Damn dat idee heb ik ook, alleen dan met even dobberen ergens om bij te tanken, en een heel goede dynamo die op waterstof werkt. Pay me, pls. patent pending.

Ik vind de 'Body' verdacht veel op deze lijken...
  Ik heb deze jongen in het echt mogen zien. Staat gewoon in een museumpje stof te happen. De lijnen van deze kist (aerodynamisch) zijn heel apart om te zien. Vooral op de vleugel-tip...   Let goed op de vortex die de body genereert, heel mooi om te zien op de volgende foto...  http://nl.wikipedia.org/wiki/Lockheed_SR-71_(Blackbird) |

De straalmotor die werd gebruikt is ook apart. Deze heeft een beweegbare 'cone' die bij verschillende snelheden andere positie's aan neemt, zodat de 'air-flow' in de motor anders word omgeleid...
 The J58 was a variable cycle engine which functioned as both a turbojet and a fan-assisted ramjet. Bypass jet engines were rare at the time, but Ben Rich later described the engine as "bypass jet engine by air withdrawal".[3] At Mach 3.2, 80% of the engine's thrust came from the ramjet section, with the turbojet section providing 20%.[4] At lower speeds, the J58 operated as a pure turbojet... http://upload.wikimedia.org/wikipedia/commons/8/89/SR71_J58_Engine_Airflow_Patterns.svg The J58 is a hybrid jet engine: effectively, a turbojet engine inside a fan-assisted ramjet engine. This was required because turbojets are inefficient at high speeds but ramjets cannot operate at low speeds. To resolve this, the airflow path through the engine varied, depending on whether ramjet or turbojet operation was more efficient, thus the term variable cycle. To create this effect, at speeds over 2,000 mph (3,200 km/h) the nose cone of the engine was pushed about 2 inches (5.1 cm) forward to improve the air flow in the ramjet cycle...

KillaCycle® facts: 0-60 mph (0-96 km/h): 0.97 seconds Acceleration: 2.89 G (almost 3 times free fall) Best Top Speed in ¼ mile: 174.05 MPH Lowest ¼ mile Elapsed Time (ET): 7.82 seconds @ 168 mph Power: over 500 hp Battery: 1210 lithium iron nano-phosphate™ cells from A123 Systems Battery weight: 200 lbs (90 kg) Battery voltage: 374 Volts Battery capacity: 9.1 kWh High-current cell interconnect tabs welded with Miyachi-Unitek equipment Motors: Two DC series motors @ 87 lbs (40 kg) each. Bearings: All of the bearings are supplied by NSK. The highest quality bearings are a must in drag racing! Controller: Cafe Electric Zilla2k-HV Drive: direct chain drive on the rear wheel. Total weight of the bike: 653 lbs (296 kg). Electricity consumption: 0.6 kWh, worth $0.07 for each run down the strip including the burn out. It corresponds to 2 ounces (70 ml) of gasoline. Charger: Manzanita Micro PFC-50, 12kW power-factor corrected, multi-voltage input Tires: M&H Racemaster 10.0/27.0 - 15 MHR-68 Printed Circuit Boards: Advanced Circuits (Please type “KillaCycle” in refferal box or comments if you order PCBs!) Including burn-outs, the KillaCycle could make 7 or more runs on one charge. Recharges each single run in less than 4 minutes. KillaCycle® is silent aside from the chain and some tire noise. Owner: Bill Dubé - billdube@killacycle.com Driver: Scotty Pollacheck If you think about it, the KillaCycle® is just a giant cordless drill with wheels! www.experimentalaircraft.info/articles/aircraft-engine-performance.php Als ik dit zo lees hadden ze allang electrische vliegtuigen kunnen bouwen met een of ander klein laboratorium als motor. Wet van behoudt van energie kan over wonnen worden door momentum, zelfde als een turbo charger, bepaalde intake bewerkstelligen, kan je best lekker cruisen.
