complexity.
The cost of organic conversion and lower crop yields than regular cotton (at least in the early years after a switch) have quelled farmers' interest.
ECONOMIST: Ethically minded shoppers turn their focus to cotton
Google notes that a site called ApartmentHomeLiving.com, which displays apartment listings, has seen an almost 50% increase in the number of conversions, with a cost-per-conversion 73% below traditional search ads.
And driven customers don't seem to be letting cost discourage them from the conversion.
Dr. Davis has offered to provide at no cost to the government the conversion of 100, 000 lines of software code on a mainframe computer to demonstrate his program's abilities.

Clearly, though, the Bloom Box is still not a zero emissions tech and would only cut emissions by roughly 50% relative to the national average, unless it runs on landfill gas or biogas or hydrogen from electrolysis fueled by zero-carbon electricity (which would be much more expensive as you have to add cost of electrolysis unit, higher cost electricity, and about 30% conversion losses in electrolysis).

Another explanation for any difference between how much items cost and what actually appears on a credit card statement is Dynamic Currency Conversion.
Odds are, the only conversion likely to result from such assistance will be to ensure that Moscow retains, perhaps at lower cost, this indispensable instrument for threatening the West.
CENTERFORSECURITYPOLICY: Help With Soviet Conversion Is Risky
Conversion of natural gas to methanol, as widely practiced in the chemicals industry, could provide a cost-effective route to manufacturing an alternative, or supplement, to gasoline, while keeping CO2 emissions at roughly the same level.
