Journalists bemoan the poor understanding of science by the general public, and then have the hypocrisy to publish articles like this report on th BBC.

The piece is about the much anticipated presentation by Elon Musk, about Tesla's new battery technology.

It repeats figures from the presentation about the performance improvements that the new battery tech. offers. In short, the new batteries will have:

1. 5 times more energy storage,
2. 6 times more power,
3. 16% more vehicle range.

Item #1 should translate directly into 5 times more range. The only reasons that it wouldn't are:

• If the batteries are hugely heavier than the current batteries (normal matter is simply not dense enough to cause this - only neutron stars are dense enough);
• Or if Tesla are going to significantly reduce the number of batteries in each car, to take advantage of the increased energy density, but there is no mention of such a reduction in the report;

Either the journalists at the presentation were so mesmerized by it all that they didn't challenge this inconsistency, or they did, but the author of the BBC article (James Clayton) understands so little about basic science that he ignored this glaring issue.

I expect such poor journalism from some publications, but I had higher hopes of the BBC.
