Recent rapid responses
Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on bmj.com. Although a selection of rapid responses will be included as edited readers' letters in the weekly print issue of the BMJ, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window.

Cheap and available technologies that save money and can reduce carbon emissions to zero already exist.
Instead of using fossil fuels, we can convert vehicles to compressed air or even water electrolysis propulsion. 
Factories, buildings and houses can stop using fossil fuels for heating and electricity and convert to take advantage of U.K.’s huge geothermal potential. 
These technologies are safe, cost-effective and available for sale.
 Cars that can move cheaply on compressed air!
 Cars that can move cheaply on salt water!
 Widespread geothermal potential!
