Rated power output (AC):	100 kW&lt;p&gt;Figure fuel costs of $10 per MMBtu. So it pumps out 100kW/hr electricity for $6.60.&lt;p&gt;~$0.09/kWh for electricity in Oregon (its double that for NYC). So we pay about $9 for 100kW/hr.&lt;p&gt;Thats a 30% savings in Oregon and about 70% for the East Coast. But it still releases a lot of CO2 - 773 lbs/MW-hr.&lt;p&gt;&lt;a href=&quot;http://www.bloomenergy.com/products/data-sheet/&quot; rel=&quot;nofollow&quot;&gt;http://www.bloomenergy.com/products/data-sheet/&lt;/a&gt;&lt;p&gt;So if you ran one straight for a year and you used all its output, it would save $20k-$40k depending on electricity prices. So if they can get the price sub $100k and natural gas supply and price stays even, they could sell a lot of them.</text><parent_chain></parent_chain></comment><story><title>Bloom Unveils Its Game Changing Energy Box</title><url>http://mashable.com/2010/02/24/bloom-box-launch/</url></story>

One of the examples they give is using these to charge your hyrbid car. So, by the transitive property, aren&apos;t you putting fuel into your car?&lt;p&gt;I guess I&apos;m trained to think of alternative energy sources like sun and wind, so I&apos;m thrown off here. What&apos;s the innovation?&lt;p&gt;I can see that you&apos;re generating electricity locally, which I guess means we could get energy to places without running power lines. But reading the article, that doesn&apos;t seem like the point of these.&lt;p&gt;The article does claim that the energy is more efficient than what you get on the grid. But if that&apos;s the case, why don&apos;t we just put a ton of these onto the grid and push down the cost of electricity for everyone?</text><parent_chain></parent_chain></comment><story><title>Bloom Unveils Its Game Changing Energy Box</title><url>http://mashable.com/2010/02/24/bloom-box-launch/</url></story>
